Abstract
(EN) A developing structure, a stent, and a thrombectomy system. The developing structure of the present invention comprises at least one protrusion portion for fixing, supporting, and connecting a developing sleeve (2); at least one developing sleeve (2), said at least one developing sleeve (2) sleeving the at least one protrusion portion; at least one filler portion (3), said at least one filler portion filling the gap between the developing sleeve (2) and the protrusion portion. Compared to the prior art, the present invention enhances the visualization of the remote aspiration point of a laser cutting thrombectomy apparatus, solving the visualization problem of inability to display all metal rods of a laser thrombectomy apparatus under visual conditions. The developing structure of the present invention can be used for all stents, and is not limited to thrombectomy apparatuses.
(FR) Structure de développement, endoprothèse et système de thrombectomie. La structure de développement selon la présente invention comprend au moins une partie en saillie servant à fixer, supporter et raccorder un manchon de développement (2); au moins un manchon de développement (2), ledit au moins un manchon de développement (2) entourant ladite partie en saillie; au moins une partie de remplissage (3), ladite au moins une partie de remplissage remplissant l'espace séparant le manchon de développement (2) et la partie en saillie. Par rapport à l'état de la technique, la présente invention améliore la visualisation du point d'aspiration à distance d'un appareil de thrombectomie par coupe au laser, résolvant le problème de visualisation d'incapacité à afficher toutes les tiges métalliques d'un appareil de thrombectomie au laser dans des conditions visuelles. La structure de développement selon la présente invention peut être utilisée pour toutes les endoprothèses, et n'est pas limitée aux appareils de thrombectomie.
(ZH) 一种显影结构、支架及取栓系统，显影结构包括至少一突出部，以用于固定、支撑和连接显影套（2）；至少一显影套（2），显影套（2）套设在至少一突出部上；至少一填充部（3），至少一填充部填充于显影套（2）与突出部之间的空隙。与现有技术相比，显影机构可以增强激光切割取栓装置远端显影点的可视性能，解决在可视条件下无法展示激光取栓装置所有金属杆的可视问题，显影结构可用于所有支架，不限于取栓装置。
