The invention relates to precision instrument engineering and can be used in order to create microdisplacements in micron and submicron ranges for cellular microtechnologies (by engineering, gene engineering, reproductive diology and medicine, neurobiology, microphysiology, cytology, etc.), micromechanics and for the electronics and other industries. Said invention is characterized by reduced associated mechanical vibrations of a micromanipulator, high resolution (accuracy), a decreased number of single displacements, the extended speed adjustment range and functional capabilities of the micromanipulator. The inventive micromanipulator comprises a small movable table attached to a drive which is connected to a control unit and embodied in the form of a shaft provided with a rotor which is linked with annular piezoelements by means of pushers. One piezoelement is arranged on the shaft and the second piezoelement on a body. The control unit is embodied in the form of the following serially connected parts: a high-frequency pulse generator for piezoelement excitation, a controlled key, an amplifier connected to the corresponding piezoelement, a unit for generating the frequency of a pulse packet for piezoelement excitation and a unit for forming a burst time connected to the control input of the key.
