Abstract
A machine for forming threads in a cylindrical bone dowel made of bone material, comprising a planar surfaced base provided with a threaded guide member having an externally threaded portion. A holding and rotating assembly is mounted on the base to rotatably hold the bone dowel so that the central axis of the bone dowel extends in the axial direction of the threaded guide member, An essentially planar support member is mounted on the guide member for movement with respect to base and an angle adjustment assembly is mounted to the support member. A cutting assembly having a cutting member in the form of a burr is also mounted on the support member so that when the threaded guide member is rotated the cutting assembly and associated cutting member is carried by support member to engage the bone dowel. A timing assembly is connected to the threaded guide member and the holding and rotating assembly so that when the cutting member moves along the bone dowel in an axial direction, the holding and rotating assembly rotates the bone dowel allowing a thread of a predetermined depth and configuration to be cut into the bone dowel.
