    摘要： 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.

    摘要： A robot head, for example for use in surgery, provides a back-drivable system allowing a surgeon to closely control the position of a cutter or other tool. The cutter is mounted at the end of a telescopic arm (20) which can be rotated about two independent perpendicular axes. Rotation about each axis is controlled by a separate motor (30′) which turns a lead screw (32). A bearing (34) travels along the lead screw and changes the angle of an offset crank (36) to cause the required rotation about the axis. The current rotational position about each axis is determined by a sensor at the output. A second sensor independently determines the position of the corresponding motor (30) and the two measured positions are compared. If they differ, the power to the cutter is immediately switched off.
