Frame, including outer layer, middle layer and internal layer, the outer layer and internal layer are the tissue that average float is less than or equal to 2, and the middle layer is
Average float is more than 2 tissue, and the outer layer, middle layer and internal layer form tubing by stitch weave and wefting insertion, described
Middle layer and internal layer circumferential cross-section in O-shaped, the outer layer circumferential cross-section is C-shaped, it is axially spaced several circumferential passageways are distributed with,
The circumferential passageway of the outer layer is protruded with intermediate layer separation, and the circumferential passageway of the outer layer is double width fabric construction.
The back warp stitch weave structure that itself stitch weave between the outer layer, middle layer and internal layer connects under being.
Two circumferential passageways are distributed on the trachea bracket in an axial direction.
The outer layer and internal layer are weaved using monofilament, and the middle layer is weaved using multifilament.
Advantageous effect
Overall structure of the present invention is uniform and stable, has excellent radial support power and good elastic recovery, can be
The regeneration of tracheae diseased region and the support that offer abundance is provided;Circumferential cross-section of the present invention is C-shaped, axially spaced-apart distribution is circumferential logical
The structure in road is conducive to the placement of tracheal rings, can provide good structure base for the reparation and establishment of tracheal rings
Plinth;The present invention realizes the integrated weaving in trachea bracket three-layer pipe road, is suitable for continuous production.

Specific implementation mode
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, people in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
A kind of used in tissue engineering biomimetic type trachea bracket as shown in Figure 1, including outer layer 1, middle layer 2 and internal layer 3.Outer layer
1 selects 1/2 twill-weave, as shown in Fig. 2, outer layer 1 is used as using the PDO monofilament of a diameter of 0.2mm weaves material.Middle layer 2
1/5 twill-weave is selected, is woven as shown in figure 3, middle layer 2 uses specification to be used as the PHBV/PLA multifilament of 160dtex/72f
Material.Internal layer 3 selects 2/1 twill-weave, as shown in figure 4, internal layer 3 is used as using the PDO monofilament of a diameter of 0.2mm weaves material
Material.
The internal diameter of the trachea bracket is 15mm, and breadth is designed as 32.5mm on the machine of tubing, other set factors are such as
Shown in the following table 1.
The weaving parameters of 1 trachea bracket of table
Outer layer 1, middle layer 2 and internal layer 3 combine " by outer and interior " again by the back warp tying method binding of " under connect "
