Abstract
A bone attachment assembly may include an attachment head, a set screw configured to attach to the attachment head, and a rod surface with a first raised portion and a second raised portion that define a lowered portion positioned between the first raised portion and the second raised portion. The first raised portion, the second raised portion, and the set screw may be configured to directly contact a rod in order to retain the rod within the attachment head.
Claims15
A bone attachment assembly comprising:
- an attachment head having an opening formed through one side, wherein the opening is configured to allow insertion of a rod through into the attachment head;
- a set screw configured to attach to the attachment head;
- and
- a rod carrier pivotably coupled to the attachment head and having a rod surface with a first raised portion and a second raised portion that define a lowered portion positioned between the first raised portion and the second raised portion, wherein the rod carrier is pivotable about a lateral axis perpendicular to an axis of the attachment head,
- wherein the first raised portion, the second raised portion, and the set screw are configured to directly contact a rod in order to retain the rod within the attachment head,
- wherein a threaded screw shaft is attached to a base region of the attachment head, wherein, when the rod is positioned on a portion of the rod surface and a longitudinal axis of the rod is substantially perpendicular to the longitudinal axis of the threaded screw shaft, the first raised portion, the second raised portion, and a pointed tip of the set screw define three points of contact of the rod within the attachment head, wherein the rod is held within the attachment head by only the three points of contact.
