Endoscopic submucosal dissection-assistance robot: a miniature surgical manipulator for endoscopic submucosal dissection

One-handed operation and gravity-induced blind dissection are technical difficulties in endoscopic submucosal dissection (ESD) procedures [1]. In order to reduce the difficulty of the procedure and minimize the risk of perforation and bleeding, we have developed a microsurgical manipulator, the ESD-assistance robot, which provides a "second hand" with auxiliary traction, clamping, and fixation functions during procedures.
