Title: PASSIVE DEVICE FOR LOCATING AN OBJECT
Abstract:
The invention concerns a device comprising superposed: a support (1), a reflecting film (2) and a thin open-worked metal plate (3) partially covering the film so as to constitute markers, and a magnet (4) preferably enclosed in a sealed housing (8) of the support to attract the metal plate against the support. Thus, the film is easily removed before the device is sterilised when it is used for locating a computer-assisted medical or surgical instrument. For example, the device is a clip fixed on an instrument, a nasal support or a probe whereof the positioning is controlled on a monitor screen.
