Patient-Side Robotic Surgical Platform provides high-definition 3D vision

TransEnterix engineers have developed a robotic single-site surgical platform that is mobile, provides high-definition 3D vision, and allows the surgeon to remain at the patient’s side.

Called SurgiBot, the company’s newest system is undergoing testing now, according to Todd M. Pope, president and CEO of TransEnterix.

“TransEnterix has ‘powered up’ laparoscopy to make it easier for surgeons to complete procedures in the most minimally invasive way possible,” Pope says. “SurgiBot utilizes robotic technologies and techniques to enhance strength, precision and ergonomic comfort for surgeons.”

SurgiBot is small and mobile, making it easy for hospitals to move it among operating suites. Its design allows the surgeon to stand at the operating table and remain in direct contact with the patient at all times – versus other robotic systems that require the surgeon to work separated from the patient.

Here’s how SurgiBot works: The surgeon makes a small, single incision in the patient’s abdomen – often hidden inside the belly button – and inserts the device. It opens up like an umbrella, extending articulating instrument channels, which surgeon’s hands control for strength and precision. Once expanded, SurgiBot delivers high-definition, three-dimensional visualization at the operating site, restoring depth perception lost in traditional laparoscopic procedures.

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.

The World's First 3D LASIK AND Tennessee's First 3D Cataract Surgery Performed

The new 3D image-guided, microsurgical technology improves the quality of LASIK and cataract surgeries

NASHVILLE, Tenn., July 1, 2011 /PRNewswire/ -- Dr. Ming Wang of Wang Vision Cataract & LASIK Center, Nashville, TN, became the first surgeon in the world to perform a 3D LASIK procedure, and the first in Tennessee to perform a 3D cataract surgery. The first such ground-breaking surgeries took place at Wang Vision Cataract & LASIK Center on May 27, 2011 and June 2, 2011, respectively. Both procedures utilized off-label uses of the TrueVision® 3D high-definition, real-time, stereoscopic microsurgical technology.

The world's first 3D LASIK patient was Mr. Farah Jai-Aden, a 28-year-old truck and taxi driver from Atlanta, GA. At his first post-operative visit, he could already see better than he ever had before, even with glasses or contact lenses! The state's first 3D cataract surgery patient was Mr. David Mehosky. Both Mr. Jai-Aden and Mr. Mehosky are very pleased with their new 3D vision!

"We are very excited to be the first in the world to perform the 3D LASIK procedure, and the first in Tennessee to perform a 3D cataract surgery," said Dr. Wang, who is a clinical associate professor of ophthalmology for the University of Tennessee and the director of Wang Vision Cataract & LASIK Center, Nashville, TN.


About Ming Wang, MD, PhD:

Dr. Ming Wang, a graduate of Harvard & MIT (MD, magna cum laude), is one of the few cataract and LASIK surgeons who holds a doctorate degree in laser physics.  He has introduced many new eye surgeries to Tennessee, including bladeless all-laser LASIK, wavefront technology, new Intacs to treat keratoconus, and a new generation premium lens for cataract surgery.
