Abstract
"CIRCULAR MECHANICAL ANASTOMOTIC GUN"
Abstract A mechanical gun for circular anastomosis of hollow organs by which the elements of a particular suturing device are engaged one into the other compressing between their walls the tissue edges of two resected hollow organs. The gun also comprises a circular cutting member which trims outside the compression area inside the device the edges of the compressed tissues, and then releases the circular mechanical gun from the suturing device which will be maintained until a natural suture forms between the connected hollow organs.

Description
- ``` ;: LZ9L9~
Back round of the Invention g The present invention is directed ~o a new mechanical gun suitable for performing circular anastomosis in hollow organs.
Circular mechanical guns are known in the art, and such guns utili~e for joining the tissue edges of the resected hollow organs a system of metalLic staples which are inserted from inside the hollow organ, into the overlapped tissues of the two hollow organ edges and are rivetted inwards to achieve the anastomosis.
Another known circular mechanical ~nastomotic gun includes a particular system consisting of partially metallic and partially plastic flat rings Xept together by a system of connecting nails with coaxial springs to achieve the anastomosis by compression applied to the tissue edges of the specific dissected hollow organs.
Summary of the Invention The circular mechanical anastomotic gun of the present invention achieves ~he anastomosis in the digestive system using a compression device which is the subject of a patent application filed by Applicants at even date with the present application.
This anastomosis device comprises three coaxial elements of ~ particular shape which reali~e the compression of the hollow organ dissected tissues between the walls of two of such elements, saia compression being applied suitably by inserting the third element into the second one.
After a certain period of time has elapsed, the 3~ compressed tissuas necroti~e and fall inside the hollow organ thereby disconnecting the device causing the compression from the organ~ Both are naturally eliminated w~ilst in that interval of time the anastomosis of the ~aced tissues immediately outside the area where the pressure is applied, occur~.

De~ailed Descrip~ion of the Invention In particular, a preferred embodiment of the invention consists of a circular mechanical anastomotic glln which will be illustrated in detail in Figs. 1 and 2 of the accompanying drawings. Such preferred gun however will not be considered limiting the ~cope of the invention.
The mechanical gun for circular anastomosis, forming the object of the present invention i6 essentially formed by three parts:
1) A head portion consisting of two parts: the first one, at one end, having a broad size, ~he second one having a cylindrical shape.
The broad part carries a device able to perform the anastomosis by compression, and a cutting member which allows the mechanical gun to disengage from the organs when the suturing is completed for assembly is realized, allowing the withdrawal of the same from inside the hollow organ. The cylindrical part is formed by a central pivot which is the axis of the whole circular mechanical anastomo~ic gun and makes it possible to introduce the gun end portion into the dissected hollow member. The central pivot is surrounded by a system of concentric tubular elements which support the outer and the intermediate element of the compression device; the median, the eiement of the compression device which i~ inserted into the ` intermediate element and lastly the inner one which supports the cutting me~ber. The last two tubular elements, i.e. the inner and the median ones, are operated ~y a differentiated motion allowing the cutting ~ember to continue its stroke even when the median cylindrical element carrying the compression device stops~

-- Brief Description of the ~rawings __ FIGUR~ 1 is a view of the gun shown in section taken along the device;
FIGURE 2 shows a detail of one end o~ the gun of FIGURE 1 in section, on an enlarged scale; and FIGU~E 3 shows a detail of the central portion of the gun of FIGURE 1 in section, on an enlarged scale.
Detailed Description -Figure 1 repre~ent~ the anastomotic gun in a rest position having in~erted the compression sut~ring device formed by the elements 1, 2 and 3, the last two being already connected. There is shown in the head portion, the central pivot 4 carrying the device 5 capable of ; stopping the element 3. The coaxial cylinder 6, inside of which the central pivot 4 extends. A thread connects the pivot 4 to the circular blade 7 which, when moved by operation of the median portion device contacts the element 3 and cuts it along the groove 8 therein prearranged to facilitate the cut. In this way, a port having a diaMeter bigger than that of the stop element 5 i~ defined 50 that the element 3 can slip through said port allowing the circular mechanical anastomotic gun to be disengagedO The elements 9 and 10 are connected by a threaded connection respectively to the tubular bodies 11 and 12, which are coaxial to the central pivot 4, and - carry the elements 2 and 1 respectively.
~; In the ~edian portion the lever arms 13 pivoted on the pivot 14, allow operation of the body 15, which i~
coaxial with the central pivot by transmitting movement to the circular blade 7 and to tha element 1. ~he spring~
16, when compressed in~ide the cylindrical holder~ 17, maintain ~he lever arms 13 in an open position whilst the ~; 35 spring 18 by means of the prong 19 operates ~he clevice safety gear.

~24~ 96 5.
In the end portion the centr~l pivot 4 i~
partially threaded so that rotation of thle knob 20 causes the locking nut 21 to 81ip against correspond;ng device parts.
A cap nut 22 is threadably attached to the very end of the threaded part of the central pivot 4. The cap nut 22 is shaped so that it can be viewed through the longitudinal slit 23, (detail in Fig. 1) on the circular member 24 provided with a scale 25 for evaluating the amount of central pivot 4 slip with respect to all the other parts of the mechanical anastomotic gun.
The head portion of the mechanical circular anastomotic gun of Fig. 1 may be modified as shown in details in enlarged scale, in Figure 2. The elements 39 and 40 carrying respectively the elements 3~ and 31 of the compression suturing device for effecting the anastomosis, show a diferent outline than the corresponding elements in Fig. 1, particularly the element 39 at the end opposite to the threaded portion whi~h was an annular reces~
delimited outwardly by a circular ledge 41 for the ~ngayement with a ~orresponding match~ng ledge of an element of a suitable suturing device.
; The mechanical anastomotic gun having the head portion as illustrated in Fig. 2, after the suturing device assembly has been moved forward and the operated tissue edges operated by means of blade 37 in connection with the groove 38 on the element 33, is separated from the assembled suturing device more easily than the gun of Fig. 1 and is e~sily pulled out of ~he hollow organ.
In use, th~ circular mechanical anastomotic gun according ~o the invention (reference is made in particular to the embodi~ent of Fig. 1, but obviou~ly operation is extended to the device modified as indicated in Fig. 2) i~ inserted through a suitable aperture into ~he hollow organ dissected and by a rotation of the knob 20, the element~ 2 and 3 are suitably spaced from each -49~96 other. The purse-string suture placed on the tissue edge of the dissected organ immediately above the member 2, is tightened, then the element 3 iB inserted inside the edge of the close hollow dissected organ the margins of which are stitched with another purse-s~ring sutuxe, and this suture i5 tightened on the central pivot 4, immediately below the element 3. With reversed operation of the knob 20, the elements 2 and 3 are positioned ~ne inserted into the other, then the arms of the mechanical anastomotic gun are operated to shift the element 1 and the circular blad~
7.
The element 1 and the circular blade 7 move together simultaneously until the element 1 reaches its .
final position fixing itself inside the element 2; then the circular blade 7 continues its movement and after having edged the purse-string sutures, it cuts the element 3 in connection with the groove 8.
: The circular mechanical anastomotic gun is then drawn out and the suturing devi~e remainS positioned inside the hollow organ, from which it will separate only when the necrosis of the tissues occurs which follows the ~ formation of a natural suture between the tissue edges :~ mating i~mediately out the area where the compression was : applied.
