Endoluminal minirobots for transgastric peritoneoscopy.

The performance of surgeries through small incisions or natural orifices minimizes the invasiveness to the patient as compared to open procedures. However, the constraints on visual feedback and dexterity limit the scope of these procedures. Recent robotic technologies attempt to mitigate these constraints for flexible endoscopy and laparoscopy. Much of the current work in flexible endoscopy is in the development of a fully autonomous endoscope capable of providing the surgeon with better control. Advancements in laparoscopic technologies have demonstrated abilities to improve visualization and dexterity through telerobotics and in vivo robotics. The application of new robotic technologies in flexible endoscopy and laparoscopy to natural orifice surgery promises to further benefit the patient by eliminating abdominal incisions, scarring, and the pain associated with these incisions. The safety and feasibility of such robotic technology has been successfully demonstrated for natural orifice transluminal endoscopic surgery (NOTES) in animal models.
