1782 (203-1664) ~ ~ DEVICE FOR SURGICAli ~PPARATU~:
1. Te~ h~ Field The t~nhn;~A7 field relates generally to 10 surgical i~ L~ and, more particularly, to an insertion device for use with a surgical tissue fastening apparatus .
2 . De~criPtion of Related Art During certain surgical ~LvceduLe:s, it is often n~ qqAry to insert one or more surgical in,lL, ts into a body cavity through a natural opening or orifice. For example, in surgical procedures involving hollow organ tissue sections, such as colon surgery, it is often 20 n~AoqqAry to remove a diseased or damaged hollow organ tissue section and insert a surgical apparatus trans~
anally in order to reconnect the healthy tissue sections.
In one known method of reconnecting the healthy tissue ~ tinnA~ a surgical tissue fastening apparatus 25 such as a surgical stapler or multi-part surgical fastening device having a staple ~A3;nAh;n~ anvil or corresponding component of a multipart fastener installed on a distal end thereof is inserted trans-anally. See, for example, U.S. Patent No. 5,119,983, the contents of 30 which is inCuLt,oLclted by reference. The staple clinching anvil, or corr~qpnn~7ing component Qf a multi-part surgical fastener, is inserted through the colon, past the ~7; qAAA~d tissue section and prepositioned within the healthy distal colon section. The anvil or multipart 35 fastener is ~7;AAnnn~cted from the tissue fastening apparatus and the tissue fastening apparatus is removed from the body. The diseased section of tissue is excised and removed from the operative site and the surgical ti6sue fastening apparatus is reinserted through the rectal stump up to the distal colon section. The shaft of the anvil or multipart fastener is then reconnected to a center rod of a surgical tissue fastening apparatus and 5 the center rod is retracted to approximate the anvil towards the fastener cartridge of the surgical tissue fastening apparatus thus bringing the healthy ends of the distal colon tissue section and rectal stump into abutment for fastening. The surgical stapler or surgical 10 fastening apparatus is then activated to staple or otherwise fasten the rectal stump to the distal colon tissue section and the surgical tissue fastening apparatus is thereafter removed trans-anally.
In certain tissue fastening i~ LLI Ls, such as that disclosed in ~. S . Patent No. 5, 005, 749, the contents of which is incorporated herein by reference, a safety ---hAn;~-n is provided to prevent activation of the fastening apparatus i.e., ejection of staples or compression assembly of multipart fastener, ~ ~~ts, prior to minimal approximation of the anvil or fasteners to the fastener cartridge of the apparatus. Upon sufficient retraction of the center rod and anvil or fasteners the minimum distance, the safety ~-~hAn;~m is disabled and the surgical tissue fastening apparatus can be fired. As disclosed in U.S. Patent No. 5,005,749, should, for example, the anvil, and thus the center rod, be retracted less than the predet~l~m;nl~d minimal distance, the safety T- hAn;~'n will remain enabled and prevent activation of the ina~L 1_.
One recent article has suggested that, to facilitate re-insertion of the stapling apparatus after pl A~ L of the anvil, an old, used stapling anvil can be attached to the stapling apparatus so as to provide a blunt surface as the stapling apparatus is advanced through the rectal stump. While providing a smooth surface over the staple cartridge may ease insertion, the use of an anvil, particularly one not originally provided with the stapler, is not advisable. For example, despite attempts to sterilize a used anvil, the potential inherent risks and danger of cross-contamination by this proposed procedure are apparent. In addition, if an anvil other than one supplied with the surgical stapler is mistakenly used to clinch the staples during the procedure, there is a risk. that the staples will become malformed. Also, insertion of the stapler with an anvil closely approximated after already placing the original anvil in the body may result in an inadvertent firing of the stapler.
An alternative method and device for inserting a surgical stapler part way into the rectal stump trans-anally is disclosed in U.S. Patent No. 5,404,870 and includes a sheath open at both ends and having members which retain the sheath near 'che rectal opening. The surgical stapler is inserted through the sheath and out the distal end thereof. While the device disclosed in U.S. Patent No. 5,404,870 may, to a limited extent, aid in inserting a surgical stapler through the rectal opening, the device is of a fixed length and may not extend sufficiently far into the rectal stump to shield the surgical stapler as it is advanced to the operative site. Addi~ionally, the device remains positioned within the rectal stump during the entire surgical yL~ct~duL~ and may be a source of irritation and/or a ml; C:~n~e to the surgeon .
Thus, there is a need for a safe and efficient insertion device to facilitate entry and movement of a surgical tissue fastening apparatus trans-anally through and up to the desired surg~cal site.
S~ RY
An insertion device is provided to facilitate atraumatic insertion of a surgical instrument into and through a body orifice. In a preferred embodiment, the 5 insertion device includes a head having an atraumatic leading surface and a shaft extending from the head. The head is anvilless and thus devoid of staple rl;nrhin~
structure. The shaft can be formed separately or molded integrally with the head. The head preferably has a 10 diameter substantially equal to or greater than the maximum diameter of a distal end - of the surgical tissue fastening apparatus used therewith. The head shaft can be solid and insertable into a tubular center rod of the surgical staple (see, for example, ~.S. Patent No.
