Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable soft ureteral catheter. Background technique [0002] When diagnosing and treating the urinary tract of the urinary system, the ureteral endoscope can visually inspect the difficult-to-inspect parts such as the ureter, renal pelvis, and renal calyx; The incision can significantly reduce the damage to the tissue, thereby speeding up the recovery of the body, shortening the course of treatment, and improving the curative effect, so its use is becoming more and more popular. [0003] Chinese utility model patent CN 201782744U discloses a flexible and rigid combined flexible steering endoscope. Outside the tube, the steering handle controls the flexing of the hose. In clinical use, the catheter part enters the urinary tract of the human body, and then the flexible tube is bent by the handle to complete the inspection or treatment. Although the flexible and hard combined...
