Abstract From the Canadian patent

An interactive system for guiding the use of a surgical tool uses at least one imaging technique such as CT, scanning. A mechanical arm has a fixed base at a first end and a tool holder that holds the surgical tool at a second end. A display displays one or more images from the image space of a patient's anatomy. A computer is coupled to the display and the mechanical arm. The computer tracks the location of the surgical tool through physical space performs a transforming rotation of the physical space to the image space, and causes the display to display the location of the surgical tool within the image space.

Why it's free to use

  • Filed November 6, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 6, 2010.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 6, 2012.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
