Abstract:
A transverse shift screw tail, a transverse adjustable spinal screw, and an implantation method. The screw comprises a screw tail and a screw seat, the screw seat has a rod groove used for placing a connecting rod, which is recessed downwards from the top of the screw seat and radially penetrates the screw seat, a bottom of the rod groove is a curved surface adapted to an outer circumferential surface of the connecting rod, and the rod groove is provided with a locking thread fit with a locking bolt. The screw tail comprises a fixing column capable of being screwed into a vertebral body and a platform located at an end portion of the fixing column, the platform is provided with the installation head used for connecting with the screw seat, and an eccentric distance is provided between a center of the installation head and an axis of the fixing column.

Claim (Index 13):
A method for implanting a transverse adjustable spinal screw into a vertebral body, the transverse adjustable spinal screw being the transverse adjustable spinal screw according to  claim 5 , characterized in that the method comprises the following steps:\n 1) determining a screwing-in point P of each screw on the vertebral body ( 6 ) and screwing the screw tail ( 1 ) of each screw into the vertebral body ( 6 ) from the preset screwing-in point P; 2) setting a placement position of the connecting rod ( 3 ) on the vertebral body ( 6 ) and marking the placement position of the connecting rod ( 3 ) as a reference line L; 3) rotating the platform ( 12 ) to enable the center of the installation head ( 13 ) to approach the reference line L to the utmost extent; 4) installing the screw seat ( 2 ) on the installation head ( 13 ) of each screw tail ( 1 ) and rotating the screw seats ( 2 ) to enable the axis of the rod grooves ( 21 ) of the screw seats ( 2 ) to be located on the same line; 5) inserting the connecting rod ( 3 ) into the rod grooves ( 21 ) to enable all screw seats ( 2 ) to be integrally connected; and 6) installing the locking bolt ( 4 ) at the top of each screw seat ( 2 ), the locking bolt ( 4 ) stretching into the rod groove ( 21 ) and being fit with the locking thread ( 22 ) in the rod groove ( 21 ).
