Description

血管支架临时覆膜装置及血管支架临时覆膜的方法 Temporary intravascular stent coating apparatus and method for coating vascular stents temporary

技术领域 FIELD

[0001] 本发明涉及医疗器械,特别涉及血管支架临时覆膜装置和方法。 [0001] The present invention relates to medical devices, and more particularly to a vascular stent temporary coating apparatus and method.

背景技术 Background technique

[0002] 冠状动脉介入治疗中,由于支架尺寸、释放压力、后扩张压力或者预扩张压力过大,经常会出现冠状动脉穿孔的情况。 [0002] coronary intervention, since the size of the stent, the pressure was released, after pre-expanding or pressure expandable pressure, coronary arteries often occur perforation. 冠状动脉穿孔是冠状动脉介入治疗中常见的并发症, 而且情势凶险,如果处理不及时会导致急性心包填塞甚至死亡。 Coronary artery perforation is a common complication of interventional treatment, and the situation dangerous, if not promptly treated can lead to acute cardiac tamponade and death.

[0003] 当穿孔发生时,最迅速也最方便的方法是用和血管直径匹配的球囊用适当的压力扩张封堵破口,在破口不大时,有时该方法能奏效。 [0003] When a perforation occurs, the fastest and most convenient method is expanded and closure of the blood vessel diameter with the appropriate matching balloon pressure break when not break, which sometimes can work. 但大多数情况下都不能止住出血,如堵的时间太长又会发生心肌缺血甚至是急性血管闭塞造成急性心肌梗死。 But in most cases you can not stop the bleeding, such as blocking too long will happen even acute myocardial ischemia caused by vascular occlusion in acute myocardial infarction. 有时在穿孔处放一枚普通支架,也能止住出血,但效果不可靠。 Sometimes put at the perforation a common stand, can stop the bleeding, but the effect is not reliable.

[0004] 目前在所有处理这类冠状动脉穿孔的技术中,最常用也较有效的是冠状动脉带膜支架的使用。 [0004] Currently, all technical processing such coronary perforation, the most common and more efficient use of the coronary stent. 当穿孔发生时将备用的带膜支架输送到血管穿孔处以适当的压力释放以封闭破口。 When the perforation alternate stent delivery into a blood vessel perforation at the applicable pressure releasing closure to break. 但是带膜支架的使用存在欠缺之处:其一,带膜支架比较硬,而且外径也比较大,所以通过性能较差,在某些有扭曲、钙化或者相对细小的血管不易通过或不能使用;其二,带膜支架价钱较贵,每枚2万元人民币左右,而冠状动脉穿孔又不是常见的并发症,有时较长时间也不会碰上,过了效期带膜支架就不能用了,备货方就得自己承担这个损失。 However, using the present stent-graft gaps in: First, the stent is relatively hard, and the outer diameter is relatively large, Therefore, by performance is poor, there is some distortion, or calcification relatively easily through small blood vessels can not be used or ; Second, the stent price is more expensive, each costing about 20,000 yuan, while coronary perforation complications are not common, sometimes a long time and will not run, can not be used over a period of limitation stent , the stocking parties have to bear the loss themselves. 所以不是每个导管室都愿意备货。 So not every cath lab are willing stocking.

[0005] 考虑到上述欠缺,有些术者使用临时自制的带膜支架封堵破口,如从橡胶手套上剪下一小块碎片,缝扎在支架上,然后输送至血管穿孔处。 [0005] In view of the above lack of some patients to use temporary home-made stent occlusion break, such as a small piece of debris from the cut rubber gloves on the suture holder, then transported to the vessel perforation. 但是,临时自制带膜支架效果不是确切可靠,而且在穿孔发生时也没有足够的时间去制作带膜支架。 However, the temporary stent made exact effect is not reliable, but also in the perforation did not have enough time to make stent. 即使慌慌张张的制作好了,心包里也有了一定量的积血了,肯定会影响抢救效果。 Even a whirlwind production well, the heart bag also has a certain amount of hemorrhage, and certainly will affect the rescue effect.

