[0002] When using endoscopes such as flexible ureteroscopes for the treatment of ureteral obstruction or stones in clinical practice, they are usually used in conjunction with a sheath tube that serves as a channel and an endoscopic catheter. When in use, the endoscopic catheter is inserted into the lumen of the sheath tube, and the operator holds the handle at the tail of the endoscopic catheter to operate it. The endoscopic catheter needs to be repeatedly advanced and retreated in the lumen of the sheath tube dozens or even hundreds of times. Not only is the endoscopic catheter with a length of nearly 1 meter easily contaminated by microorganisms or other harmful particles in the environment when it withdraws from the lumen of the sheath tube, but the contaminated endoscopic catheter will cause infection and other injuries after re-entering the body. In addition, the operator needs to hold the handle connected to the tail of the endoscopic catheter for a long time, and the unguided suspended operation can easily lead to a decrease in operating accuracy and frequent operating errors after finger fatigue, especially causing the laser to be released incorrectly and damage the urinary system mucosa. At the same time, the slender laser optical fiber, guide wire, etc. used in laser lithotripsy are inserted into the working channel of the endoscopic catheter by the operator, and the operation steps are cumbersome. During the operation, the laser optical fiber, guide wire, etc. are easily contaminated by the environment. Summary of the invention
