Cannulated fastener system

摘要

A cannulated fastener system is provided for orthopedic applications that include attaching bone plates to bone. The bone fastener has a cannulation with an inner shape. One or more screwdrivers is provided with a shaft having a shape that matches the cannulation of the fastener to rotationally fix the fastener to the screwdriver. In addition, the screwdrivers have a cutting blade that begins the drilling of a hole for the bone fastener. The screwdrivers may either be for use with a single fastener or have multiple fasteners loaded within a retaining sleeve for automatic or controlled dispensing.
