Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that the anchoring structure of the existing pulling wire will cause the mechanical properties of the pulling wire to decrease or defects to form at the anchoring part, making the pulling wire prone to break at the anchoring part during use and degradation, resulting in the failure of the pulling wire, and to provide a pulling wire and a preparation method thereof and a pulling system.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a pulling wire, comprising a wire body, a plurality of barbs disposed on the surface of the wire body, and a woven mesh in a mesh structure sleeved on the wire body. The top of the barb penetrates out of the woven mesh and inclines in the same direction, and the bottom of the barb is embedded in the woven mesh. The woven mesh is made of one of absorbable monofilament or absorbable multifilament.

[0005] Preferably, the wire diameter of the woven mesh is 0.095 - 0.199 mm, the wire diameter of the absorbable monofilament is 0.095 - 0.199 mm, and the wire diameter of the absorbable multifilament is 0.100 - 0.199 mm.

[0006] Preferably, the wire diameter of the wire body in the pulling wire is 0.25 - 0.61 mm, and the distance between barbs on the wire body is 1 - 5 mm.

[0007] Preferably, the length of the barb is 0.5 - 2 mm, the ratio of the barb depth to the wire diameter of the wire body is 0.1 - 0.3, and the inclination angle of the barb is 30° - 90°.

[0008] The present invention also provides a pulling system, comprising a pulling tool and the above-mentioned pulling wire. The pulling tool includes a handheld part and an installation part disposed at the bottom of the handheld part, and the pulling wire is connected to the bottom of the installation part.

[0009] Further, a notch is formed at the bottom of the installation part, and the surface of the pulling wire is exposed outside the notch and fits with the facial skin tissue during use.

[0010] The present invention provides a method for preparing a lifting wire material, comprising the following steps:

[0011] S1: Using a monofilament production device to produce an absorbable monofilament material as the main body of the wire;

[0012] S2: Using a cutting tooth machine to cut and stab the main body of the wire in S1, and forming a number of barbs on the main body of the wire. After cutting and stabbing, the main body of the wire forms an absorbable cut and stabbed wire;

[0013] S3: Using a knitting machine to knit the absorbable cut and stabbed wire in S2, knitting the absorbable material on the main body of the wire to form a knitted mesh with a mesh structure, and the top of the barb penetrates outside the knitted mesh.

[0014] Preferably, the absorbable material is one, two or a blend of two or more of poly(lactide), poly(glycolide), poly(p-dioxanone), poly(trimethylene carbonate), or a monomer copolymer of two or three of the above materials, and the monomer molar ratio range of the absorbable material is 70-85:30-0:0-15.

[0015] The present invention also provides another method for preparing a lifting wire material, characterized by comprising the following steps:

[0019] The beneficial effects of a lifting wire material, its preparation method and a lifting system provided by the present invention are as follows:

[0020] 1. The knitted mesh sleeved on the main body of the wire can effectively improve the wire strength of the core wire. The knitted mesh with a mesh structure is beneficial to improving the strength utilization rate of the main body of the wire in the stretching direction, thereby improving the overall mechanical strength of the knitted mesh composite lifting wire material, reducing the fracture risk of the lifting wire during use, and improving the lifting effect.

[0021] 2. When the core wire contacts the facial muscle tissue and degradation occurs, the braided net in a mesh structure on the wire body has combined with the muscle tissue. The combination of the braided net and the muscle tissue has a partial lifting effect on the tissue. And by using the pull wire made of absorbable material, it can effectively utilize the absorbable material to stimulate collagen regeneration and buffer the impact brought by the degradation and fracture of the wire body, so that the braided net composite pull wire still has a lifting effect after the anchoring structure of the core wire degrades and fails.

