| abstract |
An electrosurgical device for coagulating and for making incisions in or severing tissue such as blood vessels, the device comprising forceps jaws (6, 7) for immobilising a tissue portion to be coagulated and incised, the forceps jaws (6, 7) being connected to means for applying an electrical tension between said forceps jaws for coagulating the tissue portion, the device further comprising a member (22) for being displaced between said forceps jaws (6, 7) to incise a tissue portion held between the forceps jaws and coagulated thereby, the member (22) being connected to means for applying an electrical voltage to said member for performing an incision in said tissue by means of said electrical voltage applied to said member (22), the member (22) preferably being blunt such that the incision substantially exclusively is achieved by means of the voltage applied to the member (22). For preventing the generation of smoke through charring of the tissue portion, a tube is provided for supplying an electrically non-conductive, cooling liquid to the tissue portion. |
