A bipolar coagulation device suitable for use in endoscopic surgery is disclosed which reduces the adhesion of tissue to the electrodes and enables the user to clean the electrodes during the procedure without removal from the body. Bipolar electrocautery forceps are located at the distal end of a sheath suitable for use in endoscopic surgery. The tips of the forceps are manipulated using controls located at the control end of the sheath which remains outside the patient's body. The tips of the forceps are made of material having phosphorous in combination with metals of high thermal conductivity, which reduces the adhesion of tissue during cauterization. In addition, the device has a cleaner which acts to free the forceps of any adhering debris. This cleaning can be done inside the patient's body, without the need for any additional instrumentation. In a preferred embodiment, the tips of the bipolar coagulation device can also be pivoted to an angularly disposed position.
An endoscopic bipolar coagulation device, comprising:
A method of coagulating internal tissue of a mammal using a device of the type comprising a sheath, an electrocautery forceps having tips at the distal ends thereof, and a wedge on at least one arm of the forceps, comprising:
