Device and process for calibrating geometrical measurements of surgical tools and orienting the same in space

A device (1) for calibrating geometrical measurements of surgical tools (10) and orienting the same in space, the device (1) comprising:

• A) a docking station (2) having two fixed jaws (3) and a surface (21);
• and
• B) at least three marking indicators (9) arranged on the docking station (2) in a fixed manner, said at least three marking indicators (9) being measurable in reference to spatial position electromagnetically or acoustically through a position detector (14) in order to determine the position and orientation of the device (1) in space,
• C) wherein the two jaws (3) extend perpendicularly from the surface and are locked to the docking station (2) in an immovable manner and thus remain stationary with respect to the surface (21) of the docking station (2) such that the surface (21) and lateral walls (40) of the two jaws (3) define a passage (18) for receiving a surgical tool;
• D) wherein the two jaws (3) are, at least on surface portions opposite to each other, conformed in a round cylindrical, hyperboloid or double-cone shaped fashion such that a surgical tool (10) can be laid down between the two jaws (3) so as to make contact with at least one contact point of each of the two jaws (3) across a longitudinal axis (11) of the surgical tool (10),
• E) wherein the device (1) further comprises a rotary table (6) placed within the surface (21) of the docking station and having two clamping jaws (5) mounted above the surface (21), the rotary table (6) having an axis of rotation (25) that extends vertically from the surface (21) such that the clamping jaws can be rotated with the table to hold the surgical tool;
• and
• F) wherein the two lateral walls (40) or the surface (21) or the rotary table (6) have a form comprising at least two additional points of contact for contacting a surgical tool (10) inserted between the two fixed jaws (3) across a longitudinal axis (11) of the surgical tool (10), so as allow a lateral docking, defined with respect to the marking indicators (9), of the surgical tool (10).
