Abstract
An adjustable collet mechanism for a surgical handpiece which enables the surgical tool driven by the handpiece to be oriented at selected angular positions relative to the handpiece axis. The coupling means includes a non-rotatable sleeve attached to the handpiece and a rotatable sleeve attached to the collet holding the surgical tool. The abutting faces of the non-rotatable and rotatable sleeves are angled relative to the handpiece axis so that relative rotation of the components causes their axes to be positionable either in alignment or at a predetermined angular orientation. The coupling mechanism includes a tubular coupling link which enables relative rotation between the rotatable and non-rotatable sleeves while also enabling translation of power from the handpiece to the surgical tool.
