Description

Y型大动脉覆膜支架 Y-aortic stent graft

技术领域 FIELD

本实用新型涉及一种为治疗腹主动脉瘤的微创伤介入医疗器械产品,具体地说涉及一种大动脉覆膜支架。 The present invention relates to a method for the minimally invasive treatment of abdominal aortic aneurysms interventional medical devices, and more particularly, to a main artery stent graft.

背景技术 Background technique

动脉瘤是临床上十分凶险的一种血管疾病,多发生在55岁左右的老年人,但近年来开始逐渐向中、青年人群发展。 An aneurysm is a very dangerous clinical vascular disease, occurs in the elderly about 55 years, but in recent years began to develop in young people gradually. 据相关统计资料表明:动脉瘤患者如果不及时采取的治疗措施,在24小时内的死亡率达15%左右,一周以内的死亡率达30%左右,一个月内的死亡率达75%左右,而5年的生存率仅为17%。 According to relevant statistics show that: treatment aneurysms if not promptly taken, the mortality rate within 24 hours of up to 15% mortality within a week of up to 30% mortality rate within a month up to about 75%, the 5-year survival rate of only 17%. 因此,一经发现动脉瘤患者,应尽快对其进行相应治疗。 Therefore, once discovered aneurysm patients should be treated accordingly as soon as possible.

目前,利用腔内隔绝原理的微创伤介入治疗技术得到广泛的利用,它是用一套管径较细的输送系统,将被压缩状态的大动脉覆膜支架送达病变血管的位置,在准确定位后,将其释放并覆盖病变血管,隔绝瘤腔并形成新的血流通道;动脉瘤在丧失血液供应后,瘤腔内残留血液逐渐形成血栓并肌化成血管组织,扩张状态的瘤壁因受负压而收缩,逐渐恢复到接近原始形态,从而达到治疗动脉瘤的目的。 Currently, the use of minimally invasive endovascular exclusion principle interventional therapy is widely utilized, which is a smaller diameter delivery system, the compressed state of the stent graft aortic vascular lesions delivery position, at the exact after positioning the cover release and vascular lesions, and isolated tumor cavity to form a new blood flow passageway; aneurysm after loss of blood supply, intraluminal thrombus and residual blood gradually muscle tissue into the blood vessel, the expanded state of the aneurysm wall by contracted by the negative pressure is gradually restored to near original form, so as to achieve the purpose of treating an aneurysm.

当动脉瘤位于腹主动脉与髂动脉的交汇处附近时,应使用外形与血管形状相似的Y型大动脉覆膜支架,其中:Y型大动脉覆膜支架的主体部分位于腹主动脉内,二个分支分别位于髂动脉内,分别完成对瘤腔的有效隔绝,从而达到对腹主动脉瘤的治疗。 When the aneurysm is located near the junction of the abdominal aorta and iliac arteries, use similar shape vascular stent graft aortic Y-shape, wherein: the body portion of the Y-shaped aortic stent graft positioned within the abdominal aorta, two internal iliac artery branches are located, respectively, on the tumor cavity effectively isolated from the completion to achieve the treatment of abdominal aortic aneurysms.

由于患者的病变血管形态因人而异,很大一部分患者的髂动脉部分存在较为较严重的弯曲,目前市场上已经存在的大多数Y型大动脉覆膜支架难以适用在类似的病变血管中。 Because the tumor vascular morphology of patients vary, iliac artery part of a large proportion of patients there is a more serious bent, currently on the market already exists for most Y-type main artery stent graft difficult to apply in a similar lesions in blood vessels. 现有大动脉覆膜支架在这种环境下的主要缺点主要表现在:大动脉覆膜支架释放后,支架近端内漏;位于髂动脉内的大动脉覆膜支架分支易打折,导致内径狭窄、内漏、支撑力减弱、输送系统难以撤出、甚至发生支架滑脱或移位等。 Conventional aortic stent graft main drawback in this context the main problems: the release of the aortic stent graft, stent proximal endoleak; aortic stent graft positioned within the iliac artery branches discount easily, leading to a narrow inner diameter, endoleaks supporting force is weakened, it is difficult to withdraw the delivery system, or even slipping or displacement of the stent and the like.

发明内容 SUMMARY

本实用新型需要解决的技术问题是设计一种Y型大动脉覆膜支架,以克服现有技术存在的大动脉覆膜支架释放后,支架近端内漏;位于髂动脉内的大动脉覆膜支架分支易打折,导致内径狭窄、内漏、支撑力减弱、输送系统难以撤出、发生支架滑脱或移位等缺陷,为一种一体式的、近端防内漏设计、分支弯曲顺应性更好、适应症范围更大的用于腹主动脉瘤微创伤介入治疗的Y型大动脉覆膜支架。 The present invention The technical problem to be solved is to design a Y-shaped aortic stent graft, in order to overcome the aortic stent graft is released, the proximal end of the stent leakage in the prior art; aortic stent graft positioned within the iliac artery branches Yi discounts, leading to a narrow inner diameter, internal leakage, a support force is weakened, it is difficult to withdraw the delivery system, the stent slipping or displacement defects and the like, within a one-piece, the proximal end of the leakproof design, better compliance bent branch, adapted disease greater scope for minimally invasive abdominal aortic aneurysm stent graft aorta Y-intervention therapy.

