Abstract
The utility model discloses a self-expanding type artificial bio-valve, which is composed of an elastic Ni-Ti alloy pipe grid type structure and an artificial bio-valve; the artificial bio-valve fissure is arranged in the Ni-Ti alloy pipe grid type structure is a stitching way. The Ni-Ti alloy pipe grid type structure used in the utility model has an excellent compression-expansion function, after being overlapped with the artificial bio-valve, the structure can be compressed into the blood vessel cavity and naturally spreads in the blood vessel to act the function of spreading and fixing the artificial bio-valve. By adopting the self-expanding type artificial bio-valve of the utility model, the blood shortage injuries caused by blood flow cutoff and the wound caused by extracorporeal circulation can be avoided, the utility model has the advantages that the implanting process of the valve becomes simple and fast, the operation risk is reduced, the operation safety is enhanced, the wound of the patient is reduced, and the economic burden of the patient is lightened; the technical requirements for the medical staff and the equipment requirements for operation are reduced; the medical treatment range is enlarged. The utility model has a good market application prospect.
Description
Technical field
This utility model relates to a kind of self-expanding formula bioprosthesis valve, belongs to technical field of medical instruments.
Background technology
At present, the bioprosthesis valve implant surgery is a kind of important means of treatment cardiovascular disease.Because the particularity of bioprosthesis valve implant surgery, its operating time are long and complicated operation.The mode of existing this operation of clinical practice is the blocking-up vascular flow, cuts blood vessel wall, and bioprosthesis valve is sewed up implantation or under the condition of extracorporeal circulation of blood, cut blood vessel wall, sews up implantable artificial biovalve etc.Above-mentioned existing modus operandi all has very high requirement to medical worker's technology and equipment, has bigger risk and damage concerning the patient, is prone to ischemic injuries as the blocking-up vascular flow; Extracorporeal blood follows body damage etc.
Therefore, be badly in need of a kind of easy and simple to handle, operation risk is low, body damage is little, with low cost bioprosthesis valve at present to remedy the deficiencies in the prior art.
Summary of the invention
The purpose of this utility model is, a kind of operation technique of being convenient to is provided, and can reduce the self-expanding formula bioprosthesis valve of operation risk and body damage.
For achieving the above object, this utility model adopts following technical scheme:
A kind of self-expanding formula bioprosthesis valve is characterized in that it is made up of rubber-like Nitinol tubular mesh shape structure and bioprosthesis valve; This bioprosthesis valve seam places in this Nitinol tubular mesh shape structure.
Above-mentioned self-expanding formula bioprosthesis valve, wherein, it is latticed that the tube wall of described NiTi gold tubular mesh shape structure is evenly distributed, the quantity of grid can according to joining bioprosthesis valve size and decide.
Above-mentioned self-expanding formula bioprosthesis valve, wherein, the internal diameter of described Nitinol tubular mesh shape structure is 10～30mm.
Above-mentioned self-expanding formula bioprosthesis valve, wherein, the length of described Nitinol tubular mesh shape structure is 10～30mm.
Above-mentioned self-expanding formula bioprosthesis valve, wherein, the internal diameter of this bioprosthesis valve is 8～28mm.
Above-mentioned self-expanding formula bioprosthesis valve, wherein, the external diameter of this bioprosthesis valve is 11～31mm.
Above-mentioned self-expanding formula bioprosthesis valve, wherein, the length of this bioprosthesis valve is 10～30mm.
Above-mentioned self-expanding formula bioprosthesis valve, wherein, described bioprosthesis valve is to utilize the stitching linear slit to place in this Nitinol tubular mesh shape structure.
Bioprosthesis valve described in the utility model is ripe medical material, obtains easily.
Advantage of the present utility model and benefit:
The used latticed Nitinol tubular mesh shape structure of this utility model has good compression-expansion function, can be compressed after being laminated with bioprosthesis valve and import in the lumen of vessels, it launches in blood vessel naturally, play and launch and the fixedly effect of bioprosthesis valve, compared with prior art, use self-expanding formula bioprosthesis valve described in the utility model and can make the implant sewing process of the operation simple and fast that becomes, simplified the operating procedure of operation, shortened the time of operation, further reduced when improving operation efficient because the operation risk that bloodstream blocking and extracorporeal circulation cause, improved the safety of operation, reduced patient's wound, reduce the cost of operation, alleviated patient's financial burden; Requirement and apparatus for medical worker's surgical technic require to reduce, thereby have enlarged range of operation, have good application prospects.
