BOHRERFÜHRUNGSANORDNUNG

摘要

An orthopaedic drill guide assembly (16) for guiding a drilling tool into a bone in orthopaedic surgery, which comprises a housing (134) which can be fastened to the bone and a drill guide block (20) which can be fastened to the housing. The drill guide has an array of at least two closely spaced drill guide bores (50-56) which define bone tissue which can be drilled by a drill bit extending through the bores towards the surface of the bone. The ratio of the distance between the centres of two adjacent ones of the bores to the sum of the radii of those bores is not more than about 1.5.
