Ischesis is that an impact is treated in clinicalThe subject matter of effect.
The second is silicon stent, and its feature is: be 1. not easy to place, 2. support wall thickness internal diameter is little, 3. can take out,4. easily cause ischesis, 5. domestic expensive at present. This support is not easy to place, support wall thickness internal diameter is little,Easily cause the more problems such as ischesis, this support price is at home very expensive at present in addition.
The third is Dynamic support, and this support is invented by German doctor Freitag, and its feature is: 1. veryBe not easy to place, 2. the moderate internal diameter of cradle wall is moderate, 3. can take out, 4. the soft movable air flue that contributes to of support rear wallSecretion is discharged, 5. domestic current without this product. The problem of this support maximum be place very difficult, limited itsClinical application.
Air flue Y type support, owing to being positioned over bulge region, so general stationarity is fine, can not be shifted. But YType support has two distinct issues: first y-type structure, than monotubular support complexity, is relatively difficult to place; It two isY-type structure has covered left and right main bronchus and part tracheae, therefore very large on the discharge impact of airway secretions. AndAbove-mentioned three kinds of Y type supports sum up: although the metal film coated support of the first self-expansion type is easily placed, easily leadCause ischesis; The second silicon stent had both been not easy to place, and easily caused again ischesis; The thirdAlthough Dynamic support contributes to airway secretions to discharge, be very difficult to place. Therefore, existing support all withoutMethod solves two subject matters that current Y type support faces.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of easy placement and be not easy again to cause the Y of ischesisThe metal film coated airway stent of type.
For achieving the above object, the present invention by the following technical solutions: the metal film coated airway stent of a kind of Y type, comprisesOne skeleton and that is " Y " shape tubular structure overlays on the membrane structure on described skeleton outer wall, and described skeleton comprises a main boneFrame and two is arranged on branch's skeleton of described main framing one end, it is characterized in that: the front at described main framing arranges oneAlong the axially extended breach of main framing.
Described skeleton is formed by the braiding of niti-shaped memorial alloy silk material.
Described membrane structure exceeds the end 1～1.5mm of described main framing; Described membrane structure exceeds the end of described branch skeleton1～the 1.5mm of portion.
The end of the end of described main framing and branch's skeleton described in each adopts closing-in structure.
Be positioned at end on described main framing than the little 0.5～1mm of the diameter of described main framing; Be positioned on described branch skeletonEnd than the little 0.5～1mm of diameter of described branch skeleton.
Described membrane structure adopts pellosil.
The width of described breach occupy described main framing girth 1/3.
The present invention is owing to taking above technical scheme, and it has the following advantages: 1, the present invention is being Y " shape tubular structureThe front of main framing on an axially extended breach along main framing is set, and be covered with film at the outer surface of skeletonStructure, so airway stent of the present invention is put into after air flue bulge region, breach laminating tracheae rear wall, again because after tracheaeWall is the soft structure supporting without cartilage, therefore can promote airway secretions by the motion of the membrane structure of indentation, thereDischarge. 2, the present invention is because skeleton is formed by the braiding of niti-shaped memorial alloy silk material, and therefore, airway stent is being putBefore entering air flue, can radially flatten, air flue to be inserted removes external force later, the inflatable original shape that returns to of airway stentShape, makes airway stent be easy to insert patient's air flue. 3, the present invention due to membrane structure exceed the end 1 of skeleton～1.5mm, therefore can reduce the stimulation of airway stent end to tunica mucosa tracheae, thereby prevent granulation tissue hyperplasia. 4,The present invention, because each end of skeleton all adopts closing-in structure, therefore can prevent from stimulating tracheal wall to produce granulation tissue. ThisInvention is a kind of comparatively desirable Y type airway stent, has practical value and promotional value.
