Electrosurgery with cooled electrodes
First Claim
Patent Images
1. An electrosurgery system comprising:
- an electrosurgical device having an electrode for applying electrical energy to tissue at a surgical site to heat and thus cut or stop bleeding of the tissue;
a cooling medium;
an internal cavity within the electrode for containing the cooling medium therein at the surgical site to cool the electrode; and
a gravity-fed closed circulation system that circulates the cooling medium through the internal cavity, the closed circulation system comprising;
a first container providing the cooling medium by gravity to the internal cavity, anda second container collecting the cooling medium as it exits the internal cavity.

Abstract
A cooled electrosurgical system includes an electrosurgical device having at least one electrode for applying electrical energy to tissue. In one embodiment, the electrode includes an internal cavity in which a cooling medium such as water is contained. The internal cavity is closed at the distal end of the device such that the cooling medium is contained within the electrode at the surgical site such that the cooling medium does not contact the tissue being treated.

12. A method of electrosurgery comprising:
-
applying electrical energy to tissue with an electrode at a surgical site to heat and thus cut or stop bleeding of the tissue; and cooling the electrode at the surgical site with a cooling medium contained within the electrode at the surgical site, said cooling comprising; providing the electrode with an internal cavity that contains the cooling medium, and providing a gravity-fed closed circulation system connected to the electrode, the closed circulation system including a first container providing the cooling medium by gravity to the internal cavity and a second container collecting the cooling medium as it exits the internal cavity.
