Tunnel dilators are used to safely expand the size of tibial or femoral tunnels during cruciate reconstruction surgery. They offer a minimally invasive approach to tunnel enlargement, compressing cancellous bone during the process. Their tapered ends allow for easy insertion and removal from the tunnel, while full radiused depth marks in 5mm increments provide accurate guidance for controlling the size of the tunnel. Ergonomic design of T-handle provides comfort and control during use. The dilators are available in cannulated and non-cannulated versions with different diameter ranging from 7mm to 10mm.
