Claim 1:
2. A device for implementing a method for assisting a surgeon fit a prosthesis between at least two bones of a patient for hip, knee or shoulder arthroplasty, comprising:
at least three 3D markers, including two 3D markers, each configured to be affixed to one of the at least two bones, each 3D marker being a cube with each face being identified by a QR code, each 3D marker associated with a surgical screw configured to lock the respective 3D marker in a single position,
a data processing and recording unit,
a mask comprising an autonomous energy source,
a camera,
a communication device configured to provide short-range exchange with said data processing and recording unit,
a transparent screen for displaying images and information transmitted by said data processing and recording unit so as to provide overlaying of a real image visible in transparency and virtual images and information displayed on the screen as an augmented realty display,
wherein the camera is arranged, when the mask is in use, to recognize the 3D markers,, wherein the data processing and recording unit is configured to determine and record a 3D position of the centers of each 3D marker attached to the bones and to position and freeze, on the transparent screen, the centers of the 3D markers, the center of one of the 3D markers constituting the origin of an orthonormal frame of reference.
