一种介入瓣膜释放限位装置An interventional valve release limiting device

技术领域technical field

本发明涉及医疗器械技术领域，特别涉及到一种介入瓣膜释放限位装置。The invention relates to the technical field of medical devices, in particular to a release limiting device for an interventional valve.

背景技术Background technique

在经导管的瓣膜置换术中，当术者将带有瓣膜的导管放置在合适位置时，需要对瓣膜内的气囊充气来保证瓣膜的顺利展开，然而目前市面上的气囊整体呈橄榄球形，即横截面为椭圆形(如图1所示)，采用此种结构的气囊10在充气撑开瓣膜20时，会使瓣膜在气囊外侧发生或多或少的位移，即定位不准确，这将导致瓣膜释放位置发生偏移，严重影响了手术质量，给术者的瓣膜置换工作带来了较大的不便。In transcatheter valve replacement, when the operator places the catheter with the valve in the proper position, the balloon in the valve needs to be inflated to ensure the smooth deployment of the valve. The cross section is oval (as shown in Fig. 1), when theballoon 10 with this structure is inflated to spread thevalve 20, the valve will be displaced more or less outside the balloon, that is, the positioning will be inaccurate, which will lead to The deviation of the valve release position seriously affects the quality of the operation and brings great inconvenience to the operator's valve replacement work.

具体实施方式Detailed ways

为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体图示，进一步阐述本发明。In order to make the technical means, creation features, achievement goals and effects of the present invention easy to understand and understand, the present invention will be further described below with reference to the specific drawings.

参照图1-图3所示，图中给出了一种介入瓣膜释放限位装置，包括膨胀气囊100、第一充气系统和一对称设置在膨胀气囊100两端且用于限制瓣膜300张开的位置的限位气囊200。Referring to FIGS. 1-3 , an interventional valve release limiting device is shown in the figures, including aninflation balloon 100, a first inflation system, and a symmetrical arrangement at both ends of theinflation balloon 100 for limiting the opening of thevalve 300 The position of thelimiting airbag 200.

膨胀气囊100用于扩张瓣膜300，在膨胀气囊100上开设有第一充气口110，第一充气系统用于为膨胀气囊100进行充放气，第一充气系统通过第一管路400与膨胀气囊100的第一充气口110相连通。Theinflation balloon 100 is used for expanding thevalve 300 , afirst inflation port 110 is opened on theinflation balloon 100 , the first inflation system is used to inflate and deflate theinflation balloon 100 , and the first inflation system communicates with the inflation balloon through thefirst pipeline 400 . Thefirst inflation ports 110 of 100 are communicated with each other.

上述膨胀气囊100可以在术中反复充气与放气，与瓣膜300只是表面相互接触，并不存在连接固定，当瓣膜300扩张处于合适位置时，可通过导管将气囊脱离瓣膜。The above-mentionedinflation balloon 100 can be repeatedly inflated and deflated during the operation, and thevalve 300 is only in contact with each other on the surface, and there is no connection and fixation.

在限位气囊200上开设有第二充气口210，限位气囊200的第二充气口210通过第二管路500与用于为其进行充放气的第二充气系统相连通，第一充气系统与第二充气系统为两个独立的充气系统，且分别对膨胀气囊100与限位气囊200进行充气，相互独立控制，互不干扰。Asecond inflation port 210 is opened on thelimiting airbag 200 , and thesecond inflation port 210 of the limitingairbag 200 is communicated with a second inflation system for inflating and deflating thelimiting airbag 200 through asecond pipeline 500 . The system and the second inflation system are two independent inflation systems, and respectively inflate theinflation airbag 100 and the limitingairbag 200, and are controlled independently of each other without interfering with each other.

限位气囊200与膨胀气囊100采用一体成型结构一体成型，采用此种结构有效的提高了限位气囊200与膨胀气囊100之间的稳定性能，避免限位气囊200相对膨胀气囊100发生移动。Thelimiting airbag 200 and the inflatingairbag 100 are integrally formed by an integral molding structure. This structure effectively improves the stability between the limitingairbag 200 and theinflation airbag 100 and prevents the limitingairbag 200 from moving relative to theinflation airbag 100 .

膨胀气囊100膨胀的最大外径与瓣膜300张开的最大内径相同，不同的瓣膜尺寸会有相应的膨胀气囊，保证其处于最佳合适状态，上述所有的材料完全能够适应医学器械的消毒要求。The maximum outer diameter of theinflation balloon 100 is the same as the maximum inner diameter of thevalve 300. Different valve sizes will have corresponding inflation balloons to ensure that they are in the best and appropriate state. All the above materials can fully meet the disinfection requirements of medical instruments.

本发明的具体操作如下：The concrete operation of the present invention is as follows:

当术者将瓣膜300输送到所需要的位置时，此时通过第二充气系统对限位气囊200进行充气，保证瓣膜300不会移位，接着再通过第二充气系统对膨胀气囊100进行充气，使瓣膜300充分展开，术者可根据术中心超或X线引导下，反复充放气，保证瓣膜300处于合适的位置展开，最后再通过第一充气系统、第二充气系统将膨胀气囊100和限位气囊200中的气抽走，通过导管将气囊取走。When the operator delivers thevalve 300 to the desired position, thelimiting airbag 200 is inflated by the second inflation system to ensure that thevalve 300 will not be displaced, and then theinflation airbag 100 is inflated by the second inflation system so that thevalve 300 can be fully deployed, and the operator can repeatedly inflate and deflate according to the guidance of the operation center ultrasonography or X-ray to ensure that thevalve 300 is deployed in a suitable position. And the air in thelimiting air bag 200 is withdrawn, and the air bag is removed through the catheter.

综上所述本发明在膨胀气囊的两端分别设有一限位气囊，有效地保证了介入瓣膜在释放过程中不会因为膨胀气囊的膨胀而导致瓣膜的移位，保证了介入瓣膜释放位置的准确性，极大地提高了瓣膜释放的成功率和手术质量，给术者的瓣膜置换工作带来了较大的便利。In summary, the present invention is provided with a limit airbag at both ends of the inflation airbag, which effectively ensures that the intervention valve will not be displaced due to the expansion of the inflation airbag during the release process, and ensures the release position of the interventional valve. The accuracy greatly improves the success rate of valve release and the operation quality, and brings great convenience to the operator's valve replacement work.
