Abstract

The invention discloses a catheter cap for a ureteroscope and a ureteroscope catheter with the catheter cap. The catheter cap comprises a catheter cap sleeve, wherein the catheter cap sleeve comprisesa cylindrical sleeve section and a solid cylindrical section coaxial with the cylindrical sleeve section, and an axial flushing channel is formed in the solid cylindrical section in the axial direction. A lateral flushing channel is formed between the axial flushing channel and the outer wall of the solid cylindrical section, and the included angle between the axis of the axial flushing channel and the axis of the lateral flushing channel is an acute angle. When the ureteroscope catheter structure cooperates with a ureteroscope sheath for calculus breaking and removing treatment, injected water can directly act on broken calculi, the broken calculi can fall off from an affected part, the broken calculi can be effectively discharged out of a body, the operation efficiency is improved, andbesides, pain of a patient is relieved.

Description

technical field [0001] The invention relates to the technical field of urological surgery equipment, in particular to a catheter cap for a ureteroscope catheter and a ureteroscope catheter with the catheter cap. Background technique [0002] In flexible ureteroscopic surgery, the flexible ureteroscope can enter the body through the urethra to observe the lesion and can cooperate with surgical instruments to perform visual surgery in the body. Clinical internal examination and visual surgical treatment require endoscopes with clear images to help doctors improve the accuracy of diagnosis. The existing ureteroscopic catheter for flexible ureteroscopic surgery is inserted into the endoscope and after entering the human body, the field of view of the endoscope is kept clear by injecting water. During the lithotripsy operation, the water passing through the ureteroscope can only inject water to the front of the catheter, and cannot directly act on the lithotripsy site, which is ...