5 ,119, 983 ) or the shaft can be hollow ana slidable over a solid center rod of the surgical staple (see, for example, U.S. Patent No. 5,205,459). In either case, either the shaft and/or in~l L center rod is provided with att~ L structure for attachment to the surgical 20 stapler. Preferably, the attachment structure is a circumferential groove adjacent an end of the solid structure .
The la~ i crl Oq~ insertion devices can also provide a lockout function when used with surgical tissue~5 fastening apparatus incvl~vlclting retraction based safety rh in;~ These r-~hi~ni require that a center rod be retracted a predet~n; nl~ minimal distance before the apparatus can be fired. The shaft of the insertion device is lal;r ~ nl~d and configured such that the head 30 of the insertion device will contact the fastener cartridge at the distal end of the apparatus prior to retraction sufficient for firing.
In another preferred i -a;r~nt of the insertion device, the anvilless head is provided with 35 :,LluL:Lur ~ to protect and retain staples contained within staple pockets of a surgical stapler. The structure can include projections, preferably arranged in C~ C~ LiC
rings, each of which extend into a corr.oqr~n~; n~ staple pocket of the surgical stapler to protect and retain the staple therein. Preferably, the shaft is provided with 5 alignment structure in the form of a plurality of longitudinal ribs. The ribs engage c~LL-~l,J .l;n~
structure on the surgical tissue fastening apparatus and ensures proper ~ ; L of each of the proj ections within a corresponding staple pocket. Additionally, a 10 circumferential flange can be provided that extends proximally from the head to overlap the distal end of the surgical tissue fastening apparatus thereby further shielding the staple cartridge.
In another preferred embodiment, the anvilless insertion device can have one or more recesses disposed therein to reduce weight and help prevent undesired suction effects.: -BRIEF l~S~ OF T~E DR~WINGS

nR'r~TTRr ~E~ OF ~K~ r~M~
Referring now to FIGS. 1-3, and initially to FIGS. 1 and 2, there is shown an insertion device 10 for 3 0 use with surgical tissue fastening apparatus such as those disclosed in, for example, U.S. Patent Nos.
5,005,749 and 5,119,983, the entire disclosures of which are incorporated by reference herein. nhile the following discussion of the various ~ - ts of the insertion device is given with respect to a circular surgical stapler in general and, in particular, an anastomosis surgical stapling inDL~, -nt such as that di6closed in U.S. Patent No. 5,005,749, it will be noted that the insertion device is equally applicable for use with multipart surgical fastening devices such as a fragmentable anastomosis ring applier disclosed in U. S .
Patent No. 5,376,098 or the like. As used herein the term "distal" refers to that part of the device, or c _ r~nont thereof, furthest ~rom the user, while the term "proximal" refers to that part of the device, or ~ -n,~nt thereof, closer to the user.
Insertion device 10 is ,1~; gn ~d to provide a smooth leading surface for trans-anal insertion of the surgical tissue fastening apparatus and generally includes head 12 and a shaft 14 extending proximally therefrom. ~ead 12 is monolithically formed and has a smooth atraumatic leading or outer surface 16.
Preferably, head 12 has a rounded distal end 18 and relatively rounded off proximal end 20 adjacent shaft 14.
Both head 12 and shaft 14 are preferably fabricated from a biocompatible material.
A head extension 22 is preferably provided int~ te proximal end 20 and shaft 14 to provide a smooth transition therebetween. It should be noted that both head 12 and head extension 22 are anvilless, that is, devoid of any staple ~1 ;n-h;n~ structure such as, for example, a ring of staple r,l ;n~-h;n~ buckets. Shaft 14 generally includes a shaft barrel 24, a distal end 26 of which is inserted and affixed within a bore of head 12 and/or head extension 22. Alternatively, shaft 14 and head 12 can be integrally formed or molded. Shaft 14 preferably includes a conical tip 28 formed on a proximal end 30 of shaft barrel 24. Alternatively, the shaft can be hollow as discussed in greater detail with respect to Fig. 12.
In order to facilitate attachment of insertion device 10 to a surg ~cal tissue fastenins apparatus, att~hl nt structure, preferably in the form of a radial recess or groove 32, is formed in shaft barrel 24 at proximal end 30 thereof and adjacent conical tip 28.
Groove 32 is ~l;r--lc;~npd and configured for detachable elly~y -nt with corr~sr~nri; n~ retaining structure, such as that contained in a distal end of a center rod, provided in the surgical stapling in:,Ll, L (not shown).
As noted above, head 12 is preferably formed as a solid monolithic structure. Preferably head 12 has a maximum radius subst~n~;~lly equal to the maximum radius of a distal end of the surgical stapling in,L, ~.
Head 12 can be formed by various methods, such as, injection molding of a suitable biocompatible plastic, for example. Additionally, shaft 14 can be molded integrally with head 10 or can be formed as a separate structure .
