A method of placing screws into bone or tissue structure during a medical procedure uses a power driven screw driver, a fastener carrier 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. Activating a trigger mechanism causes the tip of the screw driver to extend and interlock with the head of the fastener temporarily held in the band, removing the fastener from the band, rotating the driver tip and fastener for driving the fastener into a tissue or bone structure, and releasing the trigger following positioning of the fastener in the bone or tissue disconnects the screw driver tip from the fastener head, retracts the screw driver tip from the band and causes the fastener carrier system to advance forward to position a subsequent fastener in a location for grasping by the screw driver tip.
