US 2026/0198952 A1 · Articulating Multifunction Surgical Instruments Such as For Use in Surgical Robotic Systems

Abstract

A surgical instrument includes a housing including four input actuators, a shaft assembly including a proximal shaft and an articulating section disposed at a distal end of the proximal shaft, and an end effector assembly coupled to the articulating section. Articulation of the articulating section articulates the end effector assembly relative to the proximal shaft. The end effector assembly includes a proximal body, first and second jaw members extending distally from the proximal body, and an energizable element selectively deployable relative to the first and second jaw members from a retracted position to a deployed position, wherein the energizable element extends distally from the first and second jaw members. At least one of the first or second jaw members is movable relative to the other and the proximal body from a spaced-apart position to an approximated position to grasp tissue therebetween.
