Bipolar electric coagulation surgical scissors

Abstract

The invention discloses bipolar electric coagulation surgical scissors, belonging to the technical field of medical appliances. The bipolar electric coagulation surgical scissors comprise a handle assembly and a scissors clamp assembly, wherein the handle assembly comprises a fixed handle, a movable handle, a forceps lever, two pull levers, a wire and a plug, the fixed handle is connected with the movable handle, the forceps lever is sheathed into the fixed handle, and the pull levers pass through the forceps lever; an insulating layer is respectively arranged between the two pull levers and the forceps lever and between the two pull levers; the tail ends of the pull levers are connected with the wire, and the other end of the wire is connected with the plug; the scissors clamp assembly comprises two scissors clamps, scissors blades, a ceramic forceps base and forceps holder pins; the scissors blades are fixed on the scissors clamps; the ceramic forceps base is fixed at the front end of the forceps lever, the forceps holder pins pass through the ceramic forceps base and are fixed, and the two scissors clamps are sheathed into the forceps holder pins; and the tail ends of the scissors clamps are connected with the pull levers respectively. The bipolar electric coagulation surgical scissors disclosed by the invention have reasonable structure design, and can conduct electric coagulation hemostasis while shearing a tissue or an organ of a human body with no need of replacing surgical instruments. The bipolar electric coagulation surgical scissors are convenient for operation,and surgery efficiency can be improved by the adoption of the bipolar electric coagulation surgical scissors.

Description

technical field [0001] The invention relates to a pair of scissors for human endoscopic surgery, in particular to bipolar electrocoagulation surgical scissors, which are specially used for hemostasis and coagulation after shearing and separation of tissues in the human body, and belong to the field of medical equipment technology and machinery. Background technique [0002] Scissors are the most commonly used surgical instruments in minimally invasive endoscopic surgery. Scissors are used to cut some internal tissues during surgery, but they cannot stop the bleeding. Special instruments are needed to help coagulate the blood. At present, electrocoagulation forceps are generally used for hemostasis. Electrocoagulation forceps heat the tissue when the high-frequency and high-voltage current generated by the effective electrode tip contacts the body, so as to separate and coagulate the body tissue, thereby achieving the purpose of hemostasis.
