  • Patent number: 10642838
    Abstract: Technologies are described for acquiring and processing data related to a production process, including to generate a report of variances between planned values and actual values. Data can be received from a plurality of data sources, such as hardware sensors, associated with the production process. The data can be sent in real time, such as in response to a request or upon the occurrence of a particular event. The data can be received and stored in one or more database tables having a format. The format can be the same format as a format in which planning data is maintained. When maintained in a common format, comparisons of planning and actual data can be carried out faster and with less processor use. Reports can include granular data, such as variances associated with particular data sources, or groups of data sources.

  • Patent number: 9757138
    Abstract: An instrument (10) having a tool (15) of a particularly simple design comprises jaws (16, 17) with jaw supports (46) supported by spaced-apart hinges on a shared socket part 18. The hinge axes (27, 28) of the hinges are oriented parallel relative to each other and are at a distance from each other. A slit (24) for precisely guiding a knife (25) may be provided between the two. The jaw supports (46) of the jaws (16, 17) are guided in their own hinges with minimal play and hence in a precise manner. They are held against each other by transverse interlocking means (37), thereby ensuring a simple assembly and precise guiding.

  • Patent number: 9216052
    Abstract: An instrument suitable for minimal invasive surgery. The instrument can be introduced into a body, for example, through a trocar, and has two arms and a centrally guided knife for clamping vessels. The central guidance of the knife in at least one of the arms avoids disadvantages that could otherwise develop as a result of the off-center severing of coagulated tissue. Moreover, the clean central guidance of the knife results in lower wear on the knife. Thus, a better cut quality and a longer service life of the knife can be achieved.

  • Patent number: 9144448
    Abstract: The medical instrument includes a male instrument connector, which includes at least one male fluid connector arranged on a flat face. A venting bore may also be arranged on the same face and disposed to act as pressure relief by which leaking fluids that accumulate in the instrument can be discharged. A cover cap may be attached to the face. The cover cap allows for sterilization of the instrument, including the male instrument connector.

  • Patent number: 9138251
    Abstract: A surgical instrument for performing water jet surgical operations comprises a nozzle that can be moved via a hydraulic actuator out of a retracted or passive position into a moved-forward or active position. The actuation is accomplished using hydraulic fluid that is supplied to the instrument head via a tube and/or hose. The fluid (e.g., a sodium chloride solution) that is to be injected into the tissue can be used as the hydraulic fluid that is supplied to the nozzle. High-frequency (HF) current can additionally be applied to the nozzle. The HF current can be conducted to the nozzle via a line extending through the fluid conducting element or via the electrolyte present therein.

  • Patent number: 9044545
    Abstract: A fluid applicator is fed by a fluid delivery arrangement containing an energy storage such as a pressure vessel. The gas pressure acts on a container that has been prefilled with the ejection fluid. The fluid to be ejected is thus subject to constant pressure. With a valve, the user can initiate the ejection of the desired amount of fluid with constant intensity. The check valve may also be a regulating valve which can be used by the user to vary the intensity of the effect. The user need only release the system, e.g., by puncturing the pressure vessel, to then be able to directly inject the fluid in a defined or metered manner via the probe, i.e., the fluid applicator. It is also possible to configure the entire injection device as a single-use system and to prefill the fluid applicator up to its fluid exit opening.

  • Patent number: 8843403
    Abstract: Methods and computer systems are provided managing and valuating inventory. In one embodiment, a computer system may assign every item of goods which is entering a working process to an identifier. The computer system may then track the goods in the working process. Further, the computer system may update a given identifier when the goods assigned to this identifier enter another stage in the working process, assign at least one price to each stage in the working process, determine the content of one or more identifiers, and calculate a price for goods in the working process.

  • Publication number: 20140107683
    Abstract: A fluid-surgical instrument includes a nozzle (20) to which a vibration can be applied. This concept can be used for changing the direction of the jet during the operation of the nozzle to generate an artificial wiping motion or to impart the nozzle with only micromovements that inject into the fluid jet a transverse pulse and thus lead to a change of the jet image. It is possible to combine both effects with each other. In this manner, the surgeon can retrieve, on command, e.g., different jet shapes made available by software technology and generate such jet shapes with one and the same instrument. In doing so, the surgeon can achieve varying effects without having to change the instrument and the nozzle.

  • Patent number: 8679143
    Abstract: An appliance for water-jet surgery is provided that includes a plurality of supply cylinder and piston arrangements in each of which is stored a working fluid that can be expelled, by means of the piston, through an outlet into a pressure conduit. At least one actuation device is provided to actuate the piston of each supply cylinder. By means of a change-over device to change the actuation from the piston of one supply cylinder to the piston of another supply cylinder, it is ensured that the working fluid can be expelled into the pressure conduit from consecutively emptying supply cylinders. As a result, an apparatus with a small structure that is achieved by simple means is disclosed.

  • Patent number: 8636725
    Abstract: A surgical instrument comprises a tool part and a grip part connected to each other via a ball and socket joint or other double-axis joint. The double axis joint allows the surgeon to work in a non-fatiguing, ergonomic and sensitive manner. The tool on the tool part can be activated e.g., mechanically by an actuation member. Additional actuation elements such as, e.g., electrical switches, can be arranged on the grip part to activate the tool. The transmission connection between the grip part and the tool can be achieved via rigid levers and connecting pieces or also via flexible elements (e.g., a traction cord), or rigid components with an integral hinge. To uncouple a pivoting movement of the grip part towards the tool part from an actuation of the tool, at least one joint of the transmission is arranged in the center of the joint.
