DRIVER-SCREW RETENTION MECHANISM

摘要

The present teachings provide an instrument for inserting a fastener. The instrument can comprise a shaft having a distal end defining a tip for driveably engaging a head of a fastener. The instrument can include a filament having a loop proximate the tip. The loop can define an opening for capturing the head of the fastener and retaining the fastener to the shaft. The instrument can also include a tensioning device for applying or releasing tension on the filament to change a size of the opening.
