ABSTRACT
A new purse-string instrument having arc shaped jaws and handles is described, by which it is possible to place mechanically, in surgery, purse-string sutures in very narrow and deep areas of the organism.
Description
~'~3~7 Background of the Invention The recent introduction in surgery of the mechanical circular s-taple devices which allow the mechanical placement of anastomoses, has made more frequen-t the requirement of purse-string sutures which are essential in order to suitably utilize said mechanical circular staplers.
Purse-string suture is a type of suture largely placed during surgical operations: its excution except when very narrow and deep areas is involved, is rather simple and quick -to be carried out.
Purse-string sutures can be placed manually or mechanically by means of traditional purse-string instrumen-ts which all are characterized by having both the two jaws - holding in between the tissue edges where it has -to be placed purse--string suture - and the two handles connecting jaw-holders and handle ringed ends, which extend rectilinearly.
Traditional purse-string instruments due to their straight form require for their utilization a space large enough so -that -they can be fitted end-to-end with -the strength of the straight needle when inserting the needle into the proper channel of the jaws.
However, should the purse-s-tring su-ture be placed in difficult technical conditions such as when it has to be placed on organs which lay deep in restric-ted sites, then traditional purse-s-tring instruments cannot be employed and consequen-tly, the purse-string su-ture may only be manually carried out, sometimes with grea-t difficulty, and -tha-t involves a considerable extension of the opera-ting time as well as a less certainty oE execution. Thus, in the diges-tive apparatus surgery, the placement of the purse--string suture, a procedure which is essential Eor a successful operation using mechanical circular staplers, may be effec-ted ~23~7 with the purse-string instruments of the art, easily and quickly at the level of the small intestine and colon, while the same suture at the level of the extraperitoneal rectum is practically impossible because the total encumbrance encompassing the jaws of the instrument and the straight needle which must be passed through the proper channel of the jaws is generally bigger than the space at disposal to carry out this maneuver.
Summary of the Invention It is the object of the invention to provide a new purse--string instrument having arc shaped jaws as well as arc shaped handles by which it is made possible the mechanical placement of purse-string sutures even in difficult technical conditions, i.e. narrow and deep operating sites.
Particularly the purse-string instrument of the invention, due to the particular shape of its jaws and handles, the latter extending between the jaw-holders and the two ring shaped ends, makes possible the mechanical placement of purse-string sutures even in very narrow and deep operating sites, e.g. at the level of the extra-peritoneal rectum, thus sharply reducing operation time and increasing the certainty of the execution.
Compared to the purse-string instruments having straight jaws and handles, the purse-string instrument of the invention although the lateral dimensions remain unchanged, allows a remarkable increase in the working surface o:F i-ts jaws.
A further advantage is gained by the purse-string instrument of the inven-tion, since due to the arc shaped handles it allows a perfect visibility of the operative field.
A fur-ther advantage of the purse-string instrumen-t of the invention is represented by the specially curved needle to be fitted end-to-end with the arc shaped jaws, by which ~23~7~7 it is possible to gain a grea-t reduction of lateral space occupied when inserting them in the proper channels of the arc-shaped jaws.
Detailed Description of a Preferred Embodimen-t The attached drawings are given as non-limiting example of a preferred embodiment of the purse-string instrument according to the present invention.
Figure 1 is a plan view from above of -the purse-string instrument showing the two coaxial arc shaped jaws 1 and

Detailed Description of a Preferred Embodimen-t The attached drawings are given as non-limiting example of a preferred embodiment of the purse-string instrument according to the present invention.
Figure 1 is a plan view from above of -the purse-string instrument showing the two coaxial arc shaped jaws 1 and
2, which fit together when the purse-string instrument is tightened up and the two intermediate segmen-ts 3 and -the handles 5 and 4 rigidly connected to the two segments
3 of which they are the continuation but extending curvili-nearly, hinged in 6 and having the two rings 8 and 7 at the opposite ends of the jaw 1 and 2 in respect to -the hinge 6. The arc shaped handles 5 and 4 carry each proximal-ly to the two ringed ends 7 and 8 notched side segments 9 & 10 suitable for mutual engagement to block the string-purse instrument in the required position.
Figure 2 is a left side view of the string-purse instru-ment of Fig. 1. There is exhibited a particular of construc-tion of the preferred embodiment, in which the two angles ~1 and ~2 are complementary angles. The angle ~1 is formed by the projec-tion of -the working surface of the jaws 1 and 2 matched and the longitudinal axis of the in-termediate segmen-ts 3; -the second angle ~2 is formed by the same longi-tudinal axis of the intermediate segments 3 and the tangent to -the arc shaped handles 4 and 5 at the end of -the segments 3. The different bend and length of handles 4 and 5 are also shown.
Figure 3 is a view o~ the ex-ternal jaw 2 from its hollow side, where are shown the par-ts 11 having smaller radius of curvature, which parts 11 all together form the working ~2367~
surface of the jaw 2 and are longitudinally grooved to provide a safe hold of the tissues and the channel 12 which crosses all the parts ~1 for the insertion of the curved needle.
Figure 4 represents a cross-section of the external jaw 2 where are shown the parts 11, the transversal recess J.3 having a U cross-section, the channel 12 and the bluntings 15 and 15' which provide a further reduction of the overall size of the purse-string instrument.
Figure 5 is a cross-section of the internal jaw 1 where are shown the parts 11', the transversal recesses 13' having a U cross-section, the channel 14 which crosses all the parts 11' for the insertion of the curved needle.
Figure 6 is a view of the jaw 1 from its convex side where are shown the parts 11' having bigger radius of cur-vature, which parts 11l all together form the working surface of the jaw 1 and are longitudinally grooved to provide a safe hold of the tissues and the channel 14 which crosses all the parts 11l for the insertion of the suitable needle.
Figure 7 is a perspective view of the purse-string instru-ment according to the previous figures.
In use the purse-string instrument of the invention is introduced into the site where the purse-string suture is to be placed; the edges of the tissues are stretched on the jaws which are then tightened together, the purse-string instrument blocked in the suitable position and the specially curved needle the radius of the curve of which adapts perfectly to the radius of the channel in the jaw/
is carefully passed through the proper channels of the jaws.
Tissues are then resected, the instrument is opened and the purse-string suture is perfectly placed.
