In a probe adapted to provide an isolated operating room at the distal end of the oesophagus for facilitating the execution, via endoscopy, of a haemostatsis and consisting of a tubular member of flexible material which connects at its distal end two bladders that are inflated to isolate the operating field from the gastric cavity and the proximal portion of the oesophagus, an improvement consisting in that, in order to avoid that the endoscope is squeezed against the walls of the oesophagus when the proximal bladder is inflated, the endoscope probe is passed inside the proximal bladder into a suitable tubular duct which is competely apart from and independent of both said bladder and the main tubular duct. Sealing means are provided in order to avoid that blood and/or the cleaning liquid can rise from the operating room through such tubular duct up to above the proximal bladder. |
