摘要:
FIELD: medicine.SUBSTANCE: invention refers to medicine, namely to a method of controlling movement of a camera attached to a manipulator of a robot-surgical complex. Robot-surgical complex comprises two controllers, a manipulator with a camera for observing an operative field and an automatic control system. Each of the controllers is configured to digitize the movements of the hands of the surgeon and provides transmission of motion vectors on three translational and three rotational degrees of freedom, representing difference between coordinates of controller of control in initial position and coordinates of controller of control at change of position of surgeon's hand. Manipulator provides movement of camera in three translational degrees of freedom. Automatic control system is connected to both controllers and manipulator. Method is characterized by following steps: transmission of motion vectors data on three translational and three rotational degrees of freedom of right and left controllers to automatic control system with constant frequency; performing controllers switching to camera control mode; control of manipulator movement with camera fixed on it. Controllers are switched to the camera control mode by pressing the control pedal. Signal from the control pedal is transmitted to the automatic control system and controllers to lock the rotational degrees of freedom in the latter vector. After the rotary degrees of freedom of the control controller are locked, the vector of rotational coordinates in the automatic control system is reset. Control of manipulator movement is carried out by simultaneous movement of controllers and subsequent execution of following stages: storing the obtained motion vectors of the controllers in the automatic control system; a step of processing and combining the motion vectors of the right and left controllers to find the total movement; a scaling step of the displacement vector obtained at a previous step; a motion compensati
