Push type bladder diverticulum calculus removing device

Abstract

The invention relates to a push type bladder diverticulum calculus removing device. The push type bladder diverticulum calculus removing device comprises a lens body, wherein one end of the lens body is connected with a retractable frame body, a closing assembly is arranged at the other end of the retractable frame body, an elastic cylinder film is sheathed outside the retractable frame body, the retractable frame body and the closing assembly retract and close by virtue of a driving assembly, a calculus crushing assembly and an endoscope imaging assembly are arranged in the retractable frame body, and the calculus crushing assembly is a holmium laser calculus crushing assembly and comprises laser fibers. The push type bladder diverticulum calculus removing device can limit a calculus in a bladder diverticulum in an enclosed space, calculus residue cannot enter into a human body while a calculus crushing operation is carried out in the enclosed space, no calculus residue is produced after operation, and no damage is caused to surrounding tissues; meanwhile, interference of calculus chips to view of an endoscope is smaller, influence on an operation process is small, operation efficiency and an operation result can be obviously improved, and pain and burden of a patient can be obviously alleviated.

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