When shaft 14 is formed separately, it is preferably formed of stainless steel or plastic. Head 12 and shaft 14 can be assembled by inserting distal end 26 of shaft 14 in a bore of head 12 and/or head extension 22. Shaft 14 can be secured to head 12 and/or head extension by various means, such as, for example, a threaded interconnection or securing distal end 2 6 within the bore by means of a suitable adhesive.
As noted above, insertion device 10 is particularly ~ n-~cl for use with surgical tissue fastening apparatus employing a retraction ~r~n~lent safety ~ ;~m, such as, for example, the anastomosis surgical stapling ill~LL~ -nt disclosed in U.S. Patent No.
5,005,749 and 5,119,983. A retraction ~r~n~l~nt safety r~ n;~-m disables or blocks activation of the stapling in~ L until such time as a center rod, having a staple ~!l ;nl-h;n~ anvil affixed thereto, has been retracted to within a minimal pre~pt~rm;n~d distance from the staple cartridge disposed at the distal end of the stapling in:,Ll L. This prf~det~rm;n~d distance ensures CA 02202736 1997-04-1~
_ g that the sp~r.;f;r size staple will completely penetrate the tissue sections to be fastened and will be properly crimped by the staple ~l ;n-~h;n~ buckets of the anvil thereby preventing incomplete stapling of the tissue 5 sections. Thus, it is the center rod that must move the pr~d~t~rm;n~cl minimal distance before the safety r-~h~n; Fm is disabled.
The disclosed insertion devices and, in particular, insertion device 10 prevents firing when 10 installed on the stapling in~ L, L. Referring now to FIG. 3, this is ~ h~ by configuring and ~i---nRi~n;ng the length "L" of shaft 14 so that the center rod cannot be retracted to within the predet~rm;n~d minimal distance re~auired for firing.
15 Preferably, head 12 and/or head extension 22 abut a distal end of the surgical stapling in~L, -nt before the predet~rm;n~ minimal distance is achieved. Thus the surgical stapling in~LL, --,t cannot be activated while insertion device 10 is installed thereon.
Referring to FIG. 4, there is shown an anastomosis surgical stapling in~l L, ~ such as that disclosed in U.S. Patent No. 5,005,749. The in~LL, I
100 includes a yoke 102, a pusher tube assembly 104 which extends from the yoke 102 to carry a staple assembly 106 25 at the distal end, an anvil assembly lOg at the distal end of the instrument and an actuating r-~h~n;~m which extends from the anvil assembly 108 through the pusher tube assembly 104 to a wing nut 110 at the proximal end of the in~l_L, I for moving the anvil assem~bly 108 30 relative to the pusher tube assembly 106. In addition, a pair of handles 112 are pivotally mounted on the yoke 102. ~andles 112 are mounted so as to be manually grasped by a surgeon and moved towards each other, as indicated by the arrows in order to fire the staples (not shown) 35 from the staple assembly 106 towards the anvil assembly 108. A safety lock 114 is also mounted on the proximal CA 02202736 1997-04-1~
end of the yoke 102. Safety lock 114 is blocked from rotating out of the way of handles 112 until a center rod has been retracted a predet-ormin~od minimal distance in the manner disclosed in 13.S. Patent ~o. 5,005,749.
Referring now to FIGS. 5-8, and initially to FIGS. 5 and 6, there is shown an alternate embodiment of an insertion device which, in addition to performing the activation prevention and dl_Lallllldl_iC insertion functions described hereinabove with respect to insertion device 10, is particularly configured to protect and secure staples located in staple pockets of the surgical stapling instrument during insertion of the surgical stapling in~l L- I_ into and through a body cavity, such as, the rectal stump. Insertion device 34 is similar to insertion device 10 and generally includes a substantially monolithically formed head 36, devoid of staple ~-l inr~h;ng structure, and a shaft 38 ~rt~on~ing from head 3 6 .
Shaft 38 is similar to shaft 14 described above and includes a shaft barrel .40 preferably having a conical tip 42 at a proximal end 44 thereof. Attachment structure in the form of a radial recegs or groove 46 ig formed in the proximal end 44 of shaft barrel 40 to facilitate detachable engagement of insertion device 34 with a suitable surgical tissue fastening device in the manner described hereinabove with respect to insertion device 10. A distal end 48 of shaft 38 is affixed within head 36, or integrally molded therewith, in the manner described hereinabove with respect to insertion device 10.
Insertion device 34 is specifically configured to protect and retain staples within staple pockets of a surgical stapler during insertion of the stapler into and through a body cavity. Thus, as best shown in FIGS. 6 and 8, head 36 includes a plurality of proximally facing projections 50 extending from a proximal face 52 of head CA 02202736 1997-04-1~
36. Preferably, projections 50 are arranged in two staggered and concentric rings such as, for example, inner and outer rings 54 and 56, respectively.
Inner and outer rings 54 and 56 are arranged so 5 as to position a single projection 50 within a single staple containing pocket of a surgical stapling ina~L, L upon retraction of insertion device 34 adj acent the staple cartridge at the distal end of a stapling in~L -nt as will be described in more detail 10 below.
