Traction Cybernetic Avatar System for Colon ESD.

Colorectal Endoscopic Submucosal Dissection (ESD) is a highly specialized and technically complex procedure designed for the en bloc resection of colonic tumors. The intricate and confined anatomical structure of the colon imposes considerable challenges during ESD. Implementing an effective traction mechanism can streamline the procedure, shorten operative duration, and reduce the incidence of complications. This study introduces a novel ESD traction system integrating a scaffold and a lesion traction mechanism, designed to provide controlled and adequate tension, thereby facilitating the progressive distal descent of the lesion as submucosal dissection advances. Additionally, a strain gauge-based minute force sensor was developed to enhance precision and safety, effectively mitigating the risks and complexities associated with achieving complete lesion resection.Clinical Relevance- This novel system improves ESD by providing stable and adjustable traction, significantly improving submucosal visualization, mitigating procedural complexity, and minimizing risks like bleeding and perforation.
