Endoscopic submucosal dissection of early gastric angle cancer by using a simplified robot-assisted device for traction

Abstract

Endoscopic submucosal dissection (ESD) is the standard technique for resection of gastric superficial tumors. However, in difficult locations of the stomach, a vertical approach toward the muscular layer is always unavoidable and results in a higher risk of damage [1]. To help address these issues, we designed a flexible auxiliary single-arm transluminal endoscopic robot (FASTER). The operator can utilize its external control system to precisely manipulate the grasping forceps, exerting a controlled pulling force in multiple directions away from the gastric wall ([Fig. 1]) [2].
