Abstract: Operation system with a gas and/or liquid pump, to which is connected at least one flexible-tubing line and which includes at least one control device controlling the flow-through quantity of the gas and/or the liquid in the flexible-tubing line, is proposed. In addition, an operator's control unit with actuating elements is provided, which is joined to the control device by means of a control line and with which the flow-through quantity can be adjusted. Control line (24) and actuating elements (16, 17) form at least two control channels independent of one another and the control device includes a memory, which stores a multiple number of control programs providing application-specific procedures, which can be selected on and off by a specific actuation pattern of actuating elements (16, 17). Prespecified actuation patterns of actuating elements (16, 17) are assigned to the control programs, by means of which the course of the application-specific procedure can be controlled.

Abstract: The invention relates to a gas connection device for insufflation equipment, in particular for mini-invasive surgery as well as laparoscopy and hysteroscopy. The invention includes a connection port 3 for the gas supply, a pressure reducer 4, a safety valve 5, a gas outlet port 7 provided with a solenoid vane 6, and a manometer 8.In order to have an economic assembly of all components of the gas connection device pre-assembled in an insufflation device, it is provided, according to the invention, that the connection port 3, the pressure reducer 4, the safety valve 5, the solenoid valve 6, with the gas outlet port 7, and the manometer 8 are connected to a common metal main body 1, and are connected to a common metal main body 1, and are connected with main body 1.
