Medical electric incision and coagulation device

Abstract

A medical electric incision and coagulation device comprises a ring sleeve, a connecting pipe, an insulating sleeve, an outer sheath tube, an electric coagulation electrode, a hauling rope, a handle seat, a sealing device, a catheter, a vent connector, an electrification connector and a handle, wherein the near end of the outer sheath tube is connected with the handle seat; both the insulated sleeve and the electric coagulation electrode are fixed on the inner wall of the far end of the outer sheath tube; the ring sleeve is connected with the far end of the hauling rope through the connecting pipe; the near end of the hauling rope is connected with the catheter; the catheter passes over the sealing device and then is connected with the electrification connector; the vent connector is arranged on the handle seat; the handle is assembled on the handle seat and can reciprocate. The medical electric incision and coagulation device has the three functions of electric incision, electric coagulation and edge electric incision and coagulation, and has the advantages of being simple in structure and convenient to operate, so that the operation time is shortened, the operation difficulty is reduced and the treatment cost is lowered.

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...
