A surgical scalpel for surgeons

Russian inventors have invented new surgical knives - more durable, sharper and longer worn than existing models of scalpel tools. Using a new knife for surgery will cause less injury, but the wound heal more quickly. "Eternal Dao" is the name that Russian experts use to invent new know-how. Such a tool has a service life that is 7 to 10 times longer than a conventional scalpel.

The new porcelain surgical knife is used in the most complex surgery, whether visceral, skin or tendons and ligaments. It will also be used in microsurgery. The whole secret is in high precision. The sharp knife is much sharper than a metal knife. Its cutting edge thickness is only 0.1 - 0.2 microns while the metal blade is 0.7 microns. Test results show that the new scalp after a new scalp 2-3 times. This is understandable as the tissues are less vulnerable, even in the most complicated surgical interventions.

The new Zirconium dioxide-based, hard-wearing ceramic ceramics with aluminum oxide and special additives can be used permanently, experts say. Zirconium dioxide is currently one of the most popular materials in the electronics, optical fiber and precision engineering, primarily due to its friction-resistant, corrosion-resistant and heat-resistant properties. It is no surprise that the new knives are highly durable. The life span of a non-sharpened surgical knife now outperforms metal tools by nearly ten times.

It is especially important that the new product possesses inertia for any active medium, including biological inertia.

Porcelain chisels are manufactured in two types - a monolithic fixed blade and a multi-blade knife, which can change the tongues with different angles. New products in the health sector have been successfully tested in hospitals and are protected by patent certificates.
