Road only sets one；And support it is embedded when stimulate bigger, and the support force fixed if reducing and stimulating can be smaller,
Stent is caused to slide.
The content of the invention
The purpose of the present invention is in view of the deficienciess of the prior art, a kind of breathing of offer is smooth, support force is relatively strong and pierces
Swash less 3D printing trachea bracket.
Technical solution：It is of the present invention solve the problems, such as used by technical solution be：A kind of 3D printing trachea bracket, including internal layer
Stent and outer stent；The inner stent and outer stent is disposed as circular stent, and the outer stent
Outside diameter is more than inner stent, and the thickness of the inner stent is then more than outer stent, and the inner stent and outer layer
It is connected between stent by equally distributed supporting rod；Center tracheae is arranged at the center of the inner stent, and it is described
Inner stent and outer stent between gap be arranged to auxiliary tracheae；And the outer surface of the outer stent is additionally provided with
Equally distributed raised support；Stomata is additionally provided with the inner stent；The stomata is uniformly distributed, and the gas
Hole is disposed as arcuate structure.
Preferably, the supporting rod set between the inner stent and outer stent sets six altogether；It is and described
Supporting rod is uniformly distributed；And the height of the supporting rod is arranged to 1-3mm.
Preferably, the stomata in the inner stent is provided with six altogether, described six stomata intervals are uniformly set
Put, and the supporting rod set between the stomata and ectonexine stent is to be staggered.
Preferably, the outside diameter of the inner stent is arranged to the half of the outside diameter of outer stent；And the outer layer branch
The thickness of frame is arranged to the half of inner stent thickness.
Preferably, the raised support outside the outer stent can be set to equally distributed dots structure either
The linear structure axially uniformly extended along outer stent around the circular ring structure of outer stent is either around outer layer branch
The helical structure on frame surface；The thickness of the raised support is arranged to 0.5mm.
Beneficial effect：Compared with prior art, the present invention has the following advantages：Trachea bracket is provided with two altogether in the present invention
Layer, the inside center hole setting center tracheae of inner stent；And the gap among ectonexine stent is equally applicable to the auxiliary of breathing
Tracheae is helped to use；In addition it is exactly to also set up stomata in the inside of internal stent, on the one hand can mitigates overall weight and materials；
On the other hand increase respiration channel；And exterior supporting structure may be provided with a variety of, helical form, spot distribution in the present invention,
Linear or circular structure, the external support of different structure are adapted to different medical symptom, and these structures
Firm degree of support it is all relatively strong, and possess the characteristics of forced area is small, the stimulation degree of tracheae can be greatly reduced, make
With conveniently.
