Tattoos mark the spot for surgery and then disappear

Tattoos mark the spot for surgery and then disappear
Tattoos aren't just for body art. They can have medical applications, too. Doctors are using them on patients to mark an area for future treatment - particularly for non-melanoma skin cancer such as basal cell carcinoma - but the inks can cause problems. Now scientists have developed a better solution. In the journal ACS Nano, they report an ink that glows only under certain light conditions and can disappear altogether after a period of time.

Stimulator bypasses spine injury and helps patients move hands

Stimulator bypasses spine injury and helps patients move hands
Doctors at Ronald Reagan UCLA Medical Center have implanted a spinal stimulator that is showing early promise in returning hand strength and movement to a California man who broke his neck in a dirt-biking accident five years ago. Brian Gomez, 28, became one of the world's first patients to undergo surgery for the experimental device in June 2016. UCLA scientists positioned the 32-electrode stimulator below the site of Gomez's spinal-cord injury, near the C-5 vertebrae in the middle of his neck.

Device lets women do part of breast reconstruction at home

Device lets women do part of breast reconstruction at home
This might be the ultimate do-it-yourself project: Doctors are testing a device that would let women do part of their own breast reconstruction at home. It's aimed at not only making treatment more comfortable and convenient, but also giving women a sense of control—something cancer often takes away. More than 100,000 women each year in the United States have surgery to remove a cancerous breast, and many of them choose reconstruction with an implant.

‘Prototype pathway’ yields organ transplant technology

‘Prototype pathway’ yields organ transplant technology
Organ transplantation has come a long way from its early days in the mid-twentieth century. But even with major medical advances, there’s still an admittedly familiar factor at play: ice. Just prior to transplantation, an organ is reconstructed and prepared in the sterile operating room during what is known as the “backbench procedure.” As surgeons prepare the organ, it stays cooled and preserved in a hypothermic state in a basin on a bed of sterile ice.

Simulation technology leads to better surgery planning

Simulation technology leads to better surgery planning
A team of researchers led by Stanford engineers has moved a step closer to helping surgeons more safely perform a life-saving procedure for victims of brain trauma. While surgeons have long performed an operation called a decompressive craniectomy – cutting a hole in the skull to give the swelling brain space to expand – the technique requires a fair amount of guesswork on how best to proceed.

Alternative to brain surgery could control movement disorder

Alternative to brain surgery could control movement disorder
  A study published in the New England Journal of Medicine offers the most in-depth assessment yet of the safety and effectiveness of a high-tech alternative to brain surgery to treat the uncontrollable shaking caused by the most common movement disorder.

Sensor helps anaesthetists accurately guide needles

Sensor helps anaesthetists accurately guide needles
Over 13 million pain-blocking epidurals are performed every year in the United States and, although generally regarded as safe, there are complications in up to 10% of cases where the needles are inserted too far or placed in the wrong tissue. Researchers from MIT and Massachusetts General Hospital hope to improve this statistic with a new sensor that can be embedded into an epidural needle, helping anaesthetists guide the needle to the correct location.

Vibrations in tools could improve surgeons' sensitivity

Vibrations in tools could improve surgeons' sensitivity
A small vibrating device added to surgical tools could improve surgeons' sensitivity to different shapes and textures inside their patients' bodies. Engineers from Hiroshima University have designed the small vibrating device to attach to any existing hand-held surgical tool and be used instantly, without requiring extra training for doctors. During minimally invasive surgeries, surgeons rely on long, thin, metal tools to explore their patients' bodies.

Minimally traumatic and inexpensive ceramic laser scalpel

Scientists from MIPT and their colleagues have developed a compact and powerful ceramic-based laser with applications in minimally traumatic and inexpensive laser surgical scalpels, and also for cutting and engraving composite materials. The results of the study have been published in Optics Letters. Today, lasers are in consumer electronics devices, medicine, metallurgy, metrology, meteorology, and many other areas.
