Evaluation of a virtual-reality-based simulator using passive haptic feedback for knee arthroscopy
Sandro F. Fucentese, Stefan Rahm, Karl Wieser, Jonas Spillmann, Matthias Harders, Peter P. KochSimulator training in orthopaedics is still in its infancy. The aim of this study is to determine face and construct validity of a new virtual reality simulator (VirtaMed ArthroS™) for diagnostic and therapeutic knee arthroscopy by analysis of simulator metrics of participants with varying arthroscopy experience.
Virtual reality simulator for training urologists on transurethral prostatectomy
ZHU He, ZHANG Yi, LIU Jin-shun, WANG Gang, YU Cheng-fan and NA Yan-qunAs a new method of training on transurethral prostatectomy skills, training of TURP using a virtual simulator can help urologists improve their surgical skills and safety. Therefore, the application of the TURPSim™ system in education and training of urologic surgery is warranted.
Reference Center Würzburg, Germany
As the very first hospital in Germany, König-Ludwig-Haus uses the arthroscopy simulator VirtaMed ArthroS™ for the education of resident physicians. The simulator is an inherent part of the curriculum and receives positive feedback from young surgeons. Dr. Stephan Reppenhagen also perceives a positive effect on the learning curve of young physicians, way before their first guided procedure in the operating room.
Reference Center University of Utah, USA
The University of Utah wanted to enhance surgical education in the orthopedic department. The goal is simply to use the latest educational means available for the training of young surgeons, i.e. virtual reality simulators. After comparing the different simulators currently on the market and their training abilities, the decision was clear. Watch the video below and see why Dr. Burks of the Department of Orthopaedic Surgery prefers the VirtaMed ArthroS™ arthroscopy simulator over other training tools.
Reference Center HELIOS hospital group, Germany
The HELIOS Hospital Group consists of 110 acute and rehabilitation facilities with about 34.000 beds and more than 69.000 employees. The departments for urology and gynecology train a large group of residents each year until they complete their education as medical specialists. In 2011, HELIOS included VirtaMed's virtual reality simulators into their standard curriculum for residents in training. E.g. in each urology department, a simulator is placed at the disposal of each clinic for six weeks each year. During this time, the head physician conducts a training program. In his or her first year, every surgeon who wants to conduct transurethral resection has to perform 50 documented procedures on the simulators.
Face validity, construct validity and training benefits of a virtual reality TURP simulator
Elizabeth Bright*, Samuel Vine, Mark R. Wilson, Rich S.W. Masters, John S. McGrathVirtual reality (VR) surgical simulators provide repetitive practice and performance feedback without requiring supervision in a safe environment. Simulators have the potential to shorten the learning curve for complex surgical procedures, create skills which transfer to the operating room and therefore decrease the incidence of future complications. Experts resected a significantly greater percentage of prostate per minute [...] and had significantly less active diathermy time without tissue contact [...] than novices.
Visual Control Strategies of Surgeons: A Novel Method of Establishing the Construct Validity of a Transurethral Resection of the Prostate Surgical Simulator
Elizabeth Bright, Samuel J. Vine, Thomas Dutton, Mark R. Wilson, John S. McGrathSignificant differences between experts and novices in both performance and visual control strategy were observed. The study of visual control strategies may be a useful adjunct, alongside measurements of motor performance, providing a novel method of assessing the construct validity of surgical simulators.
Learning effects using a TURP simulator: Assessing changes in visual control and performance
Samuel Vine, Thomas Dutton, Mark Wilson, Elizabeth Bright, John McGrathSurgical simulators afford trainees the chance to practice skills in a safe environment and without the need for supervision. Although they have been proposed to shorten the learning curve for complex surgical skills, there is concern that they do not prepare trainees for the demanding conditions of the operating room. Research in skill learning (including surgical skills) has shown that experts and novices can be distinguished by differences in their visual control strategies, with experts using fewer fixations of a longer duration. The aim of this study was to assess the learning benefits of a TURP simulator by examining, not only changes in novice performance, but also changes in their visual control.
Preliminary Experience with Virtual Reality Simulation vs. Animal Model for Hysteroscopic Myomectomy Training
L.R. Glazerman, S.R. Hart, M. Bajka, D. Fink, R.R. BassalyThe HystSim™ Virtual Reality hysteroscopic trainer was felt to be at least equal to the ‘‘gold standard’’ pig bladder model for training in hysteroscopic myomectomy with the additional advantages of reproducibility and measurement of results. Further studies comparing modalities and relating results to operating room performance are warranted.
Establishing Construct Validity of a Virtual-Reality Training Simulator for hysteroscopy via a Multimetric Scoring System
PD Dr. med. Michael Bajka, Dr. Stefan Tuchschmid, Daniel Fink, Prof. Dr. Gabor Szekely, PD Dr. Matthias HardersThe aims of this study are to determine construct validity for the HystSim™ virtual reality (VR) training simulator for hysteroscopy via a new multimetric scoring system (MMSS) and to explore learning curves for both novices and experienced surgeons.
Evaluation of a New Virtual-Reality Training Simulator for Hysteroscopy
PD Dr. med. Michael Bajka, Dr. Stefan Tuchschmid, Daniel Fink, Prof. Dr. Gabor Szekely, PD Dr. Matthias HardersFace validity has been established for a new hysteroscopic surgery simulator. Potential trainees and trainers assess it to be a realistic and useful tool for the training of hysteroscopy. Further systematic validation studies are needed to clarify how this system can be optimally integrated into the gynecological curriculum.
Broward HealthDr. Ivan Puente, MD, FACS Program Director said, "From the moment you walk up to the simulator you can set it up just like we do in the OR. We are able to mimic exactly what we do on the real patient. I like that we can add complications such a bleeding and bile leakage to better prepare residents for the OR. Clearly having the simulation before the operation enhances skills and improves patient safety."
Nancy Regional University Hospital, France"VirtaMed’s laparoscopic simulator delivers unparalleled levels of realism and will play an important role in preparing residents for real OR scenarios, including team training and management of complications. We compared many high-fidelity simulators and are confident that the LaparoS™ is the simulator with the highest potential." - Prof. Ahmet Ayav, Head of the Digestive Surgery Department
