Abstract

A surgical instrument includes a shaft assembly, a handle assembly, and a latch system configured to operatively couple the shaft and handle assemblies. The latch system includes shaft and a handle lock members respectively connected to the shaft and handle assemblies for inhibiting operative uncoupling of the shaft and handle assemblies. The latch member has a cam surface and a latch member. The latch member is configured to selectively move from a locked position to a released position such that movement of the latch member causes the shaft and handle lock members to disengage and uncouple the shaft and handle assemblies. The latch member is further configured to selectively move from the released position to a removal position such that further movement of the latch member causes the cam surface of the latch member to engage the cam base and urge the shaft assembly in a removal direction.
