Future of Flexible Robotic Endoscopy Systems
This work tackles the problem of invasive and complex endoscopic surgeries for gastroenterologists and patients, representing an incremental advancement in robotic-assisted medical technology.
The paper addresses the challenge of reducing trauma and improving outcomes in gastrointestinal endoscopy by using robotic systems with tendon sheath mechanisms and ergonomic controls, resulting in significantly reduced learning curves for difficult procedures and improved surgical outcomes from clinical trials.
Robotics enables a variety of unconventional actuation strategies to be used for endoscopes, resulting in reduced trauma to the GI tract. For transmission of force to distally mounted endoscopic instruments, robotically actuated tendon sheath mechanisms are the current state of the art. Robotics in surgical endoscopy enables an ergonomic mapping of the surgeon movements to remotely controlled slave arms, facilitating tissue manipulation. The learning curve for difficult procedures such as endoscopic submucosal dissection and full-thickness resection can be significantly reduced. Improved surgical outcomes are also observed from clinical and pre-clinical trials. The technology behind master-slave surgical robotics will continue to mature, with the addition of position and force sensors enabling better control and tactile feedback. More robotic assisted GI luminal and NOTES surgeries are expected to be conducted in future, and gastroenterologists will have a key collaborative role to play.
