Abstract: An interlocking collet system includes an attachment comprising first and second attachment surfaces spaced from one another and a collet. The collet comprises a housing configured to extend along an axis. The housing defines a bore for selectively disposing and retaining the attachment therein in an installed position. First and second locking members are disposed within the bore and are moveable. At least one bias member is disposed within the bore and is arranged to position the first locking member in a first position in which the first locking member is configured to contact the first attachment surface. The at least one bias member is arranged to position the second locking member in a second position in which the second locking member is configured to contact the second attachment surface. The first and second locking members are configured to exert opposing axial forces on the attachment.

Abstract: A surgical driving system includes a driver and a cutting accessory. The driver includes a body driven by a motor. First and second arms project from the body, each arm having its own alignment tip. The arms define a channel between each other. The alignment tips are offset. Each tip includes two alignment surfaces facing away from each other. The cutting accessory includes a distal portion having a cutting tip and being coupled to a tool shaft. A proximal portion of the cutting accessory is coupled to the tool shaft and received within the channel. The proximal portion has a drive section with a flat to engage the arms of the driver. The proximal portion also has an alignment section separate from and proximal to the drive section to engage the alignment tips of the driver to orient the drive section relative to the arms.
