Abstract

The invention relates to medical technology, namely to surgical stapling apparatus. The aim of the invention is to reduce the inconsistency, improve the quality of the seams and reduce the trauma of stitched fabrics. The tool contains pivotally connected branches 1 and 2, one of which (branch 2) has a curved channel 3 under the wire 4, a sponge 5 with a matrix 6 for forming a stitch, a wire feed mechanism and a knife 8 for cutting the wire, kinematically connected with the feed mechanism . On the branch 2 with a curved channel, an additional matrix 9 is made, located between the output 10 of the curved channel and its end 11. The tool operates as follows. When the branches 1 and 2 are collapsed, the wire 4 is fed to the matrix 6, piercing the fabric, then, rounding the matrix 6 and again puncturing the fabric, is formed in the matrix 9 in an O-shape. 2 Il.

The invention relates to medical technology, namely to surgical stapling apparatus.

The aim of the invention is to reduce the inconsistency, improve the quality of the seams and reduce the trauma of stitched fabrics.

FIG. 1 shows an instrument, a general view; in fig. 2 - working part of the tool, section.

The tool contains pivotally connected branches 1 and 2, on one of which (branch 2) there is a curved channel 3 under the wire 4, a sponge 5 with a matrix 6 for forming stitch 7, a wire guiding mechanism, a knife 8 for cutting the wire, kinematically associated with the feed mechanism. On the branch with a curved channel, an additional matrix 9 is made, located between the output 10 of the curved channel and its end face 11.

With the tool work as follows.

The staple wire is introduced into the channel before it appears from the exit in the tool working area. The disclosed matrices are superimposed on the suture areas prepared for stitching and the surgeon brings together the branding I and 2 together. In this case, the wire feed mechanism feeds the wire to the die 6. At the same time, the die closes and the blade 8 moves forward. The feed wire, the exit from the channel, enters the upper matrix, slides along the surface of the forming recess, forming a semiring. The exit from the top of the matrix, the end of the wire pierces the connected

tissue and enters the forming recess of the lower matrix, where the remaining part of the bracket is also formed in the form of a half ring. By the time of the formation of a hollow ring of cutting, the edge of the knife 8 fits to the formed bracket, cuts it off and makes its upper edge before forming a closed ring. In the subsequent abduction of the battle, the component parts of the instrument are brought to their original position. The cycle is repeated when the branches are fully brought together and the next bracket is set.

The tool allows you to form O-brackets of the correct configuration, which improves the quality of the seam. Such a configuration of staples reduces tissue injury during stitching, which indirectly reduces the number of postoperative complications, and also improves the trophism of stitched tissues.
