    • An endoscope with an instrument housing and with a shaft that is mounted on the distal end of the instrument housing and consists of an outer tube and an inner tube that is mounted at least partly in the outer tube, so that the outer tube and the inner tube are mounted on the instrument housing so that they can move with respect to one another in the axial direction of the shaft. To provide an endoscope that ensures a constantly fluid-tight relative motion of the two shaft tubes with respect to one another, it is proposed with the invention that the outer tube and inner tube should be mounted on the instrument housing so that they are mobile with respect to one another in the axial direction of the shaft by means of at least one flexible membrane.
    • 一种内窥镜,其具有仪器壳体并具有安装在所述仪器壳体的远端上的轴,并且包括至少部分地安装在所述外管中的外管和内管,使得所述外管和所述内管 管安装在仪器壳体上,使得它们可以在轴的轴向方向上相对于彼此移动。 为了提供确保两个轴管相对于彼此不断流体密封的相对运动的内窥镜,本发明提出,外管和内管应安装在仪器壳体上,使得它们可移动, 通过至少一个柔性膜在轴的轴向上彼此相对。

    • A holder for optical components includes a two-part holder housing that forms an essentially ring-shaped enclosure surrounding an optical component; in addition the two housing parts have different thermal expansion coefficients. To create a holder for optical components that is both simple in structure and ensures a low-tension and insulated enclosure of the optical component, it is proposed with the invention that one housing part should be configured as a ring that surrounds the optical component and on whose housing interior close to the optical component a groove should be configured that surrounds and encloses the optical component and serves as a receptacle for the second housing part, which is configured as a tension ring.
    • 用于光学部件的保持器包括两部分保持器壳体,其形成围绕光学部件的基本上环形的外壳; 另外两个壳体部件具有不同的热膨胀系数。 为了创建一种结构简单并确保光学部件的低压和绝缘外壳的光学部件的支架,本发明提出一种壳体部件应当被配置为围绕光学部件的环并且 其壳体内部靠近光学部件,应该构造一个凹槽,该凹槽围绕并包围光学部件,并且用作构造为张力环的第二壳体部分的插座。

    • The invention relates to a medical instrument having a hollow shaft, a tool positioned on the distal end of the shaft consisting of a rigid jaw member and a jaw member that can rotate with respect to the rigid jaw member, as well as a handle positioned on the proximal end of the shaft. The tool and the handle are in active connection with one another by a push-pull rod mounted in the shaft, and the jaw members of the tool are mounted on one another by pins. It is proposed with the invention that the push-pull rod should be configured as a hollow slide tube mounted in the shaft so that it can slide axially and is in active connection with the rotatable jaw member by an actuation element that is essentially rod-shaped.
    • 本发明涉及一种具有中空轴的医疗器械,位于轴的远端上的工具,其由刚性钳口构件和能够相对于刚性钳口构件旋转的钳口构件以及位于 轴的近端。 工具和手柄通过安装在轴中的推拉杆彼此主动连接,并且工具的钳口构件通过销彼此安装。 本发明提出推拉杆应该被构造为安装在轴中的中空滑动管,使得其可以轴向滑动并且通过致动元件主动连接,该致动元件基本上是杆形的 。
