Abstract

The invention discloses a mammary gland biopsy excision blood coagulation device with a radio frequency coagulation cutter tube. The device comprises an outer tube rotating gear, a linear driving gear, a radio frequency electric connecting piece, a sample collector, a vacuum catheter kit, a puncture cutter, a sampling groove, an outer tube, a cutting knife tube, an indicating shaft sleeve, a connecting piece and an outer tube rotating device. According to the invention, the cutting edge part of the cutting knife tube is changed into a surgical electrode of a radio frequency coagulation cuttingdevice, radio frequency current passes through the cutting edge of the cutting knife tube and is conducted to pathological tissues to be cut, and bleeding is stopped while the tissues are cut. Because the cutting is not a mechanical mode, the problem that a cutting edge becomes blunt does not exist. Meanwhile, calcification points can be crushed through spark discharge. A heat affected zone generated by discharge energy can play a blood coagulation effect.

Description

technical field [0001] The invention relates to the field of medical equipment, and more specifically relates to a breast biopsy excision coagulator with a radio frequency coagulation knife tube. Background technique [0002] Vacuum-assisted breast biopsy system is a minimally invasive medical device in breast surgery and has been applied in clinical practice. The system consists of a control system, breast biopsy resectator, and vacuum negative pressure system. The mammary gland biopsy resectator is composed of an outer cover, a puncture knife, a cutting knife tube, an outer tube, a sampling tank, a sample collector, a vacuum catheter kit, and the like. Mainly use the vacuum auxiliary device to suck the diseased tissue into the sampling tank through vacuum negative pressure, the cutting knife tube rotates quickly to cut the diseased tissue sucked into the sampling tank, and then suck the diseased tissue into the sample collector through negative pressure after cutting.
