Osteodisc is a bone mill designed for use in grafting procedures. It can be used to transform autologous bone harvest into suitable particle sizes for use in bone grafting procedures.
The Osteodisc consists of two distinct devices, one re-usable and one disposable. The main unit of the Osteodisc is a hand-held, non-disposable stainless steel instrument that provides assistance in grinding large pieces of bone into small granules and consists of an upper and lower receptacle that is threaded together. The main unit has been designed to fit any sterilizer.
The second device is the graded disposable disc-shaft assembly unit, designed for use solely with the Osteodisc unit to produce the desired bone granulometry.
