A lung volume-reducing elastic implant () and a lung volume-reducing instrument; the lung volume-reducing elastic implant () is tubular and comprises a proximal implant end (), an elastic deformation part () and a distal implant end (); the elastic deformation part () is located between the proximal implant end () and the distal implant end (), and the elastic deformation part () has a shape memory characteristic; the lung volume-reducing elastic implant () is opened at the proximal implant end (); the elastic deformation part () is provided with a plurality of grooves () at intervals along the longitudinal direction thereof; each groove () communicates with the tube cavity of the elastic deformation part (); the lung volume-reducing instrument comprises the lung volume-reducing elastic implant () and a delivery device () matching same; the delivery device () comprises a guidewire () and a hollow push piece (); the lung volume-reducing elastic implant () is detachably connected to the distal end of the hollow push piece () via the proximal implant end (); and the guidewire () passes through the tube cavity of the lung volume-reducing elastic implant () and the tube cavity of the hollow push piece (). The lung volume-reducing instrument is more convenient for an operation and takes shorter time, and avoids damage to the inner wall of the bronchia, reducing the occurrence of pneumothorax.
