Robotic surgical systems, such as the da Vinci Surgical System, utilize specialized instruments designed to mimic the natural dexterity of the human wrist and hand.

These instruments are controlled by a surgeon operating from a remote console. By manipulating "master controllers," the surgeon directs the movements of the robotic arms. The system employs computer processing to link the surgeon's hand movements to the instruments, allowing for precise, scaled motions that eliminate unwanted tremors. This "wristed" motion is specifically engineered to provide surgeons with the necessary dexterity to perform complex tasks within the confined spaces of the body during minimally invasive surgery.1
