Bladder calculus removing lens with lockable calculus crushing end

Abstract

The invention relates to a bladder lithotripsy mirror with a closed lithotripsy end, which comprises an outer mirror sheath and a mirror body. The outer mirror sheath is provided with a rotating sheath and an inner mirror sheath. The rotating sheath can be rotatably sleeved outside the endoscope sheath, and rotate There will be no axial relative displacement between the sheath and the endoscope sheath; a calculus pick-up assembly is provided at the end of the endoscope sheath away from the scope body, and an opening is provided on the side wall of the stone pick-up assembly, which can be covered by a sealing assembly, and the inner An instrument channel tube is arranged in the cavity of the mirror sheath, and the stone-crushing component is arranged in the instrument channel tube, and the stone-crushing end extends into the stone-picking component. The bladder stone removal mirror of the present invention can limit stones in a closed space, and stone residues will not enter the bladder during lithotripsy, and there will be no stone residue after surgery, causing less damage to the bladder mucosa, bladder wall and surrounding tissues, and During the lithotripsy process, the stones are always clamped by the elastic framework and will not move at will, 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 instruments, in particular to a bladder stone removal mirror with a sealable stone crushing end. 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...

Problems solved by technology

Since the existing lithotripsy techniques are carried out in relatively open spaces in the bladder, for patients with complications such as bladder diverticulum, stone debris often remains 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 is not easy to be the first choice for the treatment of bladder stones due to the large trauma
