Abstract:
1. An electrosurgical device, comprising: (a) a handpiece, wherein the handpiece includes a pivoting trigger; (b) a shaft extending distally from the handpiece, the shaft having a distal end; (c) an end effector at the distal end of the shaft, the end effector comprising: (d) a jaw closure feature operable to move the first jaw toward the second jaw; (e) an electromechanical driver operable to drive the jaw closure feature to move the first jaw toward the second jaw; (f) a sensor configured to sense an operational parameter associated with the jaw closure feature; and (g) a braking feature comprising a pair of pads, wherein the braking feature is operable to selectively provide variable frictional resistance against pivotal movement of the pivoting trigger by driving the pair of pads against an exterior surface of the pivoting trigger, wherein the braking feature is operable to vary the frictional resistance based on data from the sensor.
