Abstract
A surgical instrument for use with a robotic surgical system is described. The instrument includes an elongate shaft having a proximal end and a distal end. An electrically live wrist member is disposed at the distal end of the shaft. An electrocautery end effector is mounted to the wrist member. An interface is disposed at the proximal end of the shaft. The interface is removably connectable to the robotic surgical system. A conductor extends from the interface to the end effector so as to deliver electrical energy to tissue engaged by the end effector. A tip cover is disposed over the wrist member so that electrical current can only be conducted to tissues through the exposed end effector (e.g., to promote blood coagulation during usage) and not to other parts of the patient's body.
