    • The present invention is a telescopic drive device of a device for holding a surgical instrument. The telescopic drive device includes a support; a first telescopic stage carried by the support; a first telescopic stage carried by the support, the first telescopic stage being able to perform a first motion with respect to the support; a second telescopic stage, which is able to perform a second motion with respect to the first telescopic stage; and a drive system, which is operable to drive the first and second motions. The first telescopic element performs the first motion and the second telescopic element simultaneously performs the second motion. The telescopic drive is operable to support a further device and to move the further device such that the movement is centered around a point or wherein each of the telescopic elements is arcuate.

    • A clutch mechanism for use with a carrier of a linear drive device includes a housing, a first gear, and a first clutch arrangement. The first gear coupled to the housing and has gear teeth to engage a threaded shaft of a linear drive device. Rotation of the shaft causes the housing to move along the shaft in a first mode of operation. The first clutch arrangement prevents substantial rotation of the first gear. The first gear permits rotation of the first gear with respect to the housing. The housing can be manually moved along a length of the shaft, in a second mode of operation, by exerting a force on the housing. The rotational force applied to the first gear through the interaction of the threaded shaft and the gear teeth exceeds the first threshold.
    • 用于线性驱动装置的载体的离合器机构包括壳体,第一齿轮和第一离合器装置。 第一齿轮联接到壳体并具有啮合线性驱动装置的螺纹轴的齿轮齿。 轴的旋转使得壳体在第一操作模式下沿着轴移动。 第一离合器装置防止第一档位的大量旋转。 第一档允许第一档位相对于外壳旋转。 通过在壳体上施加力,壳体可以在第二操作模式中沿轴的长度手动移动。 通过螺纹轴和齿轮齿的相互作用施加到第一齿轮的旋转力超过第一阈值。
