Abstract
The invention provides a kind of medical treatment suture, including line main body, described line main body includes the monomer line that two strips are identical, described monomer line axial cross section is semicircle, it is circular line main body that described two monomer lines are merged into an axial cross section by the way of direct pressing, is made by techniques such as single line molding and single line joints and obtains finished product suture.Finished product suture has the advantages such as good toughness, flexible, diameter is little so that sew up more smooth, and the injury causing human body is less.
Description
Technical field
The present invention relates to a kind of medical treatment suture, specifically refer to a kind of medical treatment suture and preparation method thereof.
Background technology
Medical treatment suture be for the dedicated line sewed up a wound in surgical operation, be in surgical operation requisite stage property it
One.Medical treatment suture not only to ensure have bigger flexibility and toughness, will not be broken easily, simultaneously the diameter of suture to be ensured
Little.The diameter of the suture speed that doctor sews up a wound during too conference has a strong impact on operation process and accuracy, and thicker seam
The tissue passed can be caused injury in various degree by line, especially the vital tissues such as human body viscera is easily caused injury.
Therefore, in operation process, in the case of ensureing that suture toughness is enough, all select the suture that diameter is little to carry out stitching process.
Traditional suture, in order to ensure enough toughness, uses a plurality of single-wire helix shape to be wound in a toughness and flexibility relatively
Big suture；Or a plurality of single line is placed in parallel, it is combined into a high tenacity and the seam of high flexibility by the method for external stability
Line.But its diameter of the suture that this kind of mode is combined into can increase a lot, although ensure that the toughness of suture, but easily in operation
In the tissue sewed up is caused and injures largely.
Summary of the invention
The invention aims to provide a kind of good toughness, flexible, diameter is little, can avoid in sewing process people
Body causes the medical suture of bigger wound, with and preparation method thereof.
In order to achieve the above object, the technical scheme is that a kind of medical treatment suture, including line main body, institute
Stating the monomer line that line main body includes that two strips are identical, described monomer line axial cross section is semicircle, described two monomer lines
Being merged into an axial cross section by the way of direct pressing is circular line main body；
The method making described medical treatment suture specifically includes following steps:
A single line molding: single suture is put into string-pressing device, is that semicircular mould is by single seam by axial cross section
Line is pressed into axial cross section and is similarly semicircular monomer line；
B single line engages: use string-pressing device, and it is circular that two direct pressings of monomer line become an axial cross section
Line main body.
In described step b, the Combination of Methods that monomer line is merged by heat becomes line main body.
In described step b, monomer line forms line main body by viscose.
Beneficial effects of the present invention: due to use two semicircle single lines form by the way of direct pressing one transversal
Face is circular combination suture, and relative to the monomer suture of same diameter, it is flexible more preferably.It is wound around relative to traditional bifilar helix
Combining the suture of combination parallel with two-wire, the diameter of medical treatment suture of the present invention is less, therefore, during this medical treatment suture
Subject to less resistance, the least to human injury during stitching, make stitching be more prone to simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the cross sectional representation of a kind of medical treatment suture of the present invention.
1, line main body；2, monomer line.
Detailed description of the invention
We combine accompanying drawing and are further described a kind of medical treatment suture of the present invention and preparation method thereof below.
As it is shown in figure 1, a kind of medical treatment suture of the present embodiment and preparation method thereof, including line main body 1, line main body 1 includes
The monomer line 2 that two strips are identical, monomer line 2 axial cross section is semicircle, and two monomer lines 2 are by the way of direct pressing
Being merged into an axial cross section is circular line main body 1；
The described method making medical treatment suture specifically includes following steps:
A single line molding: single suture is put into string-pressing device, is that semicircular mould is by single seam by axial cross section
Line is pressed into axial cross section and is similarly semicircular monomer line 2；
B single line engages: use string-pressing device, direct for two monomer lines 2 pressing becomes an axial cross section for circle
Line main body 1.Common, ensureing that suture toughness is enough, in the case of will not rupturing during use, prioritizing selection diameter is the least
Suture, the flexible of minor diameter suture preferably and is not easy to damage suture site, ties a knot the lightest.With
As a example by the monofilament of 0.45mm, in order to ensure that the monofilament of 0.45mm has enough toughness, traditional spiral winding mode and two-wire flat
The mode that row is placed, after two combination of monofilaments of its 0.45mm, diameter is generally about 0.9mm.And if using the present embodiment
The compound mode of described medical suture, is multiplied by 0.45 according to formula 0.45 and is multiplied by 0.785 equal to 0.68, final combination suture
A diameter of 0.68mm.Compared to traditional mariages compound mode, the diameter of the medical suture of the present embodiment reduces 0.22mm,
In the case of ensure that toughness, largely decrease due to the excessive injury that suture site is caused of suture diameter, simultaneously
Also reduce frictional resistance so that sewing process is more smooth.Heretofore described monomer line 2 quantity is two, according to tool
Body needs to be changed to three or more than three.
In the present embodiment, in described step b, the Combination of Methods that monomer line 2 is merged by heat becomes line main body 1.Described step b
In, monomer line 2 forms line main body 1 by viscose.Above-mentioned is conventional combination suture mode.
The invention is not restricted to above example and conversion, present invention is the most simply changed by those skilled in that art
Dynamic, belong to protection scope of the present invention.
