Abstract

Claims (37)

1 . A system, comprising:

a surgical device useable in a sterile field, the surgical device comprising a first control circuit to selectively control the surgical device;

an actuator communicatively coupled to the first control circuit, wherein an actuation of the actuator is configured to implement a surgical function by the surgical device; and

a sterile field display separate from the surgical device, wherein the sterile field display comprises a second control circuit communicatively coupled to the first control circuit, wherein the second control circuit comprises a user interface configured to receive a user input, and wherein the second control circuit is configured to:

receive an input signal from the user interface indicative of an adjustment to the surgical function associated with the actuator; and

transmit an output signal to the first control circuit based on the input signal.

2 . The system of claim 1 , wherein the surgical device further comprises an indicator switchable between a plurality of indicator states comprising a first indicator state and a second indicator state, wherein the output signal is configured to switch the indicator between the first indicator state and the second indicator state.

3 . The system of claim 2 , wherein the indicator comprises a light, wherein the first indicator state comprises a first color of the light, wherein the second indicator state comprises a second color of the light.

4 . The system of claim 1 , wherein the sterile field display comprises a handheld screen.

5 . The system of claim 4 , wherein the user interface comprises a touch screen.

6 . The system of claim 5 , wherein the surgical device comprises an electrosurgical tool.

7 . The system of claim 1 , wherein the sterile field display is physically separate from the surgical device.

8 . The system of claim 1 , wherein the sterile field display is movable relative to the surgical device within the sterile field.

9 . The system of claim 1 , wherein the sterile field display is discrete from the surgical device.

10 . A system, comprising:

a surgical device comprising a first control circuit to selectively control the surgical device;

an actuator communicatively coupled to the first control circuit, wherein an actuation of the actuator is configured to implement a surgical function by the surgical device; and

a screen separate from the surgical device, wherein the screen comprises a second control circuit communicatively coupled to the first control circuit, wherein the second control circuit comprises a user interface configured to receive a user input, and wherein the second control circuit is configured to:

receive an input signal from the user interface indicative of an adjustment to the surgical function associated with the actuator; and

transmit an output signal to the first control circuit based on the input signal;

wherein the surgical device comprises an electrosurgical tool; and

wherein, in a first state, the electrosurgical tool is configured to transmit a first waveform, wherein, in a second state, the electrosurgical tool is configured to transmit a second waveform, and wherein the second waveform is different than the first waveform.

11 . The system of claim 10 , wherein the first waveform is configured to coagulate tissue, and wherein the second waveform is configured to cut tissue.

12 . A system, comprising:

an electrosurgical tool comprising a first control circuit, wherein, in a first state, the electrosurgical tool is configured to transmit a first waveform and, in a second state, the electrosurgical tool is configured to transmit a second waveform different from the first waveform;

an actuator communicatively coupled to the first control circuit, wherein an actuation of the actuator is configured to implement a surgical function by the electrosurgical tool; and

a screen separate from the electrosurgical tool, wherein the screen comprises a second control circuit communicatively coupled to the first control circuit, wherein the second control circuit comprises a user interface configured to receive a user input, and wherein the second control circuit is configured to:

receive an input signal from the user interface indicative of an adjustment to the surgical function associated with the actuator; and

transmit an output signal to the first control circuit based on the input signal.

13 . The system of claim 12 , wherein the electrosurgical tool further comprises an indicator switchable between a plurality of indicator states comprising a first indicator state and a second indicator state, wherein the output signal is configured to switch the indicator between the first indicator state and the second indicator state.

14 . The system of claim 13 , wherein the indicator comprises a light, wherein the first indicator state comprises a first color of the light, wherein the second indicator state comprises a second color of the light.

15 . The system of claim 12 , wherein the screen comprises a handheld screen.

16 . The system of claim 12 , wherein the user interface comprises a touch screen.

17 . The system of claim 12 , wherein the first waveform is configured to coagulate tissue, and wherein the second waveform is configured to cut tissue.

18 . The system of claim 12 , wherein the screen is physically separate from the electrosurgical tool.

19 . The system of claim 12 , wherein the screen is movable relative to the electrosurgical tool within a sterile field.

20 . The system of claim 12 , wherein the screen is discrete from the electrosurgical tool.
