Abstract
Endoscopic Submucosal Dissection (BSD) is a type of minimally invasive surgery. In this surgery, it is difficult to ensure the visibility of edges of the excised tissue when a surgeon performs the detachment of the submucosa. We have been developing a surgical tool that can uplift the diseased tissue using vacuum contact parts, which don't damage the mucosal tissue, and enables to inflect automatically. In this paper, we had conducted experiments on the retention force of the surgical tool developed here for the gastric mucosa tissue of a pig. Experimental results indicated that this tool is able to produce the desired retention force using a polyester type vacuum pad, a well-known material for blood vessel prosthesis, and the retention force can be obtained using the pad also on an inclined surface. The vacuum pad has been fitted on an endoscope.
