Abstract

A hydraulic transformable endoscopic hood for endoscopic surgery has been developed. The device can be attached at the tip of an endoscope to assist physicians operating endoscopic submucosal dissection (ESD), which is an operation for removing lesions in digestive organs. This device can provide large field of view and ease the process of inserting the tip of an endoscope into incisions as well. We developed a transformable hood using hydraulic actuators. The hydraulic actuator consists of biocompatible Parylene membrane and stainless steel coil. The tip of the hood is divided into three parts. The tip parts open when pressure is applied to the hood, thus expanding the tip radius of the hood. By changing the applied pressure, the tip radius ranged from 4.5 mm to 11.5 mm. When the tip diameter was fixed to 16 mm, the maximum force generated by the hood was 123 mN.
