Medical instrument

An ophthalmic surgery support comprising a moving mechanism for holding a surgical instrument to be movable in Z-axis direction, a tilting mechanism for holding the moving mechanism so that a surgical instrument can be tilted in an arbitrary direction about a specified point that is to be positioned to a wound opening and positioned on the Z-axis, and a tilt fixing mechanism for fixing the tilt of the surgical instrument by the tilting mechanism, wherein the tilting mechanism has a rough-motion tilting mechanism, a fine-motion tilting mechanism finer in tilting range than the rough-motion tilting mechanism, a tilt switching mechanism for switching the tilt of the surgical instrument by the rough-motion tilting mechanism to that by the fine-motion tilting mechanism, and a resistance imparting means for imparting resistance for damping the tilting operation of the surgical instrument by the fine-motion tilting mechanism than that by the rough-motion tilting mechanism.
