Performing Robot-Assisted Surgery with LabVIEW
Print
The Challenge
Training surgeons to perform robot-assisted laparoscopic surgery with the da Vinci Surgical System (dVSS).
The Solution
Using NI LabVIEW software to develop a platform to ensure robot-assisted surgery is performed correctly.
Using the dVSS, the surgeon operates while seated at a console viewing a 3D image of the surgical field.
The advent of robotic assistive surgery using the dVSS from Intuitive Surgical Inc. has helped surgeons overcome some of the limitations of manual laparoscopy. In robot-assisted laparoscopy, the surgeon sits at a console and remotely controls endoscopic instruments via a surgical robot. The 3D visualization provides depth perception, and the robotic manipulators increase dexterity not available during manual laparoscopic surgery.
At the Nebraska Biomechanics Core Facility of the University of Nebraska at Omaha, we are collaborating with the Robotic Surgical Laboratory at the university’s medical center to develop a training program for new surgeons. Using LabVIEW, we acquire all the information from the robotic surgical system by connecting with the dVSS via TCP/IP. We use the NI USB-6009 data acquisition device to connect the electromyography system and electrogoniometers to acquire physiological measurements such as muscle activations and joint angles from the surgeons. With this system, researchers and medical personnel can objectively evaluate surgical proficiency before and after the robotic surgical training protocol.
We also used LabVIEW to create visual real-time feedback to show trainees how much force they apply on the training task or animate tissue. This visual feedback helps trainees reduce tissue damage inflicted during the procedure.
