The stomach is a muscular sac that is important for absorbing food and preparing food for further digestion.
Robotic surgery involves using robots for surgery. These robots do not always operate independently though some robots can perform surgical tasks autonomously; however, they do enable surgeons to conduct operations at a smaller scale as compared to conventional surgery and also get closer to the surgical site overcoming the limitations imposed by human vision. Surgical robots also afford greater precision compared to the human hand that is susceptible to muscle fatigue. The limitations of surgical robots include a high cost of equipment to purchase and maintain. Medical staff requires special training which is an added cost as well. Robots have been used for cardiac surgery, neurosurgery, gastrointestinal surgery, gynecology, etc. The da Vinci surgical system and the ZEUS Robotic Surgical System are two systems that were used clinically in the US. The merger of Intuitive Surgical and Computer Motion resulted in the da Vinci becoming the more popular system.
