Abstract
Description
[0001] This application is a divisional application of a patent application with an application date of January 20, 2022, an application number of 202280030461.6, and an invention name of “Lifting wire for nose plastic surgery and its manufacturing method”. Technical Field
[0002] The present invention relates to a lifting thread, and more particularly, to a lifting thread for nose plastic surgery. Background Art
[0003] The typical symptoms of skin aging are sagging and wrinkles. Midface lift, a method to improve these conditions, is a surgical treatment that involves pulling the skin in one direction to remove excess skin and then suturing it, but there is a risk of scarring and side effects.
[0004] In order to move away from surgical methods, a lift surgery has been developed, in which harmless sutures with protrusions that can mechanically stretch the skin are implanted into the skin, inducing a natural immune response (foreign body reaction) in the human body, triggering collagen synthesis, angiogenesis, fat decomposition, etc., promoting skin regeneration, and then using the tension of the lift thread to lift and fix the sagging skin tissue. Compared with surgical methods, this is simple and does not produce side effects, so the frequency of surgery is increasing.
[0005] In this type of surgery, in particular, a lifting thread for nose plastic surgery is used to correct a collapsed nose tip, a crooked nose, or a low nose bridge. The two ends of the lifting thread are implanted in the subcutaneous layer of the nose so that the lifting thread supports the nose in a predetermined shape to create a fuller feeling or raise the nose bridge. At this time, the lifting thread is inserted into the bridge of the nose and the columella separately.
[0006] When a lifting thread is implanted inside the nose to support the shape of the nose, the nose tries to return to its original shape, so it continues to be subjected to tension over time. During this process, the thread moves inside the nose, and one end of the lifting thread irritates the skin, resulting in inflammation or protrusion through the skin. In this case, the lifting thread must be removed eventually, and problems such as tissue damage may occur during this process. In addition, the nose surgery so far only supports the bridge of the nose and the columella with the thread, but not the tip of the nose, so the effect on the tip of the nose is limited.
[0007] Therefore, there is an urgent need to develop a lifting wire for nose plastic surgery that is different from the existing lifting wire and that prevents protrusion to the outside or inflammation during nose plastic surgery and improves the conventional limit in the form of supporting the nose tip. Summary of the invention

[0019] Solutions to the problem
[0020] According to one embodiment of the present invention, a method for manufacturing a lifting thread may include: forming a lifting thread including a first region and a second region each forming a serration; and applying pressure while the first region and the second region are bent at a first angle to form a connecting region.
[0021] The lifting thread according to the present invention is characterized in that it includes a first area, a second area and a connecting area connecting the first area and the second area, and the maximum diameter of the cross section of the connecting area cut perpendicular to the central axis is longer than the maximum diameter of the cross section of the first area and the second area.
[0022] According to one embodiment of the present invention, the lifting line includes a first lifting portion, which includes one or more first serrations, and the cross-section of the first serration can be formed by a first side and a second side, the first side forms an acute angle with a first direction formed from one side to the other side of the length direction of the lifting line, and the second side forms a right angle or an obtuse angle with the first direction.
[0023] A lifting line according to one embodiment of the present invention is characterized in that it includes a first lifting portion having one or more negative-angle serrations, wherein a cross-section of the negative-angle serrations includes a first side forming a first angle from a surface of the lifting line to an inner side and a second side forming a second angle from the surface to an inner side, and at least one of the first angle and the second angle is an obtuse angle.
[0024] The lifting wire according to one embodiment of the present invention includes two different kinds of serrations, so that one lifting wire can be used to perform lifting surgery on the columella and the nose bridge and can have a structure that is conducive to ensuring the fixing force required for the lifting surgery.
[0025] According to an embodiment of the present invention, the lifting thread is formed such that at least one sawtooth is formed by two surfaces that form an obtuse angle with respect to the surface, and is formed as an obtuse-angle sawtooth implanted inside, so that even if it is discharged from the sleeve in the reverse direction, the lifting thread can be easily discharged from the sleeve without causing a stuck phenomenon. In addition, since the negative-angle sawtooth is formed, the thickness of the lifting thread becomes thicker, which can improve the surgical effect.

In detail, the angle deformation can be performed by a lifting wire, such as raising the nose bridge or raising the nose tip.
[0029] In addition, by using a lifting thread for rhinoplasty, it is not necessary to set the end of the lifting thread at a location such as the tip of the nose. Therefore, while improving the rhinoplasty effect, even if it is set in the skin tissue for a long time, there will be no problem of inflammation caused by one end of the lifting thread approaching the epidermis or protruding through the epidermis, and the tip of the nose shaping effect can be improved.
[0030] According to the lifting thread for nose plastic surgery of the present invention, by forming the thickness of the thicker connection area, the pressure on the cartilage set in the nose tip due to the lifting thread can be reduced, the pain suffered by the surgeon due to the operation can be reduced, and the deformation or damage of the cartilage in the nose tip can be prevented, and the nose tip can be supported, thereby improving the tip plastic surgery effect.

[0082] Figure 1 The figure shows a method for manufacturing a nose shaping lifting thread according to one embodiment of the present invention.
[0083] Reference Figure 1 The manufacturing method S10 of the lifting thread for nose plastic surgery may include a forming step S11 and a pressurizing step S12. In the forming step S11, the lifting thread including the first region and the second region may be injection molded or molded. The lifting thread is a thread made for the purpose of surgical operation, especially for nose plastic surgery, and is a thread made by a lifting operation for raising the nose bridge or raising the nose tip angle, and may be called a lifting thread or other names.
[0084] The first area and the second area of the lifting thread can be determined according to the implantation position during the lifting surgery. In one example, the first area of the lifting thread can correspond to the bridge of the nose located at the upper part of the nose, and the second area of the lifting thread can correspond to the columella located at the lower part of the nose. The first area and the second area can be manufactured in different forms. Figure 2 Described in detail in.
[0085] In one embodiment, in the step S11 of forming the lifting line, the lifting line can be injection molded or molded by injecting raw materials into a mold having a first area and a second area. In one example, the raw materials may include at least one of polydioxanone, polylactic acid, polyglycolic acid, polycaprolactone, and copolymers thereof, but this is only an example, and the technical idea of the present invention is not limited thereto. The lifting line injected or molded by the raw materials can be elastic as a whole. In one embodiment, when the raw materials are implanted into the human body, due to their absorbability, they may be absorbed by the skin tissue and disappear over time. Therefore, the surgical burden of the operator can be reduced by non-permanent materials.
[0086] In another embodiment, the lifting wire may be formed of a temperature-recoverable material (e.g., a shape memory alloy). In the above embodiment, the lifting wire may have a predetermined angle at body temperature, and an angle suitable for the person being operated on may be stored in the lifting wire. Since the lifting wire recovers the predetermined angle inside the body, the lifting operation may be effectively performed.
[0087] A connection area may be formed in a portion connecting the first area and the second area of the lifting line. In the pressurizing step S12, the first area and the second area of the lifting line are pressurized in a state of being bent at a predetermined angle, so that the connection area may be formed. In one embodiment, the predetermined angle may have any value in the range of 60 degrees to 150 degrees. In one embodiment, the pressurizing step S12 may be implemented at a predetermined temperature, and in one example, the predetermined temperature may have any value between 40 degrees Celsius and 60 degrees Celsius.
