Medical | Science | Facts on Instagram: "A medical cast saw uses an oscillating blade that moves back and forth very rapidly, rather than spinning. This motion allows it to cut through hard, rigid materials like plaster or fiberglass, which resist movement and get abraded. However, soft tissues like skin can move with the blade’s vibrations, so they absorb the motion without being cut. This clever design makes it safe for removing casts without injuring the patient.😳 . . . #trendingreels #didyo
