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
The present invention relates to medical instruments field, particularly stone conduit is got in the novel shutoff of one.
Background technology
In the operation of ureteral broken calculus, continuing to go deep into human body for preventing stone debris, extending into after calculus by the medical apparatus and instruments adopting some shutoff to get stone, shutoff is carried out to calculus.
At present, the medical apparatus and instruments that stone is got in the shutoff on market also exists many defects, as described below:
COOK calculus grabber: the made basket of memorial alloy is opened in calculus rear eccentricity, realizes shutoff ureter near-end effect.Expensive, and memorial alloy is partially soft, and size is fixed, and when calculus rear is opened, may not necessarily block rear expansion ureter completely, and in water-rinsing process, the soft memorial alloy basket distortion of possible deflection, causes stone debris to be escaped.
Stone conduit is got in the made shutoff of Shanghai Ying Nuowei company, at calculus rear, forms fold blade so that shutoff ureter near-end with sheet distortion.Price your $2828 partially, and centered by this shutoff blade, property is opened, and occupies ureter middle position, affect rubble operation, and plugging effect is unsatisfied with, there is comparatively wide arc gap between ureter wall and shutoff blade, calculus is easily escaped from this gap.
Medical molecular material can be injected ureteral calculus rear by external report, and frozen plug ureter near-end reaches plugging effect voluntarily, dissolves this solidification material again after rubble by cold water flush.This valuable product, not easily promotes the use of.

Detailed description of the invention
Hereafter will describe the present invention in detail in conjunction with specific embodiments.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they can mutually be combined thus be reached better technique effect.
Embodiment
The present embodiment provides a kind of novel shutoff to get stone conduit, as depicted in figs. 1 and 2, comprise the conduit 1 that material is medical plastic or dry glue, described conduit 1 two ends are provided with the first plug 11 and the second plug 12 for sealing duct 1, and described conduit 1 is provided with near first plug 11 one end the swelling gasbag 13 that material is medical grade rubber or Heveatex.Described first plug 11 can be Construction integration with conduit 1.Described swelling gasbag 13 is eccentric to expansion, and conduit 1 surface scribbles color; Described conduit 1 indicates scale near the position of the second plug 12.
