Abstract: An instrument for a robotic surgery system that includes a housing and an outer shaft joined to an effector at a distal end, and to the housing at a proximal end. The connection is rotatory so that the outer shaft can rotate about its longitudinal axis. The rotatory connection takes place by way of a first coupling element that is fixed to the outer shaft. The instrument also includes a first inner shaft arranged within the outer shaft and movably supported relative to it. The relative motion may be either a rotation or translation. The first inner shaft is joined with the effector at a distal end and fixed to a second coupling element at a proximal end. The first coupling element encloses the first inner shaft in a first transition region at the proximal end of the outer shaft, and a first sealing element encloses the first inner shaft.

Abstract: The disclosure relates to a machine system, in particular a packaging and/or processing machine, which comprises at least one input/retrieval device for inputting a first group of parameters of a complete set of parameters comprising the first group and at least a second group of parameters as adjustment parameters for operating the machine. The second group of parameters can be transmitted to the input/retrieval device from the Internet, where the number of and/or changes to the parameters of the first group can be selected/or determined via the Internet. As a result, a respective machine system is improved in such a way that a user of the machine system can be given limitations when adjusting his machine system in order, for example, to enable a usage and/or function-based billing model.

Abstract: A surgical instrument having a long shaft comprises, in the shaft, a sealing element produced by primary shaping at the installation location. The sealing element is produced such that any actuating mechanisms are installed and held in place in the shaft and then a curable plastic material is injected into the shaft such that the material encloses the actuating element along a length that is greater than the inside diameter and smaller than its length.

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.

Abstract: The invention relates to double trimming shears having a stationary bottom knife and a driven top knife which can be raised and lowered, wherein the top knife is arranged on a top knife carriage (12) guided by means of a carriage guide (10), wherein a first eccentric shaft (14) and a second eccentric shaft (16) on the carriage guide (10) is provided in order to guide the carriage guide (10) if an inclined position of the top knife carriage is to be prevented. This is achieved in that the first eccentric shaft (14) and the second eccentric shaft (16) are interconnected via a synchronization means (18).

Abstract: A device for connection of a line element to a component is provided. The line element ends in a connection housing or is connected to such a connection housing. A releasable fixing arrangement is configured between the connection housing and the component. A line section extending in the connection housing is heated by an electric heating wire. The heating wire externally surrounds the line section. The heated line section projects in the direction of the component so far over the region for releasable fixing of the connection housing on the component that it ends in the inner space of the component.

Abstract: A surgical instrument that comprises at least one microcontroller arranged in the handle of the instrument and that communicates with the surgical apparatus—without the interposition of a radio link via the cable that already exists between the surgical apparatus and the surgical instrument. Safe data transmission is ensured not only in the high-interference environment of an active RF surgical apparatus, but also in, for example, water jet, argon plasma and cryosurgical apparatuses, endoscopes. A differential transmission technique is selected, wherein one or more conductor pairs (insulated conductors) are utilized, one of the conductors of said conductor pairs transmitting the signal and the other transmitting the inverted signal. By subtracting the two signals, the actual data signal is yielded on the receiver side. If feedback interferences from the environment act on the data transmission link, the subtractions performed on the respective receivers cancels out the interferences.

Abstract: With known trimming shears having a pair of scrap-cutting blades on the discharge side, the moving upper scrap-cutting blade must be moved as closely as possible past the trimmed plate edge in order to push the cutoff edge still hanging on the plate downward against the lower fixed scrap-cutting blade, which requires precise adjustment of the upper scrap-cutting blade. To that end, according to the invention, the distance between the upper scrap-cutting blade (2) or the lower scrap-cutting blade (3) and the trimming blade plane (5) is set prior to trimming in accordance with the thickness of each heavy plate (10) to be trimmed by displacement of the upper scrap-cutting blade (2) and/or the lower scrap-cutting blade (3) in a displacement direction with at least one component transverse to the trimming blade plane (5).

Abstract: A method of operating a rinsing pump, for example, a peristaltic roller pump for use in endoscopy, which involves reducing a rinsing fluid flow rate to a safe flow rate when a detected electrical current exceeds a first predetermined current value, in which the first predetermined current value corresponds to a first predetermined limiting rinsing pressure. The method in part prevents an excessively high pressure in case of an unintended stenosis, e.g., kinking of the supply tube, or also intended stenoses, e.g., insertion of a narrow rinsing probe, by detecting an electrical current received by the pump by a current-measuring device.
