摘要：
Methods and devices are provided for controlling movement of an end effector assembly, and in particular for causing mimicking motion between a handle and an end effector assembly. In an exemplary embodiment, a surgical device is provided having a handle or actuator, an elongate shaft, and an end effector assembly coupled to a distal end of the elongate shaft. The handle or actuator is configured such that movement of the handle is mimicked, not mirrored, by the end effector assembly. The mimicking motion can be achieved using various techniques, but in an exemplary embodiment the handle is located distal to an input joint, and motion is transferred to the end effector assembly through an output joint at a distal end of the elongate shaft. The motion is preferably transferred using a mechanical transmission coupled between the input and output joints.
