ABSTRACT:
An arrangement that may be used in combination with selected tools having a tooth cutting surface for the care and maintenance such as removing a selected portion of the exposed surface of equine teeth. The selected tool in communication with a source of powered motion and mounted in and supported by a hand piece which is guided into the mouth of the horse. The cutting surface of the powered tool is partially guarded so as to protect fleshy portions of the horse's mouth from being engaged by the cutting surface. The hand piece provides for quick on and off attachment of a selected cutting surface for maintenance of a preselected portion of teeth within the same hand piece or another hand piece sized to ease access to the next selected portion of the horse's mouth. The selected hand piece arrangement may further incorporate a vacuum channel whereby the tooth dust and debris created by the powered cutting surface removing a portion of tooth is sucked out of the mouth of the horse. The motion of the tooth surface removal tool may be changed from rotary to powered reciprocating motion for a selected portion of the teeth or changed to be at a preselected angle. Attaching the powered drive to the rotary cutting surface by means of an adjustable clutch further enhances protection from injury to the inside of the mouth of the horse.
