Medical suture having micro cogs on surface and method of manufacturing the same

摘要

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.

主权项

1. A method of manufacturing a medical suture comprising:
(1) 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 at a temperature condition from a point less than a melting point of the raw material of the suture to a point more than a glass transition temperature at a pressure condition from 10 kgf/cm2 to 200 kgf/cm2 in a heat-press solid-phase forming method; and (2) producing a suture with twist maintained by heating the suture preform and applying a tensile force and a rotational force to the suture preform in a vacuum state where the temperature condition from a point less than the melting point of the raw material of the suture to a point more than the glass transition temperature is maintained.
