The cortical bone trephine is a special veterinary surgical instrument used to remove cylindrical plugs of cortical bone (dense outer layer of bone). It is useful in various veterinary specialties, primarily neurosurgery (craniotomy and brain biopsy) and orthopedics (bone biopsy and joint surgery).

The sharp teeth of the trephine help cut through the dense cortical bone efficiently, while the T handle provides control and stability during drilling. Additionally, the cylindrical cutting head is available in various diameters and depths to match the desired bone core size.
