A device is provided for radially strengthening a polylactic acid tube, which includes a tubular mold, a rotating blade and a distal blade, wherein a rotating shaft of the rotating blade is arranged at an axial position of the tubular mold, a first end of the distal blade is movably connected to the rotating blade, and a second end of the distal blade is controlled by a control rod so as to open and close the distal blade. A strengthening method is provided, in which the device for radially strengthening a polylactic acid tube is used. The method includes loading a polylactic acid tube to be strengthened into the strengthening device, heating the strengthening device for a first preset time, rotating the rotating blade in a constant direction while opening the distal blade at a first speed such that the second end of the distal blade approaches the tubular mold, closing the distal blade and restoring the distal blade to an initial state after squeezing and scraping for a second preset time, cooling the strengthening device to room temperature, taking out a strengthened polylactic acid tube, and cutting off redundant sections. The tube strengthened by the above-mentioned strengthening device and method has a better wall thickness uniformity, more precise inner and outer diameter dimensions, with no axial orientation, and no thermal creep in a low temperature range such as body temperature, etc.
