A shaver is a powered surgical instrument that simultaneously cuts and removes tissue, bone, or cartilage from a surgical site. This instrument is widely used in arthroscopy, ENT, and neurosurgery to address conditions like torn menisci, damaged cartilage, or diseased tissue. The shaver features a rotating inner blade within an outer sheath, connected to a motor handpiece, and typically includes suction to remove debris. It is a modern alternative to manual instruments and is available in a range of sizes to suit different surgical applications.
