Technical Field

[0001] The utility model relates to a handle of an electrocoagulation forceps and belongs to the field of medical equipment. Background Art

[0002] Electrocoagulation hemostasis is a medical method that uses the thermal effect of high-frequency electric current to cause the blood vessel wall to dehydrate and shrink, the blood in the blood vessel to coagulate, and the blood vessel and blood clot to merge into one, thereby achieving the purpose of effective hemostasis.

[0003] Electrocoagulation forceps are used for intraoperative hemostasis. The electrocoagulation forceps include a handle, a core and a head. The two ends of the core are respectively connected to the handle and the head. The opening and closing of the head is controlled by the handle. Currently, most of the handles and cores of the electrocoagulation forceps are integrated into one structure, rather than installed through a locking structure. Therefore, the core cannot be disassembled. At the same time, most of the current electrocoagulation forceps are not equipped with structures such as a ball and a spring. When the core is rotated, it is impossible to know whether the ball is bounced into the concave hole. Utility Model Content
