Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a magnesium fishbone wire and a preparation method thereof. Background Art

[0002] With the continuous improvement of people's living standards and the increasing demand for medical care by the general public, the medical plastic surgery industry has also been developing continuously. Medical cosmetology refers to the use of drugs, surgery, medical devices and other invasive or irreversible medical techniques to repair and reshape the appearance and shape of various parts of the human body.

[0003] The beauty thread is a commonly used cosmetic medical device. The beauty thread is provided with barbs. The beauty thread and the barbs have a filling and lifting effect on human tissue. When in use, the beauty thread is placed in the thread embedding needle. The beauty thread is located at one end of the thread embedding needle and extends out of the thread embedding needle and is bent and attached to the outer wall of the thread embedding needle. The thread embedding needle is inserted into the human tissue. When the thread embedding needle is pulled out, the beauty thread remains in the human tissue. The material of the beauty thread in the related art is protein thread or polymer thread, the wire material is cylindrical, and the preparation method is extrusion. The inventor believes that one end of the beauty thread in the related art is attached to the side wall of the thread embedding needle. When the beauty thread is inserted into the human tissue with the thread embedding needle, the barbs on the beauty thread will hinder the beauty thread from entering the human tissue, and further improvement is needed. Summary of the invention

[0004] In order to improve the cosmetic effect of cosmetic lines, the present application provides a magnesium herringbone line and a preparation method thereof.

[0005] In the first aspect, the present application provides a magnesium fishbone wire, which adopts the following technical solution:

[0006] A magnesium fishbone wire and a preparation method thereof, comprising a wire bone, wherein one end of the wire bone in the length direction is provided with a barb, an end of the wire bone close to the barb is provided with a plurality of lateral support rods, an end of the lateral support rod away from the wire bone is inclined in a direction away from the barb, an end of the wire bone away from the barb is provided with a plurality of reverse support rods, an end of the reverse support rod away from the wire bone is inclined in a direction close to the barb, and the wire bone, the barb, the lateral support rod and the reverse support rod are integrally formed.

[0007] By adopting the above technical scheme, a barb is provided on one end of the wire bone, and the end where the barb is located is inserted into the thread embedding needle, and the barb is hooked on the side wall of one end of the needle tip of the thread embedding needle. When the thread embedding needle is pulled out, the barb is hooked on the human tissue. After the thread embedding needle is pulled out, the magnesium fishbone wire will remain in the human tissue, and the forward branch rod and reverse branch rod on the magnesium fishbone wire will prevent the sliding of the magnesium fishbone wire in the human tissue, and the barb, the forward branch rod and the reverse branch rod will all have a lifting effect on the human tissue, thereby reducing the resistance encountered by the thread embedding needle when inserted into the human tissue, reducing the trauma to the human tissue when the thread embedding needle is inserted, improving the lifting effect on the human tissue, and effectively improving the cosmetic effect.

[0008] In a specific embodiment, the wire bones, the barbs, the directional struts and the reverse struts are all made of a magnesium base material.

[0009] In a specific embodiment, the magnesium substrate includes pure magnesium and magnesium alloys.

[0010] By adopting the above technical solution, magnesium is an essential macroelement in the human body, accounting for about 0.05% of human body weight. Magnesium participates in more than 300 enzymatic reactions as an enzyme activator. The magnesium fishbone wire made of magnesium can be absorbed by the skin, regulate the excitability of facial nerve muscles, and promote wound healing and recovery. Magnesium can be absorbed by the human body, so there is no need to remove the stitches. In addition, the magnesium forward and reverse struts have stronger strength, are not prone to breakage, and have stronger supporting strength for human tissues, thereby achieving a better lifting effect on human tissues.

[0011] In a specific possible implementation scheme, the linear bone is arranged in a square rod shape, a plurality of the lateral struts are located on two opposite sides of the linear bone, and the lateral struts are arranged symmetrically in pairs with respect to the linear bone, and a plurality of the reverse struts are located on two sides where the lateral struts are located, and the reverse struts are arranged symmetrically in pairs with respect to the linear bone.

[0012] By adopting the above technical solution, the forward struts and the reverse struts are arranged on the two sides of the wire bone. At the same time, the symmetrical arrangement of the forward struts and the symmetrical arrangement of the reverse struts can improve the uniformity of the pulling force of the magnesium herringbone wire on the skin on both sides of the magnesium herringbone wire.

[0013] In a specific possible implementation manner, the ends of the axial strut and the reverse strut away from the linear bone are both configured as curved tip ends.

