Abstract
A fastener placement system for placement of screws into bone structure during a medical procedure comprises a power driven screw driver, a fastener carrier system with a series of fasteners temporarily attached thereto and an elongated band structure carried by the fastener carrier system for positioning and advancing the individual fasteners of the series of medical fasteners in a controlled manner to a position to receive a driving tip on the powered screw driver. The head of the fastener and the tip of the screw driver have complementary structures which allow the screw head to be simultaneously grasped by the driver tip and the fastener to be driven in a rotary manner for placement into the bone structure.
