Bicomponent variable chamfer tooth self-locking suture

The utility model relates to a bicomponent variable chamfer tooth self-locking suture. The bicomponent variable chamfer tooth self-locking suture comprises a main body and chamfer tooth structures and is characterized in that the main body and the chamfer tooth structures jointly form a bicomponent skin-core type structure or a bicomponent parallel type structure, wherein the main body is of a bicomponent structure, and the chamfer tooth structures are of a single-component structure and are distributed along the length direction of the body in a unidirectional or bidirectional mode. The bicomponent variable chamfer tooth self-locking suture has the advantages of being simple in design, easy to operate, capable of achieving continuous processing and applicable to surgical operations such as minimally-invasive cosmetic surgeries, laparoscope suturing and tendon suturing, convenient and fast in operation process without any knotting, good in holding effects on different tissues and capable of meeting the streng
