Abstract

A system and apparatus for controlling operating room equipment during an electrosurgical procedure is disclosed. The system includes an electrosurgical generator, a controller in electrical communication with and configured to control the electrosurgical generator and at least one operating room device, and a handpiece having a housing and a cable extending proximally from the housing providing electrical connection to the controller, the handpiece further includes first controls for controlling the generator and second controls for controlling at least one operating room device.

Claims

1. A system for controlling and effecting activation of operating room equipment disposed outside a sterile field during an electrosurgical procedure inside the sterile field, the system comprising:

an electrosurgical generator configured to deliver energy to the sterile field and including a controller;

the controller being in electrical communication with and configured to control the electrosurgical generator and at least one operating room device disposed outside the sterile field to produce an effect outside the sterile field; and

a handpiece having a housing and a cable extending from the housing providing electrical connection to the controller, the handpiece further includes first controls for controlling the generator and second controls for controlling and effecting activation and adjustment of at least one operating room device disposed outside the sterile field to produce an effect outside the sterile field, including;

activation and adjustment of an operating room bed;

activation and adjustment of an operating room light source; and

activation and adjustment of an insufflation device;

wherein each of the first and second controls is in direct electrical communication with the controller, wherein the second controls include at least one sliding controller for activating and adjusting the at least one operating room device.

2. A system as in claim 1, wherein the first controls include at least one first activation switch supported on the housing, the at least one first switch being configured and adapted to selectively complete a control loop extending from the controller upon actuation thereof.

3. A system as in claim 1, wherein the second controls include at least one second activation switch supported on the housing, the at least one second switch being configured and adapted to selectively complete a control loop extending from the controller upon actuation thereof.

4. A system as in claim 1, wherein the first controls include at least one first voltage divider network supported on the housing, the at least one first voltage divider network being electrically connected to the controller.

5. A system as in claim 4, wherein the at least one first voltage divider network is a potentiometer.

6. A system as in claim 5, wherein the potentiometer has discrete values.

7. A system as in claim 1, wherein the second controls include at least one second voltage divider network supported on the housing, the at least one second voltage divider network being electrically connected to the controller.

8. A system as in claim 7, wherein the at least one second voltage divider network is a potentiometer.

9. A system as in claim 8, wherein the potentiometer has discrete values.

10. An apparatus as in claim 1, wherein the first controls include at least one sliding controller for adjusting the intensity of the energy of the electrosurgical generator.