Head 36 also ;n~ tlec a circumferential and proximally extending flange 58 which is configured to overlap an outer edge of the distal end of an associated surgical stapling in .LL, -~t. Flange 58 inhibits debris 15 and fluids from entering the space between insertion device 34 and the distal end of the stapling ina~L~ L
and also provides for a smooth transition between the insertion device and stapler.
Referring to FIGS. 5 and 6, in order to aid in 20 Al ign;n~ projections 50 with cuLLe~ ullding staple pockets, shaft 38 includes alignment structure in the form of an ~l ;,j L sleeve 60 having a plurality of circumferentially spaced ribs 62. Sleeve 60 may be formed integrally with shaft 38 or separately, and secured to 25 shaft 38 by a suitable medical grade adhesive. Ribs 62 are configured to engage cOLL~L. ,-lin~ Al; j L
structure within a surgical stapler and thus ensure correct Al i 3 -nt of projections 50 with corresponding individual staple pockets upon retraction. Similar 30 alignment structure is disclosed in U.S. Patent No.
5,119,983.
Shaft 38 is preferably also provided with a high friction or knurled portion 64 to facilitate grasping insertion device 34 using known surgical 35 grasping inDLLI Lcltion and techniques.
CA 02202736 1997-04-1~
-- lZ --Referring now to FIG. 7, insertion device 34 is illustrated partially installed in a aistal end 66 of a surgical stapling inDLl, L 68. Surgical stapling instrument 68 includes a plurality of circumferentially spaced staple pockets 70 in distal end 66 thereof. Prior to stapling a tissue section, each staple pocket 70 contains a generally IJ-shaped staple 72 which, when driven out of staple pockets 70, through tissue sections and into a staple clinching anvil member, securely fastens tissue sections together. As shown, an inner surface 74 of flange 58 is dimensioned and configured to overlap an outer circumferential surface of distal end 66. ~hus projections 50, in combination with flange 58, protect and retain staples 72 contained within the surgical stapling in=.~L, L 68 when insertion device 34 is retracted adj acent to distal end 66 of stapling inDLL r~t 68 .
Referring now to FIGS. 9-11, and initially to FIG. 9, t_ere is shown another preferred embodiment of an insertion aevice. Insertion device 76 performs the actuation prevention and dLLdUllld~iC insertion functions described hereinabove with respect to insertion device 10 and generally includes a head 78, also devoid of staple rl 7nrhin~ structure, and a sha~t 80 integral with and extending proximally from head 78. Head 78 and shaft 80 are preferably monolithically formed of a suitable material, such as, for example, plastic. IIead 78 has a smooth, conical aLLdul,ldLic leading outer surface 82, while shaft 80 includes at~rht ~ structure, preferably in the form of a radial recess or circumferential groove 84, at a distal qnd 86 thereof. ~
Referring now to FIGS. 10 and 11, head 78 has a substantially flat proximally facing surfacq 88 oriented substantially perp~n~ i r~ r to a longitudinal axis of shaft 80. Preferably, head 78 is provided with a plurality of recesses or bores 90 extending from surface CA 02202736 1997-04-1~
-88 partially into head 78. Bores 90 serve to reduce the weight of insertion device 76 as well as reduce suction effects existing between tissue and a surgical tissue fastening device as insertion device 76 is extended and 5 retracted with respect thereto.
Similar to that of insertion device 10, shaft 80 of insertion device 76 is dimensioned and configured to be insertable in the distal end of a surgical stapling in~L, ~. The length "~1" of shaft 80 is also 10 ~l; r ~ n~-d and conf igured such that it prevents deactivation of a safety -hAn;~m when the proximal surface of head 78 is adjacent the distal end of the surgical stapling instrument.
With reference to Fig. 12, an alternate 15 preferred ' _ ';1- ~ of an insertion device is shown.
Insertion device 100 is similar to the previous embodiments, however, shaft 106 ~Y~n~l;n~ from atraumatic head 102 is a hollow structure adapted to receive a solid rod 110 extending from a surgical stapling in~ nt 20 (not shown). In this ' _~;r-nt~ the insertion device is secured to the stapling apparatus by inserting solid shaft 110 into hollow shaft 106. Solid shaft 110 preferably has circumferential recess 112 which is adapted to engage locking structure associated with the 25 insertion device shaft. Similar shaft connecting structures are disclosed, for example, in U.S. Patent No.
5,205,459 and can be applied to each previous embodiment disclosed herein. Returning to Fig. 12, the insertion device preferably has a smooth surface 104 devoid of 30 stapling forming pockets and shaft 106 has optional ~1;,; ~ structure 108. As previously described, shaft 106 can be fabricated to have a length sufficient to prevent disengagement of a lockout member which requires a predet ~rm;nprl longitudinal displ ~ ~ within the 35 stapling apparatus.
