用于外科手术器械的力传递机构以及相关系统和方法
摘要：
一种用于外科手术器械的力传递机构包括蜗杆传动装置、杠杆臂以及致动元件。该杠杆臂可以包括位于该杠杆臂的第一端处的从动构件。该从动构件接合该蜗杆传动装置并且被构造成由该蜗杆传动装置驱动。该致动元件连接到该杠杆臂。该致动元件被构造成传递力以致动该外科手术器械的末端执行器。该蜗杆传动装置的旋转运动经由该杠杆臂使该致动元件具有平移运动。
摘要（英）：

A force transmission mechanism for a surgical instrument includes a worm drive, a lever arm, and an actuation element. The lever arm may include a follower member at a first end of the lever arm. The follower member engages the worm drive and is configured to be driven by the worm drive. The actuation element is connected the lever arm. The actuation element is configured to transmit force to actuate an end effector of the surgical instrument. Rotational movement of the worm drive imparts translational movement to the actuation element via the lever arm.
