Abstract

A staple head includes a first jaw and a second jaw, a connecting member, a stop member and a firing mechanism. The connecting member is connected to proximal ends of the first jaw and the second jaw. The stop member is rotatably mounted on the connecting member and includes a first blocking portion. The firing mechanism is movable along an axial direction of the stapler and includes a second blocking portion. In a first state, the first blocking portion is located on a path where the second blocking portion moves in a direction toward a distal end side. When an external force is applied to the stop member, the stop member rotates relative to the connecting member in a first direction such that the first blocking portion moves in a direction away from an axial center of the stapler, the stop member enters a second state.
