[0002] Ureteroscopy is a medical device used for urological treatment. It is a slender instrument composed of a light-guiding fiber, a working cavity and various working accessories for different purposes. The use of ureteroscopes to diagnose and treat ureteral diseases can greatly improve the diagnosis and treatment level of ureteral diseases and shorten the patient's hospitalization time.

[0003] Ureteroscopic or rigid ureteroscopes are often used in urological surgery for examination or lithotripsy. In order to maintain a clear field of vision and flush out broken stones in time, surgical assistants need to repeatedly use a 50 ml syringe with an extension tube for injection (manual pressurized pulse). This operation is very inconvenient and requires frequent cooperation between doctors and nurses, which can easily affect the doctor's concentration during the examination.
