1. An oscillatory medical and/or dental instrument system comprising:
- a grip sleeve;
a bearing sleeve longitudinally received in the grip sleeve and coupled thereto;
a hollow first oscillatory rod longitudinally received in the bearing sleeve and coupled thereto, the bearing sleeve elastically coupling the first oscillatory rod to the grip sleeve to permit oscillatory movement of the first oscillatory rod with respect to the grip sleeve;
an oscillation generator coupled to the first oscillatory rod and disposed within the bearing sleeve for transmitting oscillator movement to the first oscillatory rod;
the first oscillatory rod comprising a hollow base end coupled to a hollow first attachment part;
a tool longitudinally received in the first oscillatory rod and coupled thereto and extending through the first attachment part.

Abstract
The invention relates to a medical or dental-medical treatment instrument (1) having a grip sleeve (11), an oscillatory rod (13) which extends longitudinally in the grip sleeve (11) and is mounted therein in a radially or also axially elastically yielding manner, and an oscillation generator (31) for transmitting oscillations to the oscillatory rod (13). In order to attain a compact construction, the oscillatory rod (13) is of a base part and an attachment part which is fixed on the base part.
