Description

Surgical Instruments for Skin Tissue Lift

The present invention relates to a surgical tool for skin tissue lifting, and more particularly, to a surgical tool for skin tissue lifting that enables to perform skin tissue lifting that can stably maintain a state of lifting the skin tissue drooping downward. In particular, the present invention relates to a surgical tool for facial elevation that enables to perform facial elevation that can maintain a stable state of lifting the face.

The cause of facial aging is the aging of biological tissues, which reduces elasticity, retaining ligaments, which act as pillars while supporting structures in the skin as they age, gradually weaken skin, fat, and muscles by their own weight. That is, sag caused by gravity. This phenomenon is found in the hips, chest, and neck as well as the face.

Face lift has been developed by the desire to position drooping skin and make it look younger. Recently, a method of lifting drooping tissues using protrusions has been developed.

Registered Utility Model Publication No. 0320005 (registered on July 3, 2003) discloses `` Medical thread made of spinous processes on the surface of the thread. '' The disclosed yarns make the spines with hooked spines protruding on their surface in a certain direction or in a bidirectional or zigzag direction facing the spine, which causes the SMAS under the skin of the cheeks during facial wrinkle surgery. Move forward and fix the drooping of the skin at the same time. At this time, pull the skin tissue to the side to be fixed (ear side) using the thorn thread that emerges in both directions and insert the thorn thread into the subfacial fascia of the cheek area It will have the effect of pulling the sagging skin down without peeling the whole skin.

In addition, Japanese Patent Publication No. 0679160 (registered on January 30, 2007, International Publication No. WO 2003/103733, December 18, 2003, International Publication) discloses "Operating Room for Plastic Surgery." This patent provides various examples of a cosmetic operating room in which the oblique directions of the conical spine-like protrusions continuously alternate. This operating room is used for correcting facial wrinkles or soft tissue sewage caused by a decrease or loss of skin elasticity, and in particular, to provide a lifting action, i.e., to soften soft tissue and securely fix it in a new position. It is used for plastic surgery to remove wrinkles on the drooping parts of the face by picking up wrinkles by inserting and pulling a thread under the soft and drooping part of the face.

As mentioned above, face lift using a thread to lift the soft tissues of the face has the advantage that it can be performed by a simple, non-incision method, but due to the weight of the skin tissue caught on the thread, the force is continuously down. As the bulge gradually bends down, and if it persists, the skin tissue leaves the bulge. In such a case, the skin sags again, making it difficult to maintain long-term surgical effects.

Accordingly, the present invention has been made to solve the above problems of the prior art.

As shown in FIG. 1, the operating room 100 includes a plurality of protrusions in the form of a conical spine formed by protruding in a direction inclined with respect to the length direction of the seal body from the seal body 110 extending in the longitudinal direction and the seal body ( 120).

The operating room 100 may include a first region 101 having no protrusions starting at one end, a second region 102 having protrusions projecting in a first oblique direction, and a third region 103 having no protrusions formed again. ), A fourth region 104 in which protrusions protruding in the second inclined direction opposite to the first inclination direction and a fifth region 105 in which no protrusions are formed are sequentially arranged.

The protrusions 120 are formed on the surface of the seal body 110, and are formed on the first virtual line 130 and the second virtual line 140 of the seal body 110. Herein, the virtual line is not actually formed, but means a virtual line connecting the roots of the formed protrusions 120. The first virtual line 130 and the second virtual line 140 are positioned opposite to, or opposite to, the center line 150 of the seal body. The

imaginary lines

130 and 140 are preferably straight lines, as shown in FIG. 1, but may be spirals that rotate about the center line 150 of the seal body.

The inclination of the protrusions 120 formed on the first and second

virtual lines

130 and 140 is formed in the first inclination direction in the second region 102 and in the second inclination direction in the fourth region 104. . At this time, the first inclination direction and the second inclination direction are opposite to each other. In the present specification, the inclination direction of the protrusion may be expressed as an angle formed by the seal body 110 and the protrusion 120. For example, a case in which the angle of the protrusion is an acute angle α may be expressed in the first inclination direction and the The case where the angle of the projection is an obtuse angle β can be expressed in the second inclined direction. Therefore, as shown in FIG. 1, when the reference direction of the center line 150 is the direction from the first area 101 to the fifth area 105, the first inclination direction is the length of the seal body 110. It forms an acute angle with respect to a direction, and a 2nd inclination direction makes an obtuse angle with respect to the longitudinal direction of a seal body.

