Title:
APPARATUS FOR FORMING COGS ON SURGICAL THREAD AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/069042
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for forming cogs on a surgical thread and a method therefor. The present invention provides an apparatus for forming cogs on a surgical thread, comprising: a bobbin (110) having a suture thread (100) wound thereonto; first and second tension rolls (200, 210) for maintaining, at regular tensions, the suture thread (100) unwound from the bobbin (110); a pair of friction rolls (300) for drawing the suture thread (100) and allowing the suture thread (100) to pass through so as to be discharged through an outgoing side; a tension plate (330) operating up and down, for temporarily fixing the suture thread (100) being discharged through the outgoing side by the friction roll (300); and a cog-forming knife (400) for forming cogs by rotating and simultaneously moving forward toward the suture thread (100) fixed by the tension plate (330) and also obliquely moving to the left or the right so as to make oblique cuts on the surface of the suture thread (100). According to the present invention, it is possible to obtain the effects of: improving productivity and increasing production yield rate due to automatic formation of the cogs; improving quality due to sequential and sophisticated formation by a program control; and reducing manufacturing costs due to enabling mass production.
