摘要:
A tool recognition system includes a tool and a dental drill. The tool includes a fluted portion and a shank portion. The tool has one or more colored identifiers at least partially circumscribing a part of the shank portion. The dental drill includes a tool rotating portion, a light transmitter located in the tool rotating portion, and a light sensor. With the tool removably coupled to the tool rotating portion, the one or more colors present a sequence of one or more colors to the light sensor for identifying the tool to the light sensor when the tool rotates a predetermined number of turns. The dental drill includes a handpiece and a console in another embodiment.
摘要:
The invention relates to a dental preparation instrument (1), comprising a tool (6) that rotates in an alternately reversible manner, wherein the preparation instrument (1) has a drive (2) for the tool (6). The drive (2) provides a continuous fully rotational motion (7), and a gearing (43) is arranged before the tool (6). Said gearing converts the continuous fully rotational motion (7) of the drive (2) into an alternately reversing rotational motion (8), which is continuous as viewed over several reversals.