[0088] According to the technical concept of the present invention, the connection area is formed at a predetermined angle, so that the lifting line can be formed in a manner corresponding to the shape of the nose. When a nose lift surgery is performed using the lifting line formed according to the present invention, the surgery can be performed using a lifting line of a shape suitable for the angle of the patient's nose tip, and since a force is generated to try to maintain the predetermined angle without drilling into the internal tissue, even if the lifting line is set for a long time, damage to the internal tissue can be minimized, and the fixing force of the lifting line to fix the shape of the nose is increased, so that the nose plastic surgery effect can be maintained for a long time.
[0089] In addition, in the past, two lifting wires were used for lifting surgery, so the length of the nose bridge and the length of the columella were different for each patient. In some cases, the lifting wire was left, and in other cases, the lifting wire was insufficient. Therefore, the lifting wire constantly stimulated the nasal epidermis of the operated person to cause inflammation or penetrate and protrude, or failed to apply force at the correct position, ultimately causing physical problems for the operated person.
[0090] On the contrary, if the lifting thread formed according to the present invention is used, a lifting thread connecting the bridge of the nose and the columella can be used to perform a lifting operation. Since the connecting area between the first area and the second area is located at the tip of the nose, the problem of irritating the epidermis of the tip of the nose is reduced. By placing the connecting area at the tip of the nose, there is no need to cut the lifting thread according to the operator at the operating site, thereby greatly improving the convenience of the operation.
[0091] Figure 2 2 is a diagram illustrating a wire lifting method according to an exemplary embodiment of the present invention.
[0092] Reference Figure 2 , the lifting thread 100 may include a first region 110, a second region 120, and a connecting region 130. In one example, the first region 110 may correspond to the nose bridge of the operated person, the second region 120 may correspond to the columella of the operated person, and the connecting region 130 may correspond to the nose tip of the operated person. The connecting region 130 may be formed to be gradually thickened so that it has a cross-sectional area thicker than that of the first region 110, and the connecting region 130, the first region 110, and the second region 120 may be defined by the presence or absence of sawtooth cg1, cg2 and the cross-sectional area difference.
[0093] In one embodiment, the first region 110 may have a first length L1, and the second region 120 may have a second length L2. In one embodiment, the first length L1 of the first region 110 may be formed to be 1.4 to 3 times the second length L2 of the second region 120, and in one example, the first length L1 may be formed to be 3.5 cm to 4.5 cm, and the first length may be formed to be 1.5 cm to 2.5 cm.
[0094] According to one embodiment of the present invention, the length ratio of the first area 110 to the second area 120 has a predetermined length ratio (1.4:1 to 3:1), so that the lengths of the first area 110 and the second area 120 can be formed in a ratio similar to that of the bridge of the nose and the columella, and a lifting line 100 suitable for the body size of the person undergoing surgery can be formed.
[0095] A plurality of first saw teeth cg1 may be formed in the first region 110, and a plurality of second saw teeth cg2 may be formed in the second region 120. In the present specification, the saw teeth cg1 and cg2 are formed in a manner of protruding from the lifting wire 100, so that when the lifting wire 100 is implanted in the nose of the operated person, it can have the function of being fixed to the internal tissue of the nose of the operated person, and can also be called a "protrusion".
[0096] In one embodiment, the first sawtooth cg1 and the second sawtooth cg2 can be formed in different forms, and the shapes of the first sawtooth cg1 and the second sawtooth cg2 can be formed so that the fixing force of the second sawtooth cg2 is greater than the fixing force of the first sawtooth cg1. Figure 2 As shown, the saw teeth cg1 and cg2 can be formed on the left and right sides of the lifting line 100, although not in Figure 2 However, it should be understood that the front and rear sides of the lifting line 100 (with Figure 2 The visible surface and the back surface when the lifting thread 100 is used as a reference) can also form serrations of a certain shape, and the serrations can be formed at any position on the circumferential surface of the lifting thread 100.
[0097] A plurality of first saw teeth cg1 may be formed by being spaced apart from each other by a first gap d1, and a plurality of second saw teeth cg2 may be formed by being spaced apart from each other by a second gap d2. In one embodiment, the first gap d1 of the first saw teeth cg1 of the lifting wire 100 may be longer than the second gap d2 of the second saw teeth cg2. According to one embodiment of the present invention, the first gap d1 is formed to be longer than the second gap d2, so that the number of saw teeth similar to the columella can be set in the nose bridge longer than the columella, so that the overall fixing force can be maintained.
[0098] Figure 3 : is a diagram showing a lifting line according to an exemplary embodiment of the present invention. In detail, Figure 3 Can be shown viewed from either side Figure 2 The lifting line diagram. Figure 2 Repeated content is omitted.
[0099] Reference Figure 3 , the connection area 130 between the first area 110 and the second area 120 is formed in a bent state so as to have a first angle deg1. In one embodiment, the connection area 130 may be formed by pressurizing the space between the first area 110 and the second area 120 in a bent state, and in another embodiment, the connection area 130 may be formed by heating the space between the first area 110 and the second area 120 and curing in a bent state. In one embodiment, the connection area 130 may be bent in a manner having a predetermined radius of curvature, and as a result, the first area 110 and the second area 120 may have an angle of any one of 60 degrees to 150 degrees.
[0100] In one embodiment, the first angle deg1 may be any angle between 60 and 150. Since the lifting wire 100 is bent at the first angle deg1, the lifting wire 100 can be formed to fit the nose shape of the patient, and the patient's surgical satisfaction and the surgeon's surgical convenience can be improved.
[0101] Figure 3 The side bending of the lifting cord 100 is shown in the figure, but this is only an example, and it should be understood that the lifting cord 100 can be applied to the technical concept of the present invention regardless of the direction in which it is bent based on the connection area 130.
[0102] Figure 4 FIG. 1 is a diagram showing an example of performing surgery using a lifting thread according to an exemplary embodiment of the present invention.
[0103] Reference Figure 4 The nose NS of the person undergoing surgery can be divided into a nose bridge portion 210, a columella portion 220 and a nose tip 230. Through the lifting operation, the first area 110 of the lifting line 100 can be set at the nose bridge portion 210, the second area 120 can be set at the columella portion 220, and the connecting area 130 can be set at the nose tip 230.
[0104] Since the connection region 130 is formed by bending with a predetermined radius of curvature, the first region 110 and the second region 120 may have a predetermined angle, so that the lifting thread 100 can be formed in a manner suitable for the nose NS of the operator.
[0105] In one embodiment, the radius of curvature of the connection area 130 can be changed according to the patient being operated on, so that the shape of the nose tip 230 can be reshaped in a manner suitable for the patient being operated on.
[0106] According to the technical concept of the present disclosure, since the connection area 130 is bent at a predetermined angle, the lifting thread 100 can be prevented from drilling into the internal tissue of the nose NS or returning to protruding outward from the skin, and the surgical satisfaction of the operator can be improved.
[0107] Figure 5 The figure shows a state where a lifting wire according to an exemplary embodiment of the present invention is set in a cannula to perform surgery.
