Insert assembly with radiofrequency identifier for medical device

An insert assembly has an insert having an insert metal tang, and a radiofrequency identifier having a ferromagnetic layer in contact with the insert metal tang and including ferromagnetic material, a dielectric layer in contact with the ferromagnetic layer, an insert antenna in contact with the dielectric layer and having an insert antenna metal element extending along a planar profile for receiving and transmitting electromagnetic fields, and an identification chip operatively connected to the insert antenna for transmitting and receiving information about the insert assembly. The ferromagnetic layer reduces or cancels attenuation and/or distortion phenomena of electromagnetic fields. A transceiver device puts the identification chip in wireless communication with a handpiece antenna. The identification chip avoids protruding from a first or outer side of the planar profile. A part of the identification chip protrudes with a chip portion from a second or inner side of the insert antenna metal element. The chip portion is received in a chip seat.
