The ROBODOC Surgical System includes two leading-edge components: ORTHODOC®, a 3-dimensional workstation for preoperative surgical planning, and the ROBODOC® Surgical Assistant, a computer-controlled surgical robot used for hip replacement surgeries. In traditional manual techniques, the removal of bone is done using handheld surgical instruments. However, even the most skilled surgeons lack a degree of precision due to the limitations of the surgical instruments. With the ROBODOC Surgical System, the combination of the preoperative planning with the execution of the ROBODOC robot assisted technique can lead to a more precise removal of the bone and implant placement.