[0108] Reference Figure 5, the lifting line 100 can be implanted into the cannula C during surgery for setting. The cannula C can refer to a medical tool used when penetrating the skin and implanting an internal medical line into the tissue of the person being operated on. When performing a lifting operation, the surgeon can implant the cannula C into the columella, thereby implanting the second region 120 into the columella, and then withdraw the cannula C to set the second region 120 fixed in the columella tissue to the columella through the second serration cg2. Then, the surgeon can implant the cannula C into the bridge of the nose, implant the first region 110 into the bridge of the nose, and then withdraw the cannula C to set the first region 110 fixed in the bridge of the nose tissue to the bridge of the nose through the first serration cg1.
[0109] To this end, in one embodiment, the first area 110 of the lifting thread 100 disposed on the bridge of the nose is implanted with the sleeve C first, and compared with the first area 110, the second area 120 disposed on the columella is implanted with the sleeve C later.
[0110] On the other hand, the connection area 130 may have a second angle deg2 inside the sleeve C. The lifting wire 100 is formed of an elastic material, so after being implanted into the internal tissue of the nose of the operated person, it can be restored to the original position by the inherent elastic force. Figure 3 The first angle deg1 described in .
[0111] According to one embodiment of the present invention, since the elastic force of the lifting wire 100 is discharged from the inside of the sleeve C to the nose of the operator, the angle between the first area 110 and the second area 120 of the lifting wire 100 can be restored to a predetermined angle (for example, 60 degrees to 150 degrees), so that easy surgery can be achieved using the sleeve C.
[0112] Figure 6 : is a diagram showing a lifting line according to an exemplary embodiment of the present invention. In detail, Figure 6 FIG. 1 shows an embodiment in which the connection region 130a is in a mesh-like Ms form. Figure 2 Repeated content is omitted.
[0113] Reference Figure 6 The lifting line 100a may include a first region 110, a second region 120 and a connecting region 130a. In one embodiment, the connecting region 130a may be in a mesh shape, and the mesh shape Ms may have Figure 3 The first angle deg1 described in .
[0114] When the diameter of the central part of the connection area 130a is enlarged, the lifting line 100a can be effectively fixed to the internal tissue of the nose by increasing the adhesion area between the internal tissue of the nose and the lifting line 100a, and the diamond or square collection pattern on the surface of the mesh form Ms can be supported by the nasal cartilage tissue. The connection area 130a is satisfied with the mesh form Ms of the predetermined pattern. In one example, the mesh form Ms can be set as a plurality of filament bundles. If the connection area 130a is in the mesh form Ms, the surface area connected with the cartilage tissue of the nose increases, and the degree of adhesion through foreign body reaction in the body will increase, so the effect will last for a long time, and side effects such as protrusion will be reduced. Not only that, the area in contact with blood or body fluids will also increase, and regeneration will be faster than the time after the lifting line is implanted after surgery.
[0115] In addition, when the connection area 130a is formed into a mesh structure Ms, a space is formed inside, which makes it very easy to introduce physiologically active substances such as hyaluronic acid (HA), polydeoxyribonucleotide (PDRN) and polynucleotide (PN), and can effectively increase the activity of the parts that need the fastest regeneration after the lifting surgery, thereby making it easy to strengthen the tissue.
[0116] Figure 7 : is a diagram showing a lifting line according to an exemplary embodiment of the present invention. In detail, Figure 7 FIG. 2 shows an embodiment in which the connection area 130 b is formed in the form of a spring Spr. Figure 2 Repeated content is omitted.
[0117] Reference Figure 7 The lifting line 100b may include a first region 110, a second region 120, and a connecting region 130b. In one embodiment, the connecting region 130b may be in the form of a spring Spr, and the spring shape Spr may have Figure 3 The first angle deg1 described in .
[0118] The shape of the spring Spr can be formed by a mold or injection molding process, and the shape of the spring Spr can have high elasticity and restoring force. Therefore, when the connecting area 130b is in the shape of the spring Spr, in addition to the first angle deg1 of the lifting line 100b, the nose plastic surgery effect can be improved due to the elasticity of the spring Spr itself, and the first angle deg1 formed by the first area 110 and the second area 120 can be effectively controlled.
[0119] In addition, due to the characteristics of the spring Spr-shaped connection area 130b, the surface area of the internal tissue of the nose and the lifting thread 100b is increased, so the degree of adhesion between the surrounding tissue of the nose and the foreign body reaction in the body can be increased, thereby maintaining the lifting thread implantation effect for a long time and reducing side effects such as protrusion.
[0120] Figure 8 2 is a diagram illustrating a wire lifting method according to an exemplary embodiment of the present invention.
[0121] Reference Figure 8 , the lifting thread 100 may include a first area 110, a second area 120, and a connecting area 130. In one example, the first area 110 may correspond to the nose bridge of the person being operated on, the second area 120 may correspond to the columella of the person being operated on, and the connecting area 130 may correspond to the nose tip of the person being operated on. The connecting area 130, the first area 110, and the second area 120 may be defined according to the presence or absence of sawtooth cg1, cg2 and the cross-sectional area difference.
[0122] A lifting thread is a thread made for the purpose of surgical operation, especially for rhinoplasty. It is a thread made by a lifting operation for raising the bridge of the nose or the angle of the nose tip. It may be called a lifting thread or other names.
[0123] A plurality of first saw teeth cg1 may be formed in the first region 110, and a plurality of second saw teeth cg2 may be formed in the second region 120. In the present specification, the saw teeth cg1 and cg2 are formed in a manner of protruding from the lifting wire 100, so that when the lifting wire 100 is implanted in the nose of the person undergoing surgery, it can have the function of being fixed to the internal tissue of the nose of the person undergoing surgery, and can also be referred to as a "protrusion". In one embodiment, the first saw tooth cg1 and the second saw tooth cg2 can be constructed in different forms, and the shapes of the first saw tooth cg1 and the second saw tooth cg2 can be formed so that the fixing force of the second saw tooth cg2 is greater than the fixing force of the first saw tooth cg1. Figure 8 As shown, the saw teeth cg1 and cg2 can be formed on the left and right sides of the lifting line 100, and although not Figure 8 However, it should be understood that the front and rear sides of the lifting line 100 (with Figure 8 The visible surface and the back surface thereof as a reference may also form serrations of a certain shape, and the serrations may be formed at any position on the circumferential surface of the pulling thread 100.
[0124] The connection region 130 may be formed thicker than the first region 110 and the second region 120. In this specification, the thickness, cross-sectional area, and cross-sectional diameter of the first region 110 and the second region 120 may refer to values excluding sawtooth cg1 and cg2 formed in the first region 110 and the second region 120.
[0125] In one embodiment, the cross-sectional area at any position in the connection region 130 may be formed to be wider than the cross-sectional areas of the first region 110 and the second region 120. In one embodiment, the diameter of the cross section at any position in the connection region 130 may be formed to be longer than the diameter of the cross section of the first region 110 and the second region 120. The above cross section may refer to a cross section obtained by cutting the connection region 130 perpendicular to the length direction of the lifting thread 100. In one embodiment, the connection region 130 may be formed to make the cross section increasingly thicker from the first region 110 to the second region 120.
