Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
The fixing device for head surgery for neurosurgery shown in fig. 1 to 3 comprises a bottom plate 1, a clamp, a horizontal rod 2, an inclined rod 3 and an adjusting device.
The bottom plate 1 is horizontally arranged, and the clamp comprises two arc-shaped side clamping plates 4 and two arc-shaped top clamping plates 5; the clamps are arranged in an annular array, and the top clamping plates 5 are arranged above the side clamping plates 4 at intervals. In order to improve comfort, the inner side of the clamp is provided with a foam-rubber cushion 6. A headrest 7 is arranged at the upper end of the bottom plate 1 and below the clamp.
The adjusting device comprises a fixed block 8 arranged at the upper end of the bottom plate 1, a sliding block 9 arranged at the upper end of the fixed block 8, a horizontal screw rod 10 matched with the sliding block 9, a coupler 11 and a rotating wheel 12 respectively arranged at two ends of the screw rod 10, and a first locking piece 14 and a second locking piece 15 matched with the sliding block 9; the upper end of the fixed block 8 is provided with a sliding chute 13 matched with the lower end of the sliding block 9; the sliding groove 13 is arranged in parallel to the screw rod 10, and the lower end of the sliding block 9 is provided with a protruding strip matched with the sliding groove 13. A horizontal threaded hole matched with the screw rod 10 is formed in the sliding block 9, the sliding block 9 is pushed along the direction of the sliding groove 13, and the screw rod 10 does not move due to the matching of the screw rod 10 and the threaded hole; when the screw rod 10 is rotated by the rotating wheel 12 after the slider 9 is fixed, the screw rod 10 moves along the length direction thereof.
