[0025] In this embodiment, an optical fiber is installed in the catheter 3, and a gap is provided between the optical fiber and the catheter 3. The end of the catheter 3 away from the three-way connector 1 is a gradual structure, and the through hole 4 is located at the end of the catheter 3 away from the three-way connector 1. During the operation, the catheter 3 is inserted into the surgical nephroscope, and there is a certain gap between the catheter 3 and the surgical nephroscope. During operation, the gap between the catheter 3 and the surgical nephroscope is supplied with water by positive pressure, which can play a good cooling effect. At the same time, a part of the broken stones are discharged through the gap between the optical fiber and the catheter 3. Multiple through holes 4 can prevent the catheter 3 from being blocked.

[0026] One end of the fixed connector is connected with an optical fiber end cap.
