Description
Technical field
The present invention relates to a kind of operation suture thread, and in particular to a kind of preparation method of the 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 a kind of preparation method of operation suture thread, and it is given birth to

Power roller and a stress groove, uniform Disjunct distribution has multiple projections vertically on pressure roll, and the section of projection has first end
With the second end, first end is in half elliptic, and the second end is rectangular, is in multiple zigzag between first end and the second end, zigzag
For right angled triangle, the right-angle side of right angled triangle is close to the second end, and the hypotenuse of right angled triangle is close to first end, while right angle
The direction on side is consistent with the axial direction of pressure roll；Width of the width of stress groove not less than the section of projection；After heating
Heavy denier yarn line is at the uniform velocity extruded heavy denier yarn line and made by the centre position of stress groove, multiple projections interruption of uniform Disjunct distribution
Obtain and be evenly distributed with Part II on heavy denier yarn line；
Step（4）Punching：By perforating device, the middle position of the Part II on heavy denier yarn line is punched, Kong Weichang
Bar shaped；
Step（5）Cooling winding：By step（4）Obtained heavy denier yarn line carries out cooling winding, that is, obtains the operation seam of pre-knotted
Zygonema.
Preferably, step（1）The section of obtained heavy denier yarn line is circle.
Preferably, step（4）In punching, hole is shaped as rectangle or ellipse.
Preferably, step（1）The middle high polymer material used is degradable material, it is highly preferred that degradable material is poly-
Glycolide.
Preferably, in step（1）Anti-inflammation hemostasia medicine is also added into during melt spinning, in raw material.
In addition, the spacing distance of multiple projections of uniform Disjunct distribution can be according to being actually needed vertically on pressure roll
Set, the interval of such as suture needle.
Pass through rate-determining steps（4）The shape and step of perforating mold during punching（3）The shape of projection during silk pressing, can
A kind of operation suture thread of pre-knotted, including Part I and Part II, Part I and Part II interval is prepared
Distribution, the cross-sectional width of the Part I of operation suture thread is uniform, and the cross-sectional width of Part II is wider than the section of Part I
Degree is big, and first end and the curved rounding off of Part I of Part II, the second end margin of Part II is perpendicular to operation

Angular sawtooth, the right-angle side of sawtooth is close to the second end of Part II and perpendicular to the axial direction of operation suture thread, sawtooth
Hypotenuse close to Part II first end；The hole of strip is provided with Part II interior central position, the length in the hole is not
Longitudinally wide less than Part II, the width in the hole is not less than the cross-sectional width of Part I.
Meanwhile present invention also offers a kind of sewing method of the operation suture thread of pre-knotted, using exempting from for above-mentioned preparation
The operation suture thread of knotting sutures to wound, in one pin of every suture, due to having Part II on suture, and second
Point first end be rounding off so that suture facilitates penetration of muscle under a stretching force, and due to the of Part II
And also there is sawtooth portion in two end margins so that perpendicular to the axial direction of operation suture thread through after muscle in Part II
Suture be not easy to slip；Now, then muscle surface is crossed into suture needle and penetrate when suturing this pin and through before muscle most
In the elongate holes of a near Part II, further prevent operation suture thread from slipping therefrom, in this way, carrying out next pin again
Suture, until during last pin, then last knot.Thus, a pin need not be often sutured in whole sewing process just to knot, so as to
Reduce suture time.
Beneficial effect
Compared with prior art, the present invention has the advantages that：The operation suture thread of a kind of pre-knotted of the present invention, in hand
It need not knot in art sewing process and easily produce, can successfully pass through muscle, and be not easy to try to shirk responsibility, suture
When, utilize the hole of the strip of the Part II in operation suture thread, moreover it is possible to successfully lock each pin, it is not easy to try to shirk responsibility, save
The knotting time about during suture needle, sewing process can be more quickly completed, mitigates the pain of patient.Meanwhile use can drop
Material production operation suture thread is solved, can avoid taking out stitches, further mitigate the pain of patient.And add and disappear in operation suture thread
Scorching hemostatic, be advantageous to the quick of wound and be cured.
