Patent attributes
A stapling system is disclosed. The stapling system comprises a housing comprising a first rotary input and a second rotary input, an elongate shaft, an end effector, a closure cam, and an opening member. The end effector comprises a jaw and an anvil comprising a cam surface. The anvil is rotatable relative to the jaw between an open position and a clamped position. The closure cam is operably coupled with the first rotary input and is configured to engage the cam surface to move the anvil toward the clamped position in response to an input motion from the first rotary input. The opening member is configured to apply an opening force to the anvil at a location other than the cam surface to move the anvil toward the open position in response to an input motion from the second rotary input.
