Abstract
Viscerotomy closure devices and methods of use close a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure. A mesh with a hole in its center and an attached loop of suture having a Roeder knot is mounted on the protruding rod of an end-to-end anastomosis stapler between the anvil and the staple carrying member. The mesh covers the staple receiving slots. When rotated when in contact with tissue, an augur-shaped blade attached to the anvil's exterior self-feeds the tissue through a notch in the anvil's base into the space between the anvil and the staple carrying member. After the stapler is fired to staple the mesh to the tissue and create a viscerotomy, a knot pusher cinches the loop of suture and subsequently tightens the Roeder knot to maintain the cinch.
Description
- The present patent document is a continuation of application Ser. No. 12/152,329, filed May 14, 2008, which claims the benefit of the filing date under 35 U.S.C. §119(e) of Provisional U.S. Patent Application Ser. Nos. 61/001,427 filed Nov. 1, 2007 and 60/930,284 filed May 15, 2007. All of the foregoing applications are hereby incorporated by reference.
- The present invention relates to a viscerotomy closure device and method of use for use in connection with closing a hole created during surgery. The viscerotomy closure device and method of use has particular utility in connection with closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure.
- Viscerotomy closure devices and methods of use are desirable for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure. At the inception of transgastric surgery, a gastrotomy is created by using a hollow needle to place a hole in a patient's stomach through the patient's skin. The gastrotomy must be closed at the completion of the procedure. Conventional methods for creating and closing the gastrotomy are time consuming and increase the possibility of undesirable reopening of the gastrotomy.
- The use of circular stapler tissue retention spring methods is known in the prior art. For example, U.S. Pat. No. 5,309,927 to Welch discloses a circular stapler tissue retention spring method. However, the Welch '927 patent does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and has further drawbacks of lacking an augur-shaped blade.
- U.S. Pat. No. 7,182,239 to Myers discloses a segmented introducer device for a circular surgical stapler that is capable of fitting onto the center rods of circular stapling devices having different stapler head diameters. However, the Myers '239 patent does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and additionally does not have an augur-shaped blade.
- Similarly, U.S. Pat. No. 5,197,648 to Gingold discloses a surgical stapling apparatus that joins hollow tubular organs. However, the Gingold '648 patent does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and cannot does not have an augur-shaped blade.
- In addition, U.S. Pat. No. 5,261,920 to Main et al. discloses an anvil bushing for circular stapler that is for use with a surgical circular stapler. However, the Main et al. '920 patent does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and also does not have an augur-shaped blade.
- Furthermore, U.S. Pat. No. 5,104,025 to Main et al. discloses an intraluminal anastomotic surgical stapler with detached anvil that is a surgical stapling mechanism. However, the Main et al. '025 patent does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and further lacks an auger-shaped blade.
- United States Patent Application Publication Number 2007/0021759 to Griffith et al. discloses a flexible endoscopic anastomotic ring applier device that deploys an anastomotic ring device. However, the Griffith et al. 2007/0021759 patent application publication does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and has the additional deficiency of lacking an auger-shaped blade.
- In addition, United States Patent Application Publication Number 2005/0228414 to Clanton et al. discloses an apparatus and method of use of a circular surgical stapler that removes a circumferential portion of a hollow body organ from a patient. However, the Clanton et al. 2005/0228414 patent application publication does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and also does not have an augur-shaped blade.

