The invention relates to a double-balloon three-channel ureteral dilation pipeline kit and a use method thereof. The double-balloon three-channel ureteral dilation pipeline kit comprises a ureteral catheter and a guide wire, a first balloon is arranged at one end of the ureteral catheter, and a second balloon is arranged on the side, away from the first balloon, of the ureteral catheter. A first channel, a second channel and a third channel are sequentially arranged at the end, away from the first balloon, of the ureteral catheter, the first channel is communicated with the first balloon, the second channel is communicated with the second balloon, an opening is formed in the side face of the ureteral catheter and located between the first balloon and the second balloon, and the third channel is communicated with the second balloon. The opening is communicated with the third channel; a first joint is arranged at the top end of the balloon I; a second joint is arranged at the top end of the guide wire; the first connector and the second connector are detachably connected. According to the ureteral catheter, the number of kidney drainage channels is reduced, the independently-packaged whisker-shaped guide wire is additionally arranged, the overall circumferential diameter of the catheter is reduced, and the ureteral catheter can be conveniently placed into the ureter through the guide wire.
Description
technical field [0001] The invention relates to the technical field of ureteroscopic surgical treatment, in particular to a double-balloon three-channel ureteral dilatation conduit set and a method of use thereof. Background technique [0002] Compared with rigid ureteroscopes, flexible ureteroscopes have a flexible function, and can treat ureteral calculi and upper ureteral stones that travel up the ureter to the kidney during lithotripsy. More and more patients are treated with flexible ureteroscopes. For kidney stones with indications for surgical stone removal, percutaneous nephrolithotomy was the absolute mainstream for a long time before the development of flexible ureteroscopy technology and technology. Compared with percutaneous nephrolithotomy, flexible ureteroscopic lithotripsy does not require renal puncture, so there is no risk of puncture expansion and renal hemorrhage when the mirror body is moved during lithotripsy. With the improvement of flexible ureterosco...
