Description

(54) MACHINE FOR LAYING CIRCULAR

I

The invention relates to medical technology and is intended to anastomose the rectum and colon.

A device for applying circular anastomoses to hollow organs, such as guts, comprising a tubular body, a head rigidly mounted on a rod, in whose groove plastic washers, a pusher, a cylindrical knife, a driving mechanism of the rod and a pushing mechanism consisting of a movable and stationary handle, is known. current The bowels are stapled with metal clips, and the staple suture requires manual stitching of the second floor, which is technically difficult to remove when a large part of the rectum is removed. 11.

The purpose of the invention is to connect the walls of the intestines without placing staples and ligature seams.

The goal is achieved by the fact that in the apparatus on a tubular body there is an anchor to the gaps in the hollow organs.

Lena mandrel, on which the connecting ring is removably mounted, in which a crown with needles is placed, and shock absorbers, located on the needles, and on the head a second connecting ring, made with a locking lug, is located on the head.

The needles have locking grooves.

The connecting rings have chamfers on the outer edges facing

to one to the other.

FIG. t shows an apparatus for applying circular anastomoses to hollow organs, general view, incision; Fig. 2 shows the connecting rings of the apparatus before connecting them; Fig. 3 is the same, after joining the intestines.

Claims (3)

The device contains a tubular body 1, a rod 2 with a rigidly fixed head 3 and a drive 4, a cylindrical knife 5, a plastic washer 6 and a connecting rings drive consisting of a movable and fixed handle 7 and 8. The mandrel 9 is fixed on the tubular body 39 I which is removably mounted connecting ring 10, in which is placed the crown II with needles 12, and shock absorbers13, located on the needles. On the head 3 a second connecting ring 1 is removably arranged, made with a locking lug 15. The needles 12 have locking grooves 16, and the connecting rings have chamfers 17 on the outer edges. The device works as follows. After the diseased part of the rectum is removed by the pathological process, the apparatus is inserted through the anal opening into the rectal stump. By means of the nut 18, the connecting rings 10 and I are diluted to a distance convenient for further work. On the rectal stump, catgut purse suture is put in place before touching the pipe 19. The connecting ring 1 is inserted into the lumen of the large intestine, then the purse string is put in advance in front of the colon. With the aid of the nut 18, the coupling rings tO and H with the guts fastened on them come together. By pressing the handle 7, the final mechanical connection of the rectum and large intestine is made, the movable crown 11 with the needles 12 finally fixing the connecting rings 10 and 14, the cylindrical knife 5 cutting off the suture pads and excess intestinal walls. Using a screwdriver, the rod 9 releases the connecting ring H and the apparatus is removed from the anus. The connecting rings 10-I, the movable crown with needles and shock absorbers 13 remain in the rectum until it fully grows together with the large intestine (7-8 days), after which it self-exits the intestine together with the feces. I After the accretion of the intestinal walls and the rejection of the connecting rings in the anastomosis area does not leave any foreign bodies, which drastically reduces the risk of the development of cicatricial narrowing of the anastomosis. Claim 1. An apparatus for applying circular anastomoses to hollow organs, such as the rectum, comprising a tubular body, a stem with a rigidly fixed head and a drive, a cylindrical knife, a plastic washer and a connecting ring drive consisting of a movable and fixed handle, characterized by that, in order to connect the walls of the intestines without placing staples and ligature seams, a mandrel is fixed on the tubular body, on which is attached a connecting ring, in which a crown with needles is placed, and shock absorbers, asggolozhennye on the needles and on the head is removably disposed a coupling ring formed with the locking projections. 2. The device according to claim 1, about tl and h ayusch and the fact that the needles have locking grooves .. 3. The apparatus according to claim 1, characterized in that the connecting rings have chamfers on the outer edges facing one another.