FIG. 1 , a new and improved viscerotomy closure device and method ofuse 10 of the present invention for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure is illustrated and will be described. More particularly, the viscerotomy closure device and method ofuse 10 has a loop ofsuture 12 with aRoeder knot 14 attached to acircular mesh 16. The loop ofsuture 12 may be attached to themesh 16 by weaving it through or suturing it into themesh 16. Themesh 16 has ahole 44 in its center. In the current embodiment, the loop ofsuture 12 andmesh 16 have arod 24 inserted through their centers so they can be placed on the end of thestaple carrying member 20 of an end-to-end anastomosis stapler 18. Alternatively, the loop ofsuture 12 andmesh 16 can be placed on the anvil 28 (shown inFIGS. 3-5 ) of the end-to-end anastomosis stapler 18. In addition, multiple instances of the loop ofsuture 12 andmesh 16 can be used so that a loop ofsuture 12 andmesh 16 is on both thestaple carrying member 20 and theanvil 28. The loop ofsuture 12 is connected to aknot pusher 42, which will be described in more detail in the discussion ofFIG. 7 . Thestaple carrying member 20 hasstaple receiving slots 22 in the end covered by the loop ofsuture 12 andmesh 16. In the current embodiment, loop ofsuture 12 andmesh 16 are made of polyglactin 910, an absorbable suture material. Moving on toFIG. 2 , a new and improved viscerotomy closure device and method ofuse 10 of the present invention for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure is illustrated and will be described. More particularly, the viscerotomy closure device and method ofuse 10 has a loop ofsuture 12 with aRoeder knot 14 woven through amesh 16. The loop ofsuture 12 andmesh 16 are placed over thestaple receiving slots 22 of thestaple carrying member 20 of an end-to-end anastomosis stapler 18.Rod 24 protrudes through thehole 44 in the center ofmesh 16.Staples 26 are visible withinstaple receiving slots 22.Staples 26 are non-absorbable titanium staples in the current invention, but absorbable staples could also be used. - Continuing with
FIG. 3 , a new and improved viscerotomy closure device and method ofuse 10 of the present invention for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure is illustrated and will be described. More particularly, the viscerotomy closure device and method ofuse 10 has ananvil 28 with one end attached to the end ofrod 24.Anvil 28 is generally conical in shape and has an augur-shapedblade 30 that starts at itstip 46 and twists around to end at itsbase 48 below the level of theanvil 28.Blade 30 directs anytissue 38 it comes into contact with downward, causing thetissue 38 to become engaged between thestaple carrying member 20 and theanvil 28 simply by pushing theanvil 28 against thetissue 38 and rotating the end-to-end anastomosis stapler 18 360° about its axis. Thebase 48 ofanvil 28 has anotch 32 so the final twist of theblade 30 enables the stretchedtissue 38 defect it creates to not be greater than the inner diameter of the staple line defined by thestaple receiving slots 22. Additionally, a conical spacer can be used below theanvil 28 to ensure that when the end-to-end anastomosis stapler 18 is fired, thestaples 26 engage with the entire circumference of thetissue 38. InFIG. 4 , a new and improved viscerotomy closure device and method ofuse 10 of the present invention for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure is illustrated and will be described. More particularly, the viscerotomy closure device and method ofuse 10 has ananvil 32 withstaple clinching grooves 34 in itsbase 48.Staple clinching grooves 34 are aligned withstaple receiving slots 22 so that the ends ofstaples 26 are clinched bystaple clinching grooves 34 when the end-to-end anastomosis stapler 18 is fired. - Furthermore, in
FIG. 5 , a new and improved viscerotomy closure device and method ofuse 10 of the present invention for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure is illustrated and will be described. More particularly, the viscerotomy closure device and method ofuse 10 is depicted in use withblade 30 ofanvil 28 in contact with thetissue 38 of anorgan 36. As the blade is rotated 180°, thetissue 38 self-loads into the space between theanvil 28 andstaple carrying member 20 because of the augur-shapedblade 30. - In
FIG. 6 , a new and improved viscerotomy closure device and method ofuse 10 of the present invention for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure is illustrated and will be described. More particularly, the viscerotomy closure device and method ofuse 10 is depicted in use subsequent to the firing of end-to-end anastomosis stapler 18. The end-to-end anastomosis stapler 18 has created aviscerotomy 40 intissue 38 oforgan 36 and circumferentially secured the loop ofsuture 12 andmesh 16 at the margins of theviscerotomy 40 withstaples 26. The end-to-end anastomosis stapler 18 has also cut the center ofmesh 16 so thehole 44 in the center ofmesh 16 is aligned with the outer edge of theviscerotomy 40. - Moving on to
