Description
Technical field
The present invention relates to a kind of operation suture thread, and in particular to a kind of operation suture thread of pre-knotted.
Background technology
Traditional operation suture thread is non-absorbing line, using in such suture after surgery sewing process, caused by wound
It is larger, also need to be taken out stitches after wound healing, cause secondary insult, cause recovery time also longer；And suture is general
All it is the line of whole piece, operation consent is needed to waste the plenty of time to try to make a match, and when needing to do continuous suture, the first pin often will
Several knots are accomplished fluently after suture to prevent operation suture thread from phenomenon of trying to shirk responsibility occur.But because the space of wound site is limited, so
The mode of operation not only can additionally increase some numerous and diverse steps, can also extend operating time and anesthesia duration accordingly, cause
Make the increase of patient risk's coefficient.
Do not knotted even to reduce to knot, shorten operating time, Application No. CN201120279072.6, Granted publication
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, suitable for double end needle construction, the double-ended needle operation sewing needle is made up of needle body with the syringe needle for being distributed in needle body both ends.
Subtract an operation suture thread from centre to hangnail of the both sides formed with symmetrical structure, in continuous suture due on operation suture thread
Hangnail so that the tissue passed through affords tension force, it is therefore prevented that the generation slip phenomenon of suture during continuous suture.But this hand
Art suture is not easy to produce, and because the material of operation suture thread is generally the material of flexible soft, only using only barb structure
It can not replace knotting completely.Therefore, operation suture thread is knotted in sewing process and easily produce, be
Those skilled in the art's technical issues that need to address.
The content of the invention
Above-mentioned technical problem be present for prior art, the present invention provides one kind and can not needed in surgical suturing process
