12. A medical instrument comprising:
-
an instrument body having an outer surface, a recess provided in said instrument body including a collar having a length LK and a width BK forming an undercut in at least one partial region of the recess, said recess having a length LH and a width BH, where LH is greater than LK and BH is greater than BK; a wireless readable data carrier embedded in said recess, said data carrier having a length LT, where LT is less than LK, wherein said wireless readable data carrier comprises a transponder and an antenna for receiving and sending electromagnetic interrogation and answering signals; and an embedding medium inserted into said recess and surrounding said data carrier such that a rigid body is formed by means of which said data carrier is non-removeably held in said undercut as a unitary rigid structure; said embedding medium selected from the group consisting of;
epoxy resin or other duroplastic synthetic materials, cement, ceramics and combinations thereof. - View Dependent Claims (13)