[0006]基于目前冠状动脉穿孔的治疗局面及各种治疗技术不同程度的缺点,迫切需要一种装置,在穿孔发生时,能迅速、容易地被送到血管的穿孔处,及时有效地封堵破口。 [0006] Based on the current shortcomings of coronary perforation treatment situation and a variety of different levels of therapy, urgent need for a device, when the perforation, can quickly and easily be sent to vessel perforation, timely and effective closure break.

具体实施方式 Detailed ways

[0027]在以下的叙述中,为了使读者更好地理解本申请而提出了许多技术细节。 [0027] In the following description, in order to enable the reader to better understand the application and made many technical details. 但是,本领域的普通技术人员可以理解,即使没有这些技术细节和基于以下各实施方式的种种变化和修改,也可以实现本申请各权利要求所要求保护的技术方案。 However, those of ordinary skill in the art can be appreciated, without these technical details and various changes and modifications based on the following embodiments, the present application may also be implemented as claimed in claim various technical solution.

[0028]为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明的实施方式作进一步地详细描述。 [0028] To make the objectives, technical solutions, and advantages of the present invention will become apparent in conjunction with the following drawings, embodiments of the present invention will be described in further detail.

[0029]本发明第一实施方式涉及一种血管支架临时覆膜1装置,图1是该血管支架临时覆膜装置的结构示意图。 [0029] The first embodiment of the present invention relates to an intravascular stent temporary coating apparatus 1, FIG. 1 is a schematic view of the temporary blood vessel stent coating apparatus.

[0030]如图所示,该血管支架临时覆膜装置包括覆膜1和血管支架容纳中空套管2。 [0030] As shown, the apparatus comprises a film temporary blood vessel stent and a blood vessel stent coating 1 2 receiving a hollow sleeve.

[0031]覆膜1为管状弹性覆膜,套接在血管支架容纳中空套管2的外表面上,且覆膜丨在自由状态下的内径小于血管支架未释放时的外径,这样的设计保证了在所述支架容纳中空套管2抽出后,覆膜1能够紧密地包被支架; [0031] The elastomeric film is tubular film 1, a hollow sleeve receiving sockets on the outer surface 2 of the stent in the vessel, and an inner diameter in the free state Shu coating film is smaller than that when the blood vessel stent is not released, this design It ensures that after the holder accommodating hollow sleeve 2 out, the film 1 can be tightly coated stent;

[0032] 血管支架容纳中空套管2为管状且内径与未释放状态的血管支架的外径相匹配, 血管支架容纳中空套管2用于提供一个中空管腔,供血管支架在中空管腔中相对于血管支架容纳中空套管2平移,以间接地将血管支架引入覆膜丨所包围的管状空间内。 [0032] Vascular stents receiving a hollow sleeve 2 and the inner and outer diameters of the tubular stent to match the non-release state, the blood vessel stent for receiving a hollow sleeve 2 to provide a hollow lumen, a vascular stent for hollow lumen with respect to the hollow sleeve receiving vessel support pan 2, the inner space of the tubular vascular stent introduced indirectly surrounded Shu coating.

[0033] 一般而言,血管支架容纳中空套管2的内径与未释放状态的血管支架的外径相匹配是指血管支架容纳中空套管2的内径大于等于血管支架的外径。 [0033] In general, a vascular stent receiving the inner diameter of the hollow 2 and the outer diameter of the sleeve stent to match the non-release state refers to a vascular stent receiving hollow casing diameter equal to the outer diameter of greater than 2 stent.

[0034] 此外,可以理解,覆膜1必须有足够的弹性,因为血管支架到达体内靶位(即血管穿孔处)被释放后,覆膜1被血管支架撑开,如果覆膜i没有足够的弹性将会导致破损从而达不到封堵破口的效果。 [0034] Further, it is understood, a film must have sufficient flexibility as a vascular stent reach the target site in vivo (i.e., vascular perforation) after being released, the film 1 is stretched vascular stent, if there is not enough film i elasticity will lead to breakage and thus fail to block the effect of the breach.

