Pixee Medical is developing a new generation of computer assisted surgery tools using augmented reality and mixed reality. A simple pair of smart glasses allows the navigation of prostheses without percutaneous bone reference, nor associated consumable. Our dedicated instrumentation automatically transfers essential anatomical landmarks to the software. The surgical parameters are then displayed on a virtual screen combining real and virtual images. To do this, our company has developed proprietary software tools to use the simple camera from glasses to accurately locate bone structures and instruments. Our customizable workflows provide the surgeon with assistance tailored to their needs without wasting time. Our products are affordable and without disposable.
