Abstract (en)
[origin: WO2021206852A1] A surgical instrument includes an ultrasonic transducer supported by a housing and an elongated assembly extending distally therefrom. The elongated assembly includes a jaw and a waveguide coupled to the transducer and defining a blade having upper and lower tissue-contacting surface and first and second lateral surfaces disposed therebetween that are coated with a material. The jaw is pivotable relative to the blade and includes a structural base having a backspan and first and second uprights extending from the backspan. The jaw further includes a jaw liner supported within the structural base and positioned to oppose the upper tissue-contacting surface with the first and second uprights disposed on either side of the blade. In an ultrasonic mode, ultrasonic energy produced by the transducer is transmitted along the waveguide to the blade. In an electrosurgical mode, electrosurgical energy is conducted between the blade and the first and second uprights.
