摘要：
An apparatus includes an end effector, an energy component, a control module, and a directional force sensor assembly associated with the energy component and control module. The directional force assembly can include a piezoelectric disc, a piezoresistive element, an accelerometer, and/or a Hall Effect sensor. The end effector of the apparatus can include ultrasonic blade, an RF electrode, or a staple driving assembly. In some versions, the energy component includes an ultrasonic transducer. The control module may be configured to operate the energy component at a first energy setting in response to a first detected force and at a second energy setting in response to a second detected force. The apparatus may also include an activation feature to be operated by a user. In some versions the piezoelectric disc may include a plurality of segments and may be configured to induce movement in at least part of the energy component.
