Detachable support arm for surgical navigation system reference array

摘要

The structure (42) has a support structure engageable with an instrument in a predefined position. A reference array is connected to the support structure in another predefined position. The support structure has a predefined geometry of the reference array relative to the instrument in each of six degrees of freedom. Two mounting interfaces engage the support structure releasably with the instrument. An independent claim is also included for a method of preparing an instrument having a predefined geometry for registration in a computer assisted navigation system.
