A lung volume reduction elastic implant (500) and a lung volume reduction instrument are provided. The lung volume reduction elastic implant (500) has 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) has 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 radiograph 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.
