The hole D that pedicle of vertebral arch sled group screw rod is dialled on hinge member by sled is arranged on sled group 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 screw are housed respectively.
The further technical scheme of this utility model is: locking hinge parts are positioned at the outside of two hold-down bars, and sled group hinge member is positioned at the inner side of two hold-down bars.
This utility model 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.
This utility model further technical scheme is: the longitudinal section of locking hinge parts is shaped as rectangle and cuts away the pentagon at an angle below, and the lower end of locking hinge parts is a wedge angle with inclined-plane; The longitudinal section of sled group hinge member is shaped as rectangle and cuts away the pentagon at an angle below, and the lower end of sled group hinge member is a wedge angle with inclined-plane.
This utility model is owing to adopting as above design, the wound that has overcome present conventional therapy Therapeutic Method existence is long, hemorrhage many, easily infect, affect the weak points such as patient's external beauty treatment, 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-rotate effect.
