Abstract: A deployable retractor (1) with a folded-in configuration and a folded-out configuration is provided. In the folded-out configuration, the refractor (1) forms a completely encased channel (2), and the casing (3) of the channel (2) includes an at least partly double-walled textile (4) that surrounds a fluid interior (6) which has at least one fluid chamber (5) and can be filled with a fluid via a connection (7) and which is emptied in the folded-in configuration and is filled with the fluid in the folded-out configuration.

Abstract: An electrical connection includes several busbars designed for connecting an inverter to an electrical machine, each busbar having two fixation holes. A support designed for supporting the busbars includes grooves designed for respectively receiving the busbars, and for each groove, two fixation pins projecting from a bottom of the groove, designed for being respectively received in the fixation holes of the busbar received in the groove and for being riveted to fix the busbars to the support. Each fixation hole is larger than the fixation pin received.

Abstract: The invention relates to a surgical instrument with a grip area, which has a first handle part, which is fixed in the position of use, and a second handle part, which can be moved relative to the first handle part along an adjustment direction, wherein a ratio between a first distance between the first handle part and the second handle part and a second distance between the first handle part and the second handle part is constant or almost constant in the direction of the first handle part, at least over a partial area of the actuating path, during a movement of the second handle part.

Abstract: The invention relates to a surgical instrument for separating and removing a biopsy. A suction channel for suctioning the biopsy out of a distal region in the direction of a proximal region is formed in a shaft, and/or a cutting tool is formed in one distal region or the distal region of the shaft, said cutting tool having a stationary cutting part and a counter cutting part which can be adjusted relative to the stationary cutting part about a rotational axis formed by a rotary joint wherein the cross-section of the suction channel expands in the suction direction from the distal region to the proximal region and/or the rotary joint is formed by two securing elements, each securing element being introduced from the interior to the exterior.
