Abstract: A powered surgical handpiece that includes a motor for actuating a cutting accessory. The handpiece has a housing with a bore for receiving the cutting accessory and a coupling member internal to the bore that releasably engages and actuates the cutting accessory. A coil is mounted to the housing adjacent the bore. More particularly, the coil is located so that when the cutting accessory is seated in the bore, the coil is able to exchange signals with a complementary coil integral with the cutting accessory. A locking assembly mounted to the housing releasably holds the cutting accessory in the bore.

Abstract: A surgical tool system with a handpiece that has an internal power generating unit used to actuate an accessory attached to the handpiece. Power to actuate the handpiece comes from a control console. Internal to the accessory there is an identification chip that describes the operating and/or physical characteristics of the accessory. Complementary coils in the handpiece and accessory facilitate the reading by inductive coupling of the data in the accessory. The data in the accessory are inductively read by the control console through the handpiece. Based on the read data, the control console actuates the handpiece in an appropriate manner for the attached accessory. The accessory data and data inductively read from an implant the accessory is used to set are supplied to a surgical navigation unit. The surgical navigation unit, based on these data, tracks and indicates the position of the implant as it fitted in the patient.

Abstract: A system and method for fixating uses a cranial disk clamp. The cranial disk clamp includes a lower disk, an upper disk and a stem. The lower disk has an inner surface and an outer surface. The stem has first and second ends and an engaging portion between the first and second end. The stem is connected to the lower disk at the first end and extends away from the inner surface of the lower disk. The upper disk has a clamping element for releasably engaging the stem.
