Summary:An apparatus for operating on tissue includes a body assembly, a shaft, an acoustic waveguide, and an end effector. The end effector includes an ultrasonic blade, a clamp arm, and a blade guard. The ultrasonic blade is in acoustic communication with the waveguide. The clamp arm is configured to pivot toward and away from the ultrasonic blade. The clamp arm has a first tine. The blade guard extends from the shaft. The blade guard has a longitudinally extending arm defining a concave pathway and a second tine located distal to the longitudinally extending arm. The ultrasonic blade is partially housed within the concave pathway. The first tine and the second tine are configured to grasp tissue when the clamp arm pivots toward the ultrasonic blade.
