Abstract
Electrosurgical devices that reduce surgery time while still adhering to surgical standards are provided. An electrosurgical device can include a tripolar configuration. A primary electrode can be used to generate a vapor pocket. A secondary electrode can be activated after the vapor pocket is generated. The vapor pocket can be steered to be between the primary and secondary electrodes and a surgery target.
Claims24
An electrosurgical device comprising:
- a return electrode exposed on an outer surface of a dielectric;
- a first electrode exposed on the outer surface of the dielectric;
- a second electrode exposed on the outer surface of the dielectric;
- and
- a suction port exposed on the outer surface of the dielectric and situated to (i) draw a vapor pocket generated by the first electrode to the second electrode and (ii) retain the vapor pocket at the suction port.

An electrosurgical system comprising:
- an electrosurgical device comprising:
- a dielectric;
- a return electrode exposed on an outer surface of the dielectric;
- a first electrode exposed on the outer surface of the dielectric;
- a second electrode exposed on the outer surface of the dielectric;
- an energy supply configured to provide energy to the electrosurgical device;
- a fluid outlet port configured to provide fluid to a target and situated to (i) push a vapor pocket generated by the first electrode to the second electrode and (ii) retain the vapor pocket at the second electrode;
- and
- control circuitry configured to, in response to detecting a vapor pocket at the first electrode, electrically connect the second electrode to the energy supply concurrently with the first electrode and cause fluid to flow to the fluid outlet port in response to detecting the vapor pocket.
6 more elements
A method of operating an electrosurgical system, the method comprising:
- providing, by an energy supply, energy to a first electrode of an electrosurgical device;
- detecting, by control circuitry, that a vapor pocket is generated by the first electrode by determining that a phase angle of the energy has changed by a first criterion;
- in response to detecting that the vapor pocket is generated, electrically connecting, by the control circuitry, a second electrode to the energy supply while the first electrode remains electrically connected to the energy supply;
- and
- activating a suction port to (i) draw a vapor pocket generated by the first electrode to the second electrode and (ii) retain the vapor pocket at the second electrode.
