发明名称 THIGMOTACTIC SURGICAL METHOD AND THIGMOTACTIC SURGICAL DEVICE
摘要 A stereotactic surgery frame with x-ray detectable fiducial markers (100, 102, 104) is presented. The frame is fixed with respect to a patient's anatomy and defines a predetermined three-dimensional coordinate system (X, Y, Z) in which surgical devices may be precisely positioned. A desired target area (170) of the anatomy is detected in a cross-sectional CT scanner depiction of the combined stereotactic frame and patient anatomy. The target's X, Y, Z coordinates with respect to the frame are calculated based on three non-collinear fiduciai points (F1, F2, F3) locaded within the cros-section and having known coordinates both with respect to the frame and with respect to the target. Thus, the surgical device can be precisely applied in the target area.
