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.

Claims

1. 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.

2. The surgical device of claim 1, further comprising a feedback device in communication with the control circuit, wherein the feedback device is configured to indicate power delivered to the end effector.

3. The surgical device of claim 2, wherein the control circuit is configured to delay a predetermined amount of time between indicating a change in power delivered to the end effector and increasing the power delivered to the end effector by the transducer.

4. The surgical device of claim 2, further comprising a light source, wherein the light source indicates an amount of power delivered to the end effector by the transducer.

5. The surgical device of claim 2, further comprising a speaker configured to generate an audible signal indicating an amount of power delivered to the end effector by the transducer.

6. The surgical device of claim 2, wherein the device is configured to provide an audible signal as the force exerted on the trigger mechanism increases.

7. The surgical device of claim 1, wherein the control circuit is configured not to exceed a predetermined power delivered to the end effector by the transducer.

8. The surgical device of claim 1, further comprising a clamp arm pivotable toward the end effector about a pivot point.

9. The surgical device of claim 8, wherein the trigger mechanism is actuatable to pivot the clamp arm about the pivot point.

10. A method for processing a surgical instrument for surgery, comprising:

obtaining the surgical device of claim 1;

sterilizing the surgical device; and

storing the surgical device in a sterile container.

11. The surgical device of claim 1, wherein the trigger mechanism comprises at least one of a foot switch and a hand switch.
