Intracavitary ultrasonic lithotripsy device

Abstract

The invention relates to an intracavity ultrasonic lithotripsy device, which comprises an outer mirror sheath and a mirror body. The outer mirror sheath is provided with a rotating sheath and an endoscope sheath. There will be no axial relative displacement between the mirror sheaths; the end of the endoscope sheath away from the mirror body is provided with a stone picking assembly, and an opening is also provided on the side wall of the stone picking assembly, and the opening can be covered by a sealing assembly. An instrument channel tube is arranged in the cavity, and the crushed stone component is arranged in the instrument channel tube, and its crushed stone end extends into the stone picking component. The intracavity ultrasonic lithotripsy device of the present invention can confine stones in a closed space, and stone residues will not enter the body during stone crushing operation, and there is no stone residue after operation, causing less damage to surrounding tissues, and the stones are crushed The debris interferes less with the endoscopic field of view, can significantly improve the efficiency and effect of the operation, and significantly reduce the pain and burden of the patient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an intracavity ultrasonic lithotripsy device. Background technique [0002] Stone disease mostly occurs in the urinary system and biliary system, and is a common and frequently-occurring disease. It is mainly treated by extracorporeal shock wave lithotripsy (ESWL), endoscopic stone extraction and open surgery. Because extracorporeal shock wave lithotripsy is affected by various interference factors, including the patient's physique, stone quantity, location, activity, and whether it adheres to surrounding tissues, etc., the scope of use and the effect of lithotripsy are greatly reduced. Clinical studies have shown that although extracorporeal shock wave lithotripsy has the characteristics of non-invasiveness and repeated strong operations, repeated lithotripsy on one part often leads to adhesion of stones and surrounding tissues, which must be resolved by open surgery...

AI Technical Summary

Problems solved by technology

However, at present, endoscopic stone removal often has the following disadvantages: 1. Larger single stones need to be crushed and removed in stages, and the visual field is disturbed, unclear, and stone debris remains during the stone removal process, which may cause recurrence of stones after surgery , surrounding tissue damage and other complications

2. For multiple stones, the above disadvantages are more obvious, and the operation time is significantly prolonged due to low stone removal efficiency, unclear visual field interference, and residual stones, and the stone removal effect is not good, which increases the risk of surgery and anesthesia, so it has to be changed. For open surgery, increase the trauma and pain of the patient
