ABSTRACT:
This invention relates to a new displacement equipment installed in air-turbine or contra dentistry drilling machines, used by the dentist in cutting treatment. By installing the equipment of this invention at the base of common cutting machines, the dentist can move the cutting machine while removing oral cavity organs when necessary with one-hand finger operations, during utilization inside the oral cavity. It is basically formed by the installation member with hole, through which the base of the dentistry drilling machine is inserted and is fixed in a constant position, by the arm installed in the supporting hole of the installation member, and by the displacement plate, installed on the tip of the arm. The arm, installed on the tip of the displacement plate, is formed by many arms number which can rotate in the horizontal and vertical directions according to the user's finger articulations. The function of the tip of the tip arm, which can move in the vertical direction, is to form the shape of the tip of the instrument to be inserted into the oral organ. The function of the medium arm and others is to hold the oral cavity organs located on the side of the tool, such as lips, tongue, masseter, lower maxilla lower protuberance, etc. Furthermore, by constructing it so that the installation member does not separate from the cutting machine, and permitting the cutting machine to freely rotate around the axis, or by installing the installation member in the cutting machine so as to allow floating, it is possible to apply a strong pressure with the tip of the arm or the displacement plate with any finger to hold oral cavity organs during operation inside the oral cavity, while handling the cutting machine freely with other fingers.
