New Maestro AR™ 3D augmented reality brings procedure-specific content to robotic surgery simulation training for Gynecology
Hysterectomy module debuts at AAGL, November 18-20, 2014
Mimic Technologies, Inc announces the launch of the Maestro AR Hysterectomy, a new augmented reality software module exclusively available on their dV-Trainer® robotic surgery simulator. Maestro AR is the first robotic surgery simulation technology that allows trainees to manipulate 3D virtual robotic instruments as a way to interact with 3D video footage of an actual surgical case.
This full procedure simulation was developed in collaboration with Dr. Arnold Advincula, president-elect of AAGL (American Association of Gynecologic Laparoscopists) and the Vice Chair of Women’s Health and Chief of Gynecologic Surgery at Columbia University Medical Center. Using 3D augmented video, Dr. Advincula guides trainees through each step of a robot assisted total laparoscopic hysterectomy (RATLH).
At each critical juncture of the procedure, trainees experience both cognitive learning and robotic surgery skills development through identification of anatomical structures and surgical landmarks, simulated tissue retractions, predicting dissection planes, answering multiple choice questions, and completing virtual reality skills exercises. These embedded virtual reality tasks, such as vaginal cuff closure, emphasize hand-eye motor skills critical to proficient surgical technique. For each step in the procedure, comprehensive metrics are gathered and reported, allowing trainees to objectively track their progress at learning the procedure and becoming proficient with required robotic surgery skills.
Maestro AR for Hysterectomy divides the complete RATLH procedure into the following steps:
1. Pelvic Survey
2. Desiccation and Transection of Fallopian Tube and Utero-Ovarian Ligament
3. Desiccation and Transection of Round Ligament
4. Incision and Separation of Broad Ligament
5. Skeletonization and Desiccation of Uterine Arteries and Vasculature
6. Creation of the Vesicouterine Reflection and Adhesiolysis
7. Transection of Uterine Vasculature
9. Vaginal Cuff closure
“By augmenting real surgical video with interactive virtual content, we are able to deliver realism on a whole new level,” said Jeff Berkley, PhD, CEO, Mimic Technologies, Inc. “Our process for generating augmented reality is also extremely efficient and we expect to generate a large volume of content over the next few years that will allow trainees to walk through a wide variety of surgical scenarios as presented by world leading educators. We feel this will expose surgeons to a tremendous variety of surgical scenarios that would not normally be encountered under a normal case load.”
Maestro AR is available exclusively on the Mimic dV-Trainer as a multi-specialty package, that includes Hysterectomy and Partial Nephrectomy, (lead by Dr. Inderbir Gill of USC). Prostatectomy and Lower Colon Resection will be added to the package within the next half year.
Maestro AR for Hysterectomy will be demonstrated at the Mimic Technologies booth (#330) during the Global Congress on Minimally Invasive Gynecology (AAGL) in Vancouver, British Columbia, Canada, on November 18-20, 2014. Mimic’s Maestro Hysterectomy will also be featured in an AAGL class (ROBO Course 603) to be held on Monday the 17th, which will be proctored by Dr. Peter Lim, Dr. John Lenihan, Dr. Martin Martino, Todd Larson, RN, MS, CNOR, Dr. Gerald Harkins, Dr. Michelle Nisolle, and Dr. Fatih Sendag.

The following blog post is a transcript of a speech Andrew J. Hung, MD (Director, Surgical Simulation & Education at USC Institute of Urology) gave during this year’s American Urological Association Annual Meeting in Orlando, Florida.
“Existing robotic virtual reality simulators have been focused on basic surgical skills. This has been a very appropriate entry point for surgeons who want to adopt robotic surgery into their practice. Procedure specific simulation is the next frontier.
In developing Procedure-Specific Simulations we have learned the following:
First, the collaboration between the surgeon and the software developer is absolutely critical. A surgeon brings to the table an intricate understanding of the anatomy as well as the procedure. The software developer brings engineering, and very specific technical capabilities, such as the 3D artist who brings our ideas into a 3D environment that’s interactive and engaging.
Second, our whole process starts with the storyboard. In our case, the robotic Partial Nephrectomy scripted from beginning to end, skin-to-skin, not leaving out a single detail. And, we record the operating room procedure. The High Definition Stereo 3D is very sophisticated recording device capable of recording the procedure with the absolute highest graphic definition.
Third, we then take the whole procedure, edit it, introduce anatomy, and ask users to point out main parts, as a baseline test, before they are allowed to move on to the next step in the operation. The procedure step leads to another cognitive type question. We ask users ‘what is the next step coming up?’ because it is important to know what to anticipate in the surgeon’s mind.
Finally, because this is now called ‘Procedure-Specific,’ we’re teaching advanced skills such as tissue retraction. We ask the surgeon, ‘Where do you grab the tissue?’ and ‘which direction do you pull it?’ and ‘with what amount of force should it be pulled?’ The intent is to create tissue manipulation that appears to be real.
In the past, procedure simulation was designed by engineers and then validated in retrospect by surgeons. But now we have flipped this process around. Now, during design development, the surgeons and engineers have to collaborate and really test their user studies. We invited faculty, expert surgeons, novice surgeons, and we’ve had them form the basic validation steps. We ask the experts, ‘is this realistic? Is this going to be a useful training tool?’ And, importantly, we compare and look in very close detail at novice performance versus expert performance because we want to see that there is an ability to distinguish between the two.
