Abstract
The present invention provides a combined bracket which relates to a medical inner bracket of a lumen of a human body and comprises a support bracket and a protective sleeve. Because the jacket type structures of the support bracket and the protective sleeve are adopted, the support strength of the support bracket is uniformly dispersed on a protective net and a protective film of the protective sleeve; the stimulation of metal wires, particularly the metal wires on both ends of the support bracket to lumen mucous membranes is decreased. Granulation growth is effectively prevented, and the present invention is particularly suitable for good disease changes, for example, the narrow temporary dilatation or the permanent dilatation of a stoma. The present invention has the obvious advantages of simple operation, good positioning and definite therapeutic effects and is convenient to take out and not easy to slide.
Description
Technical field
The present invention relates to a kind of medical stent, particularly treat the human body lumen when narrow expandable stent or the stifled fistula support of lumen fistula or operation in the typing bracing frame of lumen when being shaped.
Background technology
In the prior art, when diseases such as treatment esophageal stricture, biliary tract stenosis, tracheal stenosis, urethral stricture, angiostenosis, arteriovenous fistula, esophago-tracheal fistula, medical stent and overlay film medical stent have been obtained good curative effect, but the part pathological changes is after implanting medical stent, can cause side effect such as granulation hyperplasia, though the overlay film medical stent can stop granulation or tumor tissues penetrating the support mesh to a certain extent, but two ends at overlay film frame, granulation tissue hyperplasia is obvious, seal the two ends of overlay film frame sometimes, cause the restenosis of lumen.This situation for benign lesion particularly the people of cicatrix body constitution when its surgical stapling stenostomy portion implant frame, especially obvious.Existing support still can't solve this difficult problem.
Summary of the invention

---the protective jacket (2) of combinations thereof cribbing has the geometry that is complementary with supporting bracket (1).
The described geometry that is complementary with supporting bracket (1) is the cylinder cast.
The described geometry that is complementary with supporting bracket (1) is single trumpet type.
The described geometry that is complementary with supporting bracket (1) is the double horn type.
---supporting bracket (1) one end of combinations thereof cribbing or an end of protective jacket (2) are installed the recovery ring of being made by terylen silk or tinsel (5).Reclaim in the grid that an end tinsel that ring (5) is through the protection network (3) of supporting bracket (1) or protective jacket (2) forms.
---the supporting bracket (1) and the protection network (3) of combinations thereof cribbing have different weave pattern or laser engraving decorative pattern; The diameter wiry that protection network (3) adopts is littler than the diameter wiry that supporting bracket (1) adopts, the maximum gauge of the mesh of protection network (3) is than the maximum gauge of the mesh of supporting bracket (1), and protection network (3) support force is littler than the support force of supporting bracket (1).Protection network (3) can slow down the stimulation of supporting bracket (1) to the lumen mucosa, and the expansionary force of the tinsel generation of supporting bracket (1) is evenly distributed on the protection network (3).
---the protective jacket (2) of combinations thereof cribbing only is made up of protection network (3), and at this moment protection network (3) is normally used the softness of memorial alloy fibrage and the fine and close metal gauze or the laser engraving net of the ultra-thin pipe of memorial alloy.
---between 15～42 ℃, the diameter of niti-shaped memorial alloy silk is usually between 0.01～0.8mm usually for the supporting bracket (1) of combinations thereof cribbing and the recovery temperature of the niti-shaped memorial alloy that protection network (3) adopts.
---the supporting bracket (1) and the protection network (3) of combinations thereof cribbing adopt other medical elastic material manufacture.
Described other medical elastic materials are rustless steel.
Described other medical elastic materials are titanium alloy.
---the protecting film (4) of combinations thereof cribbing adopts medical grade silicon rubber or polyurethane manufacturing.
The present invention is owing to adopted the sleeve type structure of supporting bracket (1) with protective jacket (2), the support dynamics of supporting bracket (1) is dispersed on the protection network (3) and protecting film (4) of protective jacket (2) uniformly, reduced the tinsel of supporting bracket (1) to greatest extent, particularly the two ends tinsel is to the stimulation of lumen mucosa, prevented the growth of granulation effectively, be particularly suitable for benign lesion, provisional expansion or permanent expansion as anastomotic stricture, have simple to operate, have good positioning, be difficult for to slide, determined curative effect, the obvious advantage of being convenient to take out.
