Micromanipulator fine control apparatus

A micromanipulator fine control apparatus for finely controlling a microtool of a micromanipulator comprising:

• a first moving unit for sliding in the fore and aft directions, having a vertical through hole;
• an adjusting member having a screw part to be inserted into said through hole of said first moving unit, and a fixed ball on said screw part;
• a second moving unit for sliding in the left and right directions, having a vertical through hole;
• a movable ball rotatably supported by said through hole of said second moving unit, said movable ball having a control handle projecting upwards and a cylindrical inner surface, said cylindrical inner surface being in contact with an outer surface of said fixed ball;
• a base plate for slidably supporting said first and second moving units in the corresponding directions;
• a supporting ball having a through hole, for supporting the upper portion of said control handle inserted into said through hole of said supporting ball;
• a horizontal movement operating means including a tapered hollow having an opening disposed towards the base plate, and a through hole at the top of said hollow, said horizontal movement operating means being horizontally slidable on said base plate above an upper surface thereof, said horizontal movement operating means being for rotatably supporting said supporting ball at said through hole at the top of said hollow;
• a fore and aft fine control liquid-operated means provided between said base plate and said first moving unit, said fore and aft fine control liquid-operated means having a first liquid-operated cylinder coupled to a fore and aft fine control liquid-operated cylinder of said micromanipulator with a first hose, and a first piston movably fitted to said first liquid-operated cylinder, said fore and aft fine control liquid-operated means for varying the amount of liquid of said first liquid-operated cylinder by moving said first moving unit;
• and
• a left right fine control liquid-operated means provided between said base plate and said second moving unit, said left right fine control liquid-operated means having a second liquid-operated cylinder coupled to a left right fine control liquid-operated cylinder of said micromanipulator with a second hose, and a second piston movably fitted to said second liquid-operated cylinder, said left right fine control liquid-operated means for varying the amount of liquid of said second liquid-operated cylinder by moving said second moving unit;
• when said horizontal movement operating means is moved to the front, rear, left and right, said control handle being tilted to the front, rear, left and right, respectively;
• said first moving unit and said second moving unit being moved;
• the amount of liquid in said first liquid-operated cylinder being varied by said fore and aft fine control liquid-operated means;
• the amount of liquid in said second liquid-operated cylinder being varied by said left right fine control liquid-operated means;
• said microtool being finely moved in the same direction as the moving direction of said horizontal movement operating means.