We not only look at which questions had a good difference between a novice user and an expert user, but actually focused on the questions that failed to meet current validation. And we looked at the very visual questions or exercises, and thought about how we could improve this particular question. As a result, we now have the ability to test augmented reality experiences, and this is where more and more procedure specific simulation is going.
The emphasis here is that during development, validation begins. The more advanced levels of validation, for example being able to bring or correlate the performance on this platform and real tissue, happens immediately as part of the development process. The next few steps that we want to take include integrating global assessment; sophisticated assessment into a procedure specific environment; and, full virtual reality integration.
Today everybody wants to manipulate that tissue. They want it to be real. And finally, the ultimate goal of what we do, and I think all of the folks at simulation want to do, is go beyond Procedure-Specific and into Patient-Specific rehearsal.”
New Maestro AR™ 3D augmented reality brings procedure-specific content to robotic surgery simulation training
Partial Nephrectomy module debuts at AUA, May 17-20, 2014
Mimic Technologies announces the launch of Maestro AR, a new augmented reality software module exclusively available on the dV-Trainer® robotic surgery simulator. Maestro AR is the first robotic surgery simulation technology that provides 3D virtual instruments for interaction with anatomy in a 3D video environment.
Maestro AR is available as a multi-specialty package, including Partial Nephrectomy (available now) with Hysterectomy, Prostatectomy and General Surgery modules in development for future delivery. Maestro AR for Partial Nephrectomy will be demonstrated at the Mimic Technologies booth (#917) during the American Urological Association (AUA) annual meeting, May 17 – 20, 2014, Orlando, FL.
Maestro AR for Partial Nephrectomy (partial removal of a kidney) was developed in collaboration with Inderbir S. Gill, MD (Chairman and Professor of the Catherine and Joseph Aresty Department of Urology, Founding Executive Director of the USC Institute of Urology and Associate Dean for Clinical Innovation, Keck School of Medicine of USC) and Andrew J. Hung, MD (Clinical Fellow, Advanced Robotics and Laparoscopy, Keck School of Medicine of USC).
Using the dV-Trainer, Partial Nephrectomy trainees interact with anatomical regions using virtual robotic instruments within augmented 3D video. The Partial Nephrectomy video used in the module is taken from an actual case performed by Dr. Gill.
The module also features audio narration from Dr. Gill to help guide the trainee through five procedure steps:
1) Colon mobilization
2) Kocherization of duodenum
3) Hilar dissection
4) Completion of kidney mobilization
5) Tumor excision and renorrhaphy
As they progress through the module, the trainees will identify anatomy, anticipate tissue retractions, predict regions for dissection and refine surgical skills. Partial Nephrectomy includes an embedded virtual reality renorrhaphy skills exercise designed to match the needle pattern used in this procedure.
“Mimic is proud to help fulfill demand that has built up for truly meaningful, procedure-specific content,” said Jeff Berkley, PhD, CEO, Mimic Technologies, Inc. “Our vision is to provide an exceptional training support option across multiple specialties that promotes skill development and basic familiarity with a procedure. We’re pleased that early feedback on Partial Nephrectomy suggests that Maestro AR is exceeding expectations through its unique combination of 3D instruments and augmented video.”

New component for the dV-Trainer® facilitates better teamwork between the console-side surgeon and first assistant
Mimic Technologies Inc. debuts the new Xperience Team Trainer robotic surgery simulator at the 14th annual International Meeting on Simulation in Healthcare (IMSH), January 25-29, 2014, San Francisco.
The Xperience Team Trainer is the first system exclusively designed to help the robotic surgeon’s first assistant gain experience and refine skills in a simulation environment. The new simulator functions as a complementary hardware unit for the dV-Trainer® simulator, featuring two movable laparoscopic tool ports for use by the first assistant. This enables the first assistant and console surgeon to safely train together outside of the OR.
Within the robotic surgical environment, cooperation between the console-side surgeon and first assistant is critical for efficient, effective performance. A high level of teamwork requires precise verbal communication and the ability to anticipate and react to one another’s movements during common procedural tasks.
“As the saying goes, ‘Separation is in the preparation,’” said Jeff Berkley, CEO and founder, Mimic Technologies Inc. “The first assistant’s role in influencing procedures is crucial, and perhaps underappreciated. Giving the console-side surgeon and the first assistant the chance to train together should be a tremendous asset for institutions looking to maximize patient safety and overall efficiency in robotics.”
Many of the most effective basic skills exercises on the dV-Trainer have been modified to accommodate the first assistant. These exercises build teamwork and synchronization for common maneuvers such as needle passing, tissue retraction and clip application.
“The Xperience Team Trainer should benefit institutions looking to maximize preparedness of their robotic surgery teams,” said Dr. John Lenihan, Medical Director of Robotics & Minimally Invasive Surgery, MultiCare Health Systems (Tacoma WA), Assistant Professor of OB-GYN, University of Washington School of Medicine (Seattle WA). “The new team exercises are an innovative method to help the first assistant refine their working relationship with the console-side surgeon.”
The Xperience Team Trainer leverages Mimic’s unique MScore™ evaluation system, which factors in comprehensive metrics and experienced surgeon data. MScore allows options for scoring the surgeon’s and first assistant’s performance on exercises separately, as well as for combined proficiency.