FIG. 7 , a new and improved viscerotomy closure device and method ofuse 10 of the present invention for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure is illustrated and will be described. More particularly, the viscerotomy closure device and method ofuse 10 is shown in use subsequent to the firing of end-to-end anastomosis stapler 18.Staples 26secure mesh 16 and loop ofsuture 12 around the exterior ofviscerotomy 40.Knot pusher 42 is used to cinch down the loop ofsuture 12, thereby tightly closing theviscerotomy 40. TheRoeder knot 14 is then tightened to maintain the cinch in the current embodiment. Alternatively, extracorporeal knots can be placed using theknot pusher 42, or some other locking device can be employed. - Concluding with
FIG. 8 , a new and improved viscerotomy closure device and method ofuse 10 of the present invention for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure is illustrated and will be described. More particularly, the viscerotomy closure device and method ofuse 10 is depicted in use with the loop ofsuture 12 cinched down and secured by theRoeder knot 14. The portion of loop ofsuture 12 connected to theknot pusher 42 has been cut off, and theknot pusher 42 has been removed. The cinched loop ofsuture 12 has tightly closed theviscerotomy 14 intissue 38 oforgan 36. - In use, it can now be understood that a loop of suture with a Roeder knot and a connected knot pusher is attached to a mesh with a hole in its center. The protruding rod of an end-to-end anastomosis stapler is inserted through the hole in the mesh's center so that the mesh and loop of suture cover the staple receiving slots of the end-to-end anastomosis stapler's staple carrying member. The base of an anvil is then attached to the end of the protruding rod. A viscerotomy is created by passing a hollow needle through a patient's skin into a patient's bodily organ. One end of a wire is advanced through the hollow needle into the bodily organ. This end of the wire is then pulled through the patient's mouth and attached to the tip of the anvil. The tip of the anvil is brought into contact with tissue by pulling on the other end of the wire. The augur-shaped blade mounted on the anvil is rotated by the end-to-end anastomosis stapler, which feeds the tissue into the space between the anvil and the staple carrying member. Use of the hollow needle and wire ensures there is a safe point on the bodily organ to pass the anvil through and maintains the tissue in tension against the augur-shaped blade while the anvil is rotated by the end-to-end anastomosis stapler. When the tissue is in position, the end-to-end anastomosis stapler is fired. The staples are ejected from the staple receiving slots in the staple carrying member and pass through the mesh and the tissue prior to having their ends clinched by staple clinching grooves in the anvil's base. The stapled mesh secures the loop of suture to the tissue around the resulting viscerotomy. The end-to-end anastomosis stapler and the wire are then removed from the patient. The knot pusher is used to cinch down the loop of suture and tighten the Roeder knot to tightly close the viscerotomy. The portion of the loop of suture connected to the knot pusher is then severed from the portion of the loop of suture connected to the mesh, and the knot pusher and the severed portion of the loop of suture are removed.
- While a current embodiment of the viscerotomy closure device and method of use has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. For example, any suitable absorbable or non-absorbable suture material may be used instead of the polyglactin 910 described. Also, the non-absorbable titanium staples may be replaced by absorbable staples. Furthermore, the orientation of the circular staples could be changed to make them deploy perpendicularly to the route of the loop of suture, or the loop of suture could be placed in a zigzag pattern over the staple receiving slots so the loop of suture will be entrapped by the staples, thereby eliminating the use of mesh. And although closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure has been described, it should be appreciated that the viscerotomy closure device and method of use herein described is also suitable for closing a gastrotomy or defect to any hollow viscus, e.g. colon, vagina, or intestine. Furthermore, a wide variety of locking devices, such as a clip, may be used instead of the Roeder knot described.
- Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
- The foregoing description of various embodiments of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Numerous modifications or variations are possible in light of the above teachings. The embodiments discussed were chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally, and equitably entitled.
