Abstract
Provided are a medical suture having micro cogs on a surface thereof and a method of manufacturing the medical suture. The method of manufacturing a medical suture includes steps of: producing a suture preform where micro cogs are formed on a surface thereof by heating and pressing a raw material of a suture for surgery in an overflow mould in a heat-press solid-phase forming method; and producing a suture with twist maintained by applying a tensile force and a rotational force to the suture preform in a vacuum state where a specific temperature condition is maintained.
