Jones Screw Instrument Kit

Surgical countersink, single-use. A rotary surgical instrument designed to enlarge the diameter of the proximal portion of a hole drilled in bone. It is a shaft of metal with a cutting head, available in various configurations, that is rotated at low speeds typically by a drilling system. The device is typically used to recess the head of a screw/bolt within bone (enable it to lie flush with or below the bone surface) or to help accommodate the implantation of a device in bone. This is a single-use device intended to be sterilized prior to use.
