The drive mechanism includes an actuator and a pair pulleys operatively coupled to the actuator to rotate about an axle. The first and second drive cables are coupled to the pulleys such that the drive cables extend on opposite lateral sides of the axle. A biasing mechanism is configured to bias the first and second pulleys to at least one discrete orientation to maintain the distal portion of the elongated shaft in a discrete articulated position.

  • Publication number: 20130072950
    Abstract: The present disclosure is directed to a fluid cooled ultrasonic surgical instrument and related systems and methods of use therefor. In some embodiments, the disclosed ultrasonic surgical instrument is adapted for used within an insufflated cavity or pneumoperitoneum of a patient. The instrument includes a housing having an elongate shaft, a waveguide disposed at a distal end of the shaft, a coolant inlet port defined in an outer surface of the housing, and a coolant pump disposed within the housing and configured to move coolant from the coolant inlet port to the waveguide. During use, insufflation gas from within the pneumoperitoneum is drawn into the instrument shaft by the coolant pump, and blown over the waveguide to provide cooling. The delivery of ultrasonic energy and activation of the pump may be controlled by a processor in response to user input and waveguide temperature.

  • Patent number: 8394095
    Abstract: Either an endoscopic or open bipolar forceps includes a flexible, generally tubular insulating boot for insulating patient tissue, while not impeding motion of the jaw members. The jaw members are movable from an open to a closed position and the jaw members are connected to a source of electrosurgical energy such that the jaw members are capable of conducting energy through tissue held therebetween to effect a tissue seal. A knife assembly may be included that allows a user to selectively divide tissue upon actuation thereof. The insulating boot may be made from a viscoelastic, elastomeric or flexible material suitable for use with a sterilization process including ethylene oxide. An interior portion of the insulating boot may have at least one mechanically interfacing surface that interfaces with a mechanically interfacing surface formed between the shaft and a jaw member or with a mechanically interfacing surface disposed or formed on the shaft or a jaw member.

  • Publication number: 20130041292
    Abstract: In accordance with the present disclosure, a system and method for using a remote control to control an electrosurgical instrument, where the remote controlled (RC) electrosurgical instrument has a universal coupling mechanism to allow switching between an interchangeable catalog of diagnostic tools. A controller within the base of the RC electrosurgical instrument identifies the type of disposable tip attached to the base. The controller, then, activates necessary features for use with the identified tip and deactivates any unnecessary features. A surgeon uses a remote with at least one momementum sensor to control the RC electrosurgical instrument 10. The surgeon rotates his hand mimicking movements of a handheld electrosurgical instrument, the movements of which are translated and sent to the RC electrosurgical instrument. The surgeon may use an augmented reality (AR) vision system to assist the surgeon in viewing the surgical site.

  • Publication number: 20130041368
    Abstract: A system and method for using a remote control to control an electrosurgical instrument, where the remote control includes at least one momentum sensor. As the surgeon rotates their hand mimicking movements of a handheld electrosurgical instrument, the movements are translated and sent to the remote controlled (RC) electrosurgical instrument. The surgeon uses an augmented reality (AR) vision system to assist the surgeon in viewing the surgical site. Additionally, the surgeon can teach other doctors how to perform the surgery by sending haptic feedback to slave controllers. Also, the surgeon can transfer control back and forth between the master and slave controller to allow a learning surgeon to perform the surgery, but still allow the surgeon to gain control of the surgery whenever needed. Also, the surgeon could be located at a remote location and perform the surgery with the assistance of the AR vision system.

  • Publication number: 20130038707
    Abstract: A system and method for improving a surgeon's vision by overlaying augmented reality information onto a video image of the surgical site. A high definition video camera sends a video image in real time. Prior to the surgery, a pre-operative image is created from MRI, x-ray, ultrasound, or other method of diagnosis using imaging technology. The pre-operative image is stored within the computer. The computer processes the pre-operative image to decipher organs, anatomical geometries, vessels, tissue planes, orientation, and other structures. As the surgeon performs the surgery, the AR controller augments the real time video image with the processed pre-operative image and displays the augmented image on an interface to provide further guidance to the surgeon during the surgical procedure.
