Problems solved by technology

2) The narrow inner diameter of the ureter increases the technical requirements of the flexible ureteroscope, which increases the price of the flexible ureteroscope and is easily damaged. The direct consequence increases the cost of the technology and limits the development of the technology
3) The operating channel of the flexible ureteroscope is narrow, and the channel is occupied by the lithotripsy fiber during the lithotripsy process, resulting in various consequences caused by blocked water flow: kidney damage caused by increased pressure, retrograde infection, accidental injury caused by unclear vision, and reduced lithotripsy efficiency , extended operating time, limited total operating time, etc.
[0006] The shortcoming of this invention is that the difference between the middle section and the upper section of the ureter and the lower section ureter is ignored in the anatomical structure. Under the same air or water pressure and action time, the dilation effect of the lower ureter is different from that of the upper and middle ureter

Abstract

The invention relates to a three-balloon ureteral liquid-gas expansion pipeline suite. The three-balloon ureteral liquid-gas expansion pipeline suite comprises a ureteral catheter, wherein a tip drainage channel opening is formed in one end of the ureteral catheter, and an upper balloon, a spacing balloon and a lower balloon are sequentially arranged on the side, close to the tip drainage channel opening, of the ureteral catheter in a spacing manner; a first channel, a second channel, a third channel, a fourth channel, a fifth channel and a sixth channel are sequentially arranged at one end, far away from the upper balloon, of the ureteral catheter; and a first opening and a second opening are formed in one side of the ureteral catheter. The ureter is divided into two cavity gaps through the upper balloon, the spacing balloon and the lower balloon, and liquid or gas is injected into the two cavity gaps through the first opening and the second opening; and the liquid pressure and the acting time of the two cavity gaps are different, so that expansion with the basically same effect is achieved on the premise that different sections of ureters are dissected and the dilated capacities are different at a time.

Description

technical field [0001] The invention relates to the technical field of ureteroscopic surgical treatment, in particular to a three-balloon ureteral liquid-pneumatic expansion pipeline set. 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 ureteroscopy technology and the prom...