[0126] According to one embodiment of the present invention, the connection area 130 is formed to be thicker than the areas 110 and 120 provided on the columella and the bridge of the nose, thereby reducing the pressure applied to the tissue or cartilage existing on the bridge of the nose, thereby reducing the pain of the person undergoing surgery, preventing deformation or damage caused by the surgery, and increasing the surgical effect.
[0127] In one embodiment, the cross-sections of the first region 110 , the second region 120 , and the connection region 130 may be elliptical in shape, and the maximum diameter in this specification may refer to the major axis of the ellipse.
[0128] In one embodiment, the first region 110 may be formed to have a first length L1, and the second region 120 may be formed to have a second length L2. In one embodiment, the first length L1 of the first region 110 may be formed to be 1.4 to 3 times the second length L2 of the second region 120. In one example, the first length L1 may be formed to be 3.5 cm to 4.5 cm, and the first length may be formed to be 1.5 cm to 2.5 cm. The first region 110 and the second region 120 have the above-mentioned length ratio and length range. The first region 110 may be appropriately set at the bridge of the nose during surgery, and the second region 120 may be appropriately set at the columella during surgery.
[0129] Fig. 9 : is a diagram showing a lifting line according to an exemplary embodiment of the present invention. In detail, Fig. 9 To show in detail Figure 8 FIG. 1 is a diagram of the connection area 130 described in FIG.
[0130] Reference Fig. 9, the connection region 130 may include a first section AA' cut along the length direction, a second section BB' cut perpendicularly along the length direction and close to the first region 110, and a third section CC' cut perpendicularly along the length direction and close to the second region 120. In one example, the connection region 130 may be connected to the first region 110 at the second section BB', and may be connected to the second region 120 at the third section CC'.
[0131] The thickness of the connection region 130 may be thinner as it approaches the second cross section BB', and may be thicker as it approaches the third cross section CC'. In addition, the cross-sectional area of the connection region 130 may be narrower as it approaches the second cross section BB', and may be wider as it approaches the third cross section CC'. In addition, the maximum diameter of the cross section of the connection region 130 may be shorter as it approaches the second cross section BB', and may be longer as it approaches the third cross section CC'.
[0132] In one embodiment, the diameter of the connecting area 130 may gradually increase from the second section BB' connected to the first area 110 to the third section CC' connected to the second area 120, so that when the connecting area 130 is set on the nose of the operated person, the thicker part can be accurately set between the cartilages, thereby reducing the pressure applied to the cartilage (for example, the alar cartilage) located on the nose of the operated person.
[0133] Fig.10 is a cross-sectional view of a lifting wire according to an exemplary embodiment of the present invention. Fig.10 Shown cutting along the A-A' direction Fig. 9 A cross section of the connection region 130 .
[0134] Reference Fig. 9 and Fig.10 , showing a first cross section A-A' cutting the connection region 130 along the A-A' direction as the length direction. The first cross section A-A' may include a first side A close to the first region 110 and a second side A' close to the second region 120, the first side A may have a first length d1, and the second side A' may have a second length d2. In one embodiment, the first length d1 may be shorter than the second length d2. Therefore, the first cross section A-A' may have a trapezoidal shape having a top side as the first side A and a bottom side as the second side A'.
[0135] Fig.11a and Fig.11b is a cross-sectional view of a lifting wire according to an exemplary embodiment of the present invention. Fig.11a Shown cutting along the B-B' direction Fig. 9 A cross section of the connection region 130, Fig.11b Shows cutting along the C-C' direction Fig. 9 A cross section of the connection region 130 .
[0136] Reference Fig.11a , showing a second cross section BB' cut along a direction BB' perpendicular to the length direction in the connection region 130 near the first region 110. In one embodiment, the second cross section BB' may be elliptical, and the major axis (or maximum diameter) may be formed as a third length d3.
[0137] Reference Fig.11b , showing a third cross section CC' cut along a direction CC' perpendicular to the length direction in the connection region 130 near the second region 110. In one embodiment, the third cross section CC' may be formed as an ellipse, and the major axis (or maximum diameter) may be formed as a fourth length d4, which may be longer than the third length d3.
[0138] According to one embodiment of the present invention, the maximum diameter of the second cross section BB' near the first region 110 may be formed to be shorter than the maximum diameter of the third cross section CC' near the second region 120. Therefore, when the connection region 130 is disposed on the nose of the operated person, the thicker portion may be accurately disposed between the cartilages, thereby reducing the pressure applied to the cartilages and tissues located on the nose of the operated person.
[0139] Figure 12 to Figure 14 2 is an anatomical diagram showing an example of use of a lifting thread according to an exemplary embodiment of the present invention. Fig.12 1 is an anatomical diagram showing an example of setting a first area 110 of a lifting wire 100 in a nose bridge portion of a patient's nose N in a manner that allows the nose bridge to be visualized (for example, the patient's nose is viewed from the front). Fig.13 1 is an anatomical diagram showing an example of setting the second area 120 of the lifting wire 100 in the columella part of the nose N of the patient, in which the columella is observed in a manner that the columella is visible (for example, the nose of the patient is observed from below). Fig.14 1 is an anatomical diagram showing the nose N of a person undergoing surgery as viewed from the side. Fig.12 and Fig.13 Although there is no separate diagram, in fact, Fig.12 The first region 110 and Fig.13 The second regions 120 shown in FIG. 1 may be connected via a connecting region 130 .
[0140] Reference Figure 12 to Figure 14 Since the first area 110 is disposed in the internal tissue of the bridge of the nose, the volume and height of the bridge of the nose may be deformed. Since the second area 120 is disposed in the columella portion, the columella portion of the nose is supported to make it upright, thereby performing nose plastic surgery to increase the height of the columella and the nasolabial angle.
[0141] At the same time, the connection area 130 will be located at the tip of the nose, where there is cartilage Ca (e.g., alar cartilage), and the cartilage Ca may include an opening at the center. Since the first area 110 and the second area 120 are supported by the saw teeth cg1 and cg2, the connection area 130 may be subjected to tensile force from both sides. Due to the curved shape of the lifting wire 100, the connection area 130 may form a quintessential force F in the direction of the opening of the cartilage Ca. These quintessential forces F may act on the center of the cartilage Ca, deforming and damaging the structure between the two cartilages, which may cause pain to the person being operated on and inaccuracy in the operation.
[0142] The connection area 130 according to the technical idea of the present invention may have a relatively thick thickness, and therefore, the contact area between the connection area 130 and the cartilage Ca may be increased. The pressure on the person being operated on is equivalent to the value of force divided by the surface area (P=F / A), so the contact area is wider, thereby reducing the pressure on the person being operated on. Therefore, when a nose lift operation is performed using the lifting thread according to the technical idea of the present invention, the pressure on the opening of the cartilage Ca is reduced, thereby alleviating the pain of the person being operated on, and since the connection area 130 is thicker, the lifting thread 100 cannot easily drill into the opening of the cartilage Ca, thereby minimizing damage to the cartilage Ca. In addition, since the nose tip is substantially supported, the tip plastic surgery effect can be improved.
