Abstract
We have explored the feasibility of performing endo-robotic neck surgery in porcine models applying the techniques of endoscopic neck surgery. We performed thymus gland resections, submandibular resections, thyroidectomies and selective neck dissections using the da Vinci surgical system (Intuitive Surgical Inc.).
We observed some distinct advantages associated with the use of the surgical robot. The electronic control system was capable of filtering out hand tremors by virtue of motion scaling, and the proportional movement of the robotic device allowed the instruments to follow directly the movement of the surgeon's hand. The articulating Endo Wrist technology permitted a large range of motion and rotation that tracks the natural range of articulation of the human wrist. Moreover, endo-robotic neck surgery proved to be a safe and efficient in experimental animal models. The innovations of three-dimensional imaging, endo-wrist articulation, and motion scaling are substantial advantages that increase surgical precision and dexterity and decrease the impact of tremor. Further investigation in cadavers, and later, clinical trials will be necessary to determine whether these advantages can be achieved in clinical practice.
