The new light 3D laparoscopy without robotics

From being safer to more cost effective, read on to know about 3D laparoscopy – a new technique for uterus associated surgeries

3D laparoscopy is safe, creates fewer complications, is cost-effective, reduces surgery time and even the number of days the patient needs to spend in the hospital post surgery. It also gives the surgeon, performing an invasive procedure, a far better field of vision, thus improving the precision and accuracy of the surgery.

How to produce 3D surgical videos

 After performing over 25,000 laparoscopic surgeries, laparoscopic surgeon Dr Prakash Trivedi hails 3D laparoscopy as a beneficial advancement in the field of surgery. It could be a boon, for patients who have had a previous C-section, have fibroids or are high risk patients suffering from obesity, diabetes, blood pressure.

Dr Trivedi successfully performed 3D laparoscopic surgery on two patients at the Total Women’s Health Care Center, Mumbai. Parineeta Seth, 40 had been suffering from menstrual migraine, cramps, vomiting, and nausea for over a year and was mistakenly diagnosed as suffering from fibroids, when she actually had adenomysis and had to remove her uterus. “I was really worried about it but the 3D laparoscopy technique made it so simple. My sister, who underwent a hysterectomy, took a month to recover but just a week later, I don’t have any pain or discomfort and am already at work,” she says. Dr Trivedi adds, “Its just like doing an open surgery, but with the benefits of minimal invasion. Even suturing with 3D laparoscopy is so clear and simple.”

Olympus Introduces the World's Only Articulating HD 3D Laparoscopic Surgical Video System

Technology Improves Speed, Accuracy and Precision of Surgical Procedures When Compared with 2D Surgical Systems.

The Olympus Articulating HD 3D Laparoscopic Surgical Video System delivers value to surgeons and patients by reducing surgical errors and improving the speed, accuracy and precision of surgical tasks such as dissection, grasping and suturing when compared with traditional 2D surgical systems, based on internal Olympus testing conducted using a simulated surgical model. This is accomplished by restoring natural 3D vision and depth perception when performing laparoscopic procedures and is independent of a surgeon's skill level.

"The Olympus HD 3D system is ideal for suturing, accurately identifying tissue planes and other precision surgical tasks that are required in my laparoscopic surgical cases," said Dr. Marcos Michellotti, Assistant Professor of Surgery at Loma Linda University Health System in Loma Linda, California. "In addition, the articulating design enables me to obtain the critical view of anatomical structures in HD 3D without losing the important visual horizon. This is not possible with traditional fixed angle laparoscopes."

Another significant advantage of the new Olympus HD 3D video platform is its availability as a module that can be easily added to an existing Olympus EVIS EXERA III Universal Imaging System. The modular design reduces the investment necessary to add 3D capability, and allows the surgeon to choose either 2D or 3D visualization from the surgical field. This helps to reduce capital investments and simplify asset management and training.                            

"The Olympus HD 3D System brings value to those surgeons that need the precision, resolution, and depth perception of 3D without the substantial capital investment and annual maintenance expenses associated with alternatives such as robotic technology," said Luke Calcraft, President of the Medical Systems Group at Olympus Corporation of the Americas. "We are leading the way with new innovations to help our customers realize the clinical efficacy and cost effectiveness required under Accountable Care."

Olympus is a pioneer of minimally invasive surgery (Laparoscopy), a modern technique in which an operation in the abdomen is performed through small incisions as compared to larger incisions needed in traditional surgical procedures. This surgical approach addresses the key requirements of Healthcare Reform:

Increased Quality of Care – Minimally invasive surgery provides better clinical outcomes than traditional "open" surgery.
Decreased Costs – Numerous industry and clinical studies have demonstrated that minimally invasive surgery provides significant cost savings when compared to a robotic surgical approach.*
Enhanced Patient Satisfaction – Minimally invasive surgery provides less scarring, shorter hospital stays and faster recovery than traditional "open" surgery.

A High-Resolution Endoscope as thin as a Human hair

Engineers at Stanford have developed a prototype single-fiber endoscope that improves the resolution of these much-sought-after instruments fourfold over existing designs. The advance could lead to an era of needle-thin, minimally invasive endoscopes able to view features out of reach of today’s instruments.

Engineers at Stanford have demonstrated a high-resolution endoscope that is as thin as a human hair with a resolution four times better than previous devices of similar design. The so-called micro-endoscope is a significant step forward in high-resolution, minimally invasive bio-imaging with potential applications in research and clinical practice. Micro-endoscopy could enable new methods in diverse fields ranging from study of the brain to early cancer detection.The new endoscope was developed by a team under the direction of Joseph Kahn, professor of electrical engineering at the Stanford School of Engineering. The results were published recently in the journal Optics Express and showcased in the Optical Society of America’s Spotlight on Optics.

Their prototype can resolve objects about 2.5 microns in size, and a resolution of 0.3 microns is easily within reach. A micron is one thousandth of a millimeter. By comparison, today’s high-resolution endoscopes can resolve objects only to about 10 microns. The naked eye can see objects down to about 125 microns.

3D technology useful to even experienced surgeons

A new study has shown that even experienced surgeons stand to benefit from 3D technology.

While physicians have largely ignored 3D technology until now, it appears to be getting a second chance, according to a new study of the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute HHI and Klinikum rechts der Isar university hospital in Munich.

Thanks in particular to improved 3D-glasses and screens, practical tests have recently shown that 3D systems used in medical technology have benefits that were once believed to be purely theoretical.

Researchers showed that even experienced physicians could benefit from the latest generation of 3D devices, after some 50 surgeons responded positively to 3D systems both with and without glasses.

