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.

Claims

1. 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),

characterised in that,

the oscillatory rod (13) is of a base part and an attachment part (61) which is fixed on the base part.

2. Medical or dental-medical treatment instrument according to claim 1,

characterised in that,

two or more oscillatory rods (13) of different masses are provided, which are selectively installable or exchangeable.

5. Medical or dental-medical treatment instrument according to claim 1 or 4,

characterised in that,

the attachment part (61) has a greater density than the base part.

6. Medical or dental-medical treatment instrument according to claim 1 or 4,

characterised in that,

the attachment part (61) is arranged in the rearward end region of the base part.

7. Medical or dental-medical treatment instrument according to claim 6,

characterised in that,

the attachment part (61) projects rearwardly beyond the base part.

8. Medical or dental-medical treatment instrument according to claim 1 or 4,

characterised in that,

the base part is a sleeve and the attachment part (61) is emplaced in the sleeve with a sleeve section.

9. Medical or dental-medical treatment instrument according to claim 8,

characterised in that,

the attachment part is a sleeve.

10. Medical or dental-medical treatment instrument according to claim 1 or 4,

characterised in that,

the cross-sectional dimension of the attachment part (61) corresponds to the cross-sectional dimension of the base part.

11. Medical or dental-medical treatment instrument according to claim 1 or 4,

characterised in that,

there are available prefabricated, in the workshop or for the user, a plurality of base parts and/or attachment parts (61) of different masses.

12. Medical or dental-medical treatment instrument according to claim 7,

characterised in that,

the fixing of the attachment part (61) is releasable.

3. 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),

characterised in that,

two or more oscillatory rods (13) of different masses are provided, which are selectively installable or exchangeable.

4. Medical or dental-medical treatment instrument according to claim 3,

characterised in that,

one or both oscillatory rods (13) is or are of a base part and attachment part (61) connected therewith, which is fixed non-moveably on the base part.
