Trephine

The Trephine is a precision hollow cutting instrument for bone coring, bone biopsy, and creating access through bony structures in minimally invasive and endoscopic surgery. It comes in three sizes, 8.0 mm and 6.5 mm in diameter, with working lengths of 118 mm, 168 mm and 350 mm for both shallow and deep surgical sites.

The distal end has a sharp, crown-shaped serrated cutting edge, with 18 teeth on the 8.0 mm sizes and 12 teeth on the 6.5 mm size. When rotated, the teeth cut cleanly and efficiently through bone and remove a cylindrical core with minimal trauma to the surrounding tissue. The hollow shaft holds the cut core, so the sample can be retrieved intact.

Laser-etched depth markings run along the shaft in 5 mm steps up to 100 mm. They show exactly how deep the trephine has gone, which helps the surgeon cut to a controlled, measured depth and adds safety near sensitive structures. The proximal end has a hexagonal coupling for connecting a trephine handle. The trephine is made from high-grade surgical stainless steel, so it is durable, corrosion-resistant, and can be autoclaved for repeated sterilization.
