PURPOSE: To provide a bipolar electric pincette generating no deformation or deterioration even if sterilized by a high pressure steam sterilization method by forming a housing part fixing the bipolar electrodes connected to a high frequency generator from a synthetic resin specified in thermal deformation temp. and water absorption and fixing two arm parts by a resinous adhesive. CONSTITUTION: A bipolar pincette 1 has two arm parts 2, 3 and the leading end parts 8 of them are set to current supply parts and the titanium alloy constituting the arm parts is exposed. The surfaces of the other arm parts are coated with a resin having insulating action. The arm parts 2, 3 are connected to electrodes 5, 6 and mutually insulated in a housing part 7 made of a fiber reinforced polyphenylene sulfide resin with thermal deformation temp. (18.6kgf/cm) of 138 deg.C or higher and water absorption (24hr) of 0.2% or less and fixed by an acid anhydride curable epoxy adhesive with thermal deformation temp. of 165 deg. or higher. The arm parts 2, 3 are energized so as to be held to an open state on the leading end side thereof at a usual time. |
