FIELD: medicine; medical engineering. ^ SUBSTANCE: device has two rings joined to each other with three rods by means of detachable connection. Strip, having holes, is fixed on one of the rings for placing in them removable guiding bushing receiving drill. Method involves detecting hole for applying blocking screw to an intramedullary rod, drilling and superimposing over extremity in the assumed blockage causing the rings to be arranged on external and internal extremity side and the removable guiding bushing is placed on the side the opening is formed. Drilling point is determined by moving device in carrying out X-ray control in frame-by-frame mode of optoelectronic transducer operation. A guiding bushing position is determined that bushing opening projects over intramedullary rod hole. The rings are rigidly fixed in this position on the extremity. ^ EFFECT: enhanced effectiveness in reducing X-ray radiation dose absorbed by physician and patient. ^ 6 cl, 1 dwg |
