Latest Patents

Kakinuma is credited with 1 patent, titled “Medical suture needle.” The invention features a cutting-blade section continuous with the needle’s body. Its tip is formed where one bottom surface and two inclined surfaces meet, with a cutting blade and ridge extending from that point. The blade section becomes thinner toward the tip.

Curved grooves are formed along the ridge on the inclined surfaces, beginning a set distance from the point. At the body-side ends of the grooves, their lower edges move away from the cutting blade toward the ridge. This geometry is intended to help reduce bending and cracking in the needle’s tip section.
