Abstract
A surgical tool holder has a shank having a central axis, a first driveable end and second coupling end. The second end has a coupling device having interfaces each for mating with corresponding structures on the inside of a hollow reamer. The interfaces mate with centering structures at or near a base end of each tool, the tool being held in functional assembly to the shank by a releasable locking mechanism.
Claims11
A surgical tool holder comprising a shank having a central axis, a first driveable end and second coupling end, the second end comprising a coupling device which couples to a corresponding structure of a reamer tool and holds such tool in functional assembly to the shank by a releasable locking mechanism, the holder characterized by the fact that the coupling device has at least two pairs of bayonet interfaces spaced apart from the central axis, each interface comprising at least a portion of a slot having a two-tiered opening transverse to the central axis of a form so as to be able to receive corresponding elongated structures of at least two types of reamer tools, at the selection of the user, the corresponding structures being elongated in a direction substantially perpendicular to the central axis.
