Abstract:
Provided is a spinal implant which includes a compact housing usable in common regardless of a bone screw diameter and is good at assembling properties. A spinal implant includes a screw head holding member, a housing, and an insert. The screw head holding member includes a cylindrical section which is elastically deformable in the radial direction and which includes a support section that supports a screw head from a lower side. The housing accommodates the screw head holding member holding the screw head. The screw head holding member further includes an elastic deformable section which is elastically deformable in the radial direction of the cylindrical section so that an engagement section can engage with the inner circumferential surface of the housing.

Claim (Index 1):
A spinal implant that fixes a rod to a vertebra, the spinal implant comprising:\n a screw head holding member comprising a cylindrical section which is elastically deformable in a radial direction and which has a cylindrical shape and holds a screw head of a bone screw from outside, the bone screw being fixed to the vertebra with a screw body screwed to the vertebra, the screw body comprising an external thread on an outer circumference of the screw body, the cylindrical section comprising a support section that supports the screw head from a lower side where the lower side denotes a side to which the screw body extends from the screw head; a housing which accommodates the screw head holding member holding the screw head and in which an inner circumferential surface of the housing engages with an engagement section in the screw head holding member; and an insert which is disposed on top of the screw head within the housing and which fixes the housing to the screw head by pressing the screw head downward while receiving pressing force by the rod pressed by a set screw screwed to the housing, wherein the screw head holding member further comprises an elastic deformable section which is elastically deformable in a radial direction of the cylindrical section and which allows the engagement section to engage with the inner circumferential surface of the housing.
