A novel flexible hyper-redundant surgical robot: prototype evaluation using a single incision flexible access pelvic application as a clinical exemplar

Introduction The flexible endoscope is increasingly being considered as a surgical tool to enable innovative natural orifice or flexible access techniques. These experiences have exposed unique advantages but also significant challenges. Major current technical drawbacks in this setting relate to uncontrolled flexibility, inaccurate sustained target localization, unreliable navigation and overall platform instability. In striving to address existing technical limitations, this paper introduces a novel flexible hyper-redundant surgical robot and evaluates its clinical potential using a focused clinical application.
