“…7,8 All published validation studies have come from a single institution, Roswell Park Cancer Institute (Buffalo, NY). It has both validated basic orientation modules (camera and arm movement, clutch, and fourth arm manipulation) as well as basic skill modules (suturing and tying, vessel clipping, and suture cutting).…”

“…In the face validation study for RoSS, over half of the test subjects responded that, among the five categories evaluated, RoSS was either ''somewhat close'' or ''not close'' to the actual da Vinci surgical system. 7 In addition, in the Conclusions section of the one validation study for SEP Robot, the authors state that improvements must be made in that system before implementation in a training curriculum. 13 According to Sweet et al, 24 the term validity itself has become a catch-all term that has led to justification for utilization in medical education, as long as a device proves a facade of face, content, and construct validity.…”

“…The face and content validity of the Robotic Surgical Simulator (RoSS) (Simulated Surgical Systems; Williamsville, NY) have been demonstrated. 7,8 The original software developed by Mimic Technologies for the second simulator, namely the da Vinci Trainer (dV-Trainer) (Mimic Technologies, Inc., Seattle, WA), has been recently adapted as a "back-pack" to be used with the Si console of the da Vinci robot, thus creating a third simulator, namely the da Vinci Surgical Skills Simulator (dVSSS) (Intuitive Surgical, Inc., Sunnyvale, CA). Although the construct validity of the dV-Trainer has been previously demonstrated, previous studies only included novices and experts, without a group of participants with intermediate level of robotic-assisted laparoscopic surgical expertise.…”

Objective: In this paper, we evaluate face, content and construct validity of the da Vinci Surgical Skills Simulator (dVSSS) across 3 surgical disciplines. Methods: In total, 48 participants from urology, gynecology and general surgery participated in the study as novices (0 robotic cases performed), intermediates (1-74) or experts (≥75). Each participant completed 9 tasks (Peg board level 2, match board level 2, needle targeting, ring and rail level 2, dots and needles level 1, suture sponge level 2, energy dissection level 1, ring walk level 3 and tubes). The Mimic Technologies software scored each task from 0 (worst) to 100 (best) using several predetermined metrics. Face and content validity were evaluated by a questionnaire administered after task completion. Wilcoxon test was used to perform pair wise comparisons. Results: The expert group comprised of 6 attending surgeons. The intermediate group included 4 attending surgeons, 3 fellows and 5 residents. The novices included 1 attending surgeon, 1 fellow, 13 residents, 13 medical students and 2 research assistants. The median number of robotic cases performed by experts and intermediates were 250 and 9, respectively. The median overall realistic score (face validity) was 8/10. Experts rated the usefulness of the simulator as a training tool for residents (content validity) as 8.5/10. For construct validity, experts outperformed novices in all 9 tasks (p < 0.05). Intermediates outperformed novices in 7 of 9 tasks (p < 0.05); there were no significant differences in the energy dissection and ring walk tasks. Finally, experts scored significantly better than intermediates in only 3 of 9 tasks (matchboard, dots and needles and energy dissection) (p < 0.05). Conclusions: This study confirms the face, content and construct validities of the dVSSS across urology, gynecology and general surgery. Larger sample size and more complex tasks are needed to further differentiate intermediates from experts. IntroductionThe American College of Surgeons has recommended simulation-based training for surgical trainees to increase proficiency and patient safety in light of recent restrictions to trainee work hours and increased concerns over patient safety.1 The first validated low-fidelity objective training and assessment tool for basic laparoscopic skills is the McGill Inanimate System for Training and Evaluation of Laparoscopic Skills (MISTELS), which has been adapted by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) for the Fundamentals of Laparoscopic Surgery (FLS) program.2 Currently, FLS certification is required for candidates applying for certification from the American Board of Surgery. Furthermore, construct validity of MISTELS has been established for urology trainees and attending urologists.3 Recently, the American Urological Association's Committee on Laparoscopy, Robotic and New Technology modified the original MISTELS/FLS program into a more urocentric curriculum, the Basic Laparoscopic Urologic Surgery (BLUS) skills curriculu...

Introduction: The trend of surgical robotics is to follow the evolution of laparoscopy, which is now moving towards singleincision laparoscopic surgery. The main drawback of this approach is the limited maneuverability of the surgical tools. Promising solutions to improve the surgeon's dexterity are based on bimanual robots. However, since both robot arms are completely inserted into the patient's body, issues related to possible unwanted collisions with structures adjacent to the target organ may arise. Materials and Methods: This paper presents a simulator based on patient-specific data for the positioning and workspace evaluation of bimanual surgical robots in the pre-operative planning of single-incision laparoscopic surgery. Results: The simulator, designed for the pre-operative planning of robotic laparoscopic interventions, was tested by five expert surgeons who evaluated its main functionalities and provided an overall rating for the system. Discussion: The proposed system demonstrated good performance and usability, and was designed to integrate both present and future bimanual surgical robots.
