摘要： Aspects of the present disclosure are presented for a single surgical instrument configured to grasp, seal, and/or cut tissue through application of therapeutic energy, and also detect nerves through application of non-therapeutic electrical energy. A medical device may include two jaws at an end effector, used to apply therapeutic energy and to perform surgical procedures. The therapeutic energy may be in the form of ultrasonic vibrations or higher voltage electrosurgical energy. One of the jaws may be configured to cut tissue through application of the blade. In addition, one or both of the two jaws may be configured to apply nontherapeutic energy for nerve stimulation probing. The application of therapeutic energy may be disabled while the nontherapeutic nerve stimulation energy is applied, and vice versa. The nontherapeutic nerve stimulation energy may be applied to the use of one or more probes positioned near one or both of the jaws.

摘要： An apparatus for operating on tissue comprises a shaft, an acoustic waveguide, and an end effector. The acoustic waveguide extends along the shaft and is configured to transmit ultrasonic vibration. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is in acoustic communication with the acoustic waveguide. The clamp arm is pivotable toward the ultrasonic blade. The end effector defines a first longitudinal region and a second longitudinal region. The end effector is configured to clamp tissue between the clamp arm and the ultrasonic blade in the first longitudinal region. The end effector is configured to sever tissue with the ultrasonic blade in the second longitudinal region.
