Abstract

The invention discloses dripping bipolar electric coagulation forceps for endoscopes of lateral skull base surgeries, which comprise two forceps bodies and an electrode holder, the tail ends of the two forceps bodies are electrically connected with an electrode holder, each forceps body comprises a forceps rod part and a tip part, an insulating sleeve is arranged on the outer surface of each forceps rod part, and the tip part is located at the head end of the forceps rod part, wherein a water channel is formed in the two forceps rod parts in the extending direction, a water outlet of the waterchannel is formed close to the tip part, the forceps also comprise a pressure pump, a water inlet of the pressure pump is used for being connected with a water conveying guide pipe, and a water outlet of the pressure pump is communicated with a water inlet of the water channel. And various included angles are formed between the tip part and the forceps rod part or the tip part is bent relative tothe forceps rod part. By means of the arrangement, the problems that the tips of existing bipolar coagulation forceps cannot meet the requirements of various angles, and the water outlet mode cannotmeet the requirements are solved.

Description

technical field [0001] The present application relates to the technical field of medical devices, and more specifically, to a dripping bipolar electrocoagulation forceps for lateral skull base surgery endoscope. Background technique [0002] Bipolar electric coagulation tweezers can carry out finer electrocoagulation and hemostasis and treatment of small blood vessels and other structures. The principle is to heat the protein coagulation blood vessel closure tissue to the coagulation and boiling point at the same time, and then automatically cut off the power. At the same time, due to the insulation of the blades of the bipolar coagulation forceps, only the tweezers conduct current between the tweezers. During electrocoagulation, the current flows from one tweezers tip to the other tweezers tip. Less or not affected, but has a protective effect on brain tissue. Bipolar coagulation tweezers also have the functions of separation and clamping. The bipolar coagulation tweezers...
