Abstract
Abstract A surgical instrument for stitching up tissues with lengths of suture wire, comprising a body made as a stem provided with a handle at one end and with a die at the other end for the lengths of suture wire to be bent. The die is shaped as a curved needle having a guide groove on its concave surface for a length of suture wire. The instrument incorporates also a magazine for the lengths of suture wire and a pushrod for driving the wire along the die guide groove. The pushrod has at its operative end a curved guide groove serving for final bending of the length of wire upon its coming off the die guide groove.

Claim 1
Independent Claim
157 words
A surgical instrument for stitching up tissues with lengths of suture wire, comprising: a body in the form of a stem; a handle provided at one end of said body and a die at the other end, said die having the form of a curved needle with a guide groove provided in an inner concave portion thereof and serving to push the lengths of wire therealong; a rotatable magazine for the lengths of wire, freely mounted on said body; a pushrod reciprocably mounted with respect to said body; and a projection of said pushrod having a flat portion for engaging a length of the wire, and a curved groove therein for the final bending of the length of wire after it has left said guide groove; said pushrod pushing out the length of the wire from said magazine during its movement toward said die, pushing it along said guide groove, and bending it to form a ring.
Claim 2
Dependent Claim

A surgical instrument for stitching up tissues with lengths of suture wire, comprising: a body in the form of a stem; a handle provided at one end of said body and a die at the other end, said die having the form of a curved needle with a guide groove provided in an inner concave portion thereof and serving to push the lengths of wire therealong; a rotatable magazine for the lengths of wire, freely mounted on said body; a pushrod reciprocably mounted with respect to said body; and a projection of said pushrod having a flat portion for engaging a length of the wire, and a curved groove therein for the final bending of the length of wire after it has left said guide groove; said pushrod pushing out the length of the wire from said magazine during its movement toward said die, pushing it along said guide groove, and bending it to form a ring.
Claim 3
Dependent Claim
70 words
The surgical instrument as defined in claim 1, wherein said magazine includes a rotatable bush with spaced-apart longitudinal slots on its outer surface; a rotatable cylindrical casing enveloping said bush and forming recesses together with said slots for the lengths of suture wire; and means for periodically turning said bush by a distance corresponding to the spacing between said slots, and for periodically turning said casing to its initial position.
Claim 4
Dependent Claim
106 words
The surgical instrument as defined in claim 2, wherein said turning means includes a spring and pins for limiting the rotation of said casing with respect to said body; further comprising a ratchet pawl made fast on said casing, interacting with said slots and effecting the combined turning of said bush and said casing in one direction; and wherein said casing has in its lateral wall an open-ended slot narrowing toward said die; one of the edges of said open-ended slot being inclined for interaction with said projection to turn said casing to a position where said pawl engages one of said slots of the bush.
