Open the CIPO recordAbstract From the Canadian patent
A shielded reciprocating surgical file system (10) is used for precisely removing bone or tissue material. The system allows a user to maneuver the system and navigate into hard to access sites under a direct vision mechanism (32) included in the system. A transmission mechanism (80) converts rotary motion from a motor into reciprocating motion and provides it to the surgical file for precision bone and/or tissue removal. A pulsatile pump (290) is operatively coupled with the transmission mechanism and provides irrigating fluid to the surgical site.

Why it's free to use
- Filed September 29, 2003 and granted May 15, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 29, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 29, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
