Abstract
An electrosurgical smoke evacuation pencil includes a handle housing having a proximal end portion and a distal end portion, the handle housing defining a lumen therethrough, a nozzle in fluid communication with the lumen, a pressure sensor configured to sense a vacuum pressure at the nozzle, a connector coupled to the distal end portion of the handle housing, the connector configured to couple to a suction source, and an electrode configured to couple to a source of electrosurgical energy.
Claims20
An electrosurgical pencil comprising:
- a handle housing having a proximal end portion and a distal end portion, the handle housing defining a lumen therethrough;
- a nozzle in fluid communication with the lumen;
- a pressure sensor configured to sense a vacuum pressure at the nozzle;
- a connector coupled to the distal end portion of the handle housing, the connector configured to couple to a suction source;
- and
- an electrode configured to couple to a source of electrosurgical energy.
3 more elements
A surgical smoke evacuation system, comprising:
- a smoke evacuator including a suction generator configured to create a vacuum pressure;
- an electrosurgical pencil including:
- a nozzle;
- and
- a pressure sensor configured to sense vacuum pressure at the nozzle;
- a suction conduit coupling the nozzle to the smoke evacuator;
- a valve configured to reduce the vacuum pressure from the nozzle;
- a processor;
- and
- a memory, including instructions stored thereon which, when executed by the processor, cause the surgical smoke evacuation system to:
- sense the vacuum pressure at the nozzle;
- and
- actuate the valve to an open position based on the sensed pressure.
