Medical or dental handpiece with inductive coupling

A medical or dental handpiece with dual data transfer capabilities, comprising:

• an outer shell;
• a tool receiving device capable of receiving a treatment tool, the tool receiving device being positioned within the outer shell and drivable to impart motion to a received treatment tool;
• a coupling device capable of coupling the handpiece to at least one of data and electrical power connections of a control and/or power supply unit;
• a memory unit connected by at least one optical or electric line to the coupling device, wherein the memory unit comprises a memory element for storage of at least one of handpiece operational data and handpiece identification data;
• a coil on the handpiece and operatively connected to the memory unit, wherein at least one of power for the memory unit, handpiece operational data and handpiece identification data, is inductively transferable via the coil provided on the handpiece or transferable via the at least one optical or electric line in a hardwired process.

A medical or dental handpiece comprising:

• an outer shell;
• a connecting device for connection of a treatment tool which is arranged in the outer shell and inducible to a driving movement;
• a coupling device for connection of the handpiece to a control and/or power supply unit;
• and
• a coil arranged at or adjacent the connecting device, said coil being configured for inductive coupling with a memory unit of the treatment tool comprising a treatment tool coil for storage of tool-related data, wherein
• the coil is electrically connected to a memory element provided in the handpiece for storage of handpiece-related data, so that the tool-related data and the handpiece-related data are transferable between the coil and a reading and/or sending device inductively couplable to the coil.