[0143] In addition, according to one embodiment of the present invention, the connection area 130 is thicker as it is closer to the second area 120, so the lifting thread 100 can be formed so that the thicker part of the connection area 130 is accurately disposed at the opening of the cartilage Ca, and the pressure reduction effect on the opening can be maximized. In addition, since the connection area 130 is thicker as it is closer to the second area 120, the support force for forming a relatively short second area 120 can be increased.
[0144] Figure 12 to Figure 14 An example is shown in which the technical effect of the present invention is achieved due to the thicker connecting area 130, but this is only an example. Examples in which the connecting area 130 is formed in a mesh form or in a core spring form may also be applicable to the technical idea of the present invention. This is described in detail in Korean Application No. 10-2021-0085757 (lifting thread for nose plastic surgery using a core spring) and Korean Application No. 10-2021-0085758 (lifting thread for nose plastic surgery using a mesh). The contents covered by the patent applications are introduced into this specification by reference.
[0145] Figures 15a to 15c FIG. 1 is a diagram showing a connection area according to an exemplary embodiment of the present invention. Figures 1 to 14 Duplicate content.
[0146] Reference Fig.15a In the connection area 130a, the side close to the first area 110 may gradually become thicker so as to have a smooth slope, whereas the side close to the second area 120 may be formed into a spoon shape that becomes sharply thicker. In one embodiment, since the connection area 130a is in the spoon shape, the contact area of the connection area 130a with respect to the portion located at the opening of the cartilage increases, thereby minimizing damage to the cartilage.
[0147] Reference Fig.15b , the connection area 130b may be in a wavy shape, and the wavy shape is formed by a plurality of thick portions and thin portions therebetween. In one embodiment, since the connection area 130b is in a wavy shape, only the portion where the surface area needs to be increased is made thicker. In addition, when bending, the thin portion is guided to bend so that the lifting wire is set on the nose, thereby minimizing the essential force applied to the nose of the person being operated on. Fig.15b In the figure, an example including two thick portions is shown, but this is only an example, and an example including more than two thick portions in the connection area 130b may also be applicable to the technical idea of the present invention.
[0148] Reference Fig.15c The connection area 130c may be formed into a strip having the same overall thickness. In one embodiment, the connection area 130c is formed into a strip thicker than the first area 110 and the second area 120, so that the manufacturing process of the lifting thread 100 can be facilitated.
[0149] Fig.16 2 is a diagram illustrating a wire lifting method according to an exemplary embodiment of the present invention.
[0150] Reference Fig.16 The lifting thread 10 may include a first lifting portion 100 provided at the nose bridge portion of the operated person and a second lifting portion 200 provided at the columella portion of the operated person. The first lifting portion 100 and the second lifting portion 200 may be distinguished by a central axis CL. The lifting thread is a thread made for the purpose of surgical operation, especially for rhinoplasty, and is a thread made by a lifting operation for raising the nose bridge or raising the nose tip angle, and may be called a lifting thread or other names.
[0151] The first lifting portion 100 may include at least one first serration 110, and the second lifting portion 200 may include at least one second serration 210. In the present specification, the serration is formed in a manner of protruding from the lifting wire 10, so that when the lifting wire 10 is implanted in the nose of the operated person, it can have the function of being fixed to the internal tissue of the nose of the operated person, and can also be called a "protrusion". Fig.16 As shown, the saw teeth can be formed on the left and right sides of the lifting line 10, and can also be formed on the front and back sides of the lifting line 10 (with Fig.16The serrations of a certain shape are formed on the surface (the visible surface and the back surface) of the lifting wire 10 as a reference. It should be understood that the serrations can be formed at any position on the circumferential surface of the lifting wire 10.
[0152] The cross section of the first sawtooth 110 of the first lifting part 100 may be formed in the shape of a gentle triangle, wherein the gentle triangle has the side in contact with the length direction d1 of the lifting line 10 as the bottom side, and the first side 111 and the second side 112 as the top sides. The cross section of the first sawtooth 110 may include a 1-1 point A1 intersecting the first side 111 on one side of the length direction d1, a 1-3 point A3 intersecting the second side 112 on the other side of the length direction d1, and may also include a 1-2 point A2 intersecting the first side 111 and the second side 112.
[0153] The cross section of the second sawtooth 210 of the second lifting portion 200 may be formed in the shape of a pointed triangle, wherein the pointed triangle has the side in contact with the length direction d1 of the lifting line 10 as the bottom side, and the third side 211 and the fourth side 212 as the top sides. The cross section of the second sawtooth 210 may include a 2-1 point B1 intersecting the third side 211 on one side of the length direction d1, a 2-3 point B3 intersecting the fourth side 212 on the other side of the length direction d1, and may also include a 2-2 point B2 intersecting the third side 211 and the fourth side 212.
[0154] According to an embodiment of the present invention, the first side 111 and the second side 112 of the first sawtooth 110 can be formed in a direction extending leftward and rightward based on the 1-2 point A2. Therefore, the first sawtooth 110 is relatively close to the direction extending from one side to the other side of the length direction d1 ( Fig.16 In the example of the left-to-right direction) and from the other side of the length direction d1 to one side ( Fig.16 In the example, both directions from right to left can have a smooth inclination. According to the technical concept of the present invention, the first sawtooth 110 has an acute triangle shape with a smooth inclination relative to both directions, so it can be easily discharged when discharged from the sleeve in the reverse direction. Fig. 20 Detailed description.
[0155] In addition, the third side 211 and the fourth side 212 of the second sawtooth 210 can be formed to be oriented toward the other side (at the 2-2 point B2) with respect to the 2-2 point B2. Fig.16 In the example, the direction of progress from right to left) is the direction of progress. Therefore, the second sawtooth 210 may be stuck due to the 2-2 point B2 or the 3-2 point C2 in the opposite direction of the progress. According to one embodiment of the present invention, the second sawtooth 210 is formed in a pointed triangular shape that can cause a stuck phenomenon in the opposite direction of the progress, thereby improving the fixing force in the lifting operation. Fig.19Described in detail in.
[0156] In order to form the first sawtooth 110 in the shape of an acute triangle, the 1-4 point A2-1 at which a vertical line descending from the 1-2 point A2 of the first sawtooth 110 along the width direction dw toward the central axis CC intersects with the horizontal line of the pull-up cord 10 may be located between the 1-1 point A1 and the 1-3 point A3. In addition, the first angle θ1 between the second side 112 of the first sawtooth 110 and the horizontal line of the pull-up cord 10 may form an obtuse angle. The first side 111 may form an acute angle with respect to the same direction of the horizontal line.
[0157] In order to form the second sawtooth 210 in a pointed triangle shape, the 2-4 point B2-1 at which a vertical line descending from the 2-2 point B2 of the second sawtooth 210 along the width direction dw toward the central axis CC intersects with the horizontal line of the pulling wire 10 may be located on one side of the 2-1 point B1 and the 2-3 point B3 (at Fig.16 In addition, the second angle θ2 between the third side 211 of the second sawtooth 210 and the horizontal line of the lifting thread 10 may form an acute angle. The fourth side 212 may form an acute angle with respect to the same direction of the horizontal line.
[0158] In one embodiment, the height of the first sawtooth 110 (e.g., the distance from the 1-2 point A2 to the 1-4 point A4) may be shorter than the height of the second sawtooth 210 (e.g., the distance from the 2-2 point B2 to the 2-4 point (B4)). Therefore, as described later, the first sawtooth 110 may be easily ejected from the sleeve, and the second sawtooth 210 may increase the fixing force to the nose.
