Electrosurgical system with suction control apparatus, system and method

摘要

System and method for selectively applying electrical energy to structures within or on the surface of a patient's body and controlling the flow of an electrically conductive fluid from the application site to provide or maintain a desired operating condition of the electrosurgical device. An electrosurgical probe is in communication with a fluid transport apparatus through a fluid transport lumen having an opening at an end proximate the application site and disposed proximate the electrosurgical probe. A controller in communication with the fluid transport apparatus provides control signals to the fluid transport apparatus in response to at least one operating parameter associated with the system. Based on the received control signals, the fluid transport apparatus adjusts a flow rate of the electrically conductive fluid at the application site through the fluid transport lumen in response to at least one operating parameter associated with the system.

1. A surgical method for treating tissue using an electrosurgical probe, the electrosurgical probe having a distal end including at least one active electrode, and a fluid transport lumen having an opening proximate the at least one active electrode, the method comprising:
positioning the distal end of the electrosurgical probe adjacent a target tissue; generating a high frequency voltage from a power supply between the at least one active electrode and a return electrode; measuring at least one operating parameter, wherein the at least one operating parameter is indicative of the status of the power supply in communication with the electrosurgical probe; processing an operating parameter input indicative of the status of the power supply; and controlling a fluid transport apparatus in communication with the fluid transport lumen based upon the operating parameter input; wherein controlling the fluid transport apparatus further comprises adjusting a fluid flow through the opening in response to the status of the power supply.
