Sled dials in hinge member the shoulder hole B and screw hole that are provided with and pass for hold-down bars, and it is arranged on hold-down bars by the shoulder hole B on it;
Pedicle of vertebral arch sled group screw rod is arranged on sled by the sled hole D dialled on hinge member and dials on hinge member, and vertical with tranverse connecting rod with hold-down bars;
The bottom of pedicle of vertebral arch lock nut is cancellous threads section, and middle part is locking screw thread section, and top is outer-hexagonal;
Described junction button, locking hinge parts and sled are dialled on hinge member and respectively screw are housed.
The further technical scheme of the present invention is: locking hinge parts are positioned at the outside of two hold-down bars, and sled dials the inner side that hinge member is positioned at two hold-down bars.
The present invention further technical scheme is: the part in the C inwall of described hole is provided with female thread, and the part in locking screw thread section is plane.
The present invention further technical scheme is: the longitudinal section shape of locking hinge parts is the pentagon that rectangle cuts away an angle below, and namely the lower end of locking hinge parts is the wedge angle on a band inclined-plane; The longitudinal section shape that sled dials hinge member is the pentagon that rectangle cuts away an angle below, and namely sled dials the wedge angle that the lower end of hinge member is a band inclined-plane.
The present invention as above designs owing to adopting, the wound overcoming present conventional therapy Therapeutic Method existence is long, hemorrhage many, easy infection, affect the weak points such as the external beauty treatment of patient, compared with prior art, have applied widely, easy and simple to handle, in use Stability Analysis of Structures is reliable, has the advantages such as stronger anti-rotation effect.
