Description

The invention relates to medical technology, and names to surgical instruments for stapling seams on various organs and soft tissues.

A known tool for applying 11JBOB staples, which contains articulated joints with the stop and pressure jaws, the push rod of a rifle with a grooved protrusion and the knife 1.

However, the known tool has a complex structure, which reduces its performance and reliability. In particular, the spring-toothed drive of the upper jaw and the knife from the upper jaw triggers over time, the force of the spring that returns the knife and the upper jaw to its initial position decreases.

11, the spruce of the invention is a simplified design of the tool.

This goal is achieved by the fact that the tool for applying I1JBOB brackets, an eder 1 as well as arpirno connected branches with a thrust and pressure sponges, a pusher of a drill with a corrugated protrusion on the knife, a pusher and a knife are made as one piece, at the free end of which is a corrugated ledge.

On fn1-. In Fig. 1, an instrument is shown for nal (zheny stapled seams, general view; in (f) Hi 2 is a section L-A in Fig. 1; in Fig. 3 - a node 1 in Fig. 1.

The tool for stapling joints contains pivotally connected branches 1 and 2 with support 3 and pressure 4 jaws, pusher) 5 lines with corrugated protrusion 6 and knife 7. Pusher 5 and knife 7 you: | о. 1nen as a single unit, the pusher D) being spabzhen with an elastic element 8, on the free end 9 of which the corrugated protrusion 6 is reinforced.

The tool works as follows.

In preparation for operation, through a hole in the elastic element 8, the wire is introduced into the channel 10 of the support sponge 3. The elastic element 8 is retracted and the wire is pushed until it passes through the opening of the support sponge 3, which channel 10 is pumped into. The tool is taken like scissors in a hand. In the initial position, the branches 1 and 2 are in the divorced position. At the same time, the rear end of the pusher 5 is fitted into the closed end of the longitudinal section 11. The working end of the pressing jaw 4 is fed under the branch 2.

During operation, the tool is oriented so that when closing the branches of the brimmed tissues are between the working ends of the jaws 3 and 4. Under the influence of the fingers or fingers, the jaws 1 and 2 begin to shrink, and the jaws 3 and 4 will first close and open between them stitched fabric. With further assembly of the branch, the elastic element 12 moves the pusher against the wire, 1oki, and the elastic element 8 with the reef ledge 6 outward. towards the working end of the tool. The elastic element 8 is of such a shape that, when, avizhenii t (x: 1katel 5 forward reef.
