Abstract
The invention relates to a medical or dental-medical treatment instrument ( ) having a rod-like handpiece ( ) with the forward end region of which a tool ( ) can be releasably coupled by means of a tool coupling ( ), and the rearward end region of which can be releaseably coupled with a connection part ( ) by means of a handpiece coupling ( ), preferably a plug-in/turn coupling, the handpiece having: a grip sleeve ( ) which forms an outer body of the handpiece ( ), an oscillatory rod ( ) which extends longitudinally in the grip sleeve ( ) and is mounted therein radially or also axially elastically yieldingly, an in particular pneumatic oscillation generator ( ) for transmitting oscillations to the oscillatory rod ( ), and a sleeve ( ) surrounding the oscillation generator ( ). For reducing noise emissions, the sleeve ( ) is of elastically compressible or sound-absorbing material.
