Description

The invention relates to medicine, in particular to surgical apparatus for imposing anatomosis on the hollow organs, advantageously of the digestive tract.

A surgical apparatus for forming anastomoses in the digestive tract is known, comprising a flexible tubular body with a head, a flexible rod located in the tubular body, a stop head, a knife with a pusher and a drive with a pusher 1.

The known device is difficult, when using it, the sufficiently rapid adhesion of the walls of the hollow organ after the application of the anastomosis is not achieved.

The purpose of the invention is to reduce the time to accretion of the walls of the hollow organ after the application of the anastomosis and to simplify the design of the device.

The goal is achieved by the fact that in a device comprising a flexible tubular body with a head, a flexible rod located in a tubular body, a stop head, a knife with a pusher and a knife drive with a pusher, a knife with a pusher are installed in the stop head power lock.

In addition, the power lock is made in the form of a shear pin.

FIG. 1 shows the working part of a surgical apparatus for forming anastomoses in the digestive tract, a longitudinal section; in fig. 2 - knife drive with pusher.

A surgical apparatus for forming anastomoses on a pinned tract includes a flexible tubular body 1 with a head 2, a flexible rod 3 located in the tubular body 1, a stop head 4, a knife 5 with a pusher 6 and a drive 7 of the knife 5 with a pusher 6.

A knife 5 with a pusher. M. 6 is installed in a stop head 4 and is connected with it by means of a power lock 8, made in the form of a shear pin.

On the flexible rod 3 is installed the tip 9, which is located in the nest of the pusher 6 and fixed by the cap 10.

A screw 11 is fastened to the end of the flexible rod 3 opposite to the tip 9. The drive 7 of the knife 5 with the pusher 6 is made in the form of a lamb nut mounted on the stop 12 and located in a threaded joint with a screw 11.

The stop 12 is mounted on a flexible tubular.m case 1.

The pusher 6, flexibly. The tubular body 1 has holes 13 and 14, and the stop 12 has a radial groove 15 for the passage of gases.

Case 1 is reinforced from the inside with a flexible meta: 1 face shell 16.

The knife 5 is connected to the pusher 6 by means of a screw 17. In 1T), Dexter 2, a partial gasket 18 is installed to cut the fabric.

On the head 2 there is a tube 19.

The device works as follows

After resection of the site of the pike into the lumen of the formation of the ends through, the apparatus is fed into the colostrum, then the apparatus is moved apart, i.e. the head 2 is left at one end of the intestine, and the stop head 4 with the pusher 6 is at the other end of the intestine, while the pusher is partially located on the tube 19 of the head 2. The loose ends of the intestine on the tube 19 are tightly sutured. After that, the stop head 4 is brought closer to the drive 7. As soon as the two K9Nts are pressed to each other with a certain force, the rotation of the wing nut is stopped. The surgeon performs the 1a, manual extension of the circular anastomosis. The gas from the bottom of the pick is discharged through the holes 13 and 14, the tubular body 1 and the radial groove 15 to the atmosphere, the tube 14, the gaps between the tip 9 and the cable .5, the rod 11 and the stop 12, the grooves to the outside, to the atmosphere.

After applying an anastomosis and careful testing of its quality, the surgeon again begins to rotate the wing nut 7, the flexible rod 3 begins to pull more strongly, and the tension force is transmitted through the packer 9, the pusher 6. the knife .5 pas 1 PTIF 8 to the stor} enclosures i. With further tension of the cable, the plift 8 is in place of the interface between the knife and the thrust. v; rHOvenio is cut off, 1K) G 5 rushes toward body 1, a double-breasted dress of the intestinal tissue occurs. Bi) ipy6.4eHHbie the intestinal walls remain n and; .1stp A.

After cutting, the thrust holongh is moved away from the hull, then the apparatus .1detends from the SPNITO NIN evarite.1nogo through
