手术器械组、特别是机器人引导的手术器械的传动器组和手术器械
摘要：
根据本发明的一个方面，手术器械组具有：模块化的电机驱动的驱动单元(1)，其具有包括至少一个从动元件(10A，10B；100；1000)的从动器组；和器械杆(2)，其可松脱地与驱动单元相连接，并具有包括至少一个驱动元件(20A，20B；200；2000)的驱动器组，其中，从动器组和驱动器组通过机械接口彼此联接，接口具有：至少一个单侧连接(10A‑20A，10B，20B)；榫形件(100)和凹部，其中，榫形件在所述凹部中径向扩展，特别是有弹性地和/或通过至少一个单独的本体(100.1)径向扩展；和/或在榫形件和凹部之间构成沿径向方向呈波浪状的间隙，在间隙中设有可径向移动且轴向固定的中间元件组(100.7)；和/或翻转杠杆(1000)。
摘要（英）：

A surgical instrument arrangement has a modular motor drive unit which has a drive arrangement having at least one output element, an instrument shaft that can be detachably connected to the drive unit, and a drive arrangement having at least one input drive element. The output drive arrangement and the input drive arrangement can be coupled to each other by a mechanical interface that has at least one single-sided linkage, a pin, and a cut-out, wherein the pin can be radially expanded in the cut-out. Alternatively, a gap may be formed between the pin and the cut-out, which gap is wavy in the radial direction, and in which a radially displaceable, axially fixed intermediate element arrangement is arranged. The surgical instrument arrangement may also include a sterile barrier, which is provided to envelop the drive unit and to be arranged between the drive unit and the instrument shaft.
