摘要：
A method for attaching a head to a drive shaft may include winding a wire to create a drive shaft, selecting a head, forming a tapered tip on a distal end of the drive shaft, placing the head on the tapered tip such that a distal end of the tapered tip extends from a distal end of the head, engaging the distal end of the tapered tip and turning down the drive shaft to create a turned down portion, advancing the head proximally over the turned down portion, and disengaging the distal end of the tapered tip wherein the drive shaft frictionally engages the head.
