Inferior nanometer list cell movement control system based on water pressure

The utility model discloses an inferior nanometer list cell movement control system based on water pressure. The support frame vertical fixation is on the workstation, and sliding ruler installs in the support frame side, and u -shaped frame passes through the third keysets to be fixed on sliding ruler 's mobile station, be equipped with liquid container in the frame, two thread turn of its upper cover connect and connect the two -port valve through medical silicone tube respectively, and ware one end is held to visiting needle holder to the 3rd thread turn articulate of its lower cover, and the other end is equipped with the probe, visiting needle holder and holding the ware card and visiting in needle holder holds the spring clamp slot of ware anchor clamps, these anchor clamps are fixed to unipolar ya nami positioning system side through first keysets to fix on the platform is grasped a little to the three -dimensional through the second keysets. The triaxial precision~7nm of this system, unipolar stroke 20mm, cell control is stable, and is little to the living cell damage, 0.05 nanometer of unipolar ya nami positioning system closed loop precision, the stroke is 12 microns, an experimental system that is used for unicellular accurate motion control and easily integrates based on unicellular little behaviour.
