This osteotome is specially designed for DELTA large-channel spinal minimally invasive surgery. Unlike standard small UBE osteotomes, its thicker metal shaft resists bending under tapping force. The solid wood grip delivers excellent shock absorption, cushioning vibrations from bone mallet strikes to reduce hand strain for surgeons. Its evenly sharpened blade cuts bulky hyperplastic bone and thickened lamina efficiently, perfectly matching decompression procedures with DELTA large working channels.
