Abstract
The utility model discloses the silicon stents that one kind can block bronchus lumen completely, comprising: the closure branch, side branch and the main branch that are integrally formed and are interconnected, it blocks branch, side branch and main branch and constitutes Y-piece shape silicon stent, wherein block the distal end sealing of branch together.The utility model is by sealing together the closure branch distal end of Y-piece shape silicon stent, after bronchoscope places the utility model silicon stent, bronchus lumen can be blocked by blocking branch, silicone plug rack has plugging effect reliable, it is hardly damaged, complication is lighter, it takes out and is easy, the advantages that can placing for a long time, it can be used for treating bronchopleural fistula, intractable is spat blood (through internal medicine, blood vessel intervention or surgery are handled invalid or should not be used), other airway fistulas, it even can be used for internal medicine lung volume reduction etc., it is curative for effect, in treatment bronchopleural fistula, intractable hemoptysis etc. has certain characteristic and advantage.
Description
Technical field
The utility model relates to a kind of Medical racks, particularly relate to a kind of silicon stent that can block bronchial tube completely.
Background technique
Bronchopleural fistula is clinical very intractable disease, blocks chest by bronchoscope transcatheter bronchus lumen
Membrane cavity and bronchial traffic are the main means for the treatment of；Equally, if lung's intractable hemoptysis internal medicine conservative treatment is invalid, blood
It, can also be through the proximal bronchus of bronchoscope transcatheter bleeding part when pipe is intervened or surgical operation is invalid or should not use
Lumen achievees the purpose that hemostasis.The country only has metallic support, there is no non-metal frame.
Although bronchus lumen can be blocked by placing metal plug rack through bronchoscope, narrow air flue is supported, it is domestic
Existing metal plug rack does not have production licence, and needs to customize in advance, and the diversified in specifications of customization is suitble to calmly, therefore clinical
It is larger to tracheal mucosa irritation using difficulty, and after metallic support is placed for a long time, lead to Mucosal inflammatory damage, hyperplasia, then
Make air flue restenosis.
Utility model content
There is provided the purpose of the utility model is to overcome the deficiencies in the prior art one kind is hardly damaged, complication is relatively light,
Take out the silicon stent that can block bronchus lumen completely that is easy, can place for a long time.
In order to achieve the above objectives, the solution of the utility model is:
A kind of silicon stent that can block bronchus lumen completely comprising be integrally formed and interconnected closure branch,
Side branch and main branch block branch, side branch and main branch and constitute Y-piece shape silicon stent, wherein block the distal end sealing of branch
Together.
Preferably, being respectively arranged with multiple anti-skid bulges on the periphery wall for blocking branch, side branch and main branch.
Preferably, being arranged with support ring on described at least one periphery for blocking branch, side branch and main branch.
Preferably, the bracket ring set above and is therewith close in closure branch, side branch and main branch at least one of,
5 millimeters of bracket ring width, with a thickness of 1 to 1.5 millimeter.
Preferably, the distal end for blocking branch forms closure part, which is triangle, arc-shaped, linear
Or any one in oblique line shape.
After adopting the above scheme, the utility model can block the silicon stent of bronchus lumen by by Y-piece shape completely
The closure branch distal end sealing of silicon stent together, after bronchoscope places the utility model silicon stent, blocks branch
Can block bronchus lumen, silicone plug rack have plugging effect is reliable, be hardly damaged, complication is relatively light, take out be easy,
The advantages that can placing for a long time, can be used for treating bronchopleural fistula, intractable hemoptysis (is handled through internal medicine, blood vessel intervention or surgery
It is invalid or should not use), other airway fistulas, or even can be used for internal medicine lung volume reduction etc., it is curative for effect, in treatment bronchopleural
Fistula, intractable hemoptysis etc. have certain characteristic and advantage.

Specific embodiment
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
As shown in Figures 1 to 6, the utility model discloses a kind of silicon stent that can block bronchus lumen completely,
Including closure branch 1, side branch 2 and the main branch 3 for being integrally formed and being interconnected, blocks branch 1, side branch 2 and main branch 3 and constitute Y type
Tubulose silicon stent, wherein block the distal end sealing of branch 1 together.
It is easy displacement in order to avoid the utility model is put into after bronchus, it is described to block the outer of branch 1, side branch 2 and main branch 3
Multiple anti-skid bulges 12,21,31 are respectively arranged on peripheral wall.
As shown in Figure 1, the distal end for blocking branch 1 forms closure part 11A, closure part 11A is oblique line shape.
As shown in Fig. 2, the distal end for blocking branch 1 forms closure part 11B, closure part 11B is triangle.
As shown in figure 3, the distal end for blocking branch 1 forms closure part 11C, closure part 11C is linear.
As shown in figure 4, the distal end for blocking branch 1 forms closure part 11D, closure part 11D is arc-shaped.
As shown in figure 5, to fit closely the utility model silicon stent with bronchus tube wall, the closure branch 1, side point
It is arranged with support ring 5 at least one periphery of branch 2 and main branch 3, expands the outer diameter of silicon stent, institute by support ring 5
It states support ring 5 and is a tight fit in described at least one periphery for blocking branch 1, side branch 2 and main branch 3, the outer diameter of support ring 5 can
It is 5 millimeters, with a thickness of 1 to 1.5 millimeter, the outer diameter for blocking branch 1, side branch 2 and main branch 3 is equal to or slightly greater than 5mm, makes
Support ring 5 and Y-piece shape silicon stent form tight fit.Bracket changes 5 visual concrete conditions and is dismounted, as shown in the figure, in master
Support ring 5 is equipped in branch 3 and closure branch 1.
The utility model can block the silicon stent of bronchus lumen by by the closure branch of Y-piece shape silicon stent completely
Distal end seals together, and after bronchoscope places the utility model silicon stent, bronchial tube can be blocked by blocking branch
Chamber, silicone plug rack have plugging effect is reliable, be hardly damaged, complication is relatively light, take out be easy, can place for a long time etc. it is excellent
Point can be used for treating bronchopleural fistula, intractable hemoptysis (is handled invalid or should not be adopted through internal medicine, blood vessel intervention or surgery
With), other airway fistulas, or even can be used for internal medicine lung volume reduction etc., it is curative for effect, in treatment bronchopleural fistula, intractable hemoptysis
Deng with certain characteristic and advantage.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
