Abstract: For water-jet surgery pump devices are known by means of which a sterile fluid is transported through a reservoir to the surgical instrument by means of piston pumps or similar volumetrically transporting pumps. In accordance with the present invention it is proposed either to construct drive means for the pumps in such a way that their suction cycle is shorter than the output cycle, or to provide a pump with at least three pump chambers and to construct the drive means in such a way that the suction and output cycles of the pump chambers overlap one another.

Abstract: A known arrangement for controlling electromedical appliances or groups thereof employs foot-actuated switches or push-button switches, which are separately connected to each appliance. When it is necessary to control a large number of appliances or appliance groups, a large number of push-buttons or pedal switches is also required, the connections of which cause disturbances in the operating room. In the present invention the switching means or pedal switches are provided with connecting means by way of which the switching means can be connected to one another. Allocation means are provided in order to allocate to the control signals particular controlling functions with reference to the appliances or appliance groups. Information-transfer means transmit control signals from the switching means or pedal switches to the appliances or appliance groups.

Abstract: The invention relates to an apparatus for argon-plasma coagulation in which working gas is supplied to a tissue that is to be treated by passage through gas-supply devices (20) in a supply-flow direction, and the working gas flows out of a distal end of the gas-supply devices. This apparatus for argon-plasma coagulation is further developed with the aim of preventing contamination of the gas-supply devices by working gas, bodily gases and/or bodily liquids. For this purpose at least one obstructor (30) is provided, which is or can be connected to the gas-supply devices and serves to obstruct a flow of gas and/or liquid into the gas-supply devices, against a supply-flow direction.

Abstract: In previously known neutral electrodes which are used in HF surgery, at least some portions comprise electrically conductive, stretchable, and flexible areas made of textile material, these areas being brought into contact with a body section of a patient. According to the invention, such an area is embodied as a stocking, tube, or similar anatomically shaped thromboembolism-preventing envelope, whereby secure contact of the neutral electrode is ensured without requiring any additional device.

Abstract: The invention relates to a connecting device for an electrosurgical instrument, which comprises at least one gas supply line and one power supply line. Said connecting device comprises a housing into which passes the gas supply line including the power supply line disposed therein. The connecting device is also provided with a branching device that is located in the housing, and by way of which the power supply line is diverted out of the gas supply line in order to form a gas-connection end piece and a power-connection end piece, and with a plug fixed to the housing in order to make connection to a socket in an appliance or to connecting leads running to the appliance. The gas-connection end piece and the power-connection end piece are coupled to the plug and a filter is disposed within the housing in the gas-connection end piece.

Abstract: The data processing system has an online transactional processing (OLTP) system for receiving of reporting data from work centers of a production line. The production line is logically divided into shop areas. At the exits of each shop area where an intermediate product is completed one reporting point serves as exit point in order to report the completion of an intermediate production step. This data is stored in the OLTP system and retrieved at a later point of time in order to generate a table containing aggregated intermediate product quantities per shop area. This table is transferred to a financial data server for calculation of the value of work in progress.

Abstract: Data processing methods and systems are disclosed for use in industrial control. The methods and systems may include receiving control data from automation components of an industrial control system by a first computer system, the first computer system being coupled to the automation components by means of a first network, storing at least some of the control data in a first database by the first computer system, performing a database query of the first database for determination of a subset of the control data, aggregating the control data of the subset, and transmitting the aggregated control data to a second computer system over a second network.

Abstract: A foot switch for use in the control of medical apparatus comprises a pedal that is connected to and movably seated on a floor plate by means of a joint connection, a sensor linked to a switch element, and a repositioning means disposed between the floor plate and the pedal. The repositioning means ensures that an operating force must be applied to the upper surface of the pedal to produce a tilting movement of the pedal out of an initial position into an operating position in which a smaller angle is defined between the floor plate and the pedal than in the initial position and in which the sensor is activated to trigger the output of a switch pulse from the switch element. A common feature of known arrangements similar to this is that during operation corrosion develops in the foot switch, in particular in the joint region, which interferes with operation of the switch so that the arrangement does not move freely and therefore is in a deficient functional state.
