Embodiment Construction

[0047] In order to improve the safety factor of the cutter and stapler and reduce the pain caused to surgical patients due to misfiring, the embodiment of the present invention provides a cutter and stapler. In the technical solution of the present invention, the nail pusher has a chute opened along the movement direction and a locking hole intersecting with the chute, and the safety body of the safety device is assembled on the nail box arm through an elastic member that can move between a high position and a low position. It has a locking position that interferes with the locking hole of the nail pusher frame when the insurance body is at a high position and a neck that is located in the chute of the nail pushing frame when the safety body is at a low position. The locking state of the firing device can be controlled by controlling the position of the safety body of the safety device, which greatly improves the safety factor of the cutter and stapler and reduces the pain caus...