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] See Figures 1 - 6, A pulling wire 100 provided by the present invention. The pulling wire 100 includes a pulling wire 10, the pulling wire 10 includes a wire body 11 and a plurality of barbs 12 disposed on the surface of the wire body 11. It also includes a braided net 20 sleeved on the wire body 11 and having a mesh structure. The top ends of the barbs 12 penetrate outside the braided net 20 and incline in the same direction, and the bottoms of the barbs 12 are embedded in the braided net 20. The braided net 20 in the pulling wire 100 provided by the present invention can be one of absorbable monofilaments or absorbable multifilaments. When the braided net 20 made of absorbable monofilament material is used, the wire strength of the pulling wire 10 can be effectively improved. The absorbable monofilament material braided net 20 having a mesh structure is beneficial to improving the strength utilization rate of the wire body 11 in the stretching direction, thereby improving the overall mechanical strength of the pulling wire 100 and reducing the fracture risk of the pulling wire during use. The absorbable monofilament provided by the present invention is an absorbable material, so as to effectively utilize the absorbable material to stimulate collagen regeneration and further effectively improve the lifting effect. When the braided net 20 made of absorbable multifilament material is used, after the anchoring structure of the pulling wire 10 degrades and fails, through the braided net 20 made of absorbable multifilament material, when the pulling wire 10 contacts the facial muscle tissue and degrades, the braided net 20 having a mesh structure on the wire body 11 has been combined with the muscle tissue, and the combination of the braided net 20 and the muscle tissue has a partial lifting effect on the tissue. The absorbable multifilament provided by the present invention is an absorbable material, so as to effectively utilize the absorbable material to stimulate collagen regeneration, so that the pulling wire 100 still has a lifting effect after the anchoring structure of the pulling wire 10 degrades and fails. The wire body 11 in the present invention can be one of absorbable cutting wires or absorbable embossed fishbone wires.

[0030] As Figure 1 and Figure 3 shown, use D1 to represent the wire diameter of the wire body 11 in the present invention, and use D2 to represent the wire diameter of the braided net 20 in the present invention. Among them, the value range of the wire diameter D2 of the braided net 20 is 0.095 - 0.199 mm. Experiments show that when the braided net 20 made of absorbable monofilament material is used, the effect is better when the value range of the wire diameter D2 of the braided net 20 is 0.095 - 0.199 mm. When the braided net 20 made of absorbable multifilament is used, the effect is better when the value range of the wire diameter of the braided net 20 is 0.100 - 0.199 mm. The value range of the wire diameter D1 of the wire body 11 in the pulling wire 10 is 0.25 - 0.61 mm.

[0031] As Figure 3 and Figure 4As shown in the figure, let L1 represent the length of the barb 12 (i.e., the distance from the outer root to the top of the barb 12), and let L2 represent the distance between adjacent barbs 12 on the wire body 11. Among them, the value range of the length L1 of the barb 12 is 0.3 - 2 mm, and the distance between adjacent barbs 12 on the wire body 11 is 1 - 5 mm.

[0032] Figure 4 The figure shows the included angle relationship between the barb 12 and the length direction of the wire body 11. In the figure, 30 represents the center line of the wire body 11, 40 represents the center line of the barb 12, and Φ represents the included angle between the center line 30 of the wire body 11 and the center line 40 of the barb 12, that is, the included angle between the length direction of the wire body 11 and the barb 12. Through experiments, it is shown that when this included angle is 30° - 90°, the effect is better, and the barb 12 can be perpendicular to the surface of the wire body 11.

[0033] Figure 4 The figure also shows the relationship between the depth of the barb 12 (i.e., the distance that the root of the barb 12 extends into the surface of the wire body 11, calculated perpendicular to the length direction of the wire) and the wire diameter D1 of the wire body 11. Among them, H represents the depth of the barb 12. Experiments show that when the ratio of the depth H of the barb 12 to the diameter D1 of the wire body 11 is 0.01 - 0.3, the effect is better.

