Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of apparatus for the treatment of the narrow and fistula of the non-blood vessel tract of human body, specifically a kind of non-blood vessel covered stent that prevents complication.
Background technology
At present, at esophagus and similarly to insert the narrow and fistula of stent in the treatment in the human body organ be a kind of effective method for treatment, it has, and wound is little, patient is painful little, the characteristics that surgery cost is low, be particularly useful for inoperable gerontal patient, can significantly improve patient's living condition.
In order to treat the narrow of body cavities, people have invented the support of different shape.But all there is multiple complications in they,, displacement hemorrhage, generation restenosis etc. as easy generation, and influencing therapeutic effect has also increased the financial burden that patient treats again simultaneously.A large amount of clinical examples show that the position that restenosis takes place is in the two ends of support, and incidence rate is up to 37%～94%.
Summary of the invention
The purpose of this utility model is the problem of complication such as the easy generation that exists at the non-blood vessel orifice bracket of existing treatment is hemorrhage, displacement, designs a kind of non-blood vessel covered stent that prevents complication.
The technical solution of the utility model is:
A kind of non-blood vessel covered stent that prevents complication, comprise the latticed rack body 1 of one or more interconnective columniform nitinol alloy wires, two ends that it is characterized in that this rack body 1 positioning end 2 of external diameter that all be connected smoothly greater than rack body 1 external diameter, on rack body 1 surface, be provided with anti-skidding protruding 3, the silica gel thin film 4 that all is coated with one deck silica gel thin film 4 and positioning end 2 on the positioning end 2 at described rack body 1 and its two ends stretches out and forms a softish silica gel thin film edge outside the positioning end 2, to reduce of the stimulation of support two ends to body cavities, thereby reduce the probability that restenosis takes place, whether needs take out in patient's body according to support, described anti-skidding protruding 3 or cover in the silica gel thin film 4 (so that taking-up), or expose outside silica gel thin film 4, so that incarceration is in the mucosa of organ pipe wall.
Described positioning end 2 or be cup-shaped, or be spherical, or be trumpet type, the shape of the location 2 of two ends can be identical, also can difference.
Described anti-skidding protruding 3 can be split-type structural with rack body 1, and the two links to each other by the nitinol alloy wire stitch.
Described anti-skidding protruding 3 with rack body 1 also can be monolithic construction.
In the rack body 1 relative with described anti-skidding protruding 3 inner support 5 can be installed, inner support 5 passes through the nitinol alloy wire stitch in rack body 1.
Described anti-skidding protruding 3 or be that successive projection is at rack body 1 lip-deep annular protrusion, or for being positioned at discrete point-like projection on rack body 1 surface.
The size of mesh opening of described rack body 1 to reduce radial support power, stimulates outgrowth possibility thereby reduce less than the size of mesh opening of the positioning end of its two end.
When described rack body 1 is made up of two or more, link to each other by connecting line 6 between the described rack body 1.
The utlity model has following advantage:
1, easy to operate, can use existing laying method that this product is placed in patient's the body.
2, common support at two ends not overlay film reach skidproof effect, but can bring the outgrowth side reaction in two ends simultaneously.This utility model increases annular projection and does not cover pellosil by the middle part at support, and the silk material incarceration that makes support has significant skidproof effect in esophageal mucosa membrane injury; Increase the inner support of overlay film simultaneously, prevent the restenosis that tube chamber endogenous cause of ill hypertrophy or tumor growth cause.
3, utilize the variation of bracket end preparation method, the radial support power of the end of support is reduced, stimulate outgrowth possibility thereby reduce.
4. make full use of the softish characteristics of silica gel thin film, reduced of the stimulation of support two ends, thereby reduce restenosis body cavities.
