DEVICE: Medline (10888277334472)

A metal shaft intended to be mounted into an appropriate surgical power tool (e.g., a pneumatic reamer or drilling system handpiece with appropriate torque capacity) and rotated to bore into hard/tough tissues (e.g., bone, cartilage) in order to clear a channel of the same diameter as the shaft, typically for the insertion of a prosthetic device or other orthopaedic implant. It has a hollow centre so it can be fed over a drill guiding pin, and may be flexible; devices to assist the procedure (e.g., drill guiding pin, manual driver) may be included. This is a single-use device.

A shaft of metal with an obtuse, V-shaped cutting edge designed to be rotated to bore into bone to create a hole of the same dimension as the diameter of the shaft. This device, commonly called a "twist drill", has a cylindrical design with a double-edged cutting head that is formed from two spiralled flutes that extend the length of the insertion part of the drill. At the proximal end, it is mounted into a surgical power tool or a surgical hand drill/brace. This is a single-use device.
