FIELD: medicine.
SUBSTANCE: group of inventions relates to a method for positioning a manipulating arm in a coordinate system (X, Y, Z) of a robotic surgery device. Patient's target zone coordinates (xz, yz, zz) are determined. To position the manipulated arm, the instrumentation unit is connected to the manipulated arm interface unit. Instrumental unit comprises a surgical instrument having an instrument shank with a longitudinal axis. When connecting the tool unit with the interface unit, an intermediate vector (V) between the longitudinal axis and the given coordinates (xz, yz, zz) of the target zone perpendicular to the longitudinal axis is determined using the control unit. First optical and/or acoustic signal is output by the dispensing unit when the value of the determined intermediate vector (V) has a first preset value or is located below it.
EFFECT: simplified orientation of surgical instruments relative to intended target zone.
