Abstract

The invention relates to the technical field of preparation of medical animal experiment instruments, in particular to bipolar electric coagulation forceps of a brain model for an experimental animaland a preparation method of the bipolar electric coagulation forceps. The bipolar electric coagulation forceps comprise a left forceps rod, a right forceps rod and forceps tips fixed to the heads of the forceps rods, one or more forceps rod-forceps tip net-shaped disc structures are arranged between the left forceps rod and the right forceps rod or on the outer sides of the forceps rods, the net-shaped disc structures can serve as the forceps rods or buffer components between the forceps rods and contact walls, meanwhile, the net-shaped disc structures contain one or more anticoagulant or vascular smooth muscle cell hyperplasia inhibiting drugs, the problems of adhesion and the like can be solved, and the biocompatibility is good. The preparation method is simple, the bipolar electric coagulation forceps can be additionally used on various known bipolar electric coagulation forceps structures, and specific experiment application is facilitated.

Description

technical field [0001] The invention relates to the technical field of preparation of medical animal experimental instruments, in particular to a bipolar electrocoagulation tweezers for experimental animal brain models and a preparation method thereof. Background technique [0002] Bipolar coagulation began to be used as early as 1940. In 1966, Yasargil applied bipolar coagulation to microsurgery to discharge blood coagulation on microvessels. Its working principle is to connect the main body of the electrocoagulator through the tweezers wire, the tip of the tweezers clamps the bleeding port, the electrocoagulator releases the current, forms a circuit between the two tweezers, and provides high-frequency electric energy to the lesion tissue, making the bipolar The blood vessels between the two ends of the forceps are dehydrated and coagulated. Since the current only flows between the two tweezers, it will not cause burns to other parts, so it is very suitable for various ty...
