The present application relates to a coupling device for a handle (3) of a medical tool (1) or medical power-tool chuck (30). The coupling device comprises a coupling-body (2) including a bore (6), a working axis (X) extending along said bore (6) and a seat (4) arranged at a first end (8) of said bore for receiving a tool-insert (10) with a central axis (Y) at an angle in reference to the working axis (X). The coupling-body (2) further comprises a protrusion (7) arranged within said bore (6), said protrusion (7) being configured to engage a groove (13) of the tool-insert (10) upon alignment of the central axis (Y) with the working axis (X). The engagement of the protrusion (7) with said groove (13) locks the tool-insert (10) within said coupling body (2).
A coupling device for a handle of a medical tool or medical power-tool chuck, comprising a coupling-body including a bore, a working axis extending along said bore and a seat arranged at a first end of said bore for receiving a tool-insert with a central axis at a non-zero angle in reference to the working axis, wherein the coupling-body further comprises a protrusion arranged within said bore, the protrusion being configured to allow the tool-insert to advance past the protrusion only when the central axis of the tool-insert is inclined relative to the working axis, and said protrusion being configured to engage a groove of the tool-insert upon alignment of the central axis with the working axis, wherein the engagement of the protrusion with said groove locks the tool-insert within said coupling body.
