    • An actuation grip for a microsurgical instrument, with an inner shank, which is surrounded coaxially and cylindrically by an outer shank, wherein the shanks are axially movable relative to each other. Two pivotable grip parts, each with two ends, are coupled pivotably at a proximal end of the actuation grip. On each grip part, a first lever is articulated rotatably via an attachment point between the ends of the grip part, wherein the two first levers are coupled rotatably to each other at an intersection point between their ends. The first levers are each connected rotatably to a second lever at their ends directed away from the grip parts, such that the first levers form, with the second levers, a double scissor hinge which serves to move the two shanks axially relative to each other, in order to use this movement to actuate a surgical tool.
    • 用于显微外科器械的致动夹具,其具有通过外部柄部同轴和圆柱形地包围的内部柄部,其中所述柄部可相对于彼此轴向移动。 两个可枢转的握持部分,每个具有两个端部,在致动把手的近端可枢转地联接。 在每个抓握部分上,第一杠杆通过夹持部分的端部之间的附接点可旋转地铰接,其中两个第一杠杆在它们的端部之间的交叉点处可旋转地联接。 第一杠杆各自可旋转地连接到第二杠杆,其端部远离抓握部分,使得第一杠杆与第二杠杆形成双重剪刀铰链,其用于相对于彼此轴向地移动两个柄部, 以便使用该运动来致动外科手术工具。

    • A tool, which is detachably coupleable with a shaft for a micro-invasive surgical instrument, includes an articulated device on which a jaw member or other active device is affixed, a connecting component that is rotatably connected with the articulated device and that includes a coupling device for detachable coupling with a distal end of a shaft, a transmission rod to transmit at least either a force or torque from one proximal end of a shaft detachably coupled with the tool to the jaw member or other active device, and a locking device that is coupled with the transmission rod in such a way that the locking device can be rotated with respect to the transmission rod but not slid axially, so that the locking device is mounted in the connecting component in such a way that it can be axially slid but not rotated in relation to the connecting component.
    • 可拆卸地与用于微创手术器械的轴联接的工具包括铰接装置,其上固定有钳口构件或其他有源装置,连接部件,其与铰接装置可旋转地连接,并且包括联接器 用于与轴的远端可分离联接的装置,传动杆,用于将至少一个力或扭矩传递到与工具可拆卸地联接到颚构件或其它有源装置的轴的一个近端;以及锁定装置, 与传动杆联接,使得锁定装置可以相对于传动杆旋转但不能轴向滑动,使得锁定装置以可以轴向滑动的方式安装在连接部件中,但是 不相对于连接部件旋转。
