This periosteal elevator is a dedicated tool for periosteal dissection in UBE minimally invasive spine surgery. The wavy anti-slip texture on the grip ensures stable fingertip control and prevents slipping during separation work. Its ultra-thin flat blunt tip lifts the periosteum covering lamina and facet joints completely. Blunt dissection avoids tearing soft tissue or scratching bone. The ultra-slim long shaft fits dual-channel minimally invasive incisions perfectly, reaching deep surgical areas to peel periosteum and separate soft tissue, creating a clear view for subsequent bone grinding and decompression. Made of stainless steel, it can undergo repeated high-temperature sterilization.
