Japan developed with hair of medical needles

Japan Toyo University Engineering Department of Yoshida goodness a research team led by Professor uses human hair successfully manufactures medical painless needles. Compared with metal needles, hair pins with toughness and not easily broken. The patent-pending technology.

Toyo University development of hair there are two types of needles.

One is through observation of neuronal activities of electrode electrode needles, and the other is artificial dialysis remain in the body of a hollow needle. Both the needle manufacture.

The research team developed the needle is in the hair on the plating on metal and resin membrane, can be used as an electrode needle; in hair internal diameter of 1 mm open empty hole, can also be used as transmission fluid infusion needle.

Using a unique laser processing technology, researchers in the organization is not compromised by processing the needle. The diameter of a human hair is about 70 microns to 120 Micron, without pain, also suitable for capturing moving objects and difficult to damage the blood vessel. In addition, the needles used can also burn treatment, never appears medical waste.

Allegedly, the electrode needle is expected to enter the market after two years, hollow needle is expected this year to conquer 1 mm insulating technology.

But the two hair-pin development is still a lot of problems, such as electrode needle pull the needle from the body, the surface of gold may be split into the human body, not suitable for repeated use; hollow needle in chlorine solvent treatment needles, difficult to maintain the stability of 1 mm diameter.

The research team is working on the hair of the composition, analysis of individual differences, while continuing to push the technology to deepen the study with a view to practical use as soon as possible.