The protrusions 120 formed along the first and second

virtual lines

130 and 140 are preferably arranged to be symmetrical with respect to the longitudinal center line 150 of the seal body, but may be arranged in a zigzag form.

The cross-sectional shape of the seal body 110 is not particularly limited, but in order to arrange the first and second

imaginary lines

130 and 140 opposite to each other, it is preferable that the seal body 110 be a polygon in a circle, an ellipse, or a quadrangle or more.

The length of the third region 103 is approximately 2 cm, the length of the second and

fourth regions

102 and 104 is 5 to 10 cm, and the length of the first and

fifth regions

101 and 105 is 2 to May be 10 cm.

Figure 2 is a view showing the needle included in the surgical tool for skin tissue lifting according to an embodiment of the present invention. The needle included in the surgical tool of the present invention has a hollow barrel shape to accommodate the operating room therein, and is divided into a straight shape (200 or 200 ') and an arc shape (300 or 300'). .

The

needles

200, 200 ', 300, and 300' have tip ends 220, 220 ', 320, 320' at one end of the

barrel

210, 210 ', 310, 310', which are It consists of pointed ends that can penetrate the skin. The tip end portion may be formed such that the opening of the empty space of the stem is exposed in the longitudinal direction of the needle, but in this case, since the skin tissue is injured by sticking the needle to the skin, the length of the needle is preferably It is preferable that the openings of the hollow spaces of the barrel are not exposed in the direction, and the

openings

230, 230 ′, 330, and 330 ′ of the hollow spaces of the barrel are formed in a direction perpendicular to the length of the barrel. In Fig. 2, the opening shape of the tip end portion is illustrated. That is, the openings are not exposed at all at the distal end (200 and 300) and the distal ends are removed at about half, so that the opening is basically open upward but partially exposed at the distal end (200 'and 300). ') Is illustrated. The former has a rather blunt distal end that results in less damage to the skin tissue, while the latter has a slightly sharper distal end that results in more severe damage to the skin tissue than the former. However, even the latter is less damaging to the skin tissue than a needle in the form of an opening exposed in the longitudinal direction of the stem.

The

needles

200, 200 ′, 300, and 300 ′ also have thread inserts 240, 240 ′, 340, 340 ′ at the opposite ends of the tip ends 220, 220 ′, 320, 320 ′. In this case, the

openings

250, 250 ′, 350, and 350 ′ of the empty spaces of the long sides into which the operating room 100 is inserted are exposed in the longitudinal direction of the long sides. The cross-sectional area of the

openings

250, 250 ', 350, 350' is equal to the cross-sectional area of the empty space of the long when the long is cut vertically.

On the other hand, in order to more easily insert the operating room 100 into the

thread insertion portion

240, 240 ', 340, 340' of the needle (200, 200 ', 300, and 300'), for example, The thread insert 240 of the 200 has a shape inclined inward at its distal end as shown in FIG. 10 so that the diameter of the opening 250 at the distal end is slightly smaller than the inner diameter of the needle body 210. It is desirable to make it large.

Figure 3 is a view showing the adapter included in the surgical tool for skin tissue lifting according to an embodiment of the present invention. The adapter 400 serves to induce the insertion of the operating room 100 into the needle 200, the opposite end of the tip end of the needle 200, that is, the opening 250 is exposed and It has a coupling portion 410 to engage with the cylindrical side. For convenience, only the distal end 240 of the opening 250 side of the needle 200 is shown. Coupling portion 410 has a hollow 415 that can accommodate the thread inserting portion 240 of the needle 200 therein. The hollow 415 is formed by the inner wall of the coupling portion 410, is exposed to the outside by the opening 416, and tapered by the connector 417 on the opposite side of the opening 416, ie inside the coupling portion 410. It is connected to the hollow 423 of the portion 420. The connector 417 is a hole having a diameter smaller than that of the hollow 415 and the opening 416, so that the coupling portion 410 has a latching jaw 413 formed to protrude inwardly from the inner wall. The needle 200 accommodated in the hollow 415 of the coupling part 410 is caught by the locking jaw 413 so that it can no longer move and engages with the coupling part. Accordingly, the diameter of the connector 417 coincides with the diameter of the hollow space of the needle 200, that is, the diameter of the opening 250.

