Abstract

The invention relates to a gripper jaw used for a heat setting cutter, which comprises jaw bodies (1), wherein an electric heating wire (3) is arranged on the jaw bodies and a jaw shell (4) is arranged outside the jaw bodies. The gripper jaw is characterized in that a connection block (1b) is arranged on the inner side surface of the rear end of each jaw body; a butt strap (1a) is arranged on the outer side surface of the rear end of each jaw body; an isolation layer (2) is connected with a gripping part of each jaw body (1) in a matched manner; the electric heating wire (3) is connected into the isolation layers in a matched manner; the matched assembly of the jaw bodies, the isolation layers and the electric heating wire is wrapped by the jaw shell (4); a temperature sensor is also arranged in the jaw shell, and is in matched contact with the electric heating wire. The invention has the following advantages: the gripper jaw is convenient to manufacture; in the clamping stress state, the stress on the electric heating wire is uniform; the heat quantity of the jaw body is low during working, so that the real-time closed-loop control on the working temperature of the electric heating wire is facilitated; the temperature of the electric heating wire is accurately set, so that the gripper jaw is uniformly heated, and the phenomenon of overheating wire break can be completely avoided.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to a clamping claw for a thermocoagulation cutting knife. Background technique [0002] Minimally invasive surgery is performed using modern medical instruments such as laparoscopy and thoracoscopic surgery and related equipment. It has the advantages of less trauma, less pain, and faster recovery. With the development and progress of technology, minimally invasive surgery has penetrated into various fields of surgery. [0003] The thermocoagulation cutting knife is one of the most important instruments of the thermal welding technology system in minimally invasive surgery. The clamping claw is one of the important parts of the thermocoagulation cutting knife. Uniform and deformed, the energy of the hot wire will be transmitted to the claw body in a large amount during long-term surgery, making the temperature of the claw body high, and in severe cases, it will burn the tissues in ...
