Background

Electronic ureteral endoscopy is an important part of urinary surgery, is a modern main treatment mode in the aspect of treating kidney stones and ureteral upper end stones, and thoroughly changes the surgical treatment mode of the traditional open surgery. The electronic ureter endoscope operation is a channel established by the electronic ureter endoscope through a ureter sheath, enters the kidney, and simultaneously provides an instrument channel, so that surgical instruments (e.g. a stone-taking basket and a laser optical fiber) can conveniently enter the electronic ureter endoscope for treatment. In use, the electronic ureter endoscope is divided into disposable use and repeated use, and the repeated use has the risk of disinfection and cross infection; after the surgical instrument enters the existing disposable electronic ureteroscope, a great amount of bending angles are lost, so that the bending angles are insufficient in the surgical process, and the position of kidney stones cannot be successfully reached for treatment during treatment.
