Abstract
The utility model relates to an artery intracavity stent which is mainly used for repairing vascular lesions, belonging to a medical appliance that can be implanted into the human body. The artery intracavity stent mainly comprises a single main stent and three branch stents with different lengths. The artery intracavity stent is applicable to repairing artery lesion of branch parts.
Description
Technical field
This utility model relates to a kind of being mainly used in and repairs arterial vascular lumen of artery inner support, belongs to the medical device of human implantable.
Background technology
At present, in the treatment of arterial disease,, often adopt the interior interventional method of lumen of artery to treat, be about to the lumen of artery inner support and send into the arterial disease position, in lumen of artery, rebuild arterial wall, recover normal blood flow especially for pathological changes such as hemangioma, artery dissections.Along with the application extension to the lumen of artery inner support, beginning adopts the branching type support to carry out the reparation of aortic arch pathological changes in operation on aorta.Three branches of the branching type lumen of artery inner support of using are contour structure substantially at present, and in actual operation is used, because the blood supply position of corresponding tremulous pulse has nothing in common with each other, different ramose implantation modes difference to some extent during operation technique, thereby contour branch support can not satisfy the needs of clinical practice, even may cause the difficulty of operation.For improving the suitability of branching type support, three branch's support Design need be not contour structure, so that satisfy instructions for use better.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of lumen of artery inner support rational in infrastructure, with satisfy three branch's supports in inserting process to the ramose length requirement of difference, reduce the risk of treatment, improve the applicability of branching type support.
The lumen of artery inner support that this utility model is designed is mainly propped up by single trunk support and three branches and is configured to, and the surface of support is covered with film or fabric, and three branch's supports are along trunk support axially-aligned, and each is unequal for length.
In this utility model, branch's support along the axial position deviation of trunk support between 0 °～30 °.
In this utility model, the length of medial fascicle support is less than the length of dual-side position branch support, and difference is between 1mm～20mm.
In this utility model, the length of a side position branch support is greater than the length of another side position branch support, and difference is between 1mm～20mm.
This utility model is when using, and the medial fascicle of three branch's supports is the shortest, when implanting pairing left common carotid artery, can reduce this tremulous pulse is carried out free scope, is convenient to blocking-up.Position, the limit branch support of three branch's supports is long slightly, helps the fixing of support, according to pairing left subclavian artery and the innominate artery length before the bifurcated not, selects the length of different edge position support.By control to different branches stent length, both guaranteed the fixed safety of support, limit range of operation again, reduce the treatment risk, thereby the reliability and security of three branch's stent applications is improved.
The advantage of the lumen of artery inner support that this utility model is designed is:
1. suitably reduce by three branches support medial fascicles and implant the length of left common carotid artery, can corresponding minimizing to the free scope of the dissection of left common carotid artery, shorten operating time, reduce tissue injury, be convenient to support simultaneously and insert;
2. the sufficient length that keeps three branch's bracket lip position supports, the firm performance of raising integral support, the safety that reinforced support is used.
Description of drawings
Accompanying drawing is a kind of lumen of artery inner support structure chart of the present utility model: the middle limit of 1-length position branch support, and the 2-medial fascicle, length is the shortest, position, the limit branch support that 3-length is the longest, 4-trunk support.
The specific embodiment
Lumen of artery inner support as shown in drawings, prop up by single trunk support 4 and three branches and to be configured to, the surface of support is covered with film or fabric, three branch's supports are along trunk support axially-aligned, branch's support is 10 ° along the axial position deviation of trunk support, the length of medial fascicle support 2 is 5mm less than the length of position, limit branch support 1, and position, limit branch support 3 is 5mm greater than the length of position, limit branch support 1.The length of branch's support 2 is convenient to support and is inserted left common carotid artery, the length of branch's support 3 helps support and is fixed in left subclavian artery, the length of branch's support 1 is suitable for support to be inserted and is fixed in innominate artery, thereby improves the reliability and the safety of integral support.
The foregoing description is that concrete scheme of the present utility model is given an example, and protection domain is limit according to claim.
Claims (4)
1. lumen of artery inner support is mainly propped up by single trunk support and three branches and is configured to, and the surface of support is covered with film or fabric, it is characterized in that: three branch's supports are along trunk support axially-aligned, and each is unequal for length.
2. lumen of artery inner support according to claim 1, its feature also is: branch's support along the axial position deviation of trunk support between 0 °～30 °.
