HANDPIECE HAVING AN ELECTRICAL CONNECTION MEANS

摘要

The invention relates to a dental handpiece (1), including: a head (2) suitable for driving a tool; a body (3) having a proximal section (4) extending in a longitudinal direction (l-l) and intended to be connected, by a proximal end surface (5), to a distal surface of a drive motor; an indexing means (8) suitable for rotatably positioning the body (3) of the dental handpiece (1) about the longitudinal direction (l-l) relative to the drive motor; an electric means (9) for lighting the working area of the tool; and a means (10) for supplying electric power to the electric lighting means (9). The indexing means (8) is retractable or set back from the proximal end surface (5), and the electric supply means (10) includes a retractable electrical connection means (11).
