Updates on the RoSS II trainer

"The RoSS simulator was developed by Thenkurussi (“Kesh”) Kesavadas, PhD, professor of mechanical and aerospace engineering at UB, right; and surgeon Khurshid Guru, MD, director of the Center for Robotic Surgery at Roswell Park Cancer Institute."
  • "RoSS is a portable, stand-alone Robotic Surgery Simulator that teaches novice surgeons the motor and cognitive skills required for operating the da Vinci surgical robot.
  • The RoSS uses virtual reality to introduce the user to the fundamentals of robot-assisted surgery. It boasts a multi-level curriculum, designed with various levels of difficulty, that takes the user through and teaches the required skills for effectively advancing robotic surgery abilities. 
  • RoSS is the only robotic surgery simulator featuring full-length surgical procedures in 3D, otherwise known as HoST.
  • RoSS is portable, so novice surgeons are able to practice and train without using valuable OR space and time.
  What is new in Ross II   
  • The portable, stand-alone RoSS II console is a sleek redesign of the original RoSS that boasts improved graphics, enhanced visualization, smaller size, and decreased weight.      
  • NEW Improved Graphics     
  • NEW Improved Physics in Skills Modules     
  • NEW Superior Arm Motion and Interaction     
  • NEW Robotic Skills Assessment (RSA) Score 
Features and benefits      
  • Portable, stand-alone console can be setup anywhere.     
  • Integrated management system stores metrics for all users and tasks performed.     
  • HoST (Hands-on Surgical Training) modules use actual surgical cases for unparalleled realism.     Adjustability and usability customizable to each user.     
  • Proven track record of mechanical and electrical reliability.     
  • Ergonomically adjustable to each user     
Virtual Reality Based Training      
  • The RoSS II  simulator addresses the rapidly growing need for a realistic training environment for robot-assisted surgery by:         
  • Offering 16 modules with progressive difficulty from pinching, camera and clutch operation to tissue cutting and cautery         
  • Developing motor and cognitive skills for performing robot-assisted surgery         
  • Providing in-vivo virtual operative steps with three levels of complexity         
  • Storing performance metrics for all users in a comprehensive database for export to Excel"

Perception of da Vinci surgery

"We administered survey questionnaires via face-to-face interviews with surgical patients (n = 101), healthcare providers (n = 58), and senior members of hospital administration (n = 6) at a community hospital that performs robotic surgery. The respondents were asked about their perception regarding the infection rate, operative time, operative blood loss, incision size, cost, length of hospital stay (LOS), risk of complications, precision and accuracy, tactile sensation, and technique of robotic-assisted surgery as compared with conventional laparoscopic surgery. We then performed a comprehensive literature review to assess whether or not these perceptions could be corroborated with clinical evidence." An the results are worth looking into:

The GIFT Surg project

"UCL is working towards a major development in surgery on unborn babies thanks to a £10 million award from the Wellcome Trust and the Engineering and Physical Sciences Research Council (EPSRC), under the ‘Innovative Engineering for Health’ initiative.
This new research project, titled GIFT-Surg (Guided Instrumentation for Fetal Therapy and Surgery), is led by UCL in collaboration with KU Leuven in Belgium, who will work with surgeons and doctors at Great Ormond Street Hospital, University College London Hospital NHS Trust and UZ Leuven as part of a highly multidisciplinary team.
GIFT-Surg will engineer a novel combination of innovative interventional imaging systems and MRI/ultrasound scans to provide extremely accurate visualisation, both pre-operative and real-time, which will be used by the surgeon in conjunction with advanced surgical tools that offer new levels of flexibility and precision. A training platform will also be developed to equip surgeons with the necessary skills in the treatment of congenital birth defects such as spina bifida and twin-to-twin transfusion syndrome."
"GIFT-Surg is working to develop an extended flexible mechatronic multi-finger device that will be fed in through a small incision, of  approximately 4mm, in the abdomen of the mother. This device will enable surgeons to operate and perform complex procedures  from outside the womb. The three “fingers” of the device will offer the surgeon superior dexterity and better vision at the surgery  site. While two of the fingers can carry out delicate procedures, in the case of spina bifida, patching up the source of the protrusion  from the spine, the third will carry an innovative endoscopic imaging system that will create 3D images of the environment inside  womb and acquire tissue properties making it possible to identify anatomic structures on and below the tissue surfaces. The  surgeon will have direct and real-time access to these images and guidance cues which will be clearly displayed on a screen visible  to them in the operating theatre. The images will also serve as a feedback for guiding the dexterous instrumentised ar
Key Impacts include: 
  • Creation of flexible instru ments that are designed to allow surgeons to perform minimally invasive surgery  with improved safety and efficacy
  • Allow surgeons to actively and reliably work in a fragile, complex and real-time environment 
  • Enable surgeons to better prepare for surgeries by providing more pre-operative data 
  • Provide clearer visualisations and  greater scope of view for surgeons."
The project has already created some valuable open-source software packages.
