A method of manufacturing bipolar coagulation forceps, the method comprising the operations of: respectively manufacturing a forceps tip and a forceps handle, wherein the forceps tip is made of copper-based alloy and/or gold-based alloy and/or silver-based alloy, and the forceps handle is made of iron-based, copper-based, nickel-based or titanium-based material; polishing the tip of the forceps, wherein the surface roughness of the tip of the forceps is less than or equal to 3.2 microns; the forceps handle is provided with an electrode seat and a lead, and the lead is electrically connected with the forceps handle or the lead is electrically connected with the forceps tip; splicing and fixing the forceps tip and the forceps handles together to form a complete forceps valve, attaching an insulating layer outside the two forceps handles, and exposing the electrode holder out of the insulating layer; either electrode holder can be used as a positive electrode or a negative electrode. The invention has the advantage that the forceps tip can achieve good biological tissue adhesion resistance only by depending on the self performance. |
