Abstract

A robotic system includes an electrosurgical instrument having an instrument housing having a shaft with an end effector assembly and first and second jaw members attached thereto movable to grasp tissue. An input is operably coupled to the instrument housing and is configured to move the jaw members. A handle is remotely disposed relative to the instrument housing and is configured to communicate with the input for controlling the jaw members, the handle having a lever configured to cooperate with the input to control the jaw members relative to movement of the lever. The lever moves between a homing position and a first position correlating to the jaw members closing with a pressure therebetween in the range of about 0.1 kg/cmto about 2 kg/cm. The lever further movable to a seal position correlating to the jaw members closing about tissue with a pressure between about 3 kg/cmto about 16 kg/cmfor sealing.
