Israeli Mazor Robotics has unveiled its new Renaissance spinal robotic surgical guidance system.  The device takes advantage of the same technology inside Mazor’s SpineAssist , but improves on usability through new hardware and software.  The Renaissance system has already received both FDA clearance and EU’s CE Mark of approval.

From Mazor Robotics:

3gjsj Mazors New Renaissance Robotic Spinal Surgery System

Renaissance features an entirely new design and human interface, as well as next-generation hardware and software technologies. These are designed to increase surgical safety as well as extend the range of clinical applications, enabling osteotomies, transfacet and translaminar-facet implant placements, in addition to procedures such as spinal fusions and scoliosis corrections currently performed with Mazor Robotics’ technology. Renaissance also serves as a platform that will support future clinical applications, such as robotic-guided cranial surgeries.

Continuing Mazor Robotics’ commitment to safety, Renaissance reduces radiation protocols for preoperative CTs by up to 50%, which means patients will be exposed to significantly less radiation. The Company also collaborated with surgeons on developing surgical tools and technological enhancements for Renaissance that further reduce the potential for human error.
Wide Range of Clinical Applications

Hardware and software tools enable a variety of spine procedures

  • Open, MIS, and percutaneous posterior thoracolumbar approaches
  • Scoliosis and other complex spinal deformities
  • Pedicle screws – short and long fusions
  • Transfacet screws and translaminar-facet screws
  • Osteotomies
  • Biopsies

New Tegaderm Diamond Pattern Film Dressing

3M is building on everyone’s favorite Tegaderm line of bandages with the Tegaderm Diamond Pattern Film Dressing, a transparent new film that breathes and manages moisture well enough that the company believes may allow for fewer necessary dressing changes.  The company is rolling out the product in the US and a number of other selected countries.

According to Matt Fryxell, 3M new products marketer, “The Tegaderm™ Diamond Dressing is an ideal solution for many patients, including those who may become unexpectedly diaphoretic. Additionally, the highly breathable dressing is engineered with pressure-sensitive adhesive to conform to the skin’s irregular surface for a long, comfortable wear, even when environmental conditions have historically posed challenges for optimal dressing performance.”

MANOS Carpal Tunnel Release System Is Short and Sweet and Minimally Invasive

by Gene Ostrovsky on May 23, 2011
MANOS Carpal Tunnel Release System Is Short and Sweet and Minimally Invasive

How about a carpal tunnel surgery that can be as short as 4 minutes and requires no stitching or presence of an anesthesiologist? The people behind an interesting new device for minimally invasive CTR think the have such a technology. Developed by Dr. Bruce McCormack, a San Francisco neurosurgeon, the procedure takes advantage of the fact that you don’t have to see the nerve to know where it is. According to Dr. McCormack, who gave Medgadget a rare interview, the procedure has already been performed more than 150 times, in 4 states since its launch in November. And more centers are being lined up.

So in a nutshell, the procedure is performed through 2 small skin incisions that are placed distal and proximal to the transverse carpal ligament, under a local anesthetic. The Manos cannula is inserted under the ligament, and hooked up to a standard nerve stimulator. The characteristic movement of thenar muscles from a stimulation of a motor branch of median nerve tells the surgeon where the nerve bundle is located. Following that, the ligament can be released, when a previously blunt cannula is converted into a cutting device.

Gentag Announces Cell Phone Based Post-Operative Orthopedic Surgery Monitoring Kit

Gentag has announced the first application of their near field communication (NFC) diagnostic platform: a cell phone based post-operative orthopedic surgery monitoring kit. The kit consists of a temperature and pressure measuring chip that communicates with NFC equipped cell phones. It can monitor swelling in the surgery area or inside casts to detect compartment syndrome after hospital discharge.  It can also be used to do back pressure and bed sores monitoring. The technology is based on an ultra-linear NFC-MEMS hybrid chip with 1mm mercury (Hg) precision and 0.1 C temperature accuracy. The technology will be compatible with Google, BlackBerry, Nokia, Samsung and other brand cell phones integrating the NFC chip, and can also be bundled with cheap NFC cell phones (e.g. Gentag’s GT-601) to make low cost hospital discharge wireless monitoring kits. For now the technology is available for limited post orthopedic surgery trials, but commercial launch is expected in 2012, starting first with pressure monitoring in casts.