[0159] In addition, the technical concept of the present disclosure can also be applied to the embodiment in which the second serration 210 is provided on the first lifting portion 100, the first serration 110 is provided on the second lifting portion 100, and the first serration 110 is provided on the columella and the second serration 210 is provided on the bridge of the nose.
[0160] Fig.17 : is a diagram showing a lifting line according to an exemplary embodiment of the present invention. In detail, Fig.17 Can show Fig.16 A side view of the lifting line 10.
[0161] Reference Fig.17 The first serration 110 and the second serration 210 of the lifting thread 10 may form protrusions on the side surfaces. Fig.17 The figure shows that a triangular or conical protrusion is formed on the side of each first sawtooth 110 and the second sawtooth 210, but this is only one embodiment. As long as the protrusion imparts additional fixing force, it can be formed on the side of the first sawtooth 110 and the second sawtooth 210 in any shape. In one example, Fig.16The shape of each of the first serrations 110 and the second serrations 210 shown in FIG. 1 (eg, a gentle triangle or a pointed triangle) may also be formed on the side.
[0162] Fig.16 and Fig.17 FIG. 1 shows that the plane and side shapes of the first saw tooth 110 and the second saw tooth 210 are different, but this is only an example. The first saw tooth 110 and the second saw tooth 210 may also be formed as circular rotating bodies (eg, cones) having the same plane and side shapes.
[0163] Fig.18 : is a diagram showing an example of use of a lifting wire according to an exemplary embodiment of the present invention. In detail, Fig.18 The structure in which the lifting wire 10 enters the sleeve 300 is shown.
[0164] Reference Fig.18 The cannula 300 is a needle with a rounded end and a cannula hole 310 in the middle, and is composed of a structure into which the lifting thread 10 enters. The lifting operation can be performed in the following manner, that is, the first serration 110 and the second serration 210 of the lifting thread 10 are fixed to the skin tissue through the discharge port 310, and the cannula 300 is separated from the skin tissue. In one embodiment, after the operation on the columella, the operation on the bridge of the nose can be performed, so the first serration 110 included in the first lifting part 100 is first implanted in the cannula 300, and the second serration 210 included in the second lifting part 200 can be implanted later.
[0165] It should be understood that for ease of description and illustration of use, Figures 18 to 20 The size of the sleeve 300 shown in the figure may be larger than that of a conventional sleeve 300, and the number of saw teeth 110, 210 included in the lifting thread 10 may be arbitrarily shown and may be different from the actual number.
[0166] Fig.19 : is a diagram showing an example of use of a lifting wire according to an exemplary embodiment of the present invention. In detail, Fig.19 An example is shown in which the lifting wire 10 enters the columella of the person being operated on.
[0167] Reference Fig.16 and Fig.19 , the surgeon implants the cannula 300 with the lifting wire 10 in the columella of the patient, and can retract the implanted cannula 300 in the opposite direction of the implantation direction. According to one embodiment of the present invention, due to the second angle θ2 ( Fig.16 ) forms an acute angle, so the 2-2 point B2 ( Fig.16) can firmly fix the second lifting portion 200 on the columella of the nose. During the recovery process of the sleeve 300, the second lifting portion 200 can be firmly set on the columella of the person undergoing surgery through the discharge port 310. The fourth side 212 ( Fig.16 ) has a gentle inclination, and during the recovery process of the sleeve 300, the second pulling portion 200 can be easily discharged from the discharge port 310.
[0168] Fig. 20 : is a diagram showing an example of use of a lifting wire according to an exemplary embodiment of the present invention. In detail, Fig. 20 An example is shown where the lifting wire 10 enters the nose bridge of the person being operated on.
[0169] Reference Fig.16 and Fig. 20 In part (a), the second lifting portion 200 of the lifting wire 10 is arranged behind the columella of the operator, and the operator can change the direction of the sleeve 300 so that the sleeve 300 enters the bridge of the nose. At this time, the second sawtooth 210 is firmly fixed to the columella, so when the sleeve 300 enters the bridge of the nose, the lifting wire 10 can also be easily discharged from the sleeve 300.
[0170] Reference Fig.16 and Fig. 20 In part (b), the surgeon implants the cannula 300 into the bridge of the nose, so that the first lifting portion 100 can be set on the bridge of the nose. At this time, the first lifting portion 100 must be set in the opposite direction to the direction of the cannula 300. The first lifting portion 100 can only be discharged from the outlet 210 in a bent state, and a jamming phenomenon will inevitably occur between the saw teeth of the first lifting portion 100 and the outlet 310.

[0181] Fig.25 : is a diagram showing a lifting line according to an exemplary embodiment of the present invention. In detail, Fig.25 The first lifting portion 100 includes the third sawtooth 120. Fig.16 Duplicate content.
[0182] Reference Fig.25The first lifting portion 100 may include a third sawtooth 120 disposed at the end in the length direction d1 and at least one first sawtooth 110 disposed in sequence further inside the third sawtooth 120. In one embodiment, the cross section of the third sawtooth 120 may be formed in a shape similar to that of the second sawtooth 210.
[0183] The cross section of the third sawtooth 120 of the first lifting portion 100 may be formed in the shape of a gentle triangle, the gentle triangle having the side in contact with the length direction d1 of the lifting line 10 as the bottom side, and the fifth side 121 and the sixth side 122 as the top sides. The cross section of the first sawtooth 110 may include a 1-1 point A1 intersecting the first side 111 on one side of the length direction d1, a 1-3 point A3 intersecting the second side 112 on the other side of the length direction d1, and may also include a 1-2 point A2 intersecting the first side 111 and the second side 112. In one example, the fifth side 121 and the sixth side 122 may be symmetrical.
[0184] The cross section of the third sawtooth 120 of the first lifting portion 100 may be formed in the shape of a pointed triangle, the pointed triangle having the side in contact with the length direction d1 of the lifting line 10 as the base, and the fifth side 121 and the sixth side 122 as the top. The cross section of the third sawtooth 120 may include a 3-1 point C1 intersecting the fifth side 121 on one side of the length direction d1, a 3-3 point C3 intersecting the sixth side 122 on the other side of the length direction d1, and may also include a 3-2 point C2 intersecting the fifth side 121 and the sixth side 122.
[0185] In addition, the fifth side 121 and the sixth side 122 of the third sawtooth 120 can be formed to be oriented in a direction to one side (at Fig.16 In the example, the direction of progress from right to left) is the direction of progress. Therefore, the third sawtooth 120 may be stuck due to the 3-2 point C2 in the opposite direction of the progress direction. According to one embodiment of the present invention, the third sawtooth 120 is formed in a pointed triangular shape that can cause a stuck phenomenon in the opposite direction of the progress direction, thereby improving the fixing force in the lifting operation.
