具有加载力反馈的电动外科切割和紧固器械
摘要：
本发明公开了一种外科切割和紧固器械。根据各实施方式，所述器械包括端部执行器，主动轴组件和手柄。所述手柄包括连接到所述主动轴组件的齿轮传动系，用于致动所述齿轮传动系的电动机，以及击发触发器。所述击发触发器的回缩致动所述电动机。而且，所述击发触发器被连接到所述齿轮传动系，从而使施加到该击发触发器上的加载力与所述端部执行器中的切割器械体验的加载力相关。
摘要（英）：

A surgical cutting and fastening instrument is disclosed. According to various embodiments, the instrument includes an end effector, a main drive shaft assembly, and a handle. The handle comprises a gear drive train connected to the main drive shaft assembly, a motor for actuating the gear drive train, and a firing trigger. Retraction of the firing trigger actuates the motor. Further, the firing trigger is connected to the gear drive train such that the loading force applied to the firing trigger is related to the loading force experienced by the cutting instrument in the end effector.
