摘要： The invention concerns a device for fixing instruments comprising a rotating shaft (5) designed to receive the instrument and drive same in rotation characterized in that it comprises: a device having at least one pin (11) elastically retractable perpendicularly relative to the axis of the instrument housing until it can be engaged in the catching groove (2) thereby causing the instrument to be axially retained and a catch (13) secured in rotation to the rotating shaft and which in combination with the rotating shaft provides the shape combined with that of the drive flat (3) of the shank of the instrument which is adapted to be radially or longitudinally retracted if the flat is properly oriented and resumes the position in which it drives in rotation the instrument. The flat of the instrument being globally urged to take up the suitable position during rotation when the slightest rotational force is applied thereto. The instrument is released by the action of a push button (17) for example, which controls the radial spacing apart or retraction of the pin.

摘要： The invention relates to a root canal instrument handle of rotating endodontic type, for example a bur shank, comprising at its end, intended to engage in a driving assembly of the head of a headpiece or a counter-angle, an annular groove and a flat section to engage with an additional means for axial linkage and rotating links provided in the driving assembly, a handle characterized in that it is made up of two co-axial portions in which an internal part (3) and an external sleeve covering the internal portion at least on a portion of its length, a means being provided to fix the sleeve (2) to the external portion (3) in axial translation and rotation, in that it comprises translational and rotational blocking means to engage with a root canal instrument. To easily identify an instrument, it can be provided that for a given instrument, there is a match of a given combination of colors of the two portions of the handle.

摘要： The invention relates to a device for fixing a dental tool to a tool holder arrangement which rotatably fixes and actuates a dental tool or instrument around a drive shaft (6), is incorporated into a dental handpiece head (4) and is coupled to a movement transmission unit integrated into the arm of said handpiece. The inventive device is characterised in that it mainly consists of a deformable and elastic clamping-unclamping element which is embodied in the form of a belt (25), whose at least one part is provided with a section introducible into an annular throat or groove embodied in the top part of the tool and holding said tool by clamping forces and which is also provided with means for producing unclamping forces for cancelling clamping forces, thereby releasing the tool. In other variants, said elastic belt can be embodied in the form of a parallelogram or ring or split catch.
