Acta Oto-Laryngologica, 1960
Not only a microscope of highest standard but also suitable fine operation instruments play a determining role in the modern oto-microsurgery. All surgeons agree with the statement that the principle cause of the failures is the weakness of the technical performance.—No matter how sensitive the human hand may be, it cannot stand comparison with an ...

Dynamics of Micromanipulation Using a Compliant Micromanipulator
Design Engineering and Computers and Information in Engineering, Parts A and B, 2006Attractive forces present at the micro and nano scales are a hindrance to error-free manipulation of micro-scale objects using manipulator devices as they cause the micro-scale objects to become adhered to the end-effector of the manipulator. This paper presents a dynamic model for controlled release of a polystyrene microsphere adhered to the end ...

Cooperative Micromanipulators for 3D Micromanipulation and Assembly
Volume 5: 6th International Conference on Micro- and Nanosystems; 17th Design for Manufacturing and the Life Cycle Conference, 2012In this paper we demonstrate coordinated control of multiple micromanipulators for use in automated 3D micromanipulation and assembly tasks. We build on our previous work on caging micromanipulation by using a similar methodology and extend it to the 3D case.

Reproductive Medicine Review, 1993
Micromanipulation technology entered the forum of human conceptionin vitroin the late 1980s. It was erroneously perceived as a new technology – a purely mechanical approach to bypass failures of conceptionin vitro, the aetiology of which were unknown. In fact, it is the modification of technology developed since the beginning of this century, and its ...

Micromanipulation of cryopreserved embryos and cryopreservation of micromanipulated embryos in PGD
Molecular and Cellular Endocrinology, 2000The possibility to employ cryopreservation in Preimplantation Genetic Diagnosis (PGD) should enlarge the opportunities for research and clinical activity. For these purposes, we tried three kinds of approaches on human abnormal embryos: (1) cryopreservation of biopsied embryos; (2) biopsy of thawed embryos; and (3) biopsy of embryos derived from thawed

Calibration of a micromanipulation system
IEEE/RSJ International Conference on Intelligent Robots and System, 2003Calibration is indispensable for automatic micromanipulation. In this paper, using the height difference between different focus planes detected from the microscope and the coordinates of the probe measured from encoders, systematic methods to calibrate the relative position and orientation between the tools and the microscope are developed.

Micromanipulation of sonoluminescing bubbles
Physical Review E, 2004Micromanipulation of sonoluminescing bubbles is achieved by generating a complex sound field consisting of spatially distributed modes of higher harmonics of a basic driving frequency. Bubbles can be manipulated in space and shifted to any desired spot.

Development of micromanipulator and haptic interface for networked micromanipulation
IEEE/ASME Transactions on Mechatronics, 2001Telemicromanipulation systems with haptic feedback, which are connected through a network, are proposed. It is based on scaled bilateral teleoperation systems between different structures. These systems are composed of an original 6 degree of freedom (DOF) parallel link manipulator to carry out micromanipulation and a 6-DOF haptic interface with force ...

Eppendorf Micromanipulator: Setup and Operation of Electronic Micromanipulators
2012Eppendorf AG, Hamburg, Germany, has created many devices and tools that are now considered breakthroughs in the field of laboratory applications. The importance of micromanipulators appeared before assisted reproductive technology (ART) proved its effectiveness. In the 1960s, different groups were experimenting with fertility in animal models.
