Abstract
The invention provides a medical suture. The medical suture comprises a suture body, the suture body comprises two single sutures which are in the same shape, axial cross sections of the single sutures are semicircular, the two single sutures are combined in a direct press-fit mode to form the suture body with a circular axial cross section, and a finished product suture can be achieved by crafts such as single-suture forming and single-suture joint. The finished product suture has the advantages of good tenacity and flexibility, small diameter and the like, thereby, suturing is smooth, and harm to a human body is small.
Description
Technical field
The present invention relates to a kind of medical suture, specifically referred to a kind of medical suture and preparation method thereof.
Background technology
Medical treatment suture be in surgical operation for the dedicated line of sew up wound, be one of requisite stage property in surgical operation.Medical treatment suture not only will ensure larger flexibility and toughness, can not broken easily, also will guarantee that the diameter of suture is little simultaneously.The diameter of suture too conference has a strong impact on speed and the accuracy of doctor's sew up wound in operation process, and thicker suture can cause injury in various degree to the tissue of passing, and especially the vital tissues such as human body viscera is easily damaged.Therefore,, in operation process, in the situation that guaranteeing that suture toughness is enough, all select the suture that diameter is little to sew up processing.
Traditional suture, in order to guarantee enough toughness, adopts many single-wire helix shapes to be wound in a toughness and the larger suture of flexibility; Or many parallel placements of single line, by the method for external stability, be combined into the suture of a high tenacity and high flexibility.But its diameter of suture that this class mode is combined into can increase a lot, although guaranteed the toughness of suture, easily in operation, the tissue of sewing up is caused to injury largely.
Summary of the invention
The object of the invention is for a kind of good toughness is provided, flexible, diameter is little, can avoid in sewing process, human body being caused the medical suture of larger wound, with and preparation method thereof.
In order to achieve the above object, the invention provides following technical scheme: a kind of medical suture, comprise line main body, described line main body comprises the monomer line that two strips are identical, described monomer line axial cross section is semicircle, and it is circular line main body that the mode of described two monomer lines by direct pressing is merged into an axial cross section;
The method of making described medical suture specifically comprises the steps:
A single line molding: single suture is put into string-pressing device, is that semicircular mould is pressed into axial cross section by single suture and is similarly semicircular monomer line by axial cross section;
B single line engages: use string-pressing device, it is circular line main body that two direct pressings of monomer line are become to an axial cross section.
In described step b, the Combination of Methods that monomer line merges by heat becomes line main body.
In described step b, monomer line forms line main body by viscose.
Beneficial effect of the present invention: be circular combination suture because the mode that adopts two semicircle single lines by direct pressing forms a sliver transvers section, with respect to the monomer suture of same diameter, it is flexible better.With respect to traditional bifilar helix, be wound around the suture of combination and the parallel combination of two-wire, the diameter of medical suture of the present invention is less, and therefore, the resistance that this medical treatment suture is subject to while sewing up is less, also less 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 suture of the present invention.
1, line main body; 2, monomer line.
The specific embodiment
Below we are further described a kind of medical suture of the present invention and preparation method thereof by reference to the accompanying drawings.
As shown in Figure 1, a kind of medical suture of the present embodiment and preparation method thereof, comprise line main body 1, line main body 1 comprises the monomer line 2 that two strips are identical, monomer line 2 axial cross sections are semicircle, and it is circular line main body 1 that two monomer lines 2 mode by direct pressing is merged into an axial cross section;
The method of the medical suture of described making specifically comprises the steps:
A single line molding: single suture is put into string-pressing device, is that semicircular mould is pressed into axial cross section by single suture and is similarly semicircular monomer line 2 by axial cross section;
B single line engages: use string-pressing device, it is circular line main body 1 that the direct pressing of two monomer lines 2 is become to an axial cross section.Common, guaranteeing that suture toughness is enough, in the situation that can not rupture during use, preferentially select the suture that diameter is comparatively little, the flexibility of minor diameter suture is better, and is not easy suture site to damage, and ties a knot also lighter.The monofilament of 0.45mm of take is example, in order to guarantee that the monofilament of 0.45mm has enough toughness, and traditional spiral winding mode and the mode of the parallel placement of two-wire, after two combination of monofilaments of its 0.45mm, diameter is generally 0.9mm left and right.And if adopt the compound mode of the medical suture described in the present embodiment, according to formula 0.45, be multiplied by 0.45 to be multiplied by 0.785 and to equal 0.68, the diameter that finally combines suture is 0.68mm.Compared to traditional mariages compound mode, the diameter of the medical suture of the present embodiment has reduced 0.22mm, in the situation that having guaranteed toughness, has reduced to a great extent due to the excessive injury that suture site is caused of suture diameter, also reduced frictional resistance, make sewing process more smooth simultaneously.Monomer line 2 quantity described in the present invention are two, also can be changed to more than three or three according to specific needs.
In the present embodiment, in described step b, the Combination of Methods that monomer line 2 merges by heat becomes line main body 1.In described step b, monomer line 2 forms line main body 1 by viscose.Above-mentioned is conventional combination suture mode.
The invention is not restricted to above embodiment and conversion, those skilled in that art simply change arbitrarily content of the present invention, all belong to protection scope of the present invention.
