Abstract
A surgical instrument for applying sutures of metal staples comprises an elongated staple inserting jaw and an elongated clinching jaw located alongside the former. The anterior operative tip of the staple inserting jaw contains magazines with staple recesses wherein staple driving members are also located, and the anterior operative tip of the clinching jaw has anvils located opposite said magazines and having grooves for bending the tips of said staples. The advancement of the driving members within the magazine recesses and the ejection of the staples is realized with the aid of an actuating bar located alongside the staple inserting jaw and being capable of moving longitudinally, and having an inclined camming surface at the tip facing the magazines that is intended for engaging with the staple driving members. The same tip of the actuating bar, somewhat rearwardly, has a pivotally connected disk-shaped knife for cutting the organs or tissues, the operative tip of the clinching jaw opposite said knife having an exchangeable elastic lining wherein the knife cuts in the course of tissue division.
