Closed Ultrasonic Composite Lithotripsy Device

Abstract

The invention discloses a closed ultrasonic composite lithotripsy device, which comprises: an elastic fan-shaped grasping claw, a stone-breaking rod, a grasping sheath and a supporting sheath; the stone-breaking rod is in the shape of a hollow rod, and the elastic fan-shaped grasping claw has In the open state and the closed state, the operating end of the elastic fan-shaped grasping claw is hinged with the support sheath and the grasping sheath, and the grasping sheath can drive the elastic sector-shaped grasping claw to switch between the open state and the closed state. When the fan-shaped grasping claws are in the closed state, a closed spherical crushing cavity can be formed, the stone crushing rod can move along the axial direction of the grasping sheath, and the crushing stone end of the stone crushing rod can extend into the spherical crushing cavity to crush The broken stones and broken stone particles can be discharged from the spherical crushing chamber through the gap between the grasping sheath and the supporting sheath through the discharge port on the supporting sheath. The lithotripsy device can provide a closed lithotripsy space, avoid postoperative damage to human healthy tissues caused by crushed stone particles, reduce pain of patients, and facilitate rapid postoperative recovery of patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a closed ultrasonic composite lithotripsy device. Background technique [0002] Stone disease mostly occurs in the urinary system and biliary system, and is a common and frequently-occurring disease. At present, the main treatment methods include open surgery, extracorporeal shock wave lithotripsy (ESWL), and endoscopic stone removal. [0003] Open surgery stone removal is mainly used for the surgical treatment of kidney stones. It is a method of removing stones by cutting the renal pelvis, renal parenchyma or ureter. This method is traumatic and slow postoperative recovery. The residual stone rate is high. [0004] Extracorporeal shock wave lithotripsy is a non-invasive and reproducible lithotripsy method that uses shock waves to crush stones in the human body from outside the body into small pieces for easy excretion. Using this method, the crushing rate of stones and...
