Abstract
In a dental angular instrument holder (10) a turbine (142) for driving a clamping chuck (62) for an instrument (64) is installed in a handle part (12) and is supported on a drive shaft (70) passing through a neck part (14). Thedrive shaft is fixedly connected to the clamping chuck (62) via a 90.degree. direction-changing gear. The turbine (142) can have large radial dimensions, compared to a turbine installed in the working head (16) of the angular instrument holder, so that a greater torque can be exerted on the instrument (64). In addition the movement-changing gear (66, 68) is at the same time designed as a reduction gear.
Claims16
A dental angular instrument holder with a handle part, with a neck part and a holding part connected to the handle part by an elbow region in such a way that the neck part axis and the handle part axis abut one another at an obtuse angle, further comprising a working head that is provided with a clamping chuck for an instrument, and with a turbine engaging the clamping chuck, wherein the turbine is arranged in the elbow region and engages the clamping chuck via a drive shaft passing through the neck part.
