FIELD: medicine.
SUBSTANCE: functional structure of axial back-and-forth turning of electromagnetic retainer of medical and diagnostic tool in a toroidal surgical robot system comprising a drive with reduction gear for axial rotation, common housing of robot system with linear drives, on extension part of which with possibility of turning there is a sequence of housings of extension elements fore turning by corresponding drive with a reduction gear, last housing, which is made from first part of last housing of extension elements and second part of last housing of extension elements, at end of which there is a drive with a reduction gear, pinion of which is functionally connected with gear with axial rod to turn housings for retaining medical instruments, 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 of 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 drive with reduction gear for axial turning is fixed at beginning of second part of last housing of extension elements, rotor of which is coaxially secured on one half of first part of last housing of extension elements, inside of which orthogonal to rotor of drive with reduction gear for axial rotation there is an axial rod with an axial bore with a thread, where there is a thread of outer part of turning rod, inner part of which with turn gear is located in last but one housing of extension elements, where drive with reduction gear is fixed, pinion of which is functionally connected with turn gear.
EFFECT: invention can be used in various medical procedures.
