Abstract

The present disclosure is directed to an electrosurgical instrument having a housing that includes a generator configured to output electrosurgical energy and a controller configured to control the output of the generator. The instrument also includes a switch coupled to the controller and configured to provide a signal to the controller to select the energy modality of the electrosurgical energy. An indicator is also included to provide an indication of the selected energy modality.

First claim

What is claimed is:

1. A handheld electrosurgical instrument, comprising:
a housing including a generator configured to output electrosurgical energy;
an elongated shaft directly coupled to the housing;
an end effector disposed at a distal portion of the elongated shaft;
a handle assembly coupled to the housing; and
a control unit removably and directly coupled to the housing, the control unit including:
a controller configured to control the output of the generator; and
a touch screen configured to permit a user to select an energy modality of the electrosurgical energy and to provide a signal to the controller based on the selected energy modality.

2. The handheld electrosurgical instrument according to claim 1 , wherein the energy modality includes an energy level and the touch screen provides an indication of the energy level.

3. The handheld electrosurgical instrument according to claim 1 , wherein the energy modality includes an energy mode and the touch screen provides an indication of the energy mode.

4. The handheld electrosurgical instrument according to claim 1 , wherein the energy modality includes an energy level and an energy mode and the touch screen provides an indication of the energy level and the energy mode.

5. The handheld electrosurgical instrument according to claim 1 , wherein the touch screen is configured to receive clinician identification information and/or patient identification information.

6. The handheld electrosurgical instrument according to claim 5 , where the touch screen displays information corresponding to the clinician identification information and/or the patient identification information.

7. The handheld electrosurgical instrument according to claim 1 , wherein the touch screen is configured to receive biometric information.

8. The handheld electrosurgical instrument according to claim 7 , further comprising a memory having biometric information stored thereon and the controller compares the received biometric information to the biometric information stored in a memory.

9. The handheld electrosurgical instrument according to claim 1 , further comprising a memory having a plurality of energy modalities stored thereon.

10. The handheld electrosurgical instrument according to claim 1 , further comprising an end effector operably coupled to the housing.

11. The handheld electrosurgical instrument according to claim 10 , wherein the end effector is coupled to the generator and is configured to output electrosurgical energy to tissue.