[0034] The present invention also provides a lifting system 200, which includes a lifting tool 201 and the above-mentioned lifting wire 100. The lifting tool 201 includes a handheld part 2011 and an installation part 2012 provided at the bottom of the handheld part. The lifting wire 100 is rotatably connected to the bottom of the installation part 2012. A notch 2012a is formed at the bottom of the installation part 2012, and the surface of the lifting wire 100 is exposed outside the notch 2012a and fits with the facial skin tissue. The doctor holds the handheld part 2011 of the lifting tool 201 and, after the exposed part outside the notch 2012a fits with the facial skin tissue, lifts the handheld part 2011, which can make the lifting wire 10 drive the knitting net 20 to rotate in the installation part 2012 of the lifting tool 201 under the resistance of the facial skin tissue, so that the barbs 12 of the lifting wire 10 and the knitting net 20 are combined with the body tissue. The lifting wire provided by the present invention is a biodegradable material, which can effectively utilize the biodegradable material to stimulate collagen regeneration, achieve the effect of facial lifting, and effectively improve the convenience and safety of the doctor's operation.

[0035] A manufacturing method of a lifting wire provided by the present invention includes the following steps:

[0036] S1: Use a monofilament production device to produce a biodegradable monofilament material as the wire body;

[0037] S2: Use a cutting machine to cut and prick the wire body in S1, and form a number of barbs on the wire body. The wire body after cutting and pricking forms an absorbable cutting wire;

[0038] S3: Use a knitting machine to knit the absorbable cutting wire in S2, and knit the absorbable material on the wire body to form a knitted mesh with a mesh structure. The top of the barb penetrates outside the knitted mesh.

[0039] In the manufacturing method of the knitted mesh composite lifting wire provided by the present invention, the single-filament production equipment mentioned selects the MC-WSTEST type single-filament production equipment (serial number SC183) to produce the wire body. The cutting machine is the XCQG-1 type wire cutting machine to cut and prick the wire body. Put the absorbable cutting wire formed after cutting and pricking into an 8-spindle knitting machine (serial number SC371). After centrally connecting with the yarn in the knitting machine, connect it with the previously reserved traction wire, so as to adjust the position of the connection point between the absorbable cutting wire and the yarn, make the absorbable cutting wire in the middle of the yarn and perpendicular to the limit steel ring of the knitting machine. Subsequently, adjust the parameters of the knitting machine to a section length of 300 mm and a sub-rotation speed of 10 r / m, so as to knit the absorbable material on the wire body to form a knitted mesh with a mesh structure.

[0040] The absorbable material provided by the present invention is one or a blend or copolymer of two or more of the following materials: poly(lactide), poly(ε-caprolactone), poly(p-dioxanone), trimethylene carbonate. Through experimental determination, when the molar ratio range of the absorbable material is 70 - 85:30 - 15, the lifting effect is better.

[0041] The present invention also provides another manufacturing method of the lifting wire: including the following steps:

[0042] S1: Use the embossed fishbone wire as the wire body;

[0043] S2: Use a knitting machine to knit the wire body described in S1, and knit the absorbable material on the wire body to form a knitted mesh with a mesh structure.

[0044] The embossed fishbone wire also has a plurality of barbs, and the barbs penetrate outside the knitted mesh.

[0045] Through experimental determination, when a braided mesh made of absorbable monofilament material is used, it can effectively improve the wire strength of the core wire. The braided mesh made of absorbable monofilament material in a mesh structure is beneficial to improving the strength utilization rate of the wire body in the stretching direction, thereby improving the overall mechanical strength of the braided mesh composite lifting wire, reducing the risk of breakage of the lifting wire during use. The absorbable monofilament provided by the present invention is an absorbable material, so as to effectively utilize the absorbable material to stimulate collagen regeneration, and further effectively improve the lifting effect. When a braided mesh made of absorbable multifilament material is used, after the anchoring structure of the core wire degrades and fails, the degradation time of the core wire can be effectively adjusted and controlled through the braided mesh made of absorbable multifilament material. Since the degradation time of the braided mesh made of absorbable multifilament material is longer than that of the core wire, after the anchoring function of the core wire with an anchoring structure fails, the knot structure of the braided mesh has been combined with the body tissue, and this combination has a partial lifting effect on the tissue. The absorbable multifilament provided by the present invention is an absorbable material, so as to effectively utilize the absorbable material to stimulate collagen regeneration and buffer the impact brought by the degradation and breakage of the lifting wire, so that the braided mesh composite lifting wire still has a lifting effect after the anchoring structure of the core wire degrades and fails.
