Abstract
A device for attaching a localization marker to the lower jaw of an individual. The marker includes an inner face provided with two attachment lugs including an intra-oral portion having a general U-shape adapted for coming into contact with the outer face of the teeth of the lower jaw, an extra-oral portion including an attachment element for the marker, a connecting portion connecting the intra-oral portion and the extra-oral portion. The attachment element includes two recesses each adapted for receiving a respective lug of the marker, the recesses being separated by a tab adapted for being elastically deformed when one of the lugs is engaged in a respective recess so as to exert a pressure force on the lug.
Claims18
A localization device, comprising:
- a localization marker comprising an inner face provided with two attachment lugs, and
- a device for attaching the localization marker to a lower jaw of an individual, comprising:
- an intra-oral portion having a general U shape adapted for coming into contact with an outer face of teeth of the lower jaw,
- an extra-oral portion comprising an attachment for the marker, and
- a connecting portion connecting the intra-oral portion and the extra-oral portion,
- wherein the attachment comprises two recesses each adapted for receiving a respective lug of the localization marker, said recesses being separated by a tab adapted for being elastically deformed when one of the lugs is engaged in a respective recess so as to exert a pressure force on said lug,
- the localization marker being attached to the extra-oral portion by engagement of each lug in a respective recess, the tab exerting a pressure force on one of the lugs, and
- the localization marker comprising a plurality of reflective patches or beads.
