Push type bladder diverticulum calculus removing device

Abstract

The invention relates to a push type stone removal device for bladder diverticulum calculi, which comprises a mirror body, one end of the mirror body is connected with a telescopic frame body, the other end of the telescopic frame body is provided with a closing assembly, and the telescopic frame body is covered with an elastic cylindrical film. The frame body and the closing assembly are stretched and closed through the drive assembly, and a lithotripsy assembly and an endoscopic imaging assembly are arranged in the telescopic frame, the lithotripsy assembly is a Di laser lithotripsy assembly, and the lithotripsy assembly includes a laser optical fiber; the propulsion of the present invention The stone extraction device for bladder diverticulum stones can confine the stones in the bladder diverticulum in a closed space. When lithotripsy is performed in this closed space, stone residues will not enter the body, and there will be no stone residue after surgery, and will not damage the surrounding area. The tissue is damaged, and the calculus debris has little interference with the endoscopic field of view, and has little impact on the operation process, which 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 devices, in particular to a stone removal device for push-type bladder diverticulum stones. Background technique [0002] Bladder stones are common diseases of the urinary system, mostly secondary to lower urinary tract obstruction and stones from the kidneys and ureters entering the bladder, especially stones in the lower ureter. Bladder stones can usually be divided into single stones or multiple stones, and their solutions are also different. Surgical treatment methods include endoscopic surgery, open surgery, and extracorporeal shock wave lithotripsy (ESWL). In general, extracorporeal shock wave lithotripsy is not effective due to factors such as greater activity and the special position of the bladder in the pelvis. Small single stones in the bladder can be removed by lithotripsy forceps, laser and other methods, but for large single stones (stone diameter ≥ 3cm) or multiple stones, the ston...

AI Technical Summary

Problems solved by technology

Since existing lithotripsy techniques are performed in relatively open spaces in the bladder, for patients with complications such as bladder diverticulum, stone fragments often remain in the diverticulum, which is not easy to wash out, causing stone recurrence and enlargement. The pain and burden of patients, and bladder stone removal surgery is not suitable as the first choice for the treatment of bladder stones due to the large trauma
