  1. Robot-Assisted Laparoscopic Surgery - da Vinci System *Some of the slides adopted from: Amanda Neves University of Rhode Island Department of Computer, Electrical, and Biomedical Engineering by ShacharIlan

  2. Robot-Assisted Surgery • The Vision – Ridley Scott

  3. What is Laparoscopic surgery? • Minimally invasive operation performed in pelvis or abdomen through small incisions • Done for diagnostic purpose or to perform a surgical procedure

  4. Tools for Standard Laparoscopic Surgery • Digital laparoscope - Small Camera + Light source • Inserted through tiny tube (cannula) to see the operation • Abdomen is then inflated with carbon dioxide (not harmful to body) to raise abdominal wall above organs Click for video: https://www.youtube.com/watch?v=8vlKmnIVxZU

  5. Laparoscopic Surgery – Pros and Cons • Pros - Patients experience less pain, smaller chance of hemorrhaging, and shorter recovery time • Cons - Awkward motion for surgeon • Displaced hands and view • Requires surgeons to stands • Hard to learn – leads to complications with inexperienced doctors Open Surgery Scar Laparoscopy Scar

  6. da Vinci System - Console • Surgery is performed without any direct contact between surgeon and patient • Doctor sits away from operating table at an ergonomic, customizable computer console viewing 3D visual of operative region • Can theoretically be in another room (or another continent)

  7. da Vinci System - Robot • Multi-arm laparoscopic surgery robot replicates the surgeons’ motions with tiny tools inserted in the patients’ body through small incisions. • Surgeon's hand movements are scaled, filtered and translated the into more precise micro-movements of the instruments.

  9. Components of da Vinci System • Dual consoles allows doctors to collaborate in a very small space. • 7 DOF with wrist at tip of tool, allow for a very wide range of motion, wider than a human hand. • A variety of tools can be mounted on robotic arms and switched easily. Tool positions can be memorized and re-positioned by system • Force applied can be limited electronically • Con – Surgeon gets no force feedback

  10. da Vinci System – Some Statistics • FDA Approved since 2000 • Approximately 300,000 da Vinci procedures performed yearly • Cost ~1.8M$ + ~150K$ Yearly Maintenance • 2000+ Systems installed worldwide • 1500 in USA, 5 in Israel • Most common procedures: • hysterectomies and prostate removals

  11. Pros and Cons of da Vinci System Pros • Can perform more delicate procedures • Does not leave a large surgical scar • More high risk patients can undergo surgery because it’s less invasive Cons • Cost - $1+ million • Steep learning curve • Expensive training • Inability to feel the tissue • Surgery with this system takes 40-50 minutes longer

  12. Future of Robotic Surgery – Possibilities • Tele-surgery • Haptics • Single incision port with miniature snake-like robotic arms • In-surgery guidance by fusing information from prior CT, PET, MRI etc. • Surgery performed first in simulator planning environment, then robot re-enacts successful surgery on patient • Far future –Semi/Fully automated surgery
