Cutting saw blade mechanism for percutaneous puncture drainage

Abstract

The invention relates to a cutting saw blade mechanism for percutaneous puncture drainage. The mechanism comprises a puncture sheath tube and a puncture needle core movably connected into the sheath tube in a sleeved mode, the sheath tube is of a hollow tubular structure with the two ends open, and one end of the sheath tube is in a tip shape; a plurality of continuously-arranged sawteeth are arranged on one side of the needle core, tooth tips of the sawteeth incline towards the tip end of the sheath tube, and the end, making contact with the sawteeth, of the needle core is of a structure withthe rhombic cross section. The sawteeth penetrate through the tip of the sheath tube; scale marks are arranged at the other end of the needle core; the needle core is further sleeved with an adjusting nut, and the adjusting nut is located outside the sheath tube; and a limiting part is further arranged on the outer side surface of the sheath tube and close to one end of the adjusting nut. The device is high in functionality and can be widely applied to the technical field of medical equipment.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a cutting saw blade mechanism for percutaneous puncture and drainage. Background technique [0002] Clinically, infectious effusions separated by multiple cavities and encapsulated abscesses often require percutaneous B-ultrasound positioning for puncture and catheter drainage, but in fact, there is often the problem that one-time drainage is difficult to succeed, thus causing multiple pains to patients At the same time, it also brings greater suffering to the medical staff and affects the postoperative recovery status of patients. There are devices for drainage in the prior art, which also solves the problem of dealing with the effusion after drainage, but it cannot achieve the goal of successful one-time drainage, and the operation process is uncontrollable, which affects the accuracy of drainage, and there will be incidental wounds , thereby prolonging postoperative...