It will be understood that various modifications can be made to the o~horl; nts disclosed herein. For example, as noted hereinabove, the disclosed : ' 'ir- Ls are suitable for use with various surgical 5 tissue fastening in~,~L L:, and thus the specific att~ structure can be varied to ~cc -'-te the same. Additionally, the various '~O~l;T ~5 need not prevent activation of tissue fastening apparatus but can be dimensioned and configured to provide ease of 10 insertion only. Therefore, the above description should not be construed as limiting, but merely as ~ 1;f;cations of preferred -~; r ~-lt. q~hose skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
anally in order to reconnect the healthy tissue sections.
In one known method of reconnecting the healthy tissue ~ tinnA~ a surgical tissue fastening apparatus 25 such as a surgical stapler or multi-part surgical fastening device having a staple ~A3;nAh;n~ anvil or corresponding component of a multipart fastener installed on a distal end thereof is inserted trans-anally. See, for example, U.S. Patent No. 5,119,983, the contents of 30 which is inCuLt,oLclted by reference. The staple clinching anvil, or corr~qpnn~7ing component Qf a multi-part surgical fastener, is inserted through the colon, past the ~7; qAAA~d tissue section and prepositioned within the healthy distal colon section. The anvil or multipart 35 fastener is ~7;AAnnn~cted from the tissue fastening apparatus and the tissue fastening apparatus is removed from the body. The diseased section of tissue is excised and removed from the operative site and the surgical ti6sue fastening apparatus is reinserted through the rectal stump up to the distal colon section. The shaft of the anvil or multipart fastener is then reconnected to a center rod of a surgical tissue fastening apparatus and 5 the center rod is retracted to approximate the anvil towards the fastener cartridge of the surgical tissue fastening apparatus thus bringing the healthy ends of the distal colon tissue section and rectal stump into abutment for fastening. The surgical stapler or surgical 10 fastening apparatus is then activated to staple or otherwise fasten the rectal stump to the distal colon tissue section and the surgical tissue fastening apparatus is thereafter removed trans-anally.
In certain tissue fastening i~ LLI Ls, such as that disclosed in ~. S . Patent No. 5, 005, 749, the contents of which is incorporated herein by reference, a safety ---hAn;~-n is provided to prevent activation of the fastening apparatus i.e., ejection of staples or compression assembly of multipart fastener, ~ ~~ts, prior to minimal approximation of the anvil or fasteners to the fastener cartridge of the apparatus. Upon sufficient retraction of the center rod and anvil or fasteners the minimum distance, the safety ~-~hAn;~m is disabled and the surgical tissue fastening apparatus can be fired. As disclosed in U.S. Patent No. 5,005,749, should, for example, the anvil, and thus the center rod, be retracted less than the predet~l~m;nl~d minimal distance, the safety T- hAn;~'n will remain enabled and prevent activation of the ina~L 1_.
One recent article has suggested that, to facilitate re-insertion of the stapling apparatus after pl A~ L of the anvil, an old, used stapling anvil can be attached to the stapling apparatus so as to provide a blunt surface as the stapling apparatus is advanced through the rectal stump. While providing a smooth surface over the staple cartridge may ease insertion, the use of an anvil, particularly one not originally provided with the stapler, is not advisable. For example, despite attempts to sterilize a used anvil, the potential inherent risks and danger of cross-contamination by this proposed procedure are apparent. In addition, if an anvil other than one supplied with the surgical stapler is mistakenly used to clinch the staples during the procedure, there is a risk. that the staples will become malformed. Also, insertion of the stapler with an anvil closely approximated after already placing the original anvil in the body may result in an inadvertent firing of the stapler.
An alternative method and device for inserting a surgical stapler part way into the rectal stump trans-anally is disclosed in U.S. Patent No. 5,404,870 and includes a sheath open at both ends and having members which retain the sheath near 'che rectal opening. The surgical stapler is inserted through the sheath and out the distal end thereof. While the device disclosed in U.S. Patent No. 5,404,870 may, to a limited extent, aid in inserting a surgical stapler through the rectal opening, the device is of a fixed length and may not extend sufficiently far into the rectal stump to shield the surgical stapler as it is advanced to the operative site. Addi~ionally, the device remains positioned within the rectal stump during the entire surgical yL~ct~duL~ and may be a source of irritation and/or a ml; C:~n~e to the surgeon .
Thus, there is a need for a safe and efficient insertion device to facilitate entry and movement of a surgical tissue fastening apparatus trans-anally through and up to the desired surg~cal site.
S~ RY
An insertion device is provided to facilitate atraumatic insertion of a surgical instrument into and through a body orifice. In a preferred embodiment, the 5 insertion device includes a head having an atraumatic leading surface and a shaft extending from the head. The head is anvilless and thus devoid of staple rl;nrhin~
structure. The shaft can be formed separately or molded integrally with the head. The head preferably has a 10 diameter substantially equal to or greater than the maximum diameter of a distal end - of the surgical tissue fastening apparatus used therewith. The head shaft can be solid and insertable into a tubular center rod of the surgical staple (see, for example, ~.S. Patent No.
5 ,119, 983 ) or the shaft can be hollow ana slidable over a solid center rod of the surgical staple (see, for example, U.S. Patent No. 5,205,459). In either case, either the shaft and/or in~l L center rod is provided with att~ L structure for attachment to the surgical 20 stapler. Preferably, the attachment structure is a circumferential groove adjacent an end of the solid structure .
