AN ELECTROSURGICAL DEVICE FOR COAGULATING AND FOR MAKING INCISIONS, A METHOD OF SEVERING BLOOD VESSELS AND A METHOD OF COAGULATING AND FOR MAKING INCISIONS IN OR SEVERING TISSUE

摘要

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.
