带有触觉位置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，连接到所述端部执行器上的主动轴组件和连接到所述主动轴组件上的齿轮传动系。所述端部执行器包括用于切割定位在该端部执行器中的物体的可动切割器械。所述器械还包括用于致动所述齿轮传动系的主电动机和用于致动所述主电动机的击发触发器。所述器械还包括用于将力施加到所述击发触发器的触觉位置反馈系统，从而使该击发触发器的位置与所述端部执行器中的切割器械的位置相关。
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 connected to the end effector, and a gear drive train connected to the main drive shaft assembly. The end effector comprises a movable cutting instrument for cutting an object positioned in the end effector. The instrument also includes amain motor for actuating the gear drive train and a firing trigger for actuating the main motor. The instrument also includes a tactile position feedback system for applying force to the firing trigger such that the position of the firing trigger is related to the position of the cutting instrument in the end effector.
