Abstract
The utility model provides a bronchus trunk twig branching type inner support which characterized in that: the inner support is whole to be little y shape, and constitute including straight tube form trunk support with from the branching support that the trunk support was told, and branch the support diameter and be less than the trunk support, the contained angle of branching support and trunk support is 20 - 70, the inner support can also can design tectorial membrane support or partial tectorial membrane for naked support. The beneficial effects of the utility model are that: 1, single wire rod uses the support of single weaving manner preparation, and the holding power is better, 2, comparing with big Y type support, more according with the anatomical structure in the human bronchial tree, the inner wall is said in the chamber of laminating better, reduces the angulation and to the stimulation of air flue, 3, the manufacture craft is uncomplicated, does not have the like product both at home and abroad, the sexual valence relative altitude, and the application is broad.
Description
Technical field
This utility model relates to Medical rack, be for expand human body bronchus treatment bronchial stenosis or shutoff bronchial fistula stomatosis become the support making it unobstructed, be also that one more meets bronchus anatomical structure inner airway stent.
Background technology
Often run in clinical bronchus cicatricial stenosis, softening or malignant tissue infiltration, oppress the bronchial stenosis caused, and the disease such as esophagobronchial fistula, thoracic cavity rami gastrici tracheal fistula that various advanced tumor is formed, serious threat human body is healthy, the ventilatory function of obvious restriction patient, even threat to life.Because patient's body constitution is poor, cannot surgical operation be carried out, and support is inserted and effectively can not only be alleviated rapidly dyspnea, shutoff fistula mouth, improves the quality of living, and won the time for treatment further.But in clinical practice, existing various support is better for trachea pathological changes therapeutic effect, but all has problems for bronchus pathological changes, as simple Y type support, between its support angle and bronchus, easy angulation, causes granulation tissue to breed, and causes support intracavity restenosis.After inserting common airway stent, support poor compliance, often there is symptom of coughing in patient, and occurs expectoration difficulties, and even support two ends restenosis, severe patient can threaten patient vitals.
The defect of above-mentioned common trachea bracket significantly limit the application of endotracheal stent in bronchial stenosis and fistula treatment.
Summary of the invention
The purpose of this utility model is just for problem existing for above-mentioned prior art, the defect that the poor compliance of rear appearance, patient's foreign body sensation are strong, the easy angulation of support causes granulation to breed is inserted in order to overcome common trachea bracket, and custom-designed a kind of good adherent effect that has, be applicable to the main stem bronchus branching type inner support for the treatment of bronchial stenosis and various bronchial fistula.
The purpose of this utility model is achieved through the following technical solutions: a kind of main stem bronchus twig branching type inner support, overall in little y shape, comprise straight tube-like trunk support and prop up from the branching that trunk support separates and be configured to, and branching stent diameter is less than trunk support.
In this utility model, the angle of branching support and trunk support is at 20 °-70 °.
Described inner support can be bare bracket, also can design ret rievable steots or part overlay film frame.
Described inner support is have elasticity or/and the single wire rod integral braiding of shape memory characteristic forms, Stent silk only has an engagement head, the globality of inner support is adapted to the various change of bronchial shape, and support fastness is better, also not easily loosens during taking-up.
The material forming support can be alloy material (comprising rustless steel, nitinol alloy wire), macromolecular material (as polyethylene, polyurethanes, politef) or degradation material (PPDO, polylactic acid, polyglycolic acid etc.).
Described covering material is medical polyurethane, politef, silicone rubber, dacron membrane or polyethylene, ePTFE thin film, weaving PET film.
It is that stay-supported is loosened release with lower carriage that support of the present invention is released to branching portion support and trunk portion branching, and trunk portion branching is above is that propelling movement type discharges, and mode of movement is substantially identical with the mode of movement of existing large Y type support.
The beneficial effects of the utility model:
1, single wire rod uses the support that single weaving manner makes, support force and fastness better; 2, compared with large Y type support, more meet the intrabronchial anatomical structure of human body, tract inwall of fitting better, reduce angulation and the stimulation to air flue; 3, processing technology is more simple and convenient, and comparatively import support is lower for price, and cost performance is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of inner support of the present invention.
In figure: 1. trunk holder part, 2, branching holder part.
detailed description of the invention,
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in Figure 1: a kind of main stem bronchus twig branching type inner support, overall is little y shape, comprises straight tube-like trunk support 1 and forms from the branching support 2 that trunk support separates, and branching support 2 diameter is less than trunk support 1, and angle is at about 45 ° between the two.
Trunk support 1 and branching support 2 are all formed by single yarn woven, and more firm in the process of inserting and taking out, not easily loosen, support force is better.
The occupation mode of main stem bronchus twig branching type inner support of the present utility model is as follows:
Before using, branching and trunk portion branching are first bundled on the core pipe of Y type stent conveying device head end with lower carriage by doctor, trunk compression is placed on carrier, in use procedure, guided by seal wire, under the Lookout assist effect of x-ray or endoscope, support is delivered to diseased region and discharges, wherein branch portion support at superior lobar branches tracheal strips, trunk portion branches with upper bracket on the main bronchus of left and right, trunk portion branches with lower carriage in right leaf bronchus or bronchus lobaris inferior sinister, support is fixed on intraluminal lesion exactly, support lashing wire is extracted at bracket conveyer tail end, release branching portion support and trunk portion branching are with lower carriage, finally discharge carrier epitheca, release trunk portion branching is with upper bracket, support is made again to recover shape gradually and expand to strut tube chamber, and tube wall of well fitting.
