摘要：
The invention relates to the field of instruments for surgery. Surgical oscillatory saw comprises a base cutting blade head with the housing, tool holder and a mounting slot for the blade adjusting unit spatial position of the cutting blades in different planes with in-cage assembly locking mechanism in the form of an eccentric which converts the rotational motion of the motor rotor mounted in the housing with the handle in an oscillating movement of the cutting blade. Node fixing position bearing the cutting head blade is provided with a non-closed ring having elastic properties, the sleeve formed with a radial groove and two diametrically located openings, each of which is mounted movably up and down the ball and ring, along the outer cylindrical surface of which are made grooves . The sleeve is fixedly mounted in a holder fixing assembly ring with slots is installed in the sleeve and is fixedly connected with the housing carrying the cutting head the blade, and the open ring is set in a radial groove of the sleeve with the possibility of pressing the balls in the radial direction corresponding to the grooves of the ring. The holder is provided with a blade mounted movably on the vertical axis of the finger with the divisions of different diameter and keyway. Finger in the holder body is provided with a cylindrical cavity departments, whose diameter corresponds to the diameter of the respective finger sections. The holder blade is also provided with a sleeve movably mounted directly below the tool holder, a package of disk springs, a washer and a compression spring mounted at the sleeve from top to bottom, a plurality of which is intended for fixing the blade in the bearing seat. Provided screw installed in the groove finger to restrict its movement. Bearing seat for the blade is designed as a flatbed ribs r-shaped, laterally mounted platform. The utility model is structurally more simple, it lacks the details are very complex shapes. Reduced possibility of leakag
