Abstract
An insufflator for insufflating a body cavity includes a compressed air vessel and a flow control valve for delivering insufflating air to the cavity through a first trocar. A discharge control valve at an outlet port of a second trocar exhausts insufflating air from the cavity. A pressure sensor on the first trocar monitors cavity pressure, and a microcontroller operates the flow control valve for maintaining a predefined working pressure in the cavity. A foot operated switch is operable by a surgeon for opening and closing the discharge control valve. When the pressure in the cavity drops below the predefined working pressure, the flow control valve increases the insufflating air to the cavity, thereby increasing the insufflating air flow through the cavity for removing undesirable gases. The apparatus and insufflator may also be adapted for removing smoke, nitrogen or other undesirable gases during both cauterisation and cryogenic procedures.