“While the technology still requires some fine-tuning, technology that does without the need to wear special glasses will increase the popularity of 3D systems in operating rooms. In the past, surgeons were hesitant to use the technology precisely because of the glasses,” said Dr Ulrich Leiner, head of the Interactive Media – Human Factors department at HHI.

The study was conducted as a result of current developments in 3D screen technology which have seen 4K models for medical applications that offer quad HD resolution become readily available.

“The next step is ultra-high definition with 8K. This will mark a 16-fold improvement on the resolution of currently available full-HD images,” said Michael Witte of HHI in explaining current trends.

Witte is convinced that 3D without glasses will contribute to a lasting breakthrough.

“This is why the researchers thought it was high time to carry out a scientific test that would assess whether 3D technology has reached the level of maturity required of sensitive hospital applications,” he said.

Surgeons participating in the test tried a total of four different screen systems: 2D, 3D with and without glasses, and a mirror apparatus that served as the ideal 3D model.

Images were delivered by endoscopic cameras that the doctors used during a simulated routine surgical procedure in which physicians sewed up a wound with ten stitches using a needle and thread in a model abdominal cavity.

Just as would be the case in a minimally invasive surgical procedure, the surgeons did not have a direct view of their hands, and thus depended on the screen.

“The results were astonishing: with the glasses-based 3D system the procedure was more than 15 per cent shorter, and precision increased considerably. Hand movements were more targeted than with the 2D model.

“As far as I know, we have not observed this effect among our experienced surgeons in the past,” said Professor Hubertus Feußner in describing the test winner.

The surgeon, who has worked at Klinikum rechts der Isar for over 30 years, has conducted several thousand operations.

“In the past, it was the most experienced physicians in particular who were very skeptical of 3D technology. And this was not only because it hardly offered any tangible benefits. Many physicians felt uncomfortable looking at the screens, and preferred to rely on their experience as a result,” said PD Dr Silvano Reiser, Feußner’s colleague.

The model without glasses also made a positive impression – test participants considered its quality as comparable to 2D.

“Unfortunately, the system we developed was unable to take the first place ranking. But the first hard practical medical test showed great promise, as we were able to work on the fundamental eye-tracking technology.

“This is where, through eye-tracking, cameras follow both eyes, and each eye sees a separate image. This creates a 3D effect without glasses,” Leiner said.

Laparoscopic Surgery with 3D Visualization at Keck Medical Center of USC

Anthony Senagore, chief of colorectal surgery at Keck Hospital of USC, leads the first team on the West Coast to implement a novel 3D visualization tool designed by Viking Systems. The use of a 3D camera and special glasses brings depth perception to surgeons who would otherwise have to compensate for a flat view of the organs on which they're operating.

"We've been performing advanced laparoscopic procedures for many years, and many of us have learned how to accommodate a two-dimensional picture," Senagore said, "but his is really the first time we've been able to replicate the way we normally see the operative field. It's enabled us to expedite the procedures and should improve accuracy and safety."

Senagore feels the technology will also help trainees acquire advanced surgical skills more quickly, and is eager to discover additional benefits.

"This is our first attempt to explore this technology," Senagore noted. "Our initial experience has been very good."

3D camera for brain surgery a big leap forward

The Toronto doctor who pioneered what has become an international standard in neurosurgery is once again breaking new ground, becoming the first surgeon in Canada to use a 3D camera to remove a brain tumour.

Dr. Michael Cusimano made headlines 17 years ago when he became the first neurosurgeon in the world to remove tumours by endoscopic surgery, a minimally invasive procedure that involves sending a video lens along with instruments through both nostrils and into the brain.

The 3D tool he ultimately developed helps surgeons precisely manoeuvre their instruments in a tiny space. The better view enables surgeons to remove more of a tumour with reduced risk of error.

Back in the operating room, with the 3D endoscope buried about 10 centimetres in his patient’s nose and brain, Cusimano marvelled at the image on the screen.

It was as though his own eyes were in the patient’s brain, he says, noting the 3D view allowed him to more accurately and quickly resect the patient’s tumour.

After his first run with the 3D endoscope, Cusimano gave the new technology two thumbs up.

“We’re excited by it. It’s a natural evolution to surgery,” says the doctor, who also teaches medical students at the University of Toronto.

Health Canada approved the 3D endoscope this past spring. In the United States, the Food and Drug Administration approved it more than a year and a half ago and now about a dozen hospitals there use it. It’s widely employed in Italy, and hospitals in other European countries as well as Israel also use it.

Panasonic introduces medical-grade 3D monitor for surgery

SECAUCUS, NJ – Panasonic, a provider of professional healthcare display and monitor solutions, today announced a new 3D medical-grade 32” class monitor.

The new monitor, the EJ-MDA32U-K, is fully compliant with medical equipment standards, delivers 2D and 3D image quality and can display multiple images from various sources at once, according to Panasonic officials.


These combined features, paired with Panasonic’s renowned reliability, make the new monitor ideal for use in the surgical bubble, they said in a press release.

“To improve patient outcomes, there is an ever increasing reliance on technology in the surgical suite,” said Scott Thie, director of Healthcare, Panasonic System Communications Company of North America. “Although this technology has many benefits, it can also create a cluttered environment."

The EJ-MDA32U-K helps to improve the surgical experience by having a large screen, HD image that can be clearly viewed by all clinicians, while also providing flexibility that helps to reduce clutter, according to Thie. “By allowing up to three images to be displayed on the screen at once – from multiple input sources – and by delivering high quality 3D and 2D HD images, we offer a single device that addresses multiple needs in the surgical suite,” he said.
