Electrosurgery irrigation primer systems and methods
First Claim
1. An electrosurgical system comprising:
- a high frequency power supply;
a fluid delivery system;
a handheld device comprising at least one electrode; and
at least one connector for connecting the handheld device to the fluid delivery system and the high frequency power supply, wherein the electrosurgical system is configured to deliver a radiofrequency (RF) current and fluid until a threshold current level indicative of purging completion is detected causing the fluid delivery system and the high frequency power supply to deactivates;
wherein the fluid delivery system comprises a fluid control element and a fluid source comprising an electrically conductive irrigation fluid, and wherein the fluid control element is an electromechanical device for controlling fluid delivery without making direct contact with the electrically conductive irrigation fluid.

Abstract
Systems and methods are provided for priming or purging an electrosurgical fluid irrigation system. The electrosurgical system can include a high frequency power supply, a fluid delivery system, a handheld device having one or more electrodes, and one or more connectors for connecting the handheld device to the fluid delivery system and the RF generator. The electrosurgical system may be configured to deliver RF current and irrigation fluid until a threshold current level is detected, which is indicative of a continuous flow of fluid at the electrode and purging completion. The systems and methods of purging an electrosurgical system may further include dynamically controlling an RF output and fluid delivery system in accordance with varied parameters of detected threshold current levels.

19. An electrosurgical system comprising:
-
a high frequency power supply; a fluid delivery system; a handheld device comprising at least one electrode; and at least one connector for connecting the handheld device to the fluid delivery system and the high frequency power supply, wherein the electrosurgical system is configured to deliver a radiofrequency (RF) current and fluid until a threshold current level indicative of purging completion is detected causing the fluid delivery system and the high frequency power supply to deactivate; wherein the electrosurgical system is configured such that delivery of the RF current and the fluid automatically start once the handheld device is connected to the fluid delivery system and the high frequency power supply.
