Pedicle nail and spine board form certain angle, pass through locking nut.
The technical solution adopted for the present invention to solve the technical problems is：One kind can be with rod convolution spine board, including ridge
Post plate, the spine board side are provided with long slot bore, and the spine board opposite side is provided with the oblique U-type groove of opening, described tiltedly in U-type groove
Side is provided with screwed hole, is provided with pedicle nail in the long slot bore, the pedicle nail includes thread head, the ball of middle and upper part at top
Head and the body of rod of lower end, the pedicle nail are fixed by locking nut and are locked in spine board long slot bore.
Further, including long spine board is provided with horizontal long slot bore or the long slot bore of longitudinal direction.
Further, including at the top of long slot bore it is spherical groove, long slot bore bottom is spherical elongated slot.
Further, including the spheroid of pedicle nail middle and upper part is outer-hexagonal shape.
Further, including bulb spheroid outer-hexagonal by being processed at fillet.
Further, including the axis angulation angle of the axis of long slot bore and pedicle nail is α °.
The invention has the advantages that one kind of the present invention can be provided with the oblique U of opening with rod convolution spine board, spine board
Type groove, while the platy structure provided with ball and matched pedicle nail and locking nut composition, pedicle nail bottom
The body of rod inserts spine board by long slot bore, is used cooperatively with spine board screw-rod so that pedicle nail and spine board form one
Determine angle, by locking nut, more piece backbone can be fixed, so as to applied to more complicated situations.
