Bipolar coagulation forceps with knife

Abstract

The invention belongs to the technical field of medical treatment, and particularly relates to a bipolar coagulation forceps with a knife. The bipolar coagulation forceps comprises a handle and is characterized in that a sleeve is arranged on the handle and can axially move, a knife rod and two forceps rods are parallelly arranged in the sleeve in a penetrating manner, the forceps rods are fixed with the handle, forceps heads are arranged at the outer ends of the forceps rods, a blade is arranged at the outer end of the knife rod, a power supply structure is arranged on the handle, the knife rod and the forceps rods are made of conducting materials and connected with the power supply structure, a big trigger is arranged hinged to the handle, the inner end of the big trigger is connected with a first transmission mechanism, the first transmission mechanism can push the sleeve to axially move when the big trigger rotates, so that the actions of the forceps heads are controlled, a small trigger is hinged on the handle, the inner end of the small trigger is connected with a second transmission mechanism, and the second transmission mechanism can control the knife rod to move along the axial direction of the sleeve when the small trigger rotates. The bipolar coagulation forceps has the advantages that the forceps controls clamping of the forceps heads and cutting of the blade through cooperation of the big trigger and the small trigger and is simple to operate, and power is automatically connected in the cutting process.
