Abstract
The present invention relates to a medical thread which has on one end thereof a stopper that has a polygonal cross-section, and which exhibits excellent end adhesive force and penetration resistance, and to a manufacturing method for same.
Claims13
A medical thread comprising:
- a body;
- and a stopper connected to one end of the body,
- wherein the end of the body connected to the stopper has a circular cross section,
- wherein the body is extended along the longitudinal direction,
- wherein the stopper has a polygonal cross section at the part connected to the body,
- wherein three or more of the distances from the center of gravity of the polygonal cross section of the stopper to each vertex of the stopper are 2 times to 15 times the radius of the circular cross section of the end of the body, and
- wherein the penetration resistance of the stopper is 0.2 kgf or higher.
4 more elements
A method for manufacturing a medical thread, comprising the steps of:
- preparing a body extended along the longitudinal direction;
- heating and melting one end of the body;
- injecting the melted end of the body into a mold having a predetermined shape to form a stopper at the end of the body;
- cooling and separating the body and the stopper from the mold,
- wherein the end of the body connected to the stopper has a circular cross section,
- wherein the stopper has a polygonal cross section at the part connected to the body,
- wherein three or more of the distances from the center of gravity of the polygonal cross section of the stopper to each vertex of the stopper are 2 times to 15 times the radius of the circular cross section of the end of the body, and
- wherein the penetration resistance of the stopper is 0.2 kgf or higher.