[0186] In order to form the third sawtooth 120 in a pointed triangle shape, the 3-4 point C2-1 at which a vertical line descending from the 3-2 point C2 of the third sawtooth 120 along the width direction dw toward the central axis CC intersects with the horizontal line of the pulling line 10 may be located on the other side of the 3-1 point C1 and the 3-3 point C3 (at Fig.16In the example of the right side). In addition, the third angle θ3 between the sixth side 122 of the third sawtooth 120 and the horizontal line of the lifting line 10 may form an acute angle. The fifth side 121 may form an acute angle with respect to the same direction of the horizontal line. Since the third angle θ3 of the third sawtooth 120 forms an acute angle, the sharp shape of the 3-2 point c2 of the third sawtooth 120 can firmly fix the first lifting part 100 on the bridge of the nose, and the lifting line 10 is firmly set on the nose of the operator as a whole.
[0187] In one embodiment, the height of the first sawtooth 110 (e.g., the distance from the 1-2 point A2 to the 1-4 point A4) may be shorter than the height of the third sawtooth 120 (e.g., the distance from the 3-2 point C2 to the 3-4 point C4). Therefore, as described later, the first sawtooth 110 may be easily ejected from the sleeve, and the second sawtooth 210 and the third sawtooth 120 may increase the fixing force to the nose.
[0188] Fig.25 An example in which one third sawtooth 120 is included in the first lifting portion 100 is shown, but this is only an example, and in another example, more than one third sawtooth 120 may be included in the first lifting portion 100. In addition, it should be understood that the technical concept of the present invention can also be applied to an example in which only the first sawtooth 110 but no third sawtooth 120 is included in the first lifting portion 100.
[0189] Fig.26 2 is a diagram illustrating a wire lifting method according to an exemplary embodiment of the present invention.
[0190] Reference Fig.26 The lifting thread 10 may include a first lifting portion 100 provided at the nose bridge portion of the operated person and a second lifting portion 200 provided at the columella portion of the operated person. The first lifting portion 100 and the second lifting portion 200 may be distinguished by a central axis CL. The lifting thread is a thread made for the purpose of surgical operation, especially for rhinoplasty, and is a thread made by a lifting operation for raising the nose bridge or raising the nose tip angle, and may be called a lifting thread or other names.
[0191] The first lifting portion 100 may include at least one negative angle sawtooth 110, and the second lifting portion 200 may include at least one positive angle sawtooth 210. In the present specification, the sawtooth is formed in a manner of being implanted or protruding from the lifting wire 10, so that when the lifting wire 10 is implanted in the nose of the operated person, it can have the function of being fixed to the internal tissue of the nose of the operated person, and can also be called a "protrusion". Fig.26 As shown, the saw teeth can be formed on the left and right sides of the lifting line 10, and can also be formed on the front and back sides of the lifting line 10 (with Fig.26The serrations of a certain shape are formed on the surface (the visible surface and the back surface) of the lifting wire 10 as a reference. It should be understood that the serrations can be formed at any position on the circumferential surface of the lifting wire 10.
[0192] In the present specification, the negative-angle serrations are not formed as protruding protrusions, but are formed as a curve in a shape implanted inward from the surface of the lifting wire 10, thereby meaning a serration that induces a locking phenomenon with the internal tissue of the nose of the operated person, and the positive-angle serrations are formed as a curve in a shape protruding outward from the surface of the lifting wire 10, thereby meaning a serration that induces a locking phenomenon in the internal tissue of the nose of the operated person.
[0193] According to the technical concept of the present invention, the first lifting portion 100 includes negative angle serrations 110, and the thickness tn becomes thicker than that of the positive angle serrations 210, so the volume of the nose bridge of the operator increases, thereby increasing the operator's satisfaction with the operation.
[0194] The cross section of the negative angle serration 110 of the first lifting portion 100 may be composed of a first side 111 and a second side 112 implanted inwardly with the surface SF parallel to the length direction d1 of the lifting line 10 as a reference. According to one embodiment of the present disclosure, the first angle θ1 between the first side 111 and the surface SF may be an obtuse angle or a right angle, and the second angle θ2 between the second side 112 and the surface SF may be an obtuse angle or a right angle. Therefore, the first side 111 and the second side 112 may form a gentle triangle with the extension line of the surface SF, and the sleeve may be easily discharged when it is discharged in the reverse direction from the first lifting portion 100. Fig.29 etc. for detailed description.
[0195] In the present specification, the cross-sectional shape of the negative-angle serration 110 may mean a spatial shape produced by implanting inward from the surface SF of the lifting thread 10 (for example, a triangle formed by the 1-1 point A1, the 1-2 point A2, and the 1-3 point A3), and the cross-sectional shape of the positive-angle serration 210 may mean a shape of a protrusion produced by protruding outward from the surface SF of the lifting thread 10 (for example, a triangle formed by the 2-1 point B1, the 2-2 point B2, and the 2-3 point B3).
[0196] The cross section of the negative angle sawtooth 110 may include a 1-1 point A1 intersecting the first side 111 on one side of the length direction d1 and a 1-3 point A3 intersecting the second side 112 on the other side of the length direction d1, and may also include a 1-2 point A2 intersecting the first side 111 and the second side 112.
[0197] The cross section of the positive angle sawtooth 210 of the second lifting part 200 may be formed in the shape of a pointed triangle, wherein the pointed triangle has the side in contact with the length direction d1 of the lifting line 10 as the bottom side, and the third side 211 and the fourth side 212 as the top sides. The cross section of the positive angle sawtooth 210 may include a 2-1 point B1 intersecting the third side 211 on one side of the length direction d1, a 2-3 point B3 intersecting the fourth side 212 on the other side of the length direction d1, and may also include a 2-2 point B2 intersecting the third side 211 and the fourth side 212.
[0198] According to an embodiment of the present invention, the first side 111 and the second side 112 of the negative angle sawtooth 110 can be formed in a direction extending leftward and rightward based on the 1-2 point A2, so the negative angle sawtooth 110 is relatively perpendicular to the direction extending from one side to the other side of the length direction d1 (in Fig.26 In the example of the left-to-right direction) and the direction from the other side of the length direction d1 to the one side (in Fig.26 In the example of the present invention, the negative angle sawtooth 110 has a smooth inclination in both directions. According to the technical concept of the present invention, the negative angle sawtooth 110 has a gentle triangular shape with a smooth inclination in both directions, so it can be easily discharged when discharged from the sleeve in the reverse direction. Fig.29 Described in detail in.
[0199] In addition, the third side 211 and the fourth side 212 of the positive angle sawtooth 210 can be formed to be oriented toward the other side (at the 2-2 point B2) with respect to the 2-2 point B2. Fig.26 In the example, the direction of progress from right to left) is the direction of progress. Therefore, the positive angle sawtooth 210 may be stuck due to the 2-2 point B2 or the 3-2 point C2 in the opposite direction of the progress direction. According to one embodiment of the present invention, the positive angle sawtooth 210 is formed into a sharp triangle shape that can cause a stuck phenomenon in the opposite direction of the progress direction, thereby improving the fixing force in the lifting operation. Fig.28 Described in detail in.
[0200] In order to form the negative angle serration 110 in a gentle triangular shape, the 1-4 point A2-1 where a vertical line descending from the 1-2 point A2 of the negative angle serration 110 along the width direction dw intersects with an extension line of the surface SF of the pulling thread 10 may be located between the 1-1 point A1 and the 1-3 point A3.
