Magic implants help patients recover from severely damaged limbs

A team of scientists led by John Heckock, a bioengineering professor at the University of Sheffield in the United Kingdom, designed soluble implants to help patients recover from severely damaged limbs.

According to foreign media reports, scientists have recently achieved major medical breakthroughs. The magic implants they designed can help patients recover from severely damaged limbs. The research report was published in the latest edition of the "Biofabrication" magazine.

British scientists and German engineers designed a dissolvable implant that can help the nerves reconnect and restore severely injured arm and leg motor function and perception. Scientists used laser technology to make some nerve guidance conduits. Neural induction tubes are made of a biodegradable plastic that guides nerve fiber re-growth through individual pathways to help restore limb awareness. Once the nerves are completely regenerated and reconnected, the device will dissolve automatically.

The researchers explained that surgeons are already better at reconnecting bones and muscles, but connecting nerves has always been a problem. John Haycock, a professor of bioengineering at the University of Sheffield in the United Kingdom, said: "The nerves in the arms or legs can be regenerated and are different from the nerves in the spinal cord. However, the damaged nerves need assistance to regenerate. We are designing stent implants that can heal wounded areas and provide a series of physical and chemical substances that stimulate this regeneration.

Implantation tests have shown that nerves grow naturally through trough-like structures. The researchers pointed out that they hope that this technology will be widely applied to injured peripheral nerves. The co-author of the study, Dr Frederik Claeyssens from the Department of Materials Science and Engineering at the University of Sheffield, said: "The nerves are not just like a long cable, they are It consists of many small cables, similar to how a wire is constructed.Using our new technology, we can make a catheter so that nerve fibers can form a similar structure and become an undamaged nerve. The induction tube can help treat spinal cord injury.” He added: “The most exciting part of this research work is that we not only designed a nerve support for nerve growth, we also developed a nerve A new method that is easy to regenerate. This technique can make a huge difference in a patient with severe nerve damage.” (Shangli)

Infrared Sauna Room

An infrared sauna room is a type of sauna that uses infrared heaters to emit radiant heat, which is then absorbed by the body. Unlike traditional saunas that heat the air around you, infrared saunas directly heat your body, allowing for a more efficient and comfortable experience.

The infrared heaters in the sauna emit infrared radiation, which is the same type of heat that is produced by the sun. This heat penetrates deep into the body, promoting relaxation, detoxification, and various health benefits. The temperature in an infrared sauna room is typically lower than in a traditional sauna, making it more tolerable for longer sessions.


Apart from the physical benefits, sauna rooms are often used for relaxation and stress relief. The heat and steam create a soothing environment that can help calm the mind and reduce anxiety. Sauna sessions can also promote better sleep and improve overall mood.
