Abstract

The invention relates to the technical field of medical surgical instruments, in particular to a flexible ureteroscope. The flexible ureteroscope comprises an operating handle, a shifting piece for controlling the bending direction and angle of the flexible ureteroscope is arranged on the operating handle, the shifting piece is rotatably connected to the operating handle, an angle indicating device is arranged on the operating handle, and the angle indicating device is positioned on one side of the shifting piece. The angle indicating device is arranged on the operating handle, the shifting piece is adjusted to enable a pointer to correspond to different numerical values on the angle indicating device, the bending state of the in-vivo flexible ureteroscope can be obtained according to data of the in-vitro flexible ureteroscope, so that operation and learning of the flexible ureteroscope are executed according to data and quantitative standards, the convenience in the operation process is improved, the operation difficulty is reduced, and a learning curve of the flexible ureteroscope operation is shortened.

Description

technical field [0001] The invention relates to the technical field of medical surgical instruments, in particular to a flexible ureteroscope. Background technique [0002] Flexible ureteroscopy in the treatment of urinary calculi, due to the flexibility of the mirror body, can directly reach the renal pelvis and calyces through the urethra, with less trauma, less complications, and avoids the risks of kidney damage and bleeding. Compared with percutaneous nephrolithotripsy, it is more effective for Kidney stones with a diameter of less than 2 cm have obvious advantages. As a new lithotripsy device, flexible ureteroscope is more and more widely used in clinic. [0003] However, the existing flexible ureteroscope cannot judge the bending degree of the front end of the flexible ureteroscope inserted into the body during the operation, so it can only be learned and operated by experience and hand feeling, which will cause great inconvenience to the operation and make the opera...
