Problems solved by technology

[0005] However, the above-mentioned technical solutions have the following deficiencies. In the first solution, by rotating the rotary joint, the hard sheath can be pushed into the ureter very conveniently until the renal pelvis, and the soft mirror advances axially with the hard sheath. sheath restriction
The second solution is to separate the rigid ureteroscope body and the mirror sheath through the locking mechanism. The sheath is placed in the mirror ureter and can be used as a channel for repeatedly taking broken stones or the mirror body enters and exits the ureter alone. However, the sheath is placed in the lower ureter It is inconvenient to take out the mirror sheath, and the mirror sheath cannot be bent or turned at a large angle
The pump tube used for cleaning in the existing operating equipment lacks a fixing mechanism, and the pump tube is easy to fall off, resulting in leakage of irrigation fluid

Abstract

The invention relates to medical instruments and discloses an upper urinary tract complex lesion percutaneous flexible ureteroscope operation to solve the problems that a flexible tube of an existing ureter device is prone to being left in a lower section of a ureter, a pump line is prone to disengaging, and consequently, body irrigation fluid leaks. According to the upper urinary tract complex lesion percutaneous flexible ureteroscope operation, a percutaneous puncturing and expanding device, a ureteroscope, a cold light source, a camera system, a bedside B ultrasonic machine, an intracavity calculus removing instrument, a high-pressure sacculus expander, a pressure adjusting water-delivery pump and a holmium laser ureteroscope are adopted. The ureteroscope comprises a sheathing canal, a flexible tube located in the sheathing canal, a push tube used for connecting the sheathing canal with the flexible tube, a handheld part located at the tail end of the sheathing canal and a washing valve. By means of the rotationally-combined sheathing canal and flexible tube, the ureteroscope is more suitable for being applied to complex kidney stone operations.

Description

technical field [0001] The invention relates to a medical device, in particular to percutaneous flexible ureteroscopy for complex lesions of the upper urinary tract. Background technique [0002] Upper urinary tract calculi are frequently-occurring diseases in urology. The treatment methods include extracorporeal shock wave lithotripsy, percutaneous nephrolithotomy, and ureteroscopy, each with its own advantages and disadvantages. Among them, percutaneous nephrolithotomy is considered to be the first choice for the treatment of complex stones (stone diameter > 2.5 cm or multiple stones). With the gradual development of various operations, various problems exposed during the operation have further emerged, including residual stones, stones combined with ureteral stenosis, polyps, and failure of mirroring caused by severe tortuosity of the ureter, making it difficult to observe and reach the lesion for treatment, etc. [0003] Patent document 200810197442.4 (application da...
