The proposed stomatological instrument end unit comprises a handle inside the housing of which is fitted a rotating sleeve (15) on one end of which is mounted a worm wheel (16) of a worm pair, a bevel toothed transmission gear (18) being mounted at the other end to transmit the rotation of the head (4) by means of a pivot pair (8) with spherical contact surfaces to ensure small gaps and thus ensure very precise alignment of the head (4). Inside the head is provided a holder (5) for the operating element (6) and a drive for rotating it in the form of, for example, a miniature turbine (14) which is made to rotate by compressed air fed along a channel (12). The proposed stomatological instrument end unit is convenient to use. |
