Clinical in vivo examination and visual surgical treatment require a sharp image endoscope to help the doctor improve the accuracy of diagnosis. The medical endoscope is a detection and treatment instrument integrating optics, electricity, precision machinery and software into a whole, and is provided with an image transmission assembly, an optical or electronic imaging module, a cold light source or an LED electronic light source, a mechanical device and the like, and the medical endoscope can enter the body through a natural pore canal and can see pathological changes which cannot be displayed by X rays and ultrasound, so the medical endoscope is very useful for improving the medical quality, and many diseases need to be examined, diagnosed and treated through the endoscope, such as diseases at trachea, esophagus, stomach, intestine, bladder and the like. Endoscopic lithotripsy is performed by inserting an endoscope with a diameter of about 3mm into a ureter through urethra and bladder, and breaking up ureteral calculus or renal calculus. It utilizes the natural urinary system cavity of human body, does not make any incision on the human body, and is a pure urinary surgery endoscopic minimally invasive surgery.
In the calculus removing operation, the flexible endoscope can enter the body through the urethra to observe the lesion part and can be matched with a surgical instrument to carry out visual operation treatment in the body. In the existing cystoscope operation, a cystoscope is generally used for observing and treating an affected part, when a ureter needs to be checked or treated, a ureteroscope needs to be inserted again, a ureteroscope catheter is inserted into a ureter sheath to treat the affected part, in the broken calculus removing operation process, broken calculus which is hit by holmium laser needs to be discharged out of a body through the ureter sheath, at the moment, the ureteroscope catheter needs to be withdrawn for operation, but the discharge condition of the broken calculus cannot be observed due to the withdrawal of the ureteroscope catheter, so that the broken calculus cannot be completely discharged out of the body at one time, in order to ensure the operation effect, the ureteroscope catheter needs to be inserted for observation or treatment for multiple times, so that the pain of a patient is increased due to repeated operation of inserting the ureteroscope catheter, and meanwhile, the injury of organs of the human body is easily caused.