[0035] 本实施方式的血管支架临时覆膜装置,能够利用分离的血管支架和覆膜1快速便利地制备带膜支架,在穿孔发生时及时有效地用临时制备的带膜支架封堵破口。 [0035] The vascular stent according to the present embodiment the temporary coating apparatus capable of using the isolated blood vessel stent and a coating prepared quickly and conveniently, stent-graft, perforation when a timely and effective stent occlusion break the extemporaneous preparation of . 且整个制备过程对覆膜1和血管支架基本没有硬接触,可保证覆膜丨的完整性并确保对血管支架的保护。 And throughout the preparation of the film and a blood vessel stent substantially no hard contact, ensure the integrity of the coating and to ensure the protection of Shu stent. 可避免传统昂贵带膜血管支架过期带来的成本问题。 It can be avoided with a conventional expensive costs brought expired film vascular stent. ^036]作为本实施方式的优选例,如图2所示为血管支架临时覆膜装置模型图。 ^ 036] As a preferred example of the present embodiment, as shown in FIG temporary intravascular stent coating apparatus model shown in Figure 2. 如图所示,无毒弹性硅胶覆膜为管状,预先装在血管支架容纳中空套管上,预先设计好管状硅胶覆膜的外径和长度,要求管状硅胶覆膜包被在支架上后,能牢牢抱紧支架,就像支架能牢牢抱紧支架球囊一样。 As shown, the coating film is non-toxic flexible silicone tube, previously mounted on a hollow sleeve receiving a vascular stent, the length of the pre-designed and the outer diameter of the tubular fine silica coating, requires the tubular film coated silica gel after the holder, to firmly hold the stent, as the stent can firmly hold the stent balloon same. 再将管状硅胶覆膜牢牢收紧在血管支架容纳中空套管上,使用时,取出该装置,选取和支架尺寸相匹配的管状硅胶覆膜,套在支架上,抽掉血管支架容纳中空套管, 这样管状硅胶覆膜就紧紧包被在支架上了,然后将包被有管状硅胶覆膜的支架输送至血管穿孔处用适当的压力(根据血管内径和支架尺寸的匹配情况以及支架出产设计的释放压和支架尺寸的关系)释放支架,随着弹性硅胶覆膜被支架撑开,血管破口也就被管状硅胶覆膜封住了。 The tubular film then firmly tightened on silica gel vessel holder accommodating a hollow sleeve, in use, the device is removed, the tubular silicone coating and the stent select match the size, set on the holder, removing the vascular stent receiving idler tube, so that the tubular pack is tightly silica coating on the carriage, and then the silica gel coated with a tubular coating at the stent delivery to the vessel with suitable perforations pressure (blood vessel diameter and the stent produced in accordance with the size and matching of the stent relationship between the release of pressure and size of the stent design) release the stent, the stent is covered with the stretched elastic silicone, the tubular vessel is silica coating will break the seal.

[0037]本发明第二实施方式涉及一种血管支架临时覆膜装置,图3是该血管支架临时覆膜装置的结构示意图。 Second Embodiment [0037] The present invention relates to an intravascular stent temporary coating apparatus, FIG. 3 is a schematic view of the temporary blood vessel stent coating apparatus.

[0038]第二实施方式在第一实施方式的基础上进行了改进,主要改进之处在于:覆膜端部设置有牵拉部,避免抽出血管支架容纳中空套管时覆膜跟着一起移动,从而便于顺利地将覆膜套接到血管支架上;覆膜和血管支架容纳中空套管具有与不同血管支架尺寸匹配的不同内径尺寸,通过选取与血管支架尺寸相匹配的覆膜和血管支架,可适用于不同尺寸冠状动脉的病人;覆膜为非排异性生化材料,可防止排异现象。 [0038] The second embodiment is an improvement on the first embodiment, mainly the improvement comprising: an end portion provided with a coating portion is pulled, pumped out to avoid a hollow sleeve receiving a vascular stent coating film move with it, thereby facilitating smoothly on the film set to a vascular stent; covered stents and vascular receiving a hollow sleeve having an inner diameter of different size and different sizes to match stent, a vascular stent by selecting the size that matches the vascular stent coating film and, is applicable to patients of different sizes coronary artery; non-exclusive anisotropic film biological material to prevent rejection phenomenon. 具体地说: Specifically:

