Abstract
The utility model provides a kind of bionical trachea bracket, including main airway holder part, right main branch airway holder part and left main branch airway holder part, the main airway holder part, right main branch airway holder part and left main branch airway holder part form trifid structure.The main airway holder part is semi-circular structure, including cambered surface portion and planar portions.As a result of integral memory alloy braided support, while meet bionics principle, the leak stopping of support is with better function, is less susceptible to make tracheae perforate, bleeding, the symptom such as ulcer.Because biomimetic scaffolds reduce the stimulation to tissue, patient acutely coughs probability reduction, and the life-span of support will also significantly improve therewith.
Description
Technical field
Area of medical devices is the utility model is related to, particularly a kind of bionical trachea bracket of memorial alloy integral weaving.
Background technology
At present for the tracheostenosis caused by treatment advanced lung cancer, vertical diaphragm and esophageal tumor cause tube chamber external pressure narrow and
The big whole body of patient grade is in poor shape, which not to tolerate operator, need to generally insert trachea bracket, conventional bracket be generally straight cylinder type or
The Y type trachea brackets being made up of three sections of straight cylinders, although solving the problems, such as stent migration, because the main tracheae of human body is configured to D
Type cartilage structure, traditional cylinder cause excessive stimulation to cartilage portion, cause patient ceaselessly acutely to cough all the time, this
And support is caused to be easily broken off the major reason to fail.
Utility model content
Purpose of utility model：Technical problem to be solved in the utility model is in view of the shortcomings of the prior art, there is provided one
The bionical trachea bracket of kind.
In order to solve the above-mentioned technical problem, the utility model provides a kind of bionical trachea bracket, including main airway support
Part and the right main branch airway holder part below main airway holder part and left main branch airway holder part, the master
Airway stent part, right main branch airway holder part and left main branch airway holder part form trifid structure.
In the utility model, the main airway holder part is semi-circular structure, and semi-circular structure includes cambered surface portion peace
Face.The annular cartilage that cambered surface portion corresponds to person's windpipe is set, and the ring first film that planar portions correspond to person's windpipe is set.
In the utility model, the cross section of the right main branch airway holder part is circle.
In the utility model, the cross section of the left main branch airway holder part is circle.
In the utility model, the length of the right main branch airway holder part is more than the length of left main branch airway holder part
Degree.
In the utility model, support material is titanium-nickel wire.
In the utility model, the main airway holder part, right main branch airway holder part and left main branch airway cradle portion
Point the braiding path change for connecting through titanium-nickel wire link into an integrated entity structure.
In the utility model, the main airway holder part, right main branch airway holder part and left main branch airway cradle portion
The junction divided is flexible coupling with PTFE flexible cords.
Beneficial effect：As a result of integral memory alloy braided support, while meet bionics principle, the leak stopping of support
It is with better function, it is less susceptible to make tracheae perforate, bleeding, the symptom such as ulcer.Because biomimetic scaffolds reduce the stimulation to tissue, patient
Acutely cough probability is reduced, and the life-span of support will also significantly improve therewith.
Brief description of the drawings
The utility model is done with reference to the accompanying drawings and detailed description and further illustrated, the utility model
Above-mentioned or otherwise advantage will become apparent.
Fig. 1 is the structural representation of embodiment；
Fig. 2 is sectional view at A-A in Fig. 1；
Fig. 3 is the structural representation of embodiment.
Embodiment
The utility model is elaborated below in conjunction with accompanying drawing.
Embodiment：
Such as Fig. 1, a kind of bionical trachea bracket shown in the present embodiment, including main airway holder part 1, right main branch airway branch
Frame part 2 and left main branch airway holder part 3.
It is the sectional view on Fig. 1 at A-A such as Fig. 2, main airway holder part generally semi-circular structure, cross section D
Shape, main airway holder part include cambered surface portion 5 and planar portions 4.Meet person's windpipe construction, tracheae is not caused to extrude, be applicable
Property is strong.
Such as Fig. 3, the cross section of right main branch airway holder part is circle, and the cross section of left main branch airway holder part is circle
Shape.
The shape of the support of the present embodiment, angle and size all meet Human physiology construction, right main branch airway support
Partial length is more than the length of left main branch airway holder part, positions, makes in right main branch airway and left main branch airway respectively
Main airway D types shape will not be misplaced, will not rotate, will not overturn, and is bonded the tracheae construction of human body main airway D types completely.Simultaneously
There is the positioning of Y types, support is not easy to shift.
The braiding of whole support is completed by a titanium-nickel wire braiding.
The braiding path change that connects through of support three parts carries out soft company using at Hard link or segmentation with PTFE flexible cords
Connect, can so ensure that integral support does not only have good compliance and bio-imitability, while also can guarantee that support there are enough branch
Support force.
The bionical tracheae silicon stent of contrast tradition, the bionical D-Y types rami tracheales of memorial alloy integral weaving of the present utility model
Frame not only has bionical effect, while can be fitted into smaller device for posting and discharge.
The utility model provides a kind of bionical trachea bracket, and it is many to implement method and the approach of the technical scheme,
Described above is only preferred embodiment of the present utility model, it is noted that is come for those skilled in the art
Say, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as the scope of protection of the utility model.The available prior art of each part being not known in the present embodiment is realized.
