Abstract
An electrosurgical instrument for use in a robotic surgical system includes an electrosurgical end effector, a housing configured to be operably coupled to an instrument drive unit, a shaft extending distally from the housing, and a wrist assembly coupled to a distal end portion of the shaft. The wrist assembly includes a first pivot member and a second pivot member having a proximal end portion movably coupled to the first pivot member, and a distal end portion configured to be coupled to the end effector. The first pivot member has a pair of first and second distally-extending arms each defining a first groove configured to receive and guide a cable.
