Abstract
The invention discloses a bionic tracheal stent mounted in a trachea. The bionic tracheal stent comprises a stent body. The portion, corresponding to a cricothyroid membrane of the trachea, of the stent body is of a non-closed structure. The bionic tracheal stent has the advantages that the non-closed structure is arranged at the portion, corresponding to the cricothyroid membrane of the trachea of a human body, of the stent body, an arc-shaped structure made of a soft material is produced or two ends of the stent body extend in a staggered mode to enable the tracheal stent to form a helical structure, and the arc-shaped structure or the helical stent bends towards the interior of the stent body to reduce stress effect when the trachea is squeezed to contract, so that diameter change of the tracheal stent is limited, fatigue breakage of the stent due to stress contraction is reduced, and service life of the tracheal stent is prolonged.
Description
Technical field
The present invention relates to a kind of biomimetic scaffolds, particularly one and be arranged on endotracheal bionical trachea bracket.
Background technology
nullExisting support is all nickel-titanium alloy material integral weaving or engraving，Transverse section is cylinder-like structure，If the most circumferentially stress point is uniform，That whole support entirety when radial compression is shunk can extend，Fatigue strength can meet the demand of Clinical practice effect duration (such as esophagus、Intestinal、Biliary tract rack etc.)，But the physiological anatomic architecture according to trachea，It is one layer of ring first film inside it，There is the about 3/4 cricoid cartilage cladding enclosed outside，Trachea is when being shunk by the extruding of esophagus when taking food or cough is shunk，The diameter of cricoid cartilage is no variation in contraction，Only ring first film produces in the part not having cricoid cartilage to be coated with and shrinks，And during cylinder stent generation crimp，It it not overall elongated，And border is to diminish such state with overall outside diameter，But lateral compression power can be received，And cricoid cartilage simply limits the change of stent diameter，Support is made to become crescent from circular (full moon shape)，It bends with the cradle portion branch of the EDGE CONTACT of cricoid cartilage，Produce the STRESS VARIATION being perpendicular to tangential direction，So that support produces fatigue fracture.
Summary of the invention
Goal of the invention: the technical problem to be solved is for the deficiencies in the prior art, it is provided that one is arranged on endotracheal bionical trachea bracket.
In order to solve above-mentioned technical problem, the invention discloses one and be arranged on endotracheal bionical trachea bracket, including rack body, the part of described rack body correspondence annulus trachealis first film is non-occluded configuration.
In the present invention, the part of rack body correspondence annulus trachealis first film is for being provided with non-occluded configuration opening, and the two ends of opening are connected by soft connection support.
In the present invention, the two ends of described rack body opening are sewed up with the soft employing hinge type that is connected between support.
In the present invention, the part of rack body correspondence annulus trachealis first film is the interior soft support mutually staggered and outer soft support, thus the non-occluded configuration described in constituting.
In the present invention, described outer soft support is positioned at the periphery of soft support.
Beneficial effect: the present invention is arranged to the structure of non-closed at person's windpipe ring first film corresponding part, soft material is used to make arcuate structure or make trachea bracket form helical structure at rack body two ends staggered extension, when trachea receives extruding contraction, arcuate structure or helical stent bend in rack body, reduce stress effect, thus limit the change of trachea bracket diameter, reduce support stress and shrink the fatigue fracture produced, extend the service life of trachea bracket.
Accompanying drawing explanation
Being the present invention with detailed description of the invention below in conjunction with the accompanying drawings and further illustrate, the above-mentioned or otherwise advantage of the present invention will become apparent.
Fig. 1 is the front view of the present invention；
Fig. 2 is the generalized section of arcuate structure support；
Fig. 3 is the generalized section of helical structure support.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
Such as Fig. 1, the present invention includes rack body 1, and the part of the corresponding annulus trachealis first film of rack body 1 is non-occluded configuration 2 opening, and wherein rack body 1 and non-occluded configuration 2 use hinge type to sew up.Specifically, such as Fig. 2, wherein rack body 1 is 3/4 type non-closed annular support, soft connection support 2a correspondence annulus trachealis first film part, can bend to the position of 2b or 2c inside rack body 1 when being under pressure.
Such as Fig. 3, including rack body 1, interior soft support 3a and outer soft support 3b, interior soft support 3a is connected to rack body one end and extends internally, outer soft support 3b is connected to rack body 1 other end and stretches out and mutually stagger with interior soft support 3a, and described rack body 1, interior soft support 3a and outer soft support 3b constitute helical structure.
The present invention is in use, this bionical trachea bracket is placed in tracheal strips fix, non-occluded configuration is made to correspond to the ring first film position on trachea, trachea on the feed or cough time can produce extruding and shrink, when the soft connection support that non-occluded configuration is arcuate structure, when support receives extruding and shrinks, the soft connection support of arcuate structure can be under pressure and curve inwardly, when non-occluded configuration is two soft supports that rack body two ends extend out and mutually stagger, when constituting helical stent with rack body, when support receives extruding and shrinks, the interior soft support being connected on rack body and outer soft support form one with rack body, curve inwardly contraction simultaneously, support is avoided to produce fatigue fracture.
The invention provides one and be arranged on endotracheal bionical trachea bracket; the method and the approach that implement this technical scheme are a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.Each ingredient the clearest and the most definite in the present embodiment all can use prior art to be realized.
