Insert assembly with radiofrequency identifier for medical device

A medical device comprising a control element, a medical device handpiece provided with a handpiece antenna for a transceiver device and an insert assembly comprising an insert and a radiofrequency identifier, said insert assembly being configured to be inserted in a medical device handpiece, wherein:

• said insert is adapted to interact with a part of a patient's body, wherein said insert comprises an insert metal tang;
• said radiofrequency identifier comprises:
• a ferromagnetic layer, arranged towards said insert metal tang, 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 planar profile, said predefined planar profile, as a whole, wraps, at least 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;
• an identification chip, said identification chip being operatively connected to said insert antenna and configured to transmit and/or receive, when activated, information about 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;
• wherein said medical device handpiece comprises a handpiece antenna;
• wherein said ferromagnetic layer, dielectric layer and insert antenna form a transceiver device configured to put said identification chip in wireless communication with said handpiece antenna;
• wherein said insert antenna comprises a first side or outer side of said predefined planar profile of said insert antenna metal element which faces away from said insert metal tang;
• wherein said insert antenna comprises a second side or inner side of said predefined planar profile of said insert antenna metal element which faces towards said insert metal tang;
• wherein said ferromagnetic layer and/or said dielectric layer comprises a chip seat;
• wherein said identification chip is operatively connected to said insert antenna to avoid protruding from at least said first side or outer side;
• wherein a portion of said identification chip protrudes with a chip portion from said second side or inner side, opposite with respect to said first side or outer side;
• and wherein said protruding chip portion is received in said chip seat, and
• wherein said insert assembly is operatively and mechanically connected to said medical device handpiece in a separable manner.