[0014] By adopting the above technical solution, the curved tip can penetrate into the muscle and skin tissue, reducing the possibility of the magnesium fishbone wire falling off. The curved surface can reduce the stimulation to the tissue, thereby achieving a better cosmetic effect.

[0015] In a specific possible implementation manner, the distance between the arc-surface tips of two symmetric longitudinal struts with respect to the length direction of the linear bone is greater than the width of the barb.

[0016] By adopting the above technical solution, the width of the barb is narrow, so it is easy to insert the barb into the thread embedding needle. The distance between the arc tips of the longitudinal support rods symmetrical about the length direction of the thread bone is wide, which can improve the pulling strength of human tissue.

[0017] In a specific embodiment, the thicknesses of the wire bones, the barbs, the antegrade struts and the inverse struts are all the same.

[0018] By adopting the above technical scheme, the thickness of the wire bone, barbs, lateral struts and reverse struts are the same, which is convenient for the preparation of the magnesium herringbone wire. The pulling strength of the barbs, lateral struts and reverse struts on the magnesium herringbone wire on human tissue can also be more uniform, thereby improving the cosmetic effect of the magnesium herringbone wire.

[0019] In a specific possible implementation manner, the angles formed between the forward strut and the reverse strut and the linear bone are all set to be rounded angles.

[0020] By adopting the above technical solution, the rounded corners can reduce the possibility of secondary damage when muscle tissue is clamped.

[0021] In a second aspect, the present application discloses a method for preparing a magnesium fishbone wire, comprising the following steps:

[0022] Substrate preparation: cutting the magnesium substrate into magnesium blocks, and rolling the magnesium blocks into magnesium sheets;

[0023] Cutting: The magnesium sheet is leveled, and under nitrogen protection, laser cutting is used to cut out integrated wire bones, barbs, forward support rods and reverse support rods on the magnesium sheet to obtain a magnesium fishbone wire.

[0024] By adopting the above technical solution, the thickness of the magnesium sheet is processed to the same thickness as that required by the magnesium fishbone wire. The size of the magnesium fishbone wire is small, and traditional mold processing and tool cutting cannot form the magnesium fishbone wire. Therefore, laser cutting is adopted. Laser cutting can cut out the shape of the wire bone, barb, forward support rod and reverse support rod, and ensure the integrity of the wire bone, barb, forward support rod and reverse support rod. Nitrogen plays the role of isolating oxygen during cutting. The temperature of the magnesium plate is high when it is cut, and nitrogen reduces the possibility of oxidation of the magnesium plate.

[0025] In a specific embodiment, the nitrogen gas has a pressure of 0.8 MPa-1.0 MPa.

[0026] By adopting the above technical solution, in a nitrogen environment of 0.8MPa-1.0MPa, the magnesium plate is effectively protected and nitrogen is saved.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The present application hooks the side wall of one end of the needle tip of the thread embedding needle with a barb, so that the magnesium fishbone wire can enter the human tissue along with the thread embedding needle. When the thread embedding needle is withdrawn, the barb is hooked on the human tissue. After the thread embedding needle is withdrawn, the magnesium fishbone wire will remain in the human tissue. The barb, the forward support rod and the reverse support rod can all play a pulling effect on the human tissue, thereby reducing the resistance encountered when the thread embedding needle is inserted into the human tissue, reducing the trauma to the human tissue during the insertion of the thread embedding needle, improving the pulling effect on the human tissue, effectively improving the cosmetic effect, and reducing the healing time of the tissue.

[0029] 2. The present application adopts magnesium as the entire material of the magnesium fishbone wire. Magnesium can be absorbed by the human body, and after being absorbed by the human body, magnesium can promote the healing of facial wounds and has a beneficial effect on human health.

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] Example 1

[0036] Example 1 of the present application discloses a magnesium fishbone wire. Figure 1 A magnesium fishbone wire includes a wire bone 1, the material of the wire bone 1 is a magnesium base material, and embodiment 1 of the present application uses pure magnesium, which can be absorbed by the human body. The wire bone 1 is arranged in the shape of a long square rod. The length of the wire bone 1 is 100 mm, the width of the wire bone 1 is 0.396 mm, and the thickness of the wire bone 1 is 0.397 mm.

[0037] Reference Figure 2A barb 2 is provided at one end of the wire bone 1 in the length direction. The material of the barb 2 is a magnesium base material. The embodiment 1 of the present application uses pure magnesium, which can be absorbed by the human body. The thickness of the barb 2 is the same as that of the wire bone 1, and the width of the barb 2 is 0.752 mm. When in use, one end of the wire bone 1 where the barb 2 is located is inserted into the thread embedding needle, and the barb 2 is hooked on the side wall of the end where the needle tip of the thread embedding needle is located. The magnesium fishbone wire enters the human tissue with the thread embedding needle. When the thread embedding needle is withdrawn, the barb 2 hooks and pulls the human tissue, so that when the thread embedding needle is withdrawn, the magnesium fishbone wire can remain in the human tissue.

