An electrically operated handpiece for use in surgical and dental work adapted to be assembled to a micromotor by a slip-sleeve is described. The assembly is provided with a tubular body, fitting around the slip-sleeve. Fastening means are provided for releasably securing the handpiece to the micromotor. A resilient protective sleeve extends over the tubular body as well as at least part of the motor to prevent contact between the micromotor and the hands of an operator. |
