MECHANICAL MICROMANIPULATOR (VERSIONS) Russian patent published in 2019 - IPC A61B34/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to a micromanipulator design for high-accuracy instrument positioning for accurate spatial orientation thereof and microsurgical manipulation in the surgical target region. A mechanical micromanipulator for high-accuracy positioning of the instrumentation for accurate spatial orientation and microsurgical manipulation in the area of the surgical target comprises a unit for fixing and moving the instrumentation, which is made in the form of a support, a mechanism for transmitting motion, an installation device. Support contains carriage with slider, on which tooling is directly fixed. Carriage is coupled with movement transmission mechanism made in the form of single unit including mechanism of rotation around horizontal axis, conjugated with support. Rotation mechanism around vertical axis is conjugated with rotation mechanism around horizontal axis and is arranged in housing, and between them connecting plate is installed, fixed on rotation mechanism around horizontal axis, and on housing of rotation mechanism around vertical axis fixed mounting device of micromanipulator, having possibility of interaction with holder of micromanipulator. Rotation mechanism around horizontal axis and rotation mechanism around vertical axis additionally contain retainers. Support, rotation mechanism around horizontal axis and rotation mechanism around vertical axis each have handle, screw and bearings. Rotation mechanism around vertical axis is made with carrier with insert, and connecting plate has possibility of interaction with drive. In compliance with second version, mechanical micromanipulator for precise positioning of instrumentation for accurate spatial orientation thereof and microsurgical manipulation in surgical target area, comprises above unit for fastening and movement of tools, made in form of support, said mechanism for transfer of motion, above-mentioned installation device. Support includes carriage with slide, on which reverse one-side rail is fixed for attachment and movement of tool. In the third embodiment, a mechanical micromanipulator for high-accuracy positioning of the instrumentation for accurate spatial orientation of the instrumentation and microsurgical manipulation in the area of the surgical target comprises the above node for attachment and movement of the instrumentation, made in the form of a support, motion transmission mechanism and mounting device. Support includes carriage with slider, on which one-side rail is fixed for attachment and movement of tool.

EFFECT: use of inventions makes it possible to use various versions of attachment of tools due to structural support solutions, to ensure compactness of micromanipulator due to implementation of movement mechanism in form of single unit, in accurate positioning, including in hard-to-access areas of use, in the presence of a rotation mechanism around the horizontal axis and rotation mechanism around the vertical axis in a single unit and their interaction, in the elimination of play when mounting the retainers on the rotation mechanism around the horizontal axis and the rotation mechanism around the vertical axis.