The la~ i crl Oq~ insertion devices can also provide a lockout function when used with surgical tissue~5 fastening apparatus incvl~vlclting retraction based safety rh in;~ These r-~hi~ni require that a center rod be retracted a predet~n; nl~ minimal distance before the apparatus can be fired. The shaft of the insertion device is lal;r ~ nl~d and configured such that the head 30 of the insertion device will contact the fastener cartridge at the distal end of the apparatus prior to retraction sufficient for firing.
In another preferred i -a;r~nt of the insertion device, the anvilless head is provided with 35 :,LluL:Lur ~ to protect and retain staples contained within staple pockets of a surgical stapler. The structure can include projections, preferably arranged in C~ C~ LiC
rings, each of which extend into a corr.oqr~n~; n~ staple pocket of the surgical stapler to protect and retain the staple therein. Preferably, the shaft is provided with 5 alignment structure in the form of a plurality of longitudinal ribs. The ribs engage c~LL-~l,J .l;n~
structure on the surgical tissue fastening apparatus and ensures proper ~ ; L of each of the proj ections within a corresponding staple pocket. Additionally, a 10 circumferential flange can be provided that extends proximally from the head to overlap the distal end of the surgical tissue fastening apparatus thereby further shielding the staple cartridge.
In another preferred embodiment, the anvilless insertion device can have one or more recesses disposed therein to reduce weight and help prevent undesired suction effects.: -BRIEF l~S~ OF T~E DR~WINGS

nR'r~TTRr ~E~ OF ~K~ r~M~
Referring now to FIGS. 1-3, and initially to FIGS. 1 and 2, there is shown an insertion device 10 for 3 0 use with surgical tissue fastening apparatus such as those disclosed in, for example, U.S. Patent Nos.
5,005,749 and 5,119,983, the entire disclosures of which are incorporated by reference herein. nhile the following discussion of the various ~ - ts of the insertion device is given with respect to a circular surgical stapler in general and, in particular, an anastomosis surgical stapling inDL~, -nt such as that di6closed in U.S. Patent No. 5,005,749, it will be noted that the insertion device is equally applicable for use with multipart surgical fastening devices such as a fragmentable anastomosis ring applier disclosed in U. S .
Patent No. 5,376,098 or the like. As used herein the term "distal" refers to that part of the device, or c _ r~nont thereof, furthest ~rom the user, while the term "proximal" refers to that part of the device, or ~ -n,~nt thereof, closer to the user.
Insertion device 10 is ,1~; gn ~d to provide a smooth leading surface for trans-anal insertion of the surgical tissue fastening apparatus and generally includes head 12 and a shaft 14 extending proximally therefrom. ~ead 12 is monolithically formed and has a smooth atraumatic leading or outer surface 16.
Preferably, head 12 has a rounded distal end 18 and relatively rounded off proximal end 20 adjacent shaft 14.
Both head 12 and shaft 14 are preferably fabricated from a biocompatible material.
A head extension 22 is preferably provided int~ te proximal end 20 and shaft 14 to provide a smooth transition therebetween. It should be noted that both head 12 and head extension 22 are anvilless, that is, devoid of any staple ~1 ;n-h;n~ structure such as, for example, a ring of staple r,l ;n~-h;n~ buckets. Shaft 14 generally includes a shaft barrel 24, a distal end 26 of which is inserted and affixed within a bore of head 12 and/or head extension 22. Alternatively, shaft 14 and head 12 can be integrally formed or molded. Shaft 14 preferably includes a conical tip 28 formed on a proximal end 30 of shaft barrel 24. Alternatively, the shaft can be hollow as discussed in greater detail with respect to Fig. 12.
In order to facilitate attachment of insertion device 10 to a surg ~cal tissue fastenins apparatus, att~hl nt structure, preferably in the form of a radial recess or groove 32, is formed in shaft barrel 24 at proximal end 30 thereof and adjacent conical tip 28.
Groove 32 is ~l;r--lc;~npd and configured for detachable elly~y -nt with corr~sr~nri; n~ retaining structure, such as that contained in a distal end of a center rod, provided in the surgical stapling in:,Ll, L (not shown).
As noted above, head 12 is preferably formed as a solid monolithic structure. Preferably head 12 has a maximum radius subst~n~;~lly equal to the maximum radius of a distal end of the surgical stapling in,L, ~.
Head 12 can be formed by various methods, such as, injection molding of a suitable biocompatible plastic, for example. Additionally, shaft 14 can be molded integrally with head 10 or can be formed as a separate structure .
When shaft 14 is formed separately, it is preferably formed of stainless steel or plastic. Head 12 and shaft 14 can be assembled by inserting distal end 26 of shaft 14 in a bore of head 12 and/or head extension 22. Shaft 14 can be secured to head 12 and/or head extension by various means, such as, for example, a threaded interconnection or securing distal end 2 6 within the bore by means of a suitable adhesive.
