INSERT ASSEMBLY WITH RADIOFREQUENCY IDENTIFIER FOR MEDICAL DEVICE

An insert assembly, insertable in a handpiece of a medical device, has an insert having an insert metal tang, a ferromagnetic layer in contact with the insert metal tang, a dielectric layer in contact with the ferromagnetic layer, an insert antenna in contact with the dielectric layer, having an insert antenna metal element and configured to receive and transmit electromagnetic fields, and an identification chip operatively connected to the insert antenna and configured to transmit information about the insert assembly. The ferromagnetic layer reduces or cancels attenuation and/or distortion phenomena of an electromagnetic field caused by parasitic effects due to interaction of a transmitted or received electromagnetic field with metal parts of the insert metal tang, liquids present in the insert, and the insert antenna metal element. The ferromagnetic layer dielectric layer and insert antenna form a transceiver device putting the identification chip in communication with a handpiece antenna.
