ABSTRACT:
An endoscope system is provided in which air is pumped into a first channel into the endoscope in order to pressurize the body cavity and a forceps channel is connected to a suction pump in order to drain the body cavity of fluid, air and debris. Either a second suction pump or a second supply of air is connected to the forceps channel along with a pressure detector for controlling suction. Further, a suction tube is also provided which is connected to, and which communicates with, a forceps channel in which a medical tool is adapted to be inserted, and a suction device is, in turn, connected to and communicates with the suction tube. Pressure within the suction tube is detected by a pressure detecting device, and the detected pressure is indicated on the display. A suction control device is provided which controls operation of the suction device by operating based upon an output signal from a pressure setting device for setting a maximum value for the body cavity pressure and an output signal from the pressure detecting device. A laser knife is also provided which includes a protective pipe surrounding a fiber optic laser transmitting member for forming a first gap and a tube surrounding the protective pipe to form a second gap. Gas is passed through the first gap to cleanse the emitting end of the laser transmission member. A pressure detecting device is coupled to the second gap in order to monitor pressure within the stomach, and a suction device which is responsive to the pressure detecting device is also connected to the second gap in order to control gas pressure within the stomach.
