Abstract
The utility model relates to a dilating support inside blood vessels. The support is of a spiral type structure. Fluctuation bent positions 4 are arranged in each circle of spiral. Both ends of the support are respectively provided with a spherical body 1. The support can be use for the intervention therapy of the angiostenosis of coronary artery blood vessels. The utility model has favorable curative effect.
Description
This utility model relates to a kind of intravascular dilation support that is used for the treatment of coronary stricture or other position angiostenosis.
The intravascular dilation support began in clinical use in 1986 as a kind of mechanicalness interventional therapy means, was to handle the most effective means of acute vascular obturation.It is metal rack forever to be put stay in the coronary artery pathological changes place, supports blood vessel wall through the balloon expandable mode, to keep the opening of coronary artery tube chamber, reduces the outbreak and the mortality rate of acute myocardial infarction.Simultaneously, after support is placed, owing to obtained enough big tube chamber, reduced that postoperative residue is narrow, elastical retraction and blood vessel plasticity again, thereby made restenosis rate be reduced to 10-20%.The support of using clinically is coiled type support and tubular bracket at present.The coiled type support is better at IC vascular compliance, can arrive focus by crooked blood vessel, influences seldom that side is propped up and branch's blood flow, but support force is lower, and effect is not really desirable.The support force of tubular bracket is higher than the coiled type support, but pliability is lower than the coiled type support in blood vessel, and is also bigger to the damage of blood vessel.
The purpose of this utility model is exactly to solve the deficiency described in the background technology, and provide that a kind of support force is moderate, pliability good, the expandable stent of injured blood vessel not.
The technical solution that realizes above-mentioned purpose is:
This intravascular dilation support mainly is that this support is a sped structure, all has the fluctuating knee in each circle spiral, and the two ends of support respectively are provided with a spheroid.At least have two fluctuating knee in each circle spiral.
Fig. 1: structural representation of the present utility model.
Fig. 2: support casing is contained in the structural representation on the sacculus.
Below with reference to drawings and Examples this utility model is done an explanation.
As shown in Figure 1, this support is a sped structure, is equipped with 2-8 fluctuating knee 4 in each circle spiral, and two terminations of support become two spheroids 1 through laser treatment.The platinum alloy silk that said support adopts 0.1-0.25mm is coiling on the plug of 0.8-1.8mm at diameter directly, and then moves to and carry out high annealing and typing on the stationary core rod and handle and form.Earlier the coronary artery pathological changes place is carried out predilation during clinical use, again with sacculus 3 taking-ups, then this support casing on sacculus 3 (referring to Fig. 2) with sacculus 3.Send into lesion.After sacculus 3 expansion this support strutted and be supported in blood vessel, take out sacculus 3 again, support then can permanently be put and stay in the coronary artery pathological changes place, thereby reaches the purpose of treatment coronary stricture.
The utlity model has following advantage:
1, expansionary force is little, opens easily at affected area, makes things convenient for operation technique.
2, axially pliability is good, can waltz through crooked coronary artery, arrives exactly lesions position, Difficult drop-off in the operation technique, the success rate of operation height.
3, stent support power and LVFS are moderate, and overall dimensions are less.
4, the direction of scaffolding thread has reduced the blood flow eddy current along blood flow direction.Also because this structural reason, can injured blood vessel, be difficult for motion after inserting blood vessel, thereby reduced thrombosed probability.
5, this support can be applicable to the blood vessel of different-diameter and be fit to different patients, thus can reduce the stock of hospital, thus reduce hospital expenses.
6, cost own is lower, can reduce surgery cost greatly, alleviates patient's burden.
7, can be made into elongate structure, make the long patient of some diseased regions when interventional therapy, only use a support just can reach therapeutic purposes, also can reduce surgery cost.
8, this support can be sold separately, also can with the sacculus systems selling, to make things convenient for the use of hospital.
Claims (2)
1, a kind of intravascular dilation support is characterized in that this support is a sped structure, all has fluctuating knee (4) in each circle spiral, and the two ends of support respectively are provided with a spheroid (1).
2, support as claimed in claim 1 is characterized in that having two fluctuating knee (4) at least in each circle spiral.
