Abstract
A surgical device. The surgical device may comprise a transducer configured to provide vibrations along a longitudinal axis and an end effector coupled to the transducer and extending from the transducer along the longitudinal axis. The surgical device also may comprise a lower jaw extending parallel to the end effector. The lower jaw may comprise a clamp face extending toward the longitudinal axis. Also, the lower jaw may be slidable relative to the end effector to bring the clamp face toward a distal end of the end effector.
Claims11
A surgical device comprising:
- a transducer configured to energize an end effector, wherein the end effector is coupled to the transducer;
- a trigger mechanism actuatable to cause the end effector to be energized;
- a sensor positioned to sense a force exerted on the trigger mechanism;
- and
- a control circuit in communication with the sensor, wherein the control circuit is configured to:
- provide power to the end effector in response to an actuation of the trigger mechanism;
- receive from the sensor a signal indicating an increase in the force exerted on the trigger mechanism after the actuation of the trigger mechanism;
- and
- increase the power delivered to the end effector by the transducer in response to the signal.
