Abstract

The surgical instrument for applying a staple suture comprises a body with a split frame having a .andgate.-shaped member, whose one leg carries a die with a number of recesses. There is provided a detachable rod adapted to interlink the free ends of the legs of the .andgate.-shaped member, said rod having stops which embrace from outside the free ends of the legs of the .andgate.-shaped member so as to form, together with said free ends, a lock joint featuring a retainer of the rod position, said retainer being in fact a shoulder provided at the free end of each of said legs. The free ends of the legs are capable of moving towards each other due to resilience of the .andgate.-shaped member, the amount of the abovesaid travel of the free ends of the legs towards each other depending upon the size of the retaining shoulder, while the detachable rod and the free ends of the legs are adapted to enter each other along the legs so as to interact through the flat spots provided thereon. The instrument has also a die with the staple bending recesses, a staple head carrying a staple magazine and an ejector and being mounted slidably in the frame, as well as mechanical actuators of the staple head and ejector.
