Closed ultrasonic composite lithotripsy device

Abstract

The invention discloses a closed ultrasonic composite lithotripsy device comprising an elastic fan-shaped grabbing claw, a lithotripsy rod, a grabbing sheath tube and a supporting sheath tube; the lithotripsy rod is shaped like a hollow rod; the elastic fan-shaped grabbing claw has an open state and a closed state, and the operating end of the elastic fan-shaped grabbing claw is hinged with the supporting sheath tube and the grabbing sheath tube; the grabbing sheath tube can drive the elastic fan-shaped grabbing claw to be switched between the open state and the closed state; and when the elastic fan-shaped grabbing claw is in the closed state, a closed spherical crushing chamber can be formed, the lithotripsy rod can axially move along the grabbing sheath tube, the lithotripsy end of thelithotripsy rod can extend into the spherical crushing chamber to crush broken stone, and broken stone particles can be discharged from the spherical crushing chamber via a discharging hole in the supporting sheath tube by virtue of a gap between the grabbing sheath tube and the supporting sheath tube. The lithotripsy device is capable of providing a closed lithotripsy space, preventing broken stone particles from generating postoperative damage on health tissues of human bodies and relieving the pain of a patient and beneficial to quick recovery after an operation of the patient.

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...
