Registration and identification tool and method for a dental and/or cranio-maxillofacial surgical instrument and/or general surgical instrument

A navigation system for dental and/or cranio-maxillofacial and/or general surgery, comprising:

• a registration and identification tool for a dental and/or cranio-maxillofacial surgical instrument and/or general surgical instrument, including:
• a body,
• a marker member which is optically detectable, the marker member being-provided on the body, and
• a recess in the body which extends from an outer surface of the body into the inside of the body, thereby defining an extension direction of the recess, wherein
• the recess has a shape such that a lateral extension of the recess decreases in the direction from the outer surface of the body towards the inside of the body,
• the surgical instrument, and
• an imaging unit which is movably attached to the surgical instrument.

A method for registration and/or identification of a dental and/or cranio-maxillofacial surgical instrument and/or general surgical instrument using a registration and identification tool including a body a marker member which is optically detectable, the marker member being provided on the body, and a recess in the body which extends from an outer surface of the body into the inside of the body, thereby defining an extension direction of the recess, wherein the recess has a shape such that a lateral extension of the recess decreases in the direction from the outer surface of the body towards the inside of the body, the method comprising:

• placing a surgical tool of the surgical instrument into the recess of the registration and identification tool,
• pivoting the surgical instrument relative to the marker member while the surgical tool is placed inside the recess,
• performing a detecting process of the relative movement of the surgical instrument, and
• identifying geometrical characteristics of the surgical tool and/or registering the relative position of the surgical tool to the remainder of the surgical instrument using the results of the detecting process.