The taper portion 420 is formed in succession to the coupling portion 410, and has a hollow 423 therein. The hollow 423 of the tapered portion 420 is formed by the inner wall 421 and is formed in the shape of a truncated cone that gradually increases in diameter starting from a hole coinciding with the diameter of the opening 250 of the needle 200. This is a passage for easily inserting the operating room 100 into the needle 200. The hollow 423 of the tapered portion 420 is exposed to the outside by the opening 425.

Thus, after inserting the needle 200 into the coupling portion 410 of the adapter 400, the operation room 100 having a projection is inserted into the wide opening 423 of the tapered portion 420, and the operating room 100 is a needle ( It is guided into the 200 and easily inserted into the needle (100). Using such an adapter 400 it is possible to easily insert the operating room 100 is a projection formed in the needle 200.

As such, after inserting the operating room 100 into the needle 200 using the adapter 400, the adapter 400 can be removed by removing the needle 400 to the opposite side of the needle 200, but the surgical tool of the present invention When performing a face lift using the same, there is a case that the adapter 400 can not be removed as such, even in this case, in order to remove the adapter, one side of the coupling part 410 and the taper part 420 A slit 430 is formed over. The slit 430 allows the operating room 100 to fall sideways through it.

Figure 4 is a view showing a skin expander and skin peeler included in the surgical tool for skin tissue lift according to an embodiment of the present invention. The skin expander 500 is used to form a hole larger than the needle hole in the skin layer by puncturing the skin layer with a needle to form a fine needle hole, and then inserting into the needle hole to expand the skin layer. The skin expander 500 includes a tip 510 having a conical shape having a sharp point and gradually increasing diameter, a handle 520, and a connection 530 connecting the tip and the handle.

Skin exfoliators

600 and 700 are used to insert into the enlarged holes formed by skin expander 500 and to separate the skin layer from the SMAS (Superficial Muscular Aponeurotic System) layer around the holes. Two types of skin peelers may be used. The first skin peeler 600 includes an elliptical plate-shaped end portion 610, a handle portion 620, and a connection portion 630 connecting the end portion and the handle portion. The second skin peeler 700 includes a distal end 710 in the form of a "-" wire, a handle 720, and a connection 730 connecting the distal end and the handle. The first skin exfoliator 600 is inserted into a hole expanded by the skin expander 500 and used to separate the skin layer from the SMAS layer in the vicinity of the hole, and the second skin exfoliator 700 expands. It is used to separate a wider range of skin layers separated near the perforated skin pores.

Now, with reference to the drawings of Figure 5 to Figure 9 will be described the process and the result of performing a face lift using the surgical tool according to the present invention.

5 is a view showing a shape in which the operating room is inserted into the facial skin as a result of performing the face lift using the surgical tool for skin tissue lifting of the present invention. In FIG. 5, the inserted operating room 100 corresponds to the first region 101, the D′-A region to the second region 102, the AB region to the third region 103, and so on. The BC ′ region corresponds to the fourth region 104 and the C′-C region corresponds to the fifth region 105, respectively. The C-D region may correspond to the first region 101 or the fifth region 105. Since the operating room inserted into the facial skin in this shape has protrusions formed in the direction of preventing the sagging of the cheeks down in the D'-A and BC 'regions, the cheeks are tightened up after the sagging cheeks are pulled up. It is pulled and thus serves to maintain a wrinkle free state. Thus, when using the surgical instrument of the present invention, by simply inserting the operating room into the face and pulling it upwards, that is to say the hair is in place to tighten the skin and fix the open ends of the operating room tied to each other by the weight of the cheek meat By preventing the escape from the projection of the operating room, the effect of the operation can be maintained for a long time.

Figure 6 is a view showing a process of inserting the operating room to the lower face as the first step of performing a face lift using the surgical tool for skin tissue lift of the present invention, Figure 7 is a surgical tool for skin tissue lift of the present invention As a step to perform a face lift using a step showing a process of inserting the operating room from the lower face to the upper face, Figure 8 is a step to perform a face lift using the surgical tool for skin tissue lift of the present invention Is an explanatory diagram of a phenomenon in which bending occurs on the skin surface of the face when the face is lifted by pulling the operating room inserted into the face and measures to prevent it, and FIG. 9 illustrates the bending of the face on the skin surface of the face described in FIG. 8. A diagram showing a specific process of measures to prevent the phenomenon that occurs.

