Publication number: 20180256191Abstract: 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.Type: ApplicationFiled: May 8, 2018Publication date: September 13, 2018Inventors: ANTHONY B.

Publication number: 20170135775Abstract: 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.m.Type: ApplicationFiled: January 31, 2017Publication date: May 18, 2017Inventors: James S.
