A stereotactic apparatus including a support slide for being slidably mounted to an arc, a microdrive unit having an instrument holder for depth adjustment of an instrument along a depth axis, in an essentially arc parallel plane, an arc perpendicular adjusting mechanism for adjustment of the microdrive unit along an arc perpendicular axis, an arc parallel adjusting mechanism for adjustment of the microdrive unit along an arc parallel axis, wherein the arc perpendicular adjusting mechanism includes an arc perpendicular slide, which is movably mounted to the support slide. The arc parallel adjusting mechanism is mounted at an end of the arc perpendicular slide, so that by movement of the arc perpendicular slide in a direction along the arc perpendicular axis the arc parallel adjusting mechanism also moves in that direction. An arc parallel slide is movably mounted to the arc parallel adjusting mechanism, the arc parallel slide being positioned at a different level with respect to the arc perpendicular slide, and the microdrive unit is rigidly mounted with its top portion to the arc parallel slide, and by movement of the arc parallel slide in the arc parallel direction the microdrive unit also moves in the arc parallel direction. |