[0038] Reference Figure 2 , a number of lateral support rods 3 are arranged on both sides of the width direction of the wire bone 1. The material of the lateral support rods 3 is a magnesium base material. The embodiment 1 of the present application adopts pure magnesium, which can be absorbed by the human body. The lateral support rods 3 are located on the end of the wire bone 1 close to the barb 2. The thickness of the lateral support rods 3 is the same as the thickness of the wire bone 1. A number of lateral support rods 3 are symmetrically arranged in pairs about the wire bone 1. The end of the lateral support rod 3 away from the wire bone 1 is set as a curved tip 5 and tilted toward the end away from the barb 2. The distance between the curved tips of the two lateral support rods symmetrical about the wire bone 1 is 1.284mm. When the magnesium fishbone wire is in the human tissue, the magnesium fishbone wire and the lateral support rods 3 on the magnesium fishbone wire have a pulling effect on the human tissue. The angle formed between the lateral support rod 3 and the wire bone 1 is set as a fillet 6, and the fillet 6 can reduce the clamping strength of the human tissue and reduce the secondary damage to the human tissue.

[0039] Reference Figure 3 , a number of reverse struts 4 are arranged on both sides of the line bone 1 in the width direction. The reverse struts 4 are made of a magnesium base material. The embodiment 1 of the present application uses pure magnesium, which can be absorbed by the human body. The reverse struts 4 are located on the end of the line bone 1 away from the barb 2. The thickness of the reverse struts 4 is the same as the thickness of the line bone 1. The reverse struts 4 are arranged symmetrically about the line bone 1 in pairs. The end of the reverse struts 4 away from the line bone 1 is also set as a curved tip 5 and tilted toward the end close to the barb 2. The angle between the reverse struts 4 and the line bone 1 is also set as a fillet 6. When the line bone 1 enters the skin, the reverse struts 4 enter behind the forward struts 3. The forward struts 3 and the reverse struts 4 are tilted in opposite directions, thereby achieving a better lifting effect on the human tissue, and further preventing the magnesium fishbone wire from moving in the human tissue, thereby making the skin tighter and improving the beauty effect.

[0040] Reference Figure 1 The wire bone 1, the reverse support rod 4, the forward support rod 3 and the barb 2 are manufactured in one piece. The sizes of the wire bone 1, the reverse support rod 4, the forward support rod 3 and the barb 2 are all small. The one-piece molding can maintain a strong connection strength between each other. The reverse support rod 4, the forward support rod 3 and the barb 2 are not easy to break and fall off from the wire bone 1.

[0041] The implementation principle of a magnesium fishbone wire in an embodiment of the present application is as follows: the magnesium fishbone wire is inserted into the thread embedding needle, and when the thread embedding needle is inserted into the human tissue, the barb 2 is hooked on the side wall of the thread embedding needle, and will not cause excessive damage to the human tissue during the process of entering the human tissue. When the thread embedding needle is pulled out, the barb 2 is hooked on the human tissue, so that when the thread embedding needle is pulled out, the magnesium fishbone wire can remain in the human tissue, and the inclined directions of the forward support rod 3 and the reverse support rod 4 on the magnesium fishbone wire are opposite, which has a pulling effect on the human tissue, thereby making the skin tighter. The use of the reverse support rod 4 and the forward support rod 3 reduces the possibility of the magnesium fishbone wire coming out of the human tissue. In addition, the magnesium fishbone wire made of magnesium can be absorbed by the human body, and magnesium is beneficial to the human body, so the step of removing the stitches is eliminated.

[0044] Cutting: The magnesium sheet is leveled and placed in a nitrogen environment with an air pressure of 0.8 MPa, and clamped with a clamp. A laser cutting machine is used to cut an integrated wire bone 1, a hook 2, a forward support rod 3 and a reverse support rod 4 on the magnesium sheet, and an arc tip 5 is cut on the reverse support rod 4 and the forward support rod 3. The angle between the reverse support rod 4 and the wire bone 1 and the angle between the forward support rod 3 and the wire bone 1 are cut into a rounded corner 6. The power of the laser cutting machine is set to 1500 W, the frequency is set to 300 Hz, the pulse width is set to 100 us, and the linear speed is set to 8 mm / s.
