The Japanese Institute for material research (NIMS) showed a video of ultra micro machining technology. They can engrave words on the mouth of mites. The font length is less than 2 microns, smaller than E. coli. This technology can be used in the development of electronic components and the processing of nano materials.

Kono production Institute: it can produce 0.03mm surgical needle

How thin can the surgical needle be - 0.03mm in diameter and 0.8mm in length. The suture on the surgical needle is too thin to be seen by the naked eye, Precision dispensing needlewith a diameter of only 0.012mm.

The application of this 0.03mm ultra-fine surgical needle in clinic has brought revolutionary changes to the field of regenerative transplantation, enabling previously difficult operations, such as the suture of blood vessels, lymphatic vessels and nerves below 0.5mm, and great achievements have been made in the regeneration of severed fingers in infants.

There are many difficulties in the development of 0.03mm diameter surgical needle. The material used for the surgical needle is special stainless steel. In the whole production process, the stainless steel needs to be stretched and cut, and the top needs to be sharpened, bent, ground and sharpened. However, the surgical needle is so small that although it is made of metal material, it should be made as light as cotton fiber and as light as hairspring. The whole processing process requires skilled employees to complete it manually under the microscope, and the required special tools and instruments are independently developed by the employees of Kono production Institute.

The headquarters and plant of Kono production office are located in Kawaguchi, Chiba Prefecture, on the outskirts of Tokyo. The company has developed the world's smallest microsurgical needle for suturing micro blood vessels and nerves. Precision dispensing needle Now it is famous all over the world with the trademark of "crownjun".
