Abstract
(EN)
A lung volume reduction elastic implant (500) and a lung volume reduction instrument. The lung volume reduction elastic implant (500) comprises: an elastic deformation part (51), and a flexible guide (53, 53a) connected to the distal end of the elastic deformation part (51). The flexible guide (53, 53a) is provided with a first flexible part (531). The first flexible part (531) comprises an insert part (5312) and a distal part (5311). The insert part (5312) is connected to the distal end of the elastic deformation part (51). The distal end of the distal part (5311) of the first flexible part (531) is the distal end of the lung volume reduction elastic implant (500). The first flexible part (531) is internally provided with a development component (56). The lung volume reduction elastic implant (500) and the lung volume reduction instrument use the implant (500) to provide a sufficient bending force while maintaining better flexibility, reducing the risk of bronchus contusion when the implant (500) is bent after the implant (500) is implanted into a bronchial tube and enhancing the safety of lung volume reduction surgery.

La présente invention concerne un implant élastique de réduction du volume pulmonaire (500) et un instrument de réduction du volume pulmonaire. L'implant élastique de réduction du volume pulmonaire (500) comprend : une partie de déformation élastique (51), et un guide flexible (53, 53a) raccordé à l'extrémité distale de la partie de déformation élastique (51). Le guide flexible (53, 53a) est pourvu d'une première partie flexible (531). La première partie flexible (531) comprend une partie d'insert (5312) et une partie distale (5311). La partie d'insert (5312) est raccordée à l'extrémité distale de la partie de déformation élastique (51). L'extrémité distale de la partie distale (5311) de la première partie flexible (531) est l'extrémité distale de l'implant élastique de réduction du volume pulmonaire (500). La première partie flexible (531) est pourvue intérieurement d'un composant de développement (56). L'implant élastique de réduction du volume pulmonaire (500) et l'instrument de réduction du volume pulmonaire utilisent l'implant (500) pour fournir une force de flexion suffisante tout en conservant une meilleure flexibilité, réduisant le risque de contusion de bronches lorsque l'implant (500) est plié après que l'implant (500) est implanté dans un tube bronchique et améliore la sécurité de la chirurgie de réduction du volume pulmonaire.
