Biocompatible 3-D tracking system has potential to improve robot-assisted surgery

17.02.2017

The cutting-edge biocompatible near-infrared 3D tracking system used to guide the suturing in the first smart tissue autonomous robot (STAR) surgery has the potential to improve manual and robot-assisted surgery and interventions through unobstructed 3D visibility and enhanced accuracy, according to a study published in the March 2017 issue of IEEE Transactions on Biomedical Engineering.

The study successfully demonstrates feasibility in live subjects (in-vivo) and demonstrates 3D tracking of tissue and surgical tools with millimeter accuracy in ex-vivo tests. More accurate and consistent suturing helps reduce leakage, which can improve surgical outcomes.


Smart Tissue Autonomous Robot (STAR), developed by the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children's National Health System, performed the first supervised autonomous robotic soft tissue surgery on a live subject in May 2016.

Authored by the development team from Sheikh Zayed Institute for Pediatric Surgical Innovation at Children's National Health System and funded by the National Institutes of Health, the study explains the design of the 3D tracking system with near-infrared fluorescent (NIRF) markers and, using robotic experiments, compares its tracking accuracies against standard optical tracking methods. At speeds of 1 mm/second, the team observed tracking accuracies of 1.61 mm that degraded only to 1.71 mm when the markers were covered in blood and tissue.

"A fundamental challenge in soft-tissue surgery is that target tissue moves and deforms, becomes occluded by blood or other tissue, which makes it difficult to differentiate from surrounding tissue," says Axel Krieger, Ph.D., senior author on the study and program lead for Smart Tools at the Sheikh Zayed Institute. "By enabling accurate tracking of tools and tissue in the surgical environment, this innovative work has the potential to improve many applications for manual and robot-assisted surgery."

The system is made up of small biocompatible NIRF markers with a novel fused plenoptic and near-infrared (NIR) camera tracking system, enabling 3D tracking that can overcome blood and tissue occlusion in an uncontrolled, rapidly changing surgical environment. Krieger explains that the NIR imaging has the potential to overcome occlusion problems because NIR light penetrates deeper than visual light.

"This work describes the 'super human eyes' and a bit of 'intelligence' of our STAR robotic system, making tasks such as soft tissue surgery on live subjects possible," explains Peter C. Kim, M.D., vice president and associate surgeon in chief of the Sheikh Zayed Institute.

Future work will include further integration and evaluation of the tracking system in image-guided medical interventions such as robotic surgeries.

The Sheikh Zayed Institute for Pediatric Surgical Innovation at Children's National Health System is a hub for innovation focused on making pediatric surgery more precise, less invasive and pain free. It was founded in 2010 through a $150 million gift from the Government of Abu Dhabi. By combining research and clinical work in the areas of imaging, bioengineering, pain medicine, immunology and personalized medicine, the institute's physicians and scientists are developing leading-edge knowledge, tools and procedures that will benefit children globally.

The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.

One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
