Development of a novel deployable arm for natural orifice transluminal endoscopic surgery(NOTES)

xlomafota13 shared this article with you from Inoreader Development of a novel deployable arm for natural orifice transluminal endoscopic surgery(NOTES) Via The International Journal of Medical Robotics and Computer Assisted Surgery Abstract: Background NOTES is aided by the instrument channel of an endoscope. Limited by the diameter of the endoscope, the construction of the operation triangle is affected. This paper presents a deployable arm that can increase the distance between the arms. Methods The manipulation arm is composed of a continuum arm and a deployable arm. The deployable arm can be locked by a stay cable and a mechanical structure. The angle between the end‐effectors and the common workspace of the two manipulation arms are comprehensively analyzed. Through experiments, the design parameters are validated and justified. Results The experiment shows that the deployment arm can maintain the deformation within 3.5 mm under a 300 g load, and the angle between the two end‐effectors can be maintained within the range of [88o ,110o]. Conclusions The novel deployment arms enlarge the angle between the end effectors, which significantly improves the flexibility of the arms. This article is protected by copyright.
