System for navigation-assisted shoulder operations and navigation method for positioning navigated treatment apparatuses with respect to a bone |
摘要 |
The present application relates to a system for navigation-assisted shoulder operations in which the humeral component is partially replaced with a prosthesis, comprising: a first tracking unit which is configured to be fastened to a section of a bone which is to be removed during the operation; a detection unit which is configured to detect landmarks on the bone; a second tracking unit which is configured to be attached to another section of the same bone; a camera unit which simultaneously detects the first and second tracking unit, in order to determine their respective location; and a computational unit which is connected to the camera unit and is configured to: determine a first relative location of the landmarks relative to the first tracking unit from data acquired by means of the detection unit; and calculate a second relative location of the landmarks relative to the second tracking unit on the basis of the first relative location; such that additional navigated treatment apparatuses can be exactly positioned during the operation by referring to the second tracking unit. |
