Abstract
A lung volume-reducing elastic implant (2) and a lung volume-reducing instrument; the lung volume-reducing elastic implant (2) is tubular and comprises a proximal implant end (201), an elastic deformation part (205) and a distal implant end (202); the elastic deformation part (205) is located between the proximal implant end (201) and the distal implant end (202), and the elastic deformation part (205) has a shape memory characteristic; the lung volume-reducing elastic implant (2) is opened at the proximal implant end (201); the elastic deformation part (205) is provided with a plurality of grooves (204) at intervals along the longitudinal direction thereof; each groove (204) communicates with the tube cavity of the elastic deformation part (205); the lung volume-reducing instrument comprises the lung volume-reducing elastic implant (2) and a delivery device (1) matching same; the delivery device (1) comprises a guidewire (101) and a hollow push piece (110); the lung volume-reducing elastic implant (2) is detachably connected to the distal end of the hollow push piece (110) via the proximal implant end (201); and the guidewire (101) passes through the tube cavity of the lung volume…
