Abstract

The utility model relates to a coronary stent, which comprises a plurality of metal main body units. Adjacent metal main body units are mutually connected via connecting parts to form a pipe wall annular stent, each connecting part consists of two S-shaped structures, the two S-shaped structures are in I-shaped arrangement, adjacent ends of the two S-shaped structures are connected mutually, and free ends of the two S-shaped structures are respectively connected with the adjacent metal main body units. Because each connecting part consisting of the two S-shaped structures which are in I-shaped arrangement is large in extension space, the coronary stent effectively increases supporting force and flexibility, improves expansion property and is favorable for clinic application.

Description

Coronary artery bracket

Technical field

This utility model relates to the medical instruments field technology, refers in particular to a kind of coronary artery bracket.

Background technology

The coronary artery bracket technology is that interventional therapy method is hindered by a kind of coronary artery Wicresoft, it is in the treatment of coronary heart disease, can implant coronary artery bracket in the coronary artery place of infraction, make blood continue to flow, become Therapeutic Method the most effective and commonly used at present gradually, this coronary artery bracket has more and more received much concern since clinical practice.Coronary artery bracket requires very high technically, and clinical material to support requires very strict, not only extremely thin, requires quite firm simultaneously.Tradition coronary artery bracket system is connected to form the barrel ring support by a plurality of metal masters by connecting rod, yet, the tradition connecting rod is to adopt linear structure, or " v " or " n " or " s " shape structure, aspects such as its support force, compliance and dilatancy exist not enough, bring influence can for clinical final result, be unfavorable for marketing.

The utility model content

This utility model is at the existing disappearance of above-mentioned prior art, and main purpose is to provide a kind of coronary artery bracket, can effectively improve support force and compliance, and improve spreading performance, helps clinical practice.

For realizing above-mentioned purpose, this utility model is taked following technical scheme:

A kind of coronary artery bracket, comprise a plurality of metal masters unit, the adjacent metal main unit is interconnected by connector and constitutes the tube wall ring support, described connector is made up of two S type structures, this two S type structure is in-line and arranges, and the abutting end of this two S type structure is connected to each other, and the free end of this two S type structure is connected with the adjacent metal main unit respectively.

Described metal master unary system is connected as a single entity by a plurality of segmental arcs, and this segmental arc is provided with inner concave and outer convex surface, and the free end by two S type structures between the two outer convex surfaces of adjacent metal main unit connects.

Described metal master unary system is connected as a single entity by a plurality of segmental arcs, and this segmental arc is provided with inner concave and outer convex surface, and the free end by two S type structures between two inner concaves of adjacent metal main unit connects.

Described metal master unary system is connected as a single entity by a plurality of segmental arcs, and this segmental arc is provided with inner concave and outer convex surface, and the free end by two S type structures between the inner concave of adjacent metal main unit and the outer convex surface is connected.

The connector that this utility model advantage is to form by two S type structures of in-line arrangement makes extendable room big the adjacent metal main unit, can improve support force and compliance effectively, and improve spreading performance, helps clinical practice.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment this utility model is further described.

As Fig. 1, be this utility model first embodiment; A kind of coronary artery bracket comprises a plurality of metal masters unit 10, and adjacent metal main unit 10 is interconnected by connector 20 and constitutes the tube wall ring support, wherein:

Described metal master unit 10 is to be connected as a single entity by a plurality of segmental arcs 11, and this segmental arc 11 is provided with inner concave 11a and

outer convex surface

11b, 10 liang of outer convex surface 11b of adjacent metal main unit can be over against, can also be oblique staggering, do not add at this and give restriction.

Described connector 20 is made up of two S type structures 21, and this two S type structure 21 is in-line arranges, and the abutting end of this two S type structure 21 is connected to each other, and the free end of this two S type structure 21 is respectively between the two outer convex surface 11b of adjacent metal main unit.By this, can effectively uphold by this two S type structure 21a.

As Fig. 2, be this utility model second embodiment; A kind of coronary artery bracket comprises a plurality of metal masters unit 10, and adjacent metal main unit 10 is interconnected by connector 20 and constitutes the tube wall ring support, wherein:

outer convex surface

11b, 10 liang of inner concave 11a of adjacent metal main unit can be over against, can also be oblique staggering, do not add at this and give restriction.

Described connector 20 is made up of two S type structures 21, and this two S type structure 21 is in-line arranges, and the abutting end of this two S type structure 21 is connected to each other, and the free end of this two S type structure 21 is respectively between the two inner concave 11a of adjacent metal main unit.By this, can effectively uphold by this two S type structure 21a.

As Fig. 3, be this utility model the 3rd embodiment; A kind of coronary artery bracket comprises a plurality of metal masters unit 10, and adjacent metal main unit 10 is interconnected by connector 20 and constitutes the tube wall ring support, wherein:

Described metal master unit 10 is to be connected as a single entity by a plurality of segmental arcs 11, and this segmental arc 11 is provided with inner concave 11a and outer convex surface 11b, and inner concave 11a and outer convex surface 11b did not add at this and to give restriction over against, perhaps oblique staggering in the adjacent metal main unit 10.

Described connector 20 is made up of two S type structures 21, and this two S type structure 21 is in-line arranges, and the abutting end of this two S type structure 21 is connected to each other, and the free end by two S type structures 21 between the inner concave 11a of adjacent metal main unit 10 and the outer convex surface 11b is connected.

Present embodiment only is that with the foregoing description difference segmental arc 11 correspondence positions are different in the metal master unit 10, and its function is identical, does not add at this and gives restriction.

The connector that this utility model design focal point is to form by two S type structures of in-line arrangement makes extendable room big the adjacent metal main unit, can improve support force and compliance effectively, and improve spreading performance, helps clinical practice.

The above, it only is the preferred embodiment of this utility model structure, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
