FIELD: electricity.
SUBSTANCE: invention suggests assembly of hand-operated module and intervening tool, magnetic resonance system and method for control of the assembly. The assembly contains the first transmission line (102) connected to winding (106) of the device passing almost up to the intervening tool (104). Axial position of the winding (106) is set selectively by means of axial sliding of the device in regard to the first winding (108) of the intervening tool (110). The assembly contains a hand-operated module consisting of an insulation barrel (70) supporting a section of the intervening tool with the second transmission line (50, 112) in an internal opening (62) at a certain gap from it; and winding (64, 118) of the hand-operated module placed along the opening, at that winding of the hand-operated module interacts with the second transmission line in order to form an electromagnetic coupling with the transmission line. The second transmission line (112) connected to the second winding (114) of the intervening tool passes along the intervening tool (110); axial position of the second winding (114) of the intervening tool is set selectively by means of axial sliding of the intervening tool in regard to a coil (118) of the hand-operated module (32).
EFFECT: improving safety of a patient during use of the assembly.
