Abstract
The invention discloses a kind of coronary vessel stent manufacture method, comprise the following steps: a. forms the multiple support rings cut out the most successively on tubing by the way of cut, and offers groove in the middle part of each support ring；B. the support ring obtained after a step is made annealing treatment, to remove the residual stress produced when described cut；C. utilize Nitinol to be woven into tinsel, and tinsel outer surface plates titanium nitride material screen layer, then make rack, and rack is placed in support ring；D. support ring relevant position is carried out stretch bending, and welding forms wavy thin section successively, and process convex, then use electrochemical polishing machine to be polished, to not having two thin segments to carry out bonding after polishing.The present invention is used to be effectively improved stability and the reliability of coronary vessel stent.
Description
Technical field
The present invention relates to cut field, specifically, be a kind of coronary vessel stent manufacture method.
Background technology
Coronary atherosclerotic heart disease refers to that the blood vessel-coronary artery supplying cardiotrophin material occurs serious
Atherosis (plaque) or spasm, make coronary stricture or obstruction, and form thrombosis, cause obliteration, lead
Cause myocardial ischemia-anoxemia or a kind of heart disease of infraction.The most typically use Percutenous transluminal coro-nary angioplasty
(PTCA) treat, owing to simple coronary artery balloon dilatation (POBA) restenosis rate is high, currently mainly prop up with blood vessel
It is main PTCA Therapeutic Method that frame is got involved, and by expansion intravascular space, recovers the unobstructed of blood flow, and it has, and wound is little, recover
Hurry up, feature that success rate is high.Coronary artery bracket in the market is all based on material characteristics, it is impossible to ensure that support is simultaneously simultaneously
There is good radially support force, compliance and pass through property, therefore, structurally innovating, demand could be met.
Summary of the invention
It is desirable to provide a kind of coronary vessel stent manufacture method, to solve the problems referred to above.
For achieving the above object, technical scheme is as follows:
A kind of coronary vessel stent manufacture method, it is characterised in that comprise the following steps:
A. on tubing, by the way of cut, form the multiple support rings cut out the most successively, and at each
Groove is offered in the middle part of pushing out ring；
B. the support ring obtained after a step is made annealing treatment, should with the remnants that removing produces when described cut
Power；
C. utilize Nitinol to be woven into tinsel, and tinsel outer surface plates titanium nitride material screen layer, then make net
Frame, and rack is placed in support ring；
D. support ring relevant position is carried out stretch bending, and welding forms wavy thin section successively, and process convex, then adopt
It is polished with electrochemical polishing machine, to not having two thin segments to carry out bonding after polishing.
Further, the pipe diameter in described step a is 1mm.
The beneficial effects of the present invention is: the present invention has medicine-carrying trough, have and improve medicine distribution in the blood vessel, increase
Coating adhesive ability on support, the advantage extending the action time of medicine.Carrier unit the most of the present invention is by trough
Bonding, connect in " top is the end of to " so that support list distance diminishes, so that the mesh area of support reduces, add pathological changes
The support force of speckle.
Again, it is provided with fool proof at the crest of thin segment side and connects convex, and connection breach is set at opposite side crest, make
Connect simpler, also avoid the type of attachment of mistake.
Detailed description of the invention
The present invention will be further described for embodiment in detail below.
A kind of coronary vessel stent manufacture method, it is characterised in that comprise the following steps:
A. on the tubing of a diameter of 1mm, by the way of cut, form the multiple support rings cut out the most successively,
And offer groove in the middle part of each support ring；
B. the support ring obtained after a step is made annealing treatment, should with the remnants that removing produces when described cut
Power；
C. utilize Nitinol to be woven into tinsel, and tinsel outer surface plates titanium nitride material screen layer, then make net
Frame, and rack is placed in support ring；
D. support ring relevant position is carried out stretch bending, and welding forms wavy thin section successively, and process convex, then adopt
It is polished with electrochemical polishing machine, to not having two thin segments to carry out bonding after polishing.
The present invention has medicine-carrying trough, has and improves medicine distribution in the blood vessel, increases coating energy of attachment on support
Power, the advantage extending the action time of medicine.Carrier unit the most of the present invention, by bonding at trough, connects in " top is the end of to ",
Support list distance is diminished, so that the mesh area of support reduces, adds the support force to pathological changes speckle.
Again, it is provided with fool proof at the crest of thin segment side and connects convex, and connection breach is set at opposite side crest, make
Connect simpler, also avoid the type of attachment of mistake.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
