A medical robotic system includes an entry guide with surgical tools and a camera extending out of its distal end. To supplement the view provided by an image captured by the camera, an auxiliary view including articulatable arms of the surgical tools and/or camera is generated from sensed or otherwise determined information about their positions and orientations are displayed along with indications of range of motion limitations on a display screen from the perspective of a specified viewing point.

A robotic surgical system is provided. The robotic surgical system includes a robotic mechanism having a force transmitting member and a computer connected with the robotic mechanism. The robotic surgical system also includes an optical sensing system connected with the computer, at least one navigation member configured to couple to one or more tissues of a patient, and a tool suitable for use in resecting at least a portion of a first bone of a joint in a patient and at least a portion of a second bone of the joint in the patient.

A surgical end effector may comprise first and second jaw members. The second jaw member may comprise an offset proximal supply electrode that is positioned to contact an opposing member of the first jaw member when the first and second jaw members are in the closed position. The second jaw member may also comprise a distal supply electrode that is positioned distal of the offset proximal electrode and is aligned with a conductive surface of the first jaw member when the first and second jaw members are in the closed position. When the first and second jaw members are in the closed position, the proximal supply electrode may be in contact with the opposing member and the distal supply electrode is not in contact with the conductive surface of the first jaw member.

A controller for an electrosurgical device and related methods and devices are disclosed. The controller has a processing component to: (a) derive a power factor of power applied to the electrosurgical device; and (b) responsive to the deriving a power factor, assign a circuit status to a circuit comprising the electrosurgical device. IF (PF0) and ((Vrms/Irms)T), THEN the circuit status is open. IF (PF0) and ((Vrms/Irms)<T), THEN the circuit status is short. PF is the power factor. Vrms is the root mean square of a voltage associated with the power applied to the at electrosurgical device. Irms is the root mean square of a current associated with the power applied to the electrosurgical device. T is a threshold value.

A robotic system for use in performing an arthroplasty procedure of a patient is provided. The robotic system includes a robotic mechanism, a cutting tool coupled to the robotic mechanism for resecting a portion of a bone of the patient through an incision in the skin of the patient, and a computer coupled to the robotic mechanism and configured to control the robotic mechanism. The robotic system also includes at least one navigation member positionable into engagement with tissue in the patient, an optical system coupled to the computer, a position sensor configured to provide movement information of the robotic mechanism relative to the bone, and an interface coupled to the computer, the interface configured to operate the computer.

The present invention is directed to a surgical instrument with a robotics system, a memory device and an end effector having an elongate channel, knife position sensor(s) and a firing bar coupled to a knife. In response to drive motions initiated by the robotics system, the firing bar may translate within the elongate channel. As the firing bar translates, the sensor(s) transmit a signal to the memory device. The position of the knife may be determined from the output signals and may be communicated to the robotics system or instrument user. The sensors may be Hall Effect sensors.

A robotic system has a flexible portion adapted for insertion into the gastrointestinal tract and includes a suturing system with a needle holder. An actuator is coupled to the needle holder and is adapted to act on the needle holder arm and needle such that the needle can be repeatedly moved through a path. The actuator is driven by a drive mechanism from the robotic system.

The present invention relates to an assistant robot for spine surgery, including: a surgical tool support provided with a rotating body to which the surgical tool is penetratingly coupled; a handle provided at one side of the surgical tool support; a driving member configured to rotate the rotating body; and a linear guide provided at the other side of the surgical tool support so as to move the surgical tool forward and backward. Accordingly, the surgical tool can smoothly move without vibration when moving forward and backward, and can be automatically rotated with uniform force so as to enable sophisticated surgery.

A motion system for a vascular intervention navigation surgery system is configured to control the motion of the vascular intervention navigation surgery system. The motion system has a support base and the vascular intervention navigation surgery system. The motion system provides more degrees of freedom of motion and other functions for the vascular intervention navigation surgery system, guidewires, catheters, stents, etc., making it more convenient to perform vascular intervention surgery. The motion system further includes a force reproduction system for the vascular intervention navigation surgery system. The force reproduction system can effectively detect a resistance of the guidewire in blood vessels, and by processing the resistance, determine the further movement status of the guidewire, thereby improving the safety and operational efficiency of vascular intervention surgery.