As noted above, insertion device 10 is particularly ~ n-~cl for use with surgical tissue fastening apparatus employing a retraction ~r~n~lent safety ~ ;~m, such as, for example, the anastomosis surgical stapling ill~LL~ -nt disclosed in U.S. Patent No.
5,005,749 and 5,119,983. A retraction ~r~n~l~nt safety r~ n;~-m disables or blocks activation of the stapling in~ L until such time as a center rod, having a staple ~!l ;nl-h;n~ anvil affixed thereto, has been retracted to within a minimal pre~pt~rm;n~d distance from the staple cartridge disposed at the distal end of the stapling in:,Ll L. This prf~det~rm;n~d distance ensures CA 02202736 1997-04-1~
_ g that the sp~r.;f;r size staple will completely penetrate the tissue sections to be fastened and will be properly crimped by the staple ~l ;n-~h;n~ buckets of the anvil thereby preventing incomplete stapling of the tissue 5 sections. Thus, it is the center rod that must move the pr~d~t~rm;n~cl minimal distance before the safety r-~h~n; Fm is disabled.
The disclosed insertion devices and, in particular, insertion device 10 prevents firing when 10 installed on the stapling in~ L, L. Referring now to FIG. 3, this is ~ h~ by configuring and ~i---nRi~n;ng the length "L" of shaft 14 so that the center rod cannot be retracted to within the predet~rm;n~d minimal distance re~auired for firing.
15 Preferably, head 12 and/or head extension 22 abut a distal end of the surgical stapling in~L, -nt before the predet~rm;n~ minimal distance is achieved. Thus the surgical stapling in~LL, --,t cannot be activated while insertion device 10 is installed thereon.
Referring to FIG. 4, there is shown an anastomosis surgical stapling in~l L, ~ such as that disclosed in U.S. Patent No. 5,005,749. The in~LL, I
100 includes a yoke 102, a pusher tube assembly 104 which extends from the yoke 102 to carry a staple assembly 106 25 at the distal end, an anvil assembly lOg at the distal end of the instrument and an actuating r-~h~n;~m which extends from the anvil assembly 108 through the pusher tube assembly 104 to a wing nut 110 at the proximal end of the in~l_L, I for moving the anvil assem~bly 108 30 relative to the pusher tube assembly 106. In addition, a pair of handles 112 are pivotally mounted on the yoke 102. ~andles 112 are mounted so as to be manually grasped by a surgeon and moved towards each other, as indicated by the arrows in order to fire the staples (not shown) 35 from the staple assembly 106 towards the anvil assembly 108. A safety lock 114 is also mounted on the proximal CA 02202736 1997-04-1~
end of the yoke 102. Safety lock 114 is blocked from rotating out of the way of handles 112 until a center rod has been retracted a predet-ormin~od minimal distance in the manner disclosed in 13.S. Patent ~o. 5,005,749.
Referring now to FIGS. 5-8, and initially to FIGS. 5 and 6, there is shown an alternate embodiment of an insertion device which, in addition to performing the activation prevention and dl_Lallllldl_iC insertion functions described hereinabove with respect to insertion device 10, is particularly configured to protect and secure staples located in staple pockets of the surgical stapling instrument during insertion of the surgical stapling in~l L- I_ into and through a body cavity, such as, the rectal stump. Insertion device 34 is similar to insertion device 10 and generally includes a substantially monolithically formed head 36, devoid of staple ~-l inr~h;ng structure, and a shaft 38 ~rt~on~ing from head 3 6 .
Shaft 38 is similar to shaft 14 described above and includes a shaft barrel .40 preferably having a conical tip 42 at a proximal end 44 thereof. Attachment structure in the form of a radial recegs or groove 46 ig formed in the proximal end 44 of shaft barrel 40 to facilitate detachable engagement of insertion device 34 with a suitable surgical tissue fastening device in the manner described hereinabove with respect to insertion device 10. A distal end 48 of shaft 38 is affixed within head 36, or integrally molded therewith, in the manner described hereinabove with respect to insertion device 10.
Insertion device 34 is specifically configured to protect and retain staples within staple pockets of a surgical stapler during insertion of the stapler into and through a body cavity. Thus, as best shown in FIGS. 6 and 8, head 36 includes a plurality of proximally facing projections 50 extending from a proximal face 52 of head CA 02202736 1997-04-1~
36. Preferably, projections 50 are arranged in two staggered and concentric rings such as, for example, inner and outer rings 54 and 56, respectively.
Inner and outer rings 54 and 56 are arranged so 5 as to position a single projection 50 within a single staple containing pocket of a surgical stapling ina~L, L upon retraction of insertion device 34 adj acent the staple cartridge at the distal end of a stapling in~L -nt as will be described in more detail 10 below.
Head 36 also ;n~ tlec a circumferential and proximally extending flange 58 which is configured to overlap an outer edge of the distal end of an associated surgical stapling in .LL, -~t. Flange 58 inhibits debris 15 and fluids from entering the space between insertion device 34 and the distal end of the stapling ina~L~ L
and also provides for a smooth transition between the insertion device and stapler.
