ABSTRACT:
A surgical instrument comprises an elongated body having a working zone at a distal end thereof. Kinematically connected between themselves and disposed within the body are: a mechanism for feeding wire into the working zone of the body, a mechanism for forming U-shaped staples from the wire, and a mechanism for reshaping U-shaped staples into rectangular ones, provided with a driver and anvils. The driver is connected with a reciprocating drive along the longitudinal axis of the body and is provided with a working portion in the form of two V-shaped projections. The anvil is disposed in the working zone of the body perpendicularly to its longitudinal axis in a plane of motion of the driver so that it can be moved out of this plane. The length of the anvil is less than the transverse side of the U-shaped staple.
