Description

介入医疗器械推送装置 技术领域
本申请涉及医疗器械技术领域，尤其涉及一种用于输送介入医疗器械的介入医疗器械推送装置。
背景技术
腔内介入治疗技术的发展，基本涵盖了心血管主要病种，为心血管病的治疗带来了革命性的变化。当今，冠心病、结构性心脏病及大血管病等，介入治疗已成为首先考虑的方案，已成为继内科、外科之后第三大治疗学科，相较于外科手术，介入治疗创伤小、技术易于推广，可以惠及更多的病患，为患者带来福音。
腔内介入医疗器械(如左心耳封堵器、血管塞、滤器等)的输送系统通常包括输送鞘管装置、扩张装置、装载装置、推送装置等几个部分。输送鞘管装置和扩张装置先建立好通道，然后撤出扩张装置，通过推送装置将介入医疗器械收入装载装置，接着连接输送鞘管装置与装载装置，通过推送装置将介入医疗器械导入输送鞘管内，直至将介入医疗器械输送至靶向位置。推送装置必须具有对介入医疗器械的固定、输送、分离或回收等功能，现有的输送装置一般包括旋转装置、平移装置、锁定装置等多个相互独立工作的装置。因此，使用现有的输送装置时，需要分别操作旋转装置、平移装置及锁定装置，操作复杂，使用不方便，降低了推送装置的可靠性，出现操作问题的概率较大，从而影响手术的成功率。
申请内容

第一控制组件包括驱动推送件转动的第一转动机构；
第二控制组件包括驱动推送管在推送件外转动的第二转动机构。
本申请提供的介入医疗器械推送装置包括壳体、推送组件、第一控制组件和第二控制组件，第一控制组件包括驱动推送件转动的第一转动机构，第二控制组件包括驱动推送管在推送件外转动的第二转动机构，推送件的远端设置用于与介入医疗器械连接和分离的第一连接部，推送管的远端设置用于与介入医疗器械连接和分离的第二连接部。本申请的介入医疗器械推送装置通过第一转动机构驱动推送件转动实现介入医疗器械与第一连接部连接和分离，第二转动机构驱动推送管在推送件外转动实现介入医疗器械与第二连接部连接和分离，因此，本申请的介入医疗器械推送装置因具有第一转动机构和第二转动机构能够提高对介入医疗器械连接、输送和分离的可靠性和稳定性。
