    • A medical instrument for dissecting tissue in the human or animal body comprises a shaft. At least one movable tool is arranged at a distal end of the shaft. At least one movable grip element is arranged at a proximal end of the shaft. A force transmission element extends along the shaft, which force transmission element is movable relative to the latter and transmits thrust and/or tension forces and whose proximal end is non-positively joined to the at least one movable grip element and whose distal end is non-positively joined to the at least one movable tool. The shaft is further provided with a bend at least one point between the distal end and the proximal end. The force transmission element is configured, at least in the region of the bend, as a flexible tubular element conforming to the bend, which is guided in contact with the shaft. According to a second variant, a flattened and flexible configuration is given to the force transmission element in the region of the bend, at least locally transversely to the plane of curvature of the bend, and the force transmission element extends continuously in axial direction, transversely to the plane of curvature, at least over the inner diameter of the shaft in the region of the bend.
    • 用于解剖人或动物体中的组织的医疗器械包括轴。 至少一个可移动工具布置在轴的远端。 至少一个可动夹紧元件布置在轴的近端。 力传递元件沿着轴延伸,该力传递元件相对于该传动元件可移动,并且传递推力和/或张力,并且其近端与所述至少一个可动把手元件非正向接合,并且其远端不是 - 正向连接到所述至少一个可移动工具。 轴还在远端和近端之间至少有一个点设有弯曲部。 至少在弯曲区域中,力传递元件被构造为与弯曲部接触的引导件的柔性管状元件。 根据第二种变型,在弯曲区域中至少部分横向于弯曲曲面的局部向力传递元件施加平坦且柔性的构造,并且力传递元件在轴向方向上连续延伸 至少在弯曲区域内的轴的内径上。

    • A seal for a trocar sleeve comprises a sealing body which, in the direction of a longitudinal center axis of the sealing body, has a first axial end and a second axial end and, between said first and second ends, an elastic sealing element which, in a radially inner area relative to the longitudinal center axis, defines a passage for an instrument. Said sealing element has a substantially tubular hollow space whose radially inner wall area annularly surrounds the passage, and said hollow space contains a fluid and and has a radially inner wall area annularly surrounding the passage, and a radially outer wall area on a radially outer side of the hollow space, the radially outer wall area having a wall thickness larger than a wall thickness of the radially inner wall area.
