    • An exemplary surgical instrument comprises a handpiece, an end effector, and an activation and control feature that is operable to selectively activate an end effector and select an energy level for the end effector. One version of the activation and control feature includes a “floating” button feature where activation and control is accomplished based on the displacement of the button from a home position. In some versions the activation and control feature is sealed within the handpiece, but controllable by the user's touch with the handpiece. The sealed configuration can allow the handpiece to be sterilizable, e.g., using steam sterilization. The activation and control feature may comprise capacitive switches, resistive sensors, resonant cavity switching technology, infrared sensing technology, technology that uses a resonant standing wave on a surface that is perturbed by the presence of a finger, and/or any other suitable type of technology.
    • 示例性外科器械包括手持件,末端执行器和激活和控制特征,其可操作以选择性地激活末端执行器并为端部执行器选择能量水平。 激活和控制功能的一个版本包括“浮动”按钮功能,其中基于按钮从原始位置的位移来实现激活和控制。 在一些版本中,激活和控制功能被密封在手机内,但是可以通过用户与手持件的触摸来控制。 密封构造可以允许手持件可以消毒,例如使用蒸汽灭菌。 激活和控制特征可以包括电容式开关,电阻式传感器,谐振腔切换技术,红外感测技术,在由手指的存在所扰动的表面上使用共振驻波的技术和/或任何其它合适类型的 技术。
