CANNULATED FLEXIBLE DRIVE SHAFT

摘要

A flexible cannulated drive shaft (1) having a plurality of interlocking sections (6) having multi-angled dovetails cut into the drive shaft. Each dovetail design is made up of substantially triangular-shaped pins (7) and substantially triangular-shaped sockets (8) that alternate around the circumference of each interlocking section. The pins of one interlocking section moveably engage the sockets of a second interlocking section and vice versa. Furthermore, the substantially triangular-shaped pins and substantially triangular-shaped sockets stay locked together whether the drive shaft is being rotated clockwise or counterclockwise. Angled surfaces (21, 22) add greater stability to the drive shaft and prevent the interlocking sections from coming apart.
