ROBOTICALLY-CONTROLLED MOTORIZED SURGICAL INSTRUMENT WITH AN END EFFECTOR

摘要

A surgical tool configured for operation in connection with a robotic system. The surgical tool includes a shaft and an end effector extending distally from the shaft. The end effector comprises a first jaw member and a second jaw member movable relative to the first jaw member from a closed position to an open position in response to at least one axial motion. In addition, the surgical tool includes a motor configured to generate at least one rotational motion and a motion conversion assembly operably coupled to the motor and the second jaw member, wherein the motion conversion assembly is configured to convert the at least one rotational motion to the at least one axial motion.

1. A surgical end effector, comprising:
a first jaw member; a second jaw member movable relative to the first jaw member between and open position and a closed position; camming means for camming the second jaw member relative to the first jaw member from the open position to the closed position and for camming the second jaw member relative to the first jaw member from the closed position to the open position, wherein the camming means is configured to apply actuation forces onto the first jaw member and the second jaw member simultaneously to move the second jaw member relative to the first jaw member from the open position to the closed position; and rotary input means for driving the camming means.
