Insert assembly with radiofrequency identifier for medical device

A medical device comprising a control unit, a handpiece provided with a handpiece antenna and an insert assembly with radiofrequency identifier, said insert assembly being configured to be inserted in the handpiece of the medical device, said insert assembly comprising:

• an insert adapted to interact with a part of a patient's body, the insert comprising an insert metal tang;
• a ferromagnetic layer arranged in contact with said insert metal tang of the insert, wherein said ferromagnetic layer comprises ferromagnetic material;
• a dielectric layer arranged in contact with said ferromagnetic layer;
• an insert antenna arranged in contact with said dielectric layer, and comprising an insert antenna metal element extending along a predefined substantially planar profile, said predefined substantially planar profile, as a whole, wraps, at least partially surrounding said insert metal tang, said insert antenna being configured to receive and transmit electromagnetic fields within a given frequency range, modulated or not modulated;
• and
• an identification chip operatively connected to said insert antenna, said identification chip being configured to transmit, when activated, information relating to the insert assembly;
• wherein said ferromagnetic layer is adapted to reduce or cancel phenomena of attenuation and/or distortion of an electromagnetic field, caused by field parasitic effects in a vicinity of the insert antenna due to interaction of a transmitted or received electromagnetic field with at least one of metal parts of the insert metal tang, liquids present in the insert, the insert antenna metal element,
• and wherein said ferromagnetic layer, dielectric layer and insert antenna form a transceiver device configured to put in wireless communication said identification chip with the handpiece antenna of said handpiece, said insert assembly being operatively and mechanically connected to said handpiece of the medical device, and wherein said insert antenna is configured to communicate wirelessly with said handpiece antenna.
