Abstract
Disclosed is an an apparatus for forming cogs on a surgical thread, comprising: a bobbin having a suture thread wound thereonto; first and second tension rolls for maintaining, at regular tensions, the suture thread unwound from the bobbin; a pair of friction rolls for drawing the suture thread and allowing the suture thread to pass through so as to be discharged through an outgoing side; a tension plate operating up and down, for temporarily fixing the suture thread being discharged through the outgoing side by the friction roll; and a cog-forming knife for forming cogs by rotating and simultaneously moving forward toward the suture thread fixed by the tension plate and also obliquely moving to the left or the right so as to make oblique cuts on the surface of the suture thread.

An apparatus for forming cogs on a surgical thread, comprising:
- a bobbin (110) around which a suture thread (100) is wound;
- a first tension roll (200) and a second tension roll (210) which maintain the suture thread (100) unwound from the bobbin (110) at a constant tensile force;
- a pair of friction rolls (300) through which the suture thread (100) passes to be discharged toward an output side by being pulled;
- a push plate (330) which temporally fixes the suture thread (100) moved toward the output side by the friction rolls (300) and moves upward and downward;
- and
- a cog-forming knife (400) which simultaneously rotates and moves forward toward the suture thread (100) fixed by the push plate (330), obliquely moves to the left or right, and forms a cut in an inclined shape on a surface of the suture thread (100) to form a cog.
