Abstract:
A plate puller device can include a head portion and extension rod portion. The device enables the fastener receiving member to be pulled against a bone surface before a head section of the fastener is advanced within the fastener receiving member into a locked position. The head portion can be positioned between the head section of the fastener and a surface of the fastener receiving member not adjacent to the bone surface. Also, a plate puller device can include a screwdriver, a grasper portion and a grasper sleeve. The grasper portion and grasper sleeve can be threadingly mated wherein rotation of the grasper sleeve forces a head portion of the grasper portion to grip the head section of the fastener to prevent the head section from advancing within the fastener receiving member.
