Abstract
PURPOSE:To always stably keep the internal pressure of the body cavity constant, by setting the internal pressure of the body cavity constant and comparing set pressure with detected pressure by a suction control means to operate a suction means for a definite time length. CONSTITUTION:Set pressure is compared with the detected pressure due to a pressure detector 16 in a CPU 25b and, when the detected pressure becomes higher than the set pressure, a suction tube 14 communicates with a suction means 15 for a definite time length and the air in the body cavity is sucked through a forceps channel 11 to reduce the pressure in the body cavity. A definite time length during which said sucking (vacuum) operation is performed is stored in the memory 25c of a microcomputer and, at the time of an automatic mode, vacuum operation is performed for 0.3sec when the set pressure is below 10mmHg, for 0.5sec when 10-15mmHg, while for 0.7sec when above 15mmHg.
