Abstract

The present invention relates to a percutaneous calcific deposit removal device, the device having the advantage of being capable of crushing and suction of calcified substances simultaneously. Particularly, there is the advantage of being capable of suction to directly remove crushed calcified substances only through rotation of a motor by a mechanical structure of an inner needle comprising a spiral thread, without the need for a separate suction device.
