Abstract

An instrument includes a motor unit with a slide or piston. The operating direction of the slide or piston may be adapted to the bending and stretching movement of the user's index finger. A resiliently elastic extension or tongue transfers the bending and stretching movement of the index finger to the slide or piston on the side of the motor unit. The tongue is fixedly coupled to the slide or piston and extends above the handpiece along a gripping portion. The resilient flexibility of the tongue is selected so that it can be easily bent by the index finger resting on the tongue toward the gripping portion of the handpiece, which then serves as a contact or stop element for an operating element at the tongue and thus ensures fixed clamping of the handpiece between the thumb, the middle finger and the index finger.
