초록 ▼

An insufflation system which provides continuous insufflation at a pre-set, limited low insufflation gas pressure and a high insufflation gas flow, thereby avoiding the necessity of measuring the intra-abdominal pressure while insuring that a determined pre-adjustable maximum insufflation gas pressure cannot be exceeded. The system comprises a gas delivery line having an inlet end coupled to a source of insufflation gas and an outlet end for connecting to the gas inlet of a surgical laser-equipped endoscope. A pressure adjustment device is connected into the gas delivery line for establishing a maximum insufflation gas flow pressure in the gas delivery line, and a gas exhaust tube that can be introduced into the body cavity provides for exhausting of insufflation gas delivered to the body cavity solely by the gas delivery line via the endoscope.
