The TCAT computer-assisted tool uses the pre-operative plan created by the surgeon in the 3D Planning Workstation for preparation of the bone cavity and joint surface.
The TCAT is staged in the OR, followed by patient positioning, surgical incision and fixation. Using the bone registration process, the surgeon uses a digitizer to collect points and locate the exact position of the patient’s anatomy for precise surgical implementation.
Under direct control of the surgeon and using controlled, gentle pressure, TCAT prepares the bone with sub-millimeter dimensional accuracy as specified by the plan. The specialized bone cutters and other hardware have been developed for accurately preparing the bone to achieve optimal fit of the implant.
If bone motion occurs, a Bone Motion Monitor stops the surgery. The registration system then allows the surgeon to quickly recover bone position and resume the surgery.
The TCAT cuts cavities and planes the femoral and tibia surfaces for knee implants.