Referring to the process of performing a face lift using the surgical tool for skin tissue lift of the present invention. First, as shown in FIG. 6, the circular needle needle 300 is used to float the lower part of the face like a thread to penetrate the needle 300. At this time, the part of the face floating with the needle is the area A-B shown in Fig. 5, the point A is a portion into which the needle enters and the point B is a portion from which the needle comes out.

The face includes a skin layer 20 and a fascia layer 30 called Superficial Muscular Aponeurotic System (SMAS) under it, and tissues such as nerves, blood vessels, and structures are distributed under the SMAS layer 30. . Therefore, the needle 300 is inserted at the point A and sequentially penetrates the skin layer 20 and the SMAS layer 30, and then penetrates the SMAS layer 30 and the skin layer 20 in turn and is exposed to the outside at the B point. .

After inserting the arc-shaped needle 300, the adapter 400 is inserted into the needle 300, the operating room 100 is penetrated through the needle 300, and both ends of the operating room 100 to the outside. Expose In this state, the adapter 400 is removed from the operating room 100 and the needle 300 is removed. The operating room 100 is then inserted into the face between the A and B points of the facial skin. That is, the third region 103 of the operating room 100 passes through the skin layer 20 and the SMAS layer 30 between the A and B points of the facial skin and hangs on the SMAS layer 30. The remaining

regions

101, 102, 104, and 105 of 100 are exposed to the outside.

Next, as shown in Figure 7, the operating room 100 is a part D of the face covered by the hair after piercing the skin layer through a long straight needle long needle 200 to the points A and B of the skin exposed; And in C, the needle is exposed to the outside. Then, after inserting the straight needle 200, the adapter 400 is inserted into the needle 200 and the operating room 100 penetrates the needle 300, and then both ends of the operating room 100 Expose to the outside. In this state, the adapter 400 is removed from the operating room 100 through the slit 430 and the needle 200 is also pulled out. Then, as shown in FIG. 7, the operating room 100 penetrates the skin layer 20 horizontally between the B and C points of the facial skin and is exposed to the outside at the C point. Similarly, although not shown in the drawing, the operating room 100 penetrates the skin layer 20 horizontally between the A and D points of the facial skin and is exposed to the outside at the D point. Meanwhile, since the skin layer has elasticity, when the two strands of the operating room 20 exposed to the point C and the D are pulled, the point A and the point B of the operating room located on the surface of the skin are lowered to the top of the SMAS layer 30. It is located at. In FIG. 7, the linear needle 200 is drawn in a slightly compressed state, which represents that the needle can be flexible enough to bend when the needle 200 is inserted into the facial skin.

Next, referring to FIG. 5, two strands of the operating room 100 exposed at C and D points are pulled to lift and tighten sagging facial skin. Then, the sagging face skin is lifted up and the raised skin is caught by projections formed in the second area (D'-A area) and the fourth area (C'-B area) of the operating room 100 and sagging down again. It will keep the tension. Then, by tying the two strands of the exposed operating room 100 with each other and removing the stalks, the operating room 100 is formed in a completely closed shape. In this case, when the C point and the D point are close to each other, the two ends of the operating room 100 exposed immediately may be bundled with each other.

If point C and point D are far apart and it is difficult to tie the two ends of the exposed operating room 100 directly together, the operating room 100 exposed at point C is floated to or near point D in the manner described above. Place them close together, tie the two exposed strands together and remove the stalks. That is, after penetrating the skin layer from the point C to the point D with an arc-shaped needle 300, the operating room 100 exposed at the point C using the adapter 400 is inserted into the needle 300 and the adapter When the 400 and the needle 300 is removed, the exposed two ends of the operating room 100 are located close to each other. Then you can easily tie them together.

When the operating room exposed to the skin surface is slightly pushed down by hand, the elasticity of the skin lowers the skin layer and makes it invisible to the naked eye. In addition, since the position to tie the operating room 100 is a position covered by the hair bundle position and state of the operating room 100 is not very noticeable. In other words, it does not undermine the cosmetic value of facelift.

