Since Intuitive Surgical's da Vinci system earned the FDA nod in 2000, the company has enjoyed a sizable head start in the minimally invasive robotic surgery field. Competition has been brewing for years, from players large and small, but 2018 could be the year the market finally sees a shake-up. North Carolina's TransEnterix scored an FDA nod for its Senhance system in October, triggering a 75% bump in its stock price. The device, a rare new entrant to the robotic abdominal surgery market, is designed to make it easier to perform laparoscopic surgery. It is cleared for colorectal and gynecological surgery and features haptic feedback, so the surgeon can "feel" the tissue that the robotic arm is touching.
