Cartridge based lockout mechanism for right angle surgical stapler

A surgical stapler includes a body, a shaft assembly, and an end effector configured to receive a staple cartridge. The end effector is actuatable between an open state for receiving tissue and a closed state for clamping the tissue. A closure system operatively coupled with the end effector is oper...

Summary:A surgical stapler includes a body, a shaft assembly, and an end effector configured to receive a staple cartridge. The end effector is actuatable between an open state for receiving tissue and a closed state for clamping the tissue. A closure system operatively coupled with the end effector is operable to actuate the end effector from the open state to the closed state. A firing system operatively coupled with the end effector is actuatable to fire the end effector to staple and cut the clamped tissue. A lockout member operatively coupled with the closure system and the firing system is configured to inhibit actuation of the closure system to prevent closure of the end effector when an unspent staple cartridge is absent from the end effector. The lockout member is also configured to inhibit actuation of the firing system to prevent repeated firing with the same staple cartridge.
