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] However, the device of this invention has two balloons and four channels, and its structure is rather complicated, which will increase its design and manufacturing process. At the same time, there may also be a problem that the success rate of the "kit" inserted into the ureter may decrease due to the diameter being too thick.

Embodiment 1

[0038] see Figure 1 to Figure 4 , the ureter rapid liquid-pneumatic dilation tubing kit of this embodiment, comprising a first ureteral catheter 10, a second ureteral catheter 20 and a constant pressure water supply device 30;

[0039] One end of the first ureteral catheter 10 is provided with a balloon one 15, and the side of the first ureteral catheter 10 away from the first balloon 15 is provided with a second balloon 16; the first ureteral catheter 10 is far away from the ball One end of capsule one 15 is provided with first passage 11, second passage 12, third passage 13 successively, and described first passage 11 is communicated with described balloon one 15, and described second passage 12 is connected with described balloon two. 16, the side of the ureteral catheter is provided with a first opening 14, the first opening 14 is located between the first balloon 15 and the second balloon 16, the first opening 14 is connected to the third channel 13 communicated; the fi...

Embodiment 2

[0052] see Figure 5 with Image 6 , the difference between the rapid liquid-pneumatic dilatation tubing kit of the ureter of this embodiment and the embodiment is that,

[0053] The peripheral side of described balloon one 15, balloon two 16, balloon three 27 and balloon four 28 is provided with annular raised portion 40; Described annular raised portion 40 and corresponding balloon one 15 or ball Balloon two 16 or balloon three 27 or balloon four 28 communicate; The surface of balloon two 16, balloon three 27 or balloon four 28 is combined into a smooth surface, so that balloon one 15, balloon two 16, balloon three 27 or balloon four 28 can enter the human body more smoothly;

[0054] Specifically, the axial direction of the annular protrusion 40 is parallel to the axial direction of the corresponding first ureteral catheter 10 or the second ureteral catheter 20 .

[0055] When the first balloon 15, the second balloon 16, the third balloon 27 and the fourth balloon 28 of ...

Abstract

The invention relates to a ureteral rapid liquid-gas expansion pipeline suite and a using method thereof. The ureteral rapid liquid-gas expansion pipeline suite comprises a first ureteral catheter and a second ureteral catheter. The ureter is pre-expanded through the first ureteral catheter, the first ureteral catheter is not suitable for remaining in the ureter for a long time due to the fact that a pelvis drainage channel is removed from the first ureteral catheter, the problem that the pressure in the kidney of the working side is increased is solved, and therefore the first ureteral catheter is only prepared for short-time expansion and preliminary expansion of the ureter; and after the diameter of the ureter is increased, the second ureteral catheter can be more conveniently placed for long-time expansion, the expansion time is several hours or ten hours or longer, the ureteral expansion effect and safety are greatly improved, the placing success rate of the second ureteral catheter is increased, then the operation success rate of a flexible ureteroscope is increased, the process requirement and price of the flexible ureteroscope are reduced, the performance of the flexible ureteroscope is improved, the diameter of a water flow channel is increased, and the safety and effect of the flexible ureteroscope are rapidly improved.

Description

technical field [0001] The invention relates to the technical field of flexible ureteroscopic surgical treatment, in particular to a quick liquid-pneumatic expansion pipeline set for the ureter and a method for using the same. 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 flexib...
