Abstract
The utility model discloses a new aortic bracket blood vessel and primarily comprises a bracket and an artificial blood vessel covered on the surface of the bracket; bracket units are connected to form the bracket, and the blood vessel covered on the first and the second bracket is provided with a V-shaped gap; the V-shaped gap is corresponding to the opening of the aortic arch left subclavian artery when released to the body, and the blood flow of the left subclavian artery is guaranteed when occluding the aortic aneurysm or dissection. The utility model avoids the possibility of cerebral steal phenomenon and ischemia of the left upper limb after operation efficiently.
Description
Technical field
This utility model relates to a kind of medical aortic stents blood vessel, belongs to the element in the implant into body.
Background technology
Along with the hypertensive sickness rate of China is high, population steps into the aging stage, and hyperlipidemia and incidence of atherosclerosis rate rise year by year, and aneurysm of thoracic aorta and Human Thoracic Aortic Dissection disease incidence rate are also obviously in rising trend.Aneurysm of thoracic aorta and Human Thoracic Aortic Dissection are the diseases of serious threat patient life security, if untimely the treatment, the tumor body of aneurysm of thoracic aorta increases, and finally cause breaking, in case break, mortality rate can surpass 90%; And the harm of Human Thoracic Aortic Dissection is to cause at short notice that brain, internal organs and limb ischemia or thoracic aorta break, and causes death.
Hinder the development of interventional therapeutic technique along with Wicresoft, EVAR treatment arotic disease is used widely, several generation development and perfect have also been passed through around the support blood vessel on the domestic and international market, various forms of support blood vessels have appearred, support blood vessel in the market mainly around the radial support power of improving support, prevent internal hemorrhage due to trauma, strengthen development effect, reduce metal coverage rate and displacement phenomenon and improve.Aortic arch sends innominate artery, left common carotid artery, left subclavian artery, in order to increase the mount proximal end anchorage zone, behind the support blood vessel implant into body in the market, need shutoff left subclavian artery to some extent, may cause brain to steal blood or left upper extremity ischemia.
Summary of the invention
The purpose of this utility model is to improve the structure of existing support, and a kind of breach type aortic stents blood vessel is provided.This supporting structure can guarantee sufficiently long proximal landing zone, can avoid sealing left subclavian artery again, has eliminated the probability that the postoperative brain is stolen blood and left upper extremity ischemia.
The designed aortic stents blood vessel agent structure of this utility model is made up of support and the artificial blood vessel that overlays on the surface, support is centered on by plural carrier unit and connects to form, the first segment of support and the second joint carrier unit are " V " font, each carrier unit of support all links to each other by artificial blood vessel, and the support appearance is all covered by artificial blood vessel, its upper end artificial blood vessel has at least one " V " font breach, and the shape of integral support is straight cylinder or gradually thin cylindrical structure.
Above-mentioned aortic stents blood vessel, the carrier unit except that the first segment and second joint is " Z " font or waveform.
Aortic stents blood vessel medium-height trestle is made by memory alloy material.
Advantage of the present utility model is:
1. easy to use.After utilizing induction system to be transported to support in patient's body, support can automatically restore to original shape under human body temperature, be supported on patient's aortic arch place, keeps the enough tension force of blood vessel wall, and it is simple to operate, has effectively shortened operating time.
2. guarantee the left subclavian artery blood flow.The artificial blood vessel of the support first segment and second joint has " V " font breach, and the opening of " V " font notch alignment left subclavian artery when making effective shutoff aortic aneurysm of support blood vessel and interlayer, guarantees the blood flow of left subclavian artery.
3. pliability is good.The carrier unit that respectively saves of support blood vessel all is formed by connecting by artificial blood vessel, and this connected mode had both made the support blood vessel have good flexible, more can adapt to the curved course of aortic arch, greatly reduce the metal coverage rate again.
4. meet physiological characteristics.Entire bracket is straight cylinder or gradually thin cylindrical structure, can select the support blood vessel according to patient's different situations, more meets the shape or the trend of human aortic.
Description of drawings
Fig. 1 is the designed aortic stents blood vessel structure sketch map of this utility model;
Fig. 2 is the sketch map of aortic stents blood vessel user mode.
The specific embodiment
As shown in Figure 1, aortic stents blood vessel of the present utility model is by memorial alloy tubular bracket 1 and overlay on its surperficial artificial blood vessel 2 and form.Support 1 is formed by connecting by artificial blood vessel 2 by more piece metal rack unit, and carrier unit is formed by the heat treatment typing by memory alloy wire, and overall structure is gradually thin cylindrical structure, and is similar to the shape of aorta vessel.
The artificial blood vessel bracket unit of the first segment and the second joint carrier unit is " V " font, has " V " font breach 3 on it, and the remaining stents unit is " Z " font.In use, as shown in Figure 2, behind the aortic stents blood vessel implant into body, " V " font breach 3 makes support not influence the blood flow of left subclavian artery in shutoff aortic aneurysms or dissections 5 facing to the opening part of left subclavian artery 4.
The aortic stents blood vessel respectively saves carrier unit and connects into an overall structure by artificial blood vessel, makes support have good flexible, does not influence the mechanical performance of material simultaneously.Overall structure is straight cylinder or gradually thin cylindrical structure, more meets the characteristic of human aortic.
Because the character of used memory alloy material is for the aortic stents blood vessel is softer at low temperatures, yielding, therefore can take in comparalive ease in the conveyer device, the support blood vessel be sent into the aortic disease place, discharge support by conveyer device, under human body temperature, according to the shape memory effect of material, support can resile automatically, and the support blood vessel is tightly sticked on the aortic blood tube wall, play the effect that intracavity is repaired, reach the purpose of treatment.
Claims (3)
1. aortic stents blood vessel, agent structure is made up of support and the artificial blood vessel that overlays on the surface, support be is characterized in that around connecting to form by plural carrier unit: the carrier unit of the first segment of support and second joint is " V " font, each carrier unit of support all links to each other by artificial blood vessel, and the support appearance is all covered by artificial blood vessel, have at least one " V " font breach on its end first segment and the second joint artificial blood vessel that support coated, the shape of integral support is straight cylinder or gradually thin cylindrical structure.
2. aortic stents blood vessel according to claim 1 is characterized in that: the remaining stents unit in the support except that the first segment and second joint is " Z " font or waveform.
3. aortic stents blood vessel according to claim 1, it is characterized in that: support is made by memory alloy material.
