Abstract
An implant (500) comprises an elastic deformation portion (51) and a connection portion (52) connected with the proximal end (511) of the elastic deformation portion (51), wherein the elastic deformation portion (51) is covered by an elastic outer layer (55); the proximal end of the connection portion (52) is surrounded by a tightening ring (58); and the proximal end of the elastic outer layer (55) is covered by the tightening ring (58). Since the proximal end of the elastic outer layer (55) of the implant (500) is surrounded by a tightening ring (58), the elastic outer layer (55) is closely attached on the connecting portion (52) of the implant (500), such that the elastic outer layer (55) can be prevented from being rolled over from the surface of the implant (500) when the implant (500) is implanted, thereby improving safety of lung volume reduction surgery.
