Description
Technical field
The utility model relates to a kind of operation suture threads, and in particular to a kind of operation suture thread of pre-knotted.
Background technique
Traditional operation suture thread is non-absorbing line, using in such suture after surgery sewing process, caused by wound
It is larger, it also takes out stitches after wound healing, causes secondary insult, cause recovery time also longer；And suture is general
It is all whole line, operation consent needs to waste the plenty of time to try to make a match, and when needing to do continuous suture, the first needle is often wanted
Several knots are accomplished fluently after suture to prevent operation suture thread from phenomenon of trying to shirk responsibility occur.But since the space of wound site is limited, in this way
The mode of operation not only can additionally increase some many and diverse steps, can also extend operating time and anesthesia duration accordingly, cause
Increase patient risk's coefficient.
It knots or even does not knot to reduce, shorten operating time, application No. is CN201120279072.6, Granted publications
Number for CN202161363U utility model patent disclose it is a kind of subtract an operation suture thread suitable for double-ended needle, this subtracts a hand
Art suture, is suitable for double end needle construction, which is made of needle body with the syringe needle for being distributed in needle body both ends.
Subtract the hangnail that an operation suture thread is formed with symmetrical structure from centre to two sides, in continuous suture due on operation suture thread
Hangnail, so that the tissue passed through affords tension, it is therefore prevented that the generation slip phenomenon of suture when continuous suture.But this hand
Art suture is not easy to produce, and since the material of operation suture thread is generally the material of flexible soft, and barb structure is only used only
It can not replace knotting completely.Therefore, so that operation suture thread is not needed the production that knots and be easy in sewing process, be
Those skilled in the art's technical issues that need to address.