[0201] In order to form the right-angle sawtooth 210 in a pointed triangle shape, the 2-4 point B2-1 at which a vertical line descending from the 2-2 point B2 of the right-angle sawtooth 210 along the width direction dw toward the central axis intersects with the horizontal line of the pulling line 10 may be located on one side of the 2-1 point B1 and the 2-3 point B3 ( Fig.26In addition, the third angle θ3 between the third side 211 of the positive angle sawtooth 210 and the horizontal line of the lifting line 10 may form an acute angle. The fourth side 212 may form an acute angle with respect to the same direction of the horizontal line.
[0202] In addition, the positive-angle serrations 210 are provided on the first lifting portion 100, and the negative-angle serrations 110 are provided on the second lifting portion 100, so that the negative-angle serrations 110 are provided on the columella and the positive-angle serrations 210 are provided on the bridge of the nose. The technical idea of the present disclosure can also be applied in the embodiment.
[0203] Fig. 27 : is a diagram showing an example of use of a lifting wire according to an exemplary embodiment of the present invention. In detail, Fig. 27 The structure in which the lifting wire 10 enters the sleeve 300 is shown.
[0204] Reference Fig. 27 The cannula 300 is a needle with a rounded end and a cannula hole 310 in the middle, and is composed of a structure into which the lifting thread 10 enters. The lifting operation can be performed in the following manner, that is, the negative angle serrations 110 and the positive angle serrations 210 of the lifting thread 10 are fixed to the skin tissue through the discharge port 310, and the cannula 300 is separated from the skin tissue. In one embodiment, after the operation on the columella, the operation on the bridge of the nose can be performed, so the negative angle serrations 110 included in the first lifting part 100 are first implanted in the cannula 300, and the positive angle serrations 210 included in the second lifting part 200 can be implanted later.
[0205] It should be understood that for ease of description and illustration of use, Figure 27 to Figure 29 The size of the sleeve 300 shown may be larger than the size of a conventional sleeve 300, and the number of saw teeth 110, 210 included in the lifting thread 10 may be arbitrarily shown and may be different from the actual number.
[0206] Fig.28 : is a diagram showing an example of use of a lifting wire according to an exemplary embodiment of the present invention. In detail, Fig.28 An example is shown in which the lifting wire 10 enters the columella of the person being operated on.
[0207] Reference Fig.26 and Fig.28 , the surgeon implants the cannula 300 with the lifting wire 10 inside into the columella of the patient, and the implanted cannula 300 can be recovered in the opposite direction of the implantation direction. According to one embodiment of the present invention, the third triangle θ3 ( Fig.26 ) forms an acute angle, so the 2-2 point B2 ( Fig.26) can firmly fix the second lifting portion 200 on the columella of the nose. During the recovery process of the sleeve 300, the second lifting portion 200 can be firmly set on the columella of the person undergoing surgery through the discharge port 310. The fourth side 212 ( Fig.26 ) has a gentle inclination, and during the recovery process of the sleeve 300, the second pulling portion 200 can be easily discharged from the discharge port 310.

At this time, the positive angle serrations 210 are firmly fixed to the columella, so when the cannula 300 enters the bridge of the nose, the lifting wire 10 can also be easily discharged from the cannula 300.
[0210] Reference Fig.26 and Fig.29 In part (b), the surgeon implants the cannula 300 into the bridge of the nose, so that the first lifting part 100 can be set on the bridge of the nose. At this time, the first lifting part 100 must be set in the opposite direction to the direction of the cannula 300. The first lifting part 100 can only be discharged from the outlet 210 in a bent state, and a jamming phenomenon will inevitably occur between the saw teeth of the first lifting part 100 and the outlet 310. According to one embodiment of the present invention, since the first angle θ1 ( Fig.26 ) forms an obtuse angle, so when the positive angle sawtooth 210 is discharged from the sleeve 300, the first pulling portion 100 can be pulled along the gentle edge of the positive angle sawtooth 210 (for example, the second edge 112 ( Fig.26 )) is discharged from the discharge port 310, so the negative angle serrations 110 can be easily discharged from the sleeve 300 even in the bending direction.
[0211] Reference Fig.26 and Fig.29 In part (c), the surgeon uses the cannula 300 to complete the installation up to the end of the lifting wire 10, and the implanted cannula 300 can be recovered in the opposite direction of the implantation direction. At this time, since the lifting wire 10 is composed of the negative angle sawtooth 110, the thickness of the first lifting part 100 provided on the patient may become thicker, so the volume of the patient's nose bridge increases, thereby increasing the patient's satisfaction with the surgery.

[0248] Reference Fig.38 The nose NS of the person undergoing surgery can be divided into a nose bridge portion P1 and a columella portion P2.

[0260] Figures 40a to 40c The example of using various saw teeth in the first extension part 300 is shown, but the technical concept of the present invention is not limited thereto. The first extension part 300 uses various types of saw teeth according to the sub-extension part, so it is naturally applicable to various embodiments that give a sense of volume to the bridge of the nose.

For this reason, the cross section of the gentle negative angle sawtooth 310g may be formed by a first side 311g and a second side 312g implanted inwardly with the surface SF of the lifting wire 10 as a reference. According to one embodiment of the present invention, the first angle θ1 between the first side 311g and the surface SF may be an obtuse angle or a right angle, and the second angle θ2 between the second side 312g and the surface SF may be an obtuse angle or a right angle.

[0263] In the present specification, the cross-sectional shape of the gentle negative angle sawtooth 310g may mean a spatial shape (for example, a triangle formed by the 1-1 point El, the 1-2 point E2, and the 1-3 point E3) generated by implanting from the surface SF of the lifting thread 10 inward. The cross-sectional shape of the gentle negative angle sawtooth 310g may include the 1-1 point El where the surface SF intersects the first side 311g, the 1-3 point A3 where the surface SF intersects the second side 312g, and may also include the 1-2 point A2 where the first side 311g intersects the second side 312g.

According to the technical concept of the present invention, the gentle negative angle sawtooth 310g has a gentle triangular shape with a smooth inclination relative to both directions, so that the first extension portion 300g using it can also be easily discharged when discharged from the sleeve in the reverse direction.
[0265] Reference Fig.41b The first extension portion 300h may only include the gentle negative angle saw teeth 310h. Therefore, the sleeve of the first extension portion 300h can be easily discharged to the greatest extent, and the difficulty of the process can be reduced.

[0268] To this end, the cross section of the pointed negative angle sawtooth 310i can be formed by the first side 311i and the second side 312i implanted inwardly based on the surface of the lifting thread 10 as a reference, and the third side 313i between the first side 311i and the second side 312i. According to one embodiment of the present invention, the first angle θ1 between the first side 311i and the surface can be an acute angle, and the second angle θ2 between the second side 312g and the surface SF can be an acute angle. Therefore, the first side 311g, the second side 312g and the third side 313i can form a diamond shape with a narrow upper part with the extension line of the surface, and the intersection of the first side 311i and the second side 312i with the surface is sharp, so that the tissue can be maximized during the operation.
[0269] Reference Figure 42b The first extension portion 300j may only include the sharp negative angle serrations 310j. Therefore, the locking phenomenon of the skin tissue of the first extension portion 300i can be maximized, and the fixing force can be enhanced.
