Brain surgeons get a practice run with simulator from Elyria-based Surgery Theater

For a number of years, pilots have used virtual reality simulators to practice critical missions before taking to the skies. Thanks to a revolutionary new virtual reality training tool developed by Elyria’s Surgical Theater, LLC, surgeons now have a way to practice brain surgery before setting foot in the operating room.

The Surgery Rehearsal Platform (SRP) simulator consists of a desk top computer, a portable laptop system, software, controllers and 3D glasses.

“Using standard CT and MRI images from any patient, the SRP generates accurate models in 3D that show the interaction between life-like tissue and surgical instruments,” explains Moty Avisar, Surgical Theater president and CEO. “The tissue responds realistically to actions taken by the surgeon, enabling pre-surgery planning and rehearsal with complete accuracy.”

Beyond practicing on standard CT and MRI images, surgeons can also use unique images taken of the patient who will be undergoing surgery.

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.

3-D imaging lets brain surgeons rehearse risky procedures

Using CT and MRI scans, software builds up a 3-D image of the brain.

A surgeon probes a patient's brain and sees her target: a swelling on the side of a blood vessel, like a blister on a tire where the rubber has worn off. It's an aneurysm. She uses tiny clips to cut it off from the blood vessel. But there's a problem: an unseen defect causes the aneurysm to burst, resulting in a massive stroke. But there's no problem — she can try again because it was all done in a simulator.

In the next few months, University Hospital Case Medical Center in Cleveland and UCLA will be testing a 3-D imaging system that, coupled with a tool that gives tactile feedback, will allow doctors to rehearse high-risk brain surgery. The system will be tested on virtual brain aneurysms, comparing the outcomes with real surgeries that were done without it.
