CIRCULAR STAPLER RELOAD

摘要

A circular stapler reload (10) is disclosed that can be releasably coupled to a stapler actuation device (20) to facilitate reuse of the stapler actuation device (20). The circular stapler reload (10) includes a cartridge assembly (22) having an annular staple cartridge (122) supporting staples, a stationary anvil assembly (24), and an integrated approximation and firing assembly (60). The approximation and firing assembly (60) operates to advance the cartridge assembly (22) towards the anvil assembly (24) from a spaced position to a clamped position and includes a lockout (98) to prevent firing of the reload prior to movement of the cartridge assembly (22) to the clamped position. The reload (10) also includes a lockout (170) which prevents movement of a drive member (64) of the approximation and firing assembly (60) until the reload (10) is secured to the actuation device (20).
