    摘要： Surgical methods and devices allow closed-chest surgery to be performed on a heart of a patient while the heart is beating. A region of the heart is stabilized by engaging a surface of the heart with a stabilizer without having to stop the heart. Motion of the target tissues is inhibited sufficiently to treat the target tissues with robotic surgical tools which move in response to inputs of a robotic system operator. A stabilizing surface of the stabilizer is coupled to a drive system to position the surface from outside the patient, preferably by actuators of the robotic servomechanism. Exemplary stabilizers includes a suture or other flexible tension member spanning between a pair of jointed bodies, allowing the member to occlude a coronary blood vessel and/or help stabilize the target region between the stabilizing surfaces.

    摘要： Improved robotic surgery end-effectors include at least one insulation material for inhibiting surface conduction of electrical current in a proximal direction, from a distal active electrode toward the proximal end of the end-effector and toward the rest of the surgical instrument itself. Some embodiments include two layers of insulation to further prevent proximally-directed current. By inhibiting proximal current flow, the end-effectors prevent unwanted patient burns as well as electricity-related wear and tear in and around the area where the end-effector is coupled with the rest of the surgical instrument. In various embodiments, such end-effectors are preferably removably coupleable with a robotic surgical instrument.

    摘要： The present invention provides improved electrosurgical instruments and systems having electrocautery energy supply conductors that provide inhibited current leakage and methods of performing a robotically controlled minimally invasive surgical procedure while preventing unintended capacitive coupling. A surgical instrument generally comprises an elongate shaft having a proximal end and a distal end and defining an internal longitudinally extending passage. An electrocautery end effector is coupled to or disposed at the distal end of the shaft. An interface or tool base is coupled to or disposed at the proximal end of the shaft and removably connectable to the robotic surgical system. Typically, an independent electrical conductor extends from the interface to the end effector to transmit electrical energy to tissue engaged by the end effector. A sealed insulation tube extends within the passage and over the conductor. A separation is maintained between the sealed insulation tube and the conductor.
