Embodiment

[0024] This embodiment provides a new type of plugging stone removal catheter, such as figure 1 and figure 2 As shown, it includes a catheter 1 made of medical plastic or dry glue, and the two ends of the catheter 1 are provided with a first plug 11 and a second plug 12 for sealing the catheter 1, and the catheter 1 is close to the first plug 11 One end is provided with the inflatable air bag 13 that material is medical rubber or natural rubber latex. The first plug 11 and the conduit 1 may be integrally constructed. The inflation balloon 13 is inflated eccentrically, and the surface of the catheter 1 is colored; the position of the catheter 1 close to the second plug 12 is marked with a scale.

[0025] This embodiment also includes a screw injector 2. The screw injector 2 includes a handle 21, a screw 22 connected to the handle 21, a fixing part 23 threaded with the screw 22, fixed on the fixing part 23 and the The piston rod 24 connected with the screw rod 22, the piston...

Abstract

The invention discloses a novel blocking type calculus removing catheter. The novel blocking type calculus removing catheter comprises a catheter body, wherein a first plug and a second plug used for sealing the catheter body are arranged at the two ends of the catheter body, and an expansion airbag is arranged at the end, close to the first plug, of the catheter body. The unexpanded expansion airbag is stretched into the near end of a ureter behind calculi firstly, then liquid is injected into the catheter body precisely through a spiral injector, the expansion airbag is precisely expanded to an ideal radius according to the scale marks of the spiral injector based on preopreative examination to block the near end of the ureter so that calculi can be prevented from escaping, and scale marks are arranged at the tail end of the catheter body so that the depth of the catheter body can be observed clearly; the expansion air bag expands in the eccentric direction, the surface of the catheter body is coated with color so that the expansion direction of the expansion airbag can be identified conveniently, and ureteroscopic lithotripsy is not affected after setting is successful. The novel blocking type calculus removing catheter is simple in structure, convenient to use, low in application cost and capable of reducing surgery cost for patients greatly.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a novel blocked stone removal catheter. Background technique [0002] In the operation of crushing stones in the ureter, in order to prevent stone fragments from continuing to penetrate into the human body, some medical instruments for blocking and removing stones are used to extend behind the stones to block the stones. [0003] At present, there are many defects in the medical devices for blocking and removing stones on the market, as follows: [0004] COOK Stone Catcher: The mesh basket made of memory alloy is opened eccentrically behind the stone to achieve the effect of blocking the proximal end of the ureter. The price is expensive at ￥4558, and the memory alloy is soft and the size is fixed. When it is opened behind the stone, it may not be able to completely block the expanded ureter at the rear. During the flushing process, the soft memory alloy basket may be deformed, ca...