Referring to FIGS. 5 and 6, in order to aid in 20 Al ign;n~ projections 50 with cuLLe~ ullding staple pockets, shaft 38 includes alignment structure in the form of an ~l ;,j L sleeve 60 having a plurality of circumferentially spaced ribs 62. Sleeve 60 may be formed integrally with shaft 38 or separately, and secured to 25 shaft 38 by a suitable medical grade adhesive. Ribs 62 are configured to engage cOLL~L. ,-lin~ Al; j L
structure within a surgical stapler and thus ensure correct Al i 3 -nt of projections 50 with corresponding individual staple pockets upon retraction. Similar 30 alignment structure is disclosed in U.S. Patent No.
5,119,983.
Shaft 38 is preferably also provided with a high friction or knurled portion 64 to facilitate grasping insertion device 34 using known surgical 35 grasping inDLLI Lcltion and techniques.
CA 02202736 1997-04-1~
-- lZ --Referring now to FIG. 7, insertion device 34 is illustrated partially installed in a aistal end 66 of a surgical stapling inDLl, L 68. Surgical stapling instrument 68 includes a plurality of circumferentially spaced staple pockets 70 in distal end 66 thereof. Prior to stapling a tissue section, each staple pocket 70 contains a generally IJ-shaped staple 72 which, when driven out of staple pockets 70, through tissue sections and into a staple clinching anvil member, securely fastens tissue sections together. As shown, an inner surface 74 of flange 58 is dimensioned and configured to overlap an outer circumferential surface of distal end 66. ~hus projections 50, in combination with flange 58, protect and retain staples 72 contained within the surgical stapling in=.~L, L 68 when insertion device 34 is retracted adj acent to distal end 66 of stapling inDLL r~t 68 .
Referring now to FIGS. 9-11, and initially to FIG. 9, t_ere is shown another preferred embodiment of an insertion aevice. Insertion device 76 performs the actuation prevention and dLLdUllld~iC insertion functions described hereinabove with respect to insertion device 10 and generally includes a head 78, also devoid of staple rl 7nrhin~ structure, and a sha~t 80 integral with and extending proximally from head 78. Head 78 and shaft 80 are preferably monolithically formed of a suitable material, such as, for example, plastic. IIead 78 has a smooth, conical aLLdul,ldLic leading outer surface 82, while shaft 80 includes at~rht ~ structure, preferably in the form of a radial recess or circumferential groove 84, at a distal qnd 86 thereof. ~
Referring now to FIGS. 10 and 11, head 78 has a substantially flat proximally facing surfacq 88 oriented substantially perp~n~ i r~ r to a longitudinal axis of shaft 80. Preferably, head 78 is provided with a plurality of recesses or bores 90 extending from surface CA 02202736 1997-04-1~
-88 partially into head 78. Bores 90 serve to reduce the weight of insertion device 76 as well as reduce suction effects existing between tissue and a surgical tissue fastening device as insertion device 76 is extended and 5 retracted with respect thereto.
Similar to that of insertion device 10, shaft 80 of insertion device 76 is dimensioned and configured to be insertable in the distal end of a surgical stapling in~L, ~. The length "~1" of shaft 80 is also 10 ~l; r ~ n~-d and conf igured such that it prevents deactivation of a safety -hAn;~m when the proximal surface of head 78 is adjacent the distal end of the surgical stapling instrument.
With reference to Fig. 12, an alternate 15 preferred ' _ ';1- ~ of an insertion device is shown.
Insertion device 100 is similar to the previous embodiments, however, shaft 106 ~Y~n~l;n~ from atraumatic head 102 is a hollow structure adapted to receive a solid rod 110 extending from a surgical stapling in~ nt 20 (not shown). In this ' _~;r-nt~ the insertion device is secured to the stapling apparatus by inserting solid shaft 110 into hollow shaft 106. Solid shaft 110 preferably has circumferential recess 112 which is adapted to engage locking structure associated with the 25 insertion device shaft. Similar shaft connecting structures are disclosed, for example, in U.S. Patent No.
5,205,459 and can be applied to each previous embodiment disclosed herein. Returning to Fig. 12, the insertion device preferably has a smooth surface 104 devoid of 30 stapling forming pockets and shaft 106 has optional ~1;,; ~ structure 108. As previously described, shaft 106 can be fabricated to have a length sufficient to prevent disengagement of a lockout member which requires a predet ~rm;nprl longitudinal displ ~ ~ within the 35 stapling apparatus.
It will be understood that various modifications can be made to the o~horl; nts disclosed herein. For example, as noted hereinabove, the disclosed : ' 'ir- Ls are suitable for use with various surgical 5 tissue fastening in~,~L L:, and thus the specific att~ structure can be varied to ~cc -'-te the same. Additionally, the various '~O~l;T ~5 need not prevent activation of tissue fastening apparatus but can be dimensioned and configured to provide ease of 10 insertion only. Therefore, the above description should not be construed as limiting, but merely as ~ 1;f;cations of preferred -~; r ~-lt. q~hose skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
