News reports drone on constantly these days with more and more negative information. I don’t get the same kind of vibe when I talk to design engineers every day for my writing about materials and fastening technology for Design News. Most incredible to me are reports on advances in medical technology by American inventors and engineers. The most recent was an interview I had with Dave Danitz, the vice president of research and development at Novare Surgical Systems In California, which recently developed and brought to market an instrument called RealHand that allows laparoscopic surgery through a single port—and even through natural orifice such as a mouth. The result is a dramatic reduction in the risk of infection.
Invented by Danitz, the RealHand is a fully mechanical instrument up to 45 centimeters in length in which jaws at the distal end move inside the human body in reaction to movements of a surgeon’s hands on a handle. Small articulating links connect the jaws to the shaft and the handle to the shaft, which can vary in length from 24 to 45 centimeters. There are no electronics in the device.
Although introduced just six months ago, a number approaching 100 surgeons use the tool.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
