A lung volume reduction elastic implant (2) and a lung volume reduction device, wherein the lung volume reduction elastic implant (2) has a tubular shape, and includes an implant proximal end (201), an elastic deformation portion (205), and an implant distal end ( 202), the elastic deformation part (205) is located between the implant proximal end (201) and the implant distal end (202), and at least the elastic deformation part (205) has shape memory characteristics, and lung volume The reduced elastic implant (2) is opened at least at the proximal end (201) of the implant, and the elastic deformation (205) is provided with several kerfs (204) spaced along its length. Each kerf (204) communicates with the lumen of the elastic deformation part (205). The lung volume reduction device includes a lung volume reduction elastic implant (2) and a delivery device (1) as a set therewith, and the delivery device (1) includes a guide wire (101) and a hollow push-feed member (113). The lung volume reducing elastic implant (2) is detachably connected to the distal end of the hollow pusher member (113) by the implant proximal end (201), and the guide wire (101) is connected to the lung volume reducing elastic implant (2). The lumen and the lumen of the hollow push member (113) are movably penetrated. Lung volume reduction equipment further facilitates surgical operation, further reduces time, avoids damage to the bronchial lining, and reduces the incidence of pneumothorax.肺容積減少弾性インプラント(2)及び肺容積減少器械であって、肺容積減少弾性インプラント(2)は管状を呈し、インプラント近端(201)と、弾性変形部(205)と、インプラント遠端(202)を備え、弾性変形部(205)は、インプラント近端(201)とインプラント遠端(202)の間に位置し、かつ少なくとも弾性変形部(205)は形状記憶特性を有し、肺容積減少弾性インプラント(2)は、少なくともインプラント近端(201)に開口され、弾性変形部(205)には、その長さ方向に沿って間隔を隔てて幾つかの切溝(204)が設けられ、各切溝(204)は弾性変形部(205)の管腔と連通する。肺容積減少器械は、肺容積減少弾性インプラント(2)及びそれとセットとなるデリバリー装置(1)を備え、デリバリー装置(1)は、ガイドワイヤー(101)と、中空押し送り部材(113)を備え、肺容積減少弾性インプラント(2)は、インプラント近端(201)により中空押し送り部材(113)の遠端に着脱可能に連結され、ガイドワイヤー(101)は肺容積減少弾性インプラント(2)の管腔と中空押し送り部材(113)の管腔を移動可能に貫通する。肺容積減少器械は、手術操作をさら
