“…Our findings are in accordance with previous studies on robotic camera holders [3,4,7,[15][16][17][18][19]. These studies have shown that robotic camera assistance is safe and that robotic camera holders enable the ability to perform laparoscopic procedures without camera assistance.…”

“…This can reduce the number of theatre staff members and could eventually lead to increased efficiency and cost reduction. Previous studies have demonstrated solo surgery with robotic camera holders to be cost beneficial [3,4,7,[15][16][17]19]. Stott et al demonstrated that the use of the Freehand camera holder was economically viable when performing laparoscopic liver resections.…”

Background Robotic camera steering systems have been developed to facilitate endoscopic surgery. In this study, a randomized controlled trial was conducted to compare conventional human camera control with the AutoLap™ robotic camera holder in terms of efficiency and user experience when performing routine laparoscopic procedures. Novelty of this system relates to the steering method, which is image based. Methods Patients undergoing an elective laparoscopic hemicolectomy, sigmoid resection, fundoplication and cholecystectomy between September 2016 and January 2018 were included. Stratified block randomization was used for group allocation. The primary aim of this study was to compare the efficiency of robotic and human camera control, measured with surgical team size and total operating time. Secondary outcome parameters were number of cleaning moments of the laparoscope and the post-study system usability questionnaire. Results A total of 100 patients were randomized to have robotic (50) versus human (50) camera control. Baseline characteristics did not differ significantly between groups. In the robotic group, 49/50 (98%) of procedures were carried out without human camera control, reducing the surgical team size from four to three individuals. The median total operative time (60.0 versus 53.0 min, robotic vs. control) was not significantly different, p = 0.122. The questionnaire showed a positive user satisfaction and easy control of the robotic camera holder. Conclusion Image-based robotic camera control can reduce surgical team size and does not result in significant difference in operative time compared to human camera control. Moreover, robotic image-guided camera control was associated with positive user experience.

“…Bhayani et al [5] and Tanagho et al [6] reported human test results that found that a 3D visualization system makes it easier to perform a standardized laparoscopic task than using a conventional 2D visualization system. Recently, several commercial 3D laparoscopy products have been on the markets and quite a few test results have been reported comparing the effectiveness of 3D versus 2D laparoscopic surgeries [7][8][9][10][11][12]. Some of these systems are robot-assisted [9,13].…”

While some wide-FoV endoscopes can reach 100-170 • FoV, they are prone to undesirable distortion [14], and may require image processing techniques to remove the distortion before the video footage can be used.…”

Large-Field-of-View Visualization with Small Blind Spots Utilizing Tilted Micro-Camera Array for Laparoscopic Surgery

Existing laparoscopic surgery systems use a single laparoscope to visualize the surgical area with a limited field of view (FoV), necessitating maneuvering the laparoscope to search a target region. In some cases, the laparoscope needs to be moved from one surgical port to another one to detect target organs. These maneuvers would cause longer surgical time and degrade the efficiency of operation. We hypothesize that if an array of cameras can be deployed to provide a stitched video with an expanded FoV and small blind spots, the time required to perform multiple tasks at different sites can be significantly reduced. We developed a micro-camera array that can enlarge the FoV and reduce blind spots between the cameras by optimizing the angle of cameras. The video stream of this micro-camera array was designed to be processed in real-time to provide a stitched video with the expanded FoV. We mounted this micro-camera array to a Fundamentals of Laparoscopic Surgery (FLS) laparoscopic trainer box and designed an experiment to validate the hypothesis above. Surgeons, residents, and a medical student were recruited to perform a modified bean drop task, and the completion time was compared against that measured using a traditional single-camera laparoscope. It was observed that utilizing the micro-camera array, the completion time of the modified bean drop task was 203 ± 55 s while using the laparoscope, the completion time was 245 ± 114 s, with a p-value of 0.00097. It is also observed that the benefit of using an FoV-expanded camera array does not diminish for subjects who are more experienced. This test provides convincing evidence and validates the hypothesis that expanded FoV with small blind spots can reduce the operation time for laparoscopic surgical tasks.

BACKGROUND: The 3D laparoscopy systems and robotic systems have been introduced into clinical practice for a few years. But the comparison of robotic and 3D laparoscopic gynecologic surgery is still needed.OBJECTIVE: To retrospectively compare the learning curves of robotic and 3D laparoscopic hysterectomy and pelvic lymphadenectomy in cervical cancer.STUDY DESIGN: The operational duration, blood loss, peritoneal drainage of first 24 hours after operation, total hospitalization days, hospitalization days after operation, lymph nodes collected, learning curves and cost of robotic and 3D laparoscopic hysterectomy and pelvic lymphadenectomy in cervical cancer performed by one experienced surgeon were studied.RESULTS: There was one surgeon who performed 37 cases of robotic and 24 cases of 3D laparoscopic hysterectomy and pelvic lymphadenectomy, and the turning point of learning curves was case 13th and case 10th. The differences of duration of operation, blood loss, peritoneal drainage of first 24 hours after operation, total hospitalization days, hospitalization days after operation, lymph nodes collected and perioperative complications were not statistically significant. But the cost of each robotic operation was higher than 3D operation.CONCLUSIONS: The turning point of the learning curve of 3D laparoscopic hysterectomy and pelvic lymphadenectomy is earlier than that of robotic sugery in patients with cervical cancer, and there is no obvious benefit from robotic surgery than 3D surgery in the terms of short-term medical index and hospitalization cost.
