1A2-K04 Development of forceps for ESD surgery : Development of affected area retention tool

Abstract

Endoscopic Submucosal Dissection (ESD) is type of a minimally invasive surgery. In this surgery, it is difficult to ensure visual field of edges of the excised tissue when doctors perform to detach submucosa. We have been developing a surgical tool that can hold up diseased tissue with a vacuum contact parts which doesn't make mucosal tissue damaged and enable to inflect automatically. In this paper, we had experimented the retention force of surgical tool developed here for gastric mucosa tissue of pig. Experimental results indicated that this tool was able to produce the retention force by using a Bellows type vacuum pad, and the retention force was independent of the plicae size and prevent some damages to the mucosal tissue.
