Latest Patent Applications

Yoshiharu Iwase has filed several patent applications, including a notable one titled "METHOD OF MANUFACTURING INJECTION NEEDLE." This application describes a process for creating an injection needle made from an alloy containing cobalt and molybdenum. The method involves performing a lancet cut on a pipe-like metallic material to form a blade tip and blade part. The distal end part, which includes the blade tip, is then mechanically polished and immersed in an electrolytic solution for further polishing. This process effectively removes burrs generated during mechanical polishing. The resulting injection needle boasts a low and smooth surface roughness on its inner peripheral surface, offering advantages over conventional stainless steel needles.