Meanwhile, as shown in FIG. 8, when two strands of the operating room 100 exposed at the C and D points are pulled to lift and tighten the sagging facial skin, the sagging facial skin becomes taut as a whole. The skin layers near the two points A and B which hang on layer 30 are bent. The reason for this is as follows. Pulling the exposed operating room 100 of the two strands SMAS layer 30 is lifted up. In Figure 8 the upper part of the face is in the right direction. At this time, the SMAS layer 30 below the A and B points (left direction in FIG. 8) is expanded by the pulling force and the SMAS layer 30 above the A and B points (right direction in FIG. 8) Because of the force pulled up, it moves upwards, but relatively less, causing bending near that point. The skin layer 20 is bent on the curved SMAS layer because it is coupled with the SMAS layer 30. That is, the bending of the SMAS layer 30 is transferred to the skin layer 20. In FIG. 8, the point of the SMAS 30 layer on which the operating room 100 is caught is denoted by B, the point of the skin layer 20 on it is denoted by B ′, and the operating room is caught before the operating room 100 is pulled. The points of the SMAS layer 30 were marked by B ".

On the other hand, the reason for bending in the skin layer near two points A and B may be explained as follows. That is, when the protrusions of the second and

fourth regions

102 and 104 of the operating room lift the skin tissue, the outer skin may be further lowered due to the difference between the portion where the skin and the thread are located. Although the part where the thread is located is moved up, the part where the thread is located and the skin differ by the thickness. Therefore, in the skin immediately above the position caught in the third region 103 of the operating room, the skin gathers and a crying phenomenon occurs.

Such bending of the skin layer 30 is not preferable because it is a factor that reduces the effect of skin molding. In order to prevent this phenomenon, the skin layer 20 and the SMAS layer 30 may be separated from the A and B points and the vicinity thereof. Then the SMAS layer 30 is bent as mentioned above, but the skin layer 20 is not bent because it is separated from the curved SMAS layer part. That is, the curvature of the SMAS layer 30 is not transferred to the skin layer 20. In addition, as the skin layer is rearranged by such peeling, the crying phenomenon of the skin surface is reduced.

As such, the process as shown in FIG. 9 is performed to prevent the bending of the SMAS layer 30 to be transferred to the skin layer 20. First, the skin layer 20 of points A and B is drilled with the needle 800 to form a needle through hole 24. Thereafter, the tip 510 of the skin expander 500 is inserted into the needle through hole 24 to form an expansion hole 26 having an enlarged size of the through hole. Since the skin is highly elastic, the skin expander 500 can be used after the small holes to expand the size of the holes from the small holes. If the expanded expansion hole 26 is left as it is, the hole is closed again due to the elasticity of the skin, but the size of the hole is maintained for a short time.

After the expansion hole 26 is formed by the skin expander 500, the

skin exfoliators

600 and 700 are inserted into the expansion hole 26, and the skin layer 20 is removed from the SMAS layer 30 near the hole. Peel off. Skin exfoliation may be performed using any of the

skin exfoliators

600 and 700, but preferably, the skin exfoliator 600 is first used to exfoliate the skin near the extension hole 26 and then skin exfoliation. The skin 700 is used to peel off the skin at a position farther from the expansion hole 26.

When performing face lift using a conventional yarn with a cog, the skin tissue is moved by the force of the protrusion and the skin tissue is maintained at such a position. However, when the weight of the skin tissue is out of the force of the protrusion, The skin tissue sometimes escaped from the bumps, making it difficult to achieve the purpose of the surgery. On the contrary, if facial elevation is performed using the surgical tool for skin tissue elevation according to the present invention, the yarns with protrusions form a closed loop completely in the skin tissue, thereby fundamentally preventing sagging of the skin tissue. In addition, in the prior art, the load concentrated on only the protrusion of the thread is dispersed by not only the protrusion part of the thread but also the closed part of the thread by the surgical thread of the present invention, so that the raised skin tissue, in particular, the facial skin tissue can be stably maintained. . Furthermore, using the operating room and other surgical instruments of the present invention, it is possible to prevent the skin tissue crying (phenomena of skin tissue clumping) by pulling the skin tissue drooping downward. As a result, the use of the surgical tool of the present invention can be used not only convenient to perform the face lift by a non-incisional simple method, but also to achieve a cosmetic improvement and the effect lasts for a long time.
