摘要:
An apparatus includes a body, a shaft, and a stapling head assembly. The body includes a chassis, a bracket, a coupling, and a conical coil. The bracket is configured to move relative to the chassis between first and second positions when selectively activated by a user. The bracket includes an upright member. The conical coil spring is disposed between the bracket and the coupling. The conical coil spring includes a proximal end, a distal end, a conical helical body disposed between the proximal and distal ends, and at least one dead coil disposed at the distal end of the conical coil spring that is configured to prevent the distal end of the conical coil spring from being retained between the bracket and the chassis. The shaft extends distally from the body. The stapling head assembly is positioned at a distal end of the shaft.
