FIELD: medicine.
SUBSTANCE: functional structure of axial back-and-forth turn of an electromagnetic retainer of medical and diagnostic tool in toroidal surgical robot system, wherein common housing of robotic system has a toroidal shape with inner extension part with spherical cover with possibility of lifting, coaxially to which in its lower part is fixed a tool table with possibility of reciprocal turning and with electromagnetic devices for retention of medical instruments, wherein multiple linear drives, in which extension part is oriented vertically upwards, are arranged regularly in a circle in lower part, common housing and their lower parts are fixed on a common plate or individual plate with possibility of reciprocating turning inside toroidal common housing of robot system, wherein first drive with reduction gear for axial rotation is fixed at beginning of second part of last housing of sliding elements, and its rotor with gear by one or two successive bearings is fixed in longitudinal hole made in first part of last housing of sliding elements, and rotor gear is functionally connected with first gear for axial rotation of second part of last housing of sliding elements, which is fixed inside first part of last housing of sliding elements, inside of which orthogonal to first rotor drive with reduction gear for axial rotation is fixed by axial rod with axial hole with thread, where there is thread of outer part of turning rod, inner part with turning gear is located on one side of second part of last but one housing of sliding elements and is functionally connected with second rotor gear drive with reduction gear, on other side of second part of last housing of sliding elements is fixed a second drive with reduction gear for axial rotation, and its rotor with gear by one or two successive bearings is fixed in longitudinal hole made in first part of last but one housing of sliding elements, and gear of rotor is functionally connected with second gear for axial rotation of second part of last but one housing of sliding elements, which is fixed inside first part of last but one housing of sliding elements.
EFFECT: invention can be used in various medical procedures.