[0043] 在另一优选例中,覆膜1和血管支架容纳中空套管2具有与不同血管支架尺寸匹配的不同内径尺寸,以形成对应不同尺寸血管支架的一个系列。 [0043] In another preferred embodiment, the film holder receiving vessel 1 and a hollow sleeve 2 having different sizes and different inner diameters match the dimensions of vascular stents, of different sizes to form the corresponding series of stents. 从而可根据血管直径自由选择血管支架。 The vascular stent may be selected so that the blood vessel diameter freedom. 而现有技术中的带膜支架的尺寸是定好的,不管血管直径如何,只能将就使用。 And the size of the stent-graft prior art is given good, regardless of the diameter of the vessel, will only use.

[0044]为方便叙述,现根据穿孔处冠状动脉直径的大小将冠状动脉穿孔分为血管直径> =2.25mm的冠脉穿孔和血管直径< = 2.25mm的冠脉穿孔两种。 [0044] For the convenience of description, on the basis of the size of the diameter of the coronary artery at the perforation perforated into the blood vessel diameter> = 2.25mm coronary perforation and two kinds of diameter of the perforations coronary vascular <= 2.25mm of. 血管直径< = 2.25mm的冠脉穿孔放不了支架,可以用明胶海绵直接堵闭血管即可,因血管小无甚大碍;本技术只负责解决血管直径> =2 • 25mm的冠脉穿孔问题,尤其是主支血管需要植入临时覆膜支架,临时覆膜内径可以做成2.25謂1、2.5咖、2_75謂1、3.〇111111、3.5111111、4.0咖,分别和相应尺寸的支架相匹配。 Vessel diameter <= 2.25mm not stented coronary perforation, can be blocked with gelatin sponge can be directly closed vessel, little affected by small blood vessels; this technique is only responsible for resolving vessel diameter> = 2 • 25mm coronary perforation problems, in particular, the main vessel stent graft requires temporary implants, the temporary inner diameter of the coating film can be made 2.25, 2.5 that coffee, coffee 1,3.〇111111,3.5111111,4.0 that 2_75, respectively and the stent correspondingly sized to match. [0045]在另一优选例中,覆膜为非排异性生化材料。 [0045] In another preferred embodiment, the non-exclusive anisotropic film biological material. 进一步地,覆膜的材料为无毒材料, 非排异性生化材料具体可以是无毒弹性娃胶。 Further, the coating material is non-toxic materials, particularly non-exclusive anisotropic material may be a non-toxic biochemical resilient plastic baby.

[0046]此外,覆膜也可以是生物可降解,生物可吸收的材料,能够在体内保持一段有效期。 [0046] In addition, the coating film may be biodegradable, bioabsorbable materials, can be maintained for a period in the body.

[0047]本发明第三实施方式涉及一种血管支架临时覆膜装置,第三实施方式在第一实施方式的基础上进行了改进,主要改进之处在于:血管支架容纳中空套管的外表面是光滑的, 抽取血管支架容纳中空套管时不会对覆膜造成磨损;血管支架容纳中心套管的内表面是光滑的,将血管支架插入血管支架容纳中空套管时比较容易,且不会对血管支架造成损伤。 [0047] The third embodiment of the present invention relates to an intravascular stent temporary coating apparatus, the third embodiment is improved based on the first embodiment, mainly the improvement comprising: receiving a vascular stent outer surface of the hollow sleeve smooth, extraction vessel stent coating will not cause wear on when receiving a hollow sleeve; an inner surface of the stent to accommodate the central spigot is smooth, relatively easily when receiving a vascular stent into a blood vessel stent of the hollow sleeve, and does not damage to the stent. 具体地说: Specifically:
