Visual performance and motor skills are a function of depth perception allowing for improved discrimination and recognition. The da Vinci Robot System has a true 3D imaging system that is considered to be one of the major advantages of robotic surgery. However, the assistants working on the patients′ side have to depend 2-dimensional (2D) images projected onto a flat screen monitor, in which they must rely on indirect cues to assist in depth perception for accurate and efficient movements. We developed a new 3D system on a flat high-quality screen with polarized glasses for the da Vinci system. This study was designed to evaluate the impact of 3D vision on the performance of assistants using this 3D system. METHODS We developed a new control box that can translate the da Vinci 3D signals to the 3D signals for a flat screen. They are projected onto the same screen through different polarizing filters (Figure). The assistants wear polarized glasses. Since no head tracking is involved, several assistants can view the stereoscopic images at the same time. Six surgeons varying experience performed three tasks with laparoscopic devices as laparoscopic training. In task 1, 3-0 Monocryl was passed though 7 holes. In task 2, 9 small elastic bands were transferred from 1 cylinder to others. In task 3, suture was performed using 3-0 Vicryl. Performance times were recorded using both 2D and 3D vision for each task. RESULTS Performance times in task 1, 2 and 3 were reduced by 84%, 56% and 10% using 3D imaging, respectively. Performance time for all 3 skills confirm a significant advantage using 3D vision. CONCLUSIONS Three-Dimensional vision allows for improvement in performance times using a new 3D system on a flat screen with polarized glasses for the da Vinci system. The use of 3D visualization seems to improve the efficiency of assistance during robotic surgery. Because of the high quality 3D vision provided for several assistants, this system has the potential to be used as teaching aids in robotic surgery. © 2011 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 185Issue 4SApril 2011Page: e600 Advertisement Copyright & Permissions© 2011 by American Urological Association Education and Research, Inc.MetricsAuthor Information Kazushi Tanaka Kobe, Japan More articles by this author Minori Matsumoto Kobe, Japan More articles by this author Tomihiko Yasufuku Kobe, Japan More articles by this author Katsumi Shigemura Kobe, Japan More articles by this author Kohei Yamaguchi Kobe, Japan More articles by this author Tomoaki Terakawa Kobe, Japan More articles by this author Takeshi Ishimura Kobe, Japan More articles by this author Mototsugu Muramaki Kobe, Japan More articles by this author Takahiro Haraguchi Kobe, Japan More articles by this author Junya Furukawa Kobe, Japan More articles by this author Yuzo Nakano Kobe, Japan More articles by this author Hideaki Miyake Kobe, Japan More articles by this author Masato Fujisawa Kobe, Japan More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
