More Information
Summary:A surgical instrument and method of compressing tissue includes an end effector and a shaft assembly. The end effector has a jaw and a clamp arm movable between open and closed positions. The shafts assembly includes a clamp actuator having a proximal actuator portion, a distal actuator portion, and a force limiter. The force limiter is longitudinally connected between the proximal and distal actuator portions and configured to transfer movement from the proximal actuator portion to the distal actuator portion up to transferring a predetermined force therethrough. At least a portion of the force limiter is configured to deflect upon exceeding the predetermined force such that the proximal actuator portion is configured to longitudinally move relative to the distal actuator portion and thereby limit a clamping force between the jaw and the clamp arm.
