SURGICAL STAPLING INSTRUMENT HAVING A TWO-POSITION LOCKOUT MECHANISM

Surgical stapler systems can include lockout mechanisms to restrict further movement of a jaw assembly and provide different functionality when a jaw assembly is empty and when a partially or fully fired reload cartridge is present in the jaw assembly. When the jaw assembly is empty, the empty jaw a...

description Surgical stapler systems can include lockout mechanisms to restrict further movement of a jaw assembly and provide different functionality when a jaw assembly is empty and when a partially or fully fired reload cartridge is present in the jaw assembly. When the jaw assembly is empty, the empty jaw assembly lockout mechanism can arrest an open-close stroke of the jaw assembly. When an at least partially fired reload is present in the jaw assembly, a fired reload lockout mechanism can allow operation of the jaw assembly through a substantial portion of an open-close stroke, but restrict actuation of the jaw assembly in a firing stroke. The separate lockout mechanisms can be embodied in a single lockout lever actuatable by lockout actuators to three distinct positions or by two independently-operable lockout levers.
