Ureteroscope urinary bladder pressure reducing device

Abstract

The invention relates to a ureteroscope urinary bladder pressure reducing device. The pressure reducing device comprises an outer sheath and an inner core; the inner core is arranged in the outer sheath; the far end of the inner core extends out of the outer sheath; the near end of the inner core is clamped on the end portion of the outer sheath; a telescopic device is arranged at the far end of the outer sheath; a base is arranged at the near end of the outer sheath; a side pipe is arranged on the base; a regulator is connected to the side pipe; a clamping groove is formed in the regulator; the two ends of the telescopic device are closed up towards the middle to form a protrusion when the telescopic device is in a contraction state; the outline face of the protrusion is an arc-shaped face. The ureteroscope urinary bladder pressure reducing device has the advantages that the pressure reducing of the urinary bladder is achieved through the modes that liquid in the urinary bladder is released through the outer sheath, and meanwhile the opening and the closing of a liquid outlet is controlled through the regulator, repeat mirror returning is not needed, and the facts that the pressure in the urinary bladder is too high or the injure of the urinary bladder occurs caused by the continuous increase of the liquid in the urinary bladder are avoided; the inner core controls the contraction and the recovery of the telescopic device, the operation is simple, and the minimally invasive injure is small; the inner core is arranged in the outer sheath in a penetrating mode before and after an operation, dredging and guiding functions are achieved, and the outer sheath can be prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a ureteroscope bladder decompression device. Background technique [0002] Ureteroscopy is an extension of urethroscopy and cystoscopy in the upper urinary tract. Ureteroscopy refers to putting endoscopes through the urethra through the bladder and other natural human passages for biopsy of ureters and kidneys, lithotripsy, electrocautery and ureteroscopy. Various operations such as narrow internal incision make full use of the natural cavity of the human body for some surgical operations, avoiding the need to make a large incision in the abdomen in traditional operations. It is mainly used to treat stones, polyps or strictures in the middle and lower ureter, and can also be used to diagnose diseases such as renal pelvis and ureteral tumors. [0003] Ureteroscopy has been around for more than half a century. Its advantage is to examine and treat diseases through the ...
