  • Micromanipulator for inverted-design microscope
    Patent number: 4749270
    Abstract: A micromanipulator for an inverted design microscope comprises a needle carrier disposed between a stage and a condenser lens of the microscope for carrying a glass needle in the direction of an optical axis. It also includes a centering mechanism which causes a displacement of the glass needle in a plane orthogonal to the optical axis, a hydraulic drive mechanism disposed on the upper surface of the stage for supporting the needle carrier to cause a vertical movement of the glass needle carried by the carrier along the optical axis, and a hydraulic operator connected to the hydraulic drive mechanism through a hydraulic transmission tube.
