Abstract

Claims (38)

1 . A control circuit, to:

receive a first input corresponding to a user selection;

receive a second input corresponding to an impedance measurement;

receive a combined signal from a generator, wherein the combined signal comprises an RF component and an ultrasonic component; and

select between a first mode and a second mode of treating tissue based on the first input and the second input, wherein:

the first mode comprises providing the RF component of the combined signal to an electrode of a surgical instrument; and

the second mode comprises providing the ultrasonic component of the combined signal to an ultrasonic blade of the surgical instrument.

2 . The control circuit of claim 1 , further to receive a third input corresponding a position of a clamp arm of the surgical instrument.

3 . The control circuit of claim 2 , wherein selecting between the first mode and the second mode is further based on the third input.

4 . The control circuit of claim 1 , further to select a third mode of treating tissue based on the first input and the second input, wherein the third mode comprises providing the RF component of the combined signal to the electrode and providing the ultrasonic component of the combined signal to the ultrasonic blade.

5 . The control circuit of claim 1 , further to select a third mode of treating tissue based on the first input and the second input, wherein the third mode comprises abstaining from providing the RF component or the ultrasonic component to the surgical instrument.

6 . The control circuit of claim 1 , further to determine a short circuit condition or an open circuit condition based on the received second input.

7 . The control circuit of claim 1 , further to control an energy level of the RF component and the ultrasonic component based on the first input and the second input.

8 . A control circuit, to:

receive a first input corresponding to a position of a clamp arm of a surgical instrument;

receive a second input corresponding to an impedance measurement;

receive a combined signal from a generator, wherein the combined signal comprises an RF component and an ultrasonic component; and

select between a first mode and a second mode of treating tissue based on the first input and the second input, wherein:

the first mode comprises providing the RF component of the combined signal to an electrode of a surgical instrument; and

the second mode comprises providing the ultrasonic component of the combined signal to an ultrasonic blade of the surgical instrument.

9 . The control circuit of claim 8 , further to receive a third input corresponding a user selection.

10 . The control circuit of claim 9 , wherein selecting between the first mode and the second mode is further based on the third input.

11 . The control circuit of claim 8 , further to select a third mode of treating tissue based on the first input and the second input, wherein the third mode comprises providing the RF component of the combined signal to the electrode and providing the ultrasonic component of the combined signal to the ultrasonic blade.

12 . The control circuit of claim 8 , further to select a third mode of treating tissue based on the first input and the second input, wherein the third mode comprises abstaining from providing the RF component or the ultrasonic component to the surgical instrument.

13 . The control circuit of claim 8 , further to determine a short circuit condition or an open circuit condition based on the received second input.

14 . The control circuit of claim 8 , further to control an energy level of the RF component and the ultrasonic component based on the first input and the second input.

15 . A control circuit, configured to:

receive a first input corresponding to a user selection;

receive a second input corresponding to an impedance measurement;

receive a combined signal from a generator, wherein the combined signal comprises an RF component and an ultrasonic component;

determine if the RF component of the combined signal is to be provided to a surgical instrument based on the first input and the second input; and

determine if the ultrasonic component of the combined signal is to be provided to the surgical instrument based on the first input and the second input.

16 . The control circuit of claim 15 , further to receive a third input corresponding to a position of a clamp arm of a surgical instrument.

17 . The control circuit of claim 16 , wherein:

determining if the RF component of the combined signal is to be provided to the surgical instrument is further based on the third input; and

determining if the ultrasonic component of the combined signal is to be provided to the surgical instrument is further based on the third input.

18 . The control circuit of claim 16 , further to determine a short circuit condition or an open circuit condition based on the received second input.