本实用新型的技术方案:一种Y型支架,由一个主体部分和二个分支部分构成,主体部分和分支部分包括多个合金丝制成的含有多个波形的柱状单圈构成的支架和Y形的管状覆膜,支架与覆膜由医用的外科手术缝合线缝合在一起,成为一个完整的Y型覆膜支架。 The present invention technical solutions: A Y-shaped bracket composed of a body portion and two branch portions, and a body portion and a branch portion Y includes a cylindrical holder containing a plurality of single-turn made of a plurality of waveforms composed of alloy wire the tubular-shaped film, and the film holder by a surgical stapling medical sutures together, as a complete Y-shaped stent graft.

所说的柱状单圈包括第一类柱状单圈,第二类柱状单圈和第三类柱状单圈;所说的第一类柱状单圈和第二类柱状单圈展开后,波形的所有波峰均在同一直线上,所有波谷也均在同一直线上,且第一类柱状单圈和第二类柱状单圈的区别在于:第二类柱状单圈的波形更小、波数更多;所说的第三类柱状单圈展开后,所有波谷均在同一直线上,所有波峰从中间的波峰向外,依次逐渐升高;所说的第一类柱状单圈和第二类柱状单圈的两端各自用连接件连接后,分别形成一个圆柱;所说的第三类柱状单圈的两端用连接件连接后,形成一个斜圆柱;所有柱状单圈与管状的覆膜通过缝合线缝合成一个整体,即构成Y型大动脉覆膜支架;所说的Y型支架的主体部分使用的柱状单圈及次序为:第一个为第一类柱状单圈,第二个为第二类柱状单圈,其余为第一类柱状单圈 Said ring comprises a first cylindrical single-type pillar lap, a second lap and a third type cylindrical columnar lap type; rear pillar of said first type and second type pillar lap lap deployed, all the waveform peaks are in the same line, all troughs are also in the same line, and the difference between the first type and second type cylindrical columnar lap lap in that: a second waveform type pillar lap smaller, more wave number; the after said third type of lenticular lap expanded and all troughs are on the same straight line, all the peaks from the intermediate peak outwardly gradually increased sequentially; pillar of said first type and second type pillar lap lap after both ends of each connecting member is connected, respectively, to form a cylinder; the two ends of said third type columnar connection with the lap element is connected to form a helical cylindrical; all columnar lap seam of the tubular film through the suture synthesis of a whole, constitute a Y-shaped aortic stent graft; lap columnar body portion of said sequence and Y-stent was used: first a first cylindrical lap type, a second type of the second cylindrical lap, the remainder being a first type pillar lap 所说的Y型支架的分支部分使用的柱状单圈均为第三类柱状单圈;本实用新型的优点是十分明显的:位于覆膜近端的第二类柱状单圈除提供足够的支撑力外,由于波形小,波间间隔少,能够适应非规则截面形状的血管,并有效的增加大动脉覆膜支架近端的贴壁效果,因此可以显著的减少近端内漏的可能性;大动脉覆膜支架分支上的所有第三类柱状单圈形成的斜圆柱的斜面朝向都朝向外侧,则分支的相邻圆柱之间在外侧的间隙更大,即使分支发生较大的弯曲,也不会出现相邻圆柱间的重叠,避免使支架弯折,从而保证覆膜内壁光滑、柔顺、贴壁效果更好,极大地提高了大动脉覆膜支架分支的弯曲顺应性能,使支架也适合于治疗弯曲严重的血管病变,扩大了大动脉覆膜支架的适应症范围,减小了手术难度和风险,提高了手术的成功率和术后患者的存活 He said Y branch portion of the stent used in the third type are lap cylindrical columnar lap; advantage of the present invention is very clear: the proximal end of a second type located columnar film lap In addition to providing sufficient support external force, due to the small wave, wave interval between the less, it is possible to adapt to the irregular shape of the vessel cross-section, and effectively increase the effect of the adherent aortic stent graft proximal end, and therefore can significantly reduce the possibility of leakage of the proximal end; aorta all inclined surface inclined cylindrical columnar third category lap formed on the stent graft branches are toward the outward, the greater the gap between the adjacent outer side of the cylindrical branch, branch even greater bending occurs, it will not overlap occurs between adjacent cylinder, to avoid the stent is bent, thereby ensuring smooth wall coating, supple, better adherent, compliant greatly improved bending performance aortic stent graft branches, is also suitable for the treatment of the stent is bent severe vascular disease, expanding the range of indications aorta stent graft, reducing the surgical difficulty and risk, improve the success rate of surgery and postoperative survival .
