A medical electric cutting and electrocoagulation device

Abstract

A medical electric cutting and electrocoagulation device, including a snare, a connecting tube, an insulating sleeve, an outer sheath, an electrocoagulation electrode, a traction rope, a handle seat, a sealing device, a catheter, a ventilation connector, an electrical connector and a handle; an outer sheath The proximal end is connected to the handle seat, the insulating sleeve and the electrocoagulation electrode are fixed on the inner wall of the distal end of the outer sheath, the snare is connected to the distal end of the traction rope through the connecting tube, the proximal end of the traction rope is connected to the catheter, and the catheter passes through the sealing device and connects with the catheter. The electric connector is connected, the handle base is provided with a ventilation joint, and the handle is assembled on the handle base and can reciprocate. The present invention has three functions of electric cutting, electric coagulation and edge electric cutting and electric coagulation at the same time, and has the advantages of simple structure and convenient operation, thereby shortening operation time, reducing operation difficulty and saving treatment cost.

Description

technical field [0001] The invention relates to a medical device used for strangulation, cauterization and cutting of polyps or tumors in the digestive tract and respiratory tract, and synchronously realizing blood coagulation function. It belongs to the field of medical equipment. Background technique [0002] Electric snares are routinely used to remove polyps or tumors of the digestive tract and respiratory tract under endoscopy. The principle is to use high-frequency current to generate high heat in the tissue that touches the snare, and then cauterize and cut off the polyps completely and quickly, and completely stop bleeding. [0003] Excision of polyps with traditional electric snare is often accompanied by intraoperative / postoperative bleeding. For patients on anticoagulant therapy, it is often necessary to stop taking anticoagulant drugs before surgery, which increases the risk of bleeding. Routine intraoperative bleeding, or use argon nozzle electrocoagulation to...
