Publication number: 20200323525Abstract: The surgical suture needle includes a tip section, a main body, and a base end portion. The tip section is colored in a color different from a color of other portions. The tip section has a tapered shape, and a length of the tip section is 10% of a whole length of the suture needle. When the suture needle penetrating the biological object is pulled out by grasping with a needle holder, grasping the tip section of the suture needle easily breaks the suture needle. Therefore, a doctor grasps a portion other than the tip section with the needle holder. The colored tip section ensures the doctor easily distinguishing the tip section from the other portions. Coloring the tip section in red, green, purple, or pink ensures avoiding erroneously grasping the tip section since the tip section is unnoticeable at a suture position where blood is attached.Type: ApplicationFiled: March 29, 2017Publication date: October 15, 2020Applicant: SMR CO., LTD.Inventor: Keisuke MATSUMOTO
