| 内容記述 | Object. Spatial perceptions by the naked eye and under the surgical microscope were compared between groups of experienced and inexperienced neurosurgeons to understand distortion in the three-dimensional recognition of the surgical field. Methods. A phantom surgical field containing a start point, arbitrarily set virtual gate, and a target point was fixed under a video-see-through microscope which allows projection of navigational image into microscopic view. The surgical navigator was used to record the spatial position of the suction tip. Examinees were first shown the position of the invisible virtual gate. Then they were asked to point consecutively to three points with the suction tip under four different visual conditions; by the naked eye, under the microscope, while watching a navigator monitor, and under the microscope with projection of navigational image. The pointing deviation from the suction tip to the virtual gate, the trajectory of suction tip and the operation time were evaluated. By the naked eye, pointing accuracy did not differ between the two groups. However, accuracy under the microscope was significantly worse in inexperienced group. Further analysis demonstrated that these differences were attributable to inaccurate depth perception. With the navigational image projection, the accuracy and the operation time were significantly improved in both groups. Conclusions. Under the microscope, the spatial perception was considerably distorted, especially in the depth component. Application of the navigator improved this perception considerably. The navigational image projection into the microscope further improved spatial perception and lead to better visuomotor coordination under the microscope. | |||||||||
