For biological experiments requiring manipulations under a microscope, it is necessary to have remote control for the manipulator. Available systems offer the required accuracy at a high cost. Passive micromanipulators are economical but are deficient in performance, the most serious defects being the inability to attenuate operator-induced vibrations ...

Optical micromanipulation has engendered some major studies across all of the natural sciences at the mesoscopic scale. Though over thirty-five years old, the field is finding new applications and has lost none of its dynamic or innovative character: a trapped object presents a system that enables a calibrated minuscule force (piconewtons or less) to ...

Archives of Otolaryngology - Head and Neck Surgery, 1961
The technical equipment of oto-microsurgery has especially during the last 2 decades been developed in many respects. Zeiss' operation-microscope (1953) is a sign of this development; also, knives, chisels, drills, scissors, etc. have been specially constructed for oto-microsurgery. In spite of all improvements the unsuccessful operations that now and

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 ...

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 ...

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.

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 ...

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.
