Title
(EN) FOAM ELECTRODE FOR TISSUE RESECTION
(FR) ÉLECTRODE EN MOUSSE POUR RÉSECTION TISSULAIRE
Abstract
(EN)
Electro-surgery are provided for resecting a portion of tissue to be removed (e.g., unhealthy tissue, such as cancerous tissue) from a portion of the tissue to be retained (e.g., healthy tissue). An electrically conductive fluid, such as saline, may be absorbed into a hydrophilic electrode. Electrical energy (e.g., radio frequency (RF) energy) is conveyed to or from the hydrophilic electrode while being moved in proximity to the tissue along a resection line, whereby tissue adjacent to the resection line is coagulated. A resection member, such as a blunt resection member or a resection electrode, which may be on the same device as the hydrophilic electrode, is used to separate the tissue along the resection line.
(FR)
L'invention concerne des dispositifs d'électro-chirurgie pour résection d'une partie de tissu à retirer (par exemple, un tissu malade, tel qu'un tissu cancéreux) d'une partie de tissu à conserver (par exemple, un tissu sain). Un fluide électro-conducteur, tel qu'une solution saline, peut être absorbée par une électrode hydrophile. L'énergie électrique (par exemple, une énergie radiofréquence (R.F.)) est transportée vers l'électrode hydrophile ou à partir de celle-ci tout en étant déplacée à proximité du tissu le long d'une ligne de résection, le tissu adjacent à la ligne de résection étant coagulé. On utilise un élément de résection, tel qu'un élément de résection arrondi ou une électrode de résection, qui peut être sur le même dispositif que l'électrode hydrophile, pour séparer le tissu le long de la ligne de résection.
