Considering Endoscopic Design: A Snakebot Prototype

Endoscope design is at the intersection of many disciplines, including robot design, computer science, material science, and medical devices. When considering design features, it is important to ensure that the device safely navigates the patient's body and, once in position, performs the task required by the surgeon. Whether surgical access is achieved through existing orifices or by small incisions, the goal is to provide the surgeon with a stable platform within the patient from which to cut, suture, and grasp, while transmitting a clear image. The device described in this article can generate force at the tip of the snakebot in any direction without pressing against interstitial tissue to redirect the applied force.
