History

  • Early Concepts (1970s-1980s): Initial ideas for remote surgery arose from NASAโ€™s telemedicine research, aiming to support astronauts in space.
  • First Prototypes (1985-1990): The PUMA 560 robotic arm performed neurosurgical biopsies, marking the first documented use of robotics in surgery.
  • Development of Dedicated Systems (1990s): The SRI Green Telepresence Surgery system and the Computer Motion AESOP robot introduced voice-controlled camera manipulation.
  • FDA Approval and Commercialization (2000): The da Vinci Surgical System became the first robotic platform approved by the FDA for laparoscopic surgery, revolutionizing minimally invasive procedures.
