摘要：
An endoscopic tissue separator surgical device and method. The device has a multi-lumen shaft having proximal and distal ends, a central lumen for accepting an endoscope, and at least two fluid lumens, with a head coupled to the distal end of the shaft and a handle coupled to the proximal end. The head has an endoscope port and at least two fluid ports whose centers are all disposed along an arcuate line of curvature, while the handle has at least two fluid supply ports. Gas and fluid may be conveyed through the shaft from the handle to the head in the at least two fluid lumens separate from the lumen for accepting an endoscope. At least one lumen of the multi-lumen shaft may house a stainless steel tube with an inside diameter of sufficient size to accept an endoscope.
