Fortios Bone Mill

The Fortios Bone Mill is a safe and efficient solution for the production of cortico-cancellous bone chips. By combining the Spierings milling technology with a drive unit, we created a motorized bone mill that is easy to use and easy to clean. The Fortios Bone Mill is the perfect milling tool for tissue bank use. Some of its main features are:

  • Bone grafts with intact trabecular structure
  • Easy to use
  • Easy to clean
  • High quality construction
  • Flexibility
Additional information

Bone grafts with intact trabecular structure

To achieve high strength in bone reconstructions the trabecular structure of the graft bone must remain intact. Spierings Tissue Processing has applied its patented milling technology to the Fortios Bone Mill for optimal milling of cortico-cancellous bone. The teeth of the milling drums are spirally positioned and razor sharp, breaking off pieces of bone and leaving the trabecular structure intact.

Easy to use

The Fortios Bone Mill is intuitive to use as it only comprises a couple of parts: Drive Unit, Milling House, Push Block and Milling Drums. All the parts are made of medical grade stainless steel and are extremely durable.

Easy to clean

All parts that come in direct contact with bone can be detached from the Drive Unit and autoclaved to ensure optimal processing conditions.

High quality construction

The Fortios Bone Mill is unique because of its superior design and sturdy construction. The Fortios Bone Mill is made of stainless steel, making it an extremely solid device. The milling drums are made of a special hardened stainless steel alloy. Even in case of frequent use they do not show signs of wear. This combination guarantees a high quality graft without metal contamination.
