Description

Technical Field

[0001] This invention relates to nasal implants and rhinoplasty methods using nasal implants. More specifically, this invention relates to nasal implants and rhinoplasty methods using nasal implants, wherein the main body of the nasal implant is formed in a conical shape, allowing easy insertion through a pinhole; protrusions are formed on the outer peripheral surface of the main body, ensuring stable fixation of stacked nasal implants without slippage; and a groove is formed at the end of the position adjustment portion of the nasal implant, allowing for easy and clean cutting of the position adjustment portion after the nasal implant has been inserted into the bridge of the nose. Background Technology

[0002] With the development of modern medicine, plastic surgery is increasingly providing patients with confidence and satisfaction by beautifully sculpting parts of the body.

[0003] In particular, because the nose is located in the center of the face and affects first impressions, rhinoplasty is widely performed to make the nose more beautiful.

[0004] In most cases, rhinoplasty is performed to increase the height of the bridge of the nose. Surgeries also exist to correct a crooked nose or reduce the size of the nostrils.

[0005] In this type of rhinoplasty, a silicone nasal implant may be inserted into the bridge of the nose.

[0006] like Figure 1 As shown in (a), in order to perform a rhinoplasty using a silicone nasal implant 20, an incision 12 is made on one or both sides of the portion above the nostril 11. Alternatively, as... Figure 1 As shown in (b), an incision 12 is formed across the two nostrils 11 and the nasal columella.

[0007] Subsequently, as Figure 2 As shown, a silicone nasal implant 20, manufactured to fit the shape of the patient's nose, is inserted through incision 12.

[0008] After the surgery is completed by inserting a silicone nasal implant 20, the incision 12 is sutured with sutures.

[0009] The operation method of using the above-described silicone nasal implant 20 has the following advantages: it is inexpensive, easy to process the nasal implant into the desired shape, and the nasal implant 20 has high support strength, which makes it possible to reliably elevate the bridge of the nose.

[0010] However, because the surface of the silicone nasal implant 20 is smooth, the nasal implant 20 has low adhesion to human tissue, which makes it difficult to fix the nasal implant 20.

[0011] Furthermore, because the silicone nasal implant 20 is a monolithic structure manufactured to fit the shape of the nose, it is difficult to insert the nasal implant 20 into the accurate position in one go.

[0012] Therefore, if the silicone nasal implant is bent during insertion, a second surgery is required.

[0013] In addition, the problem with the silicone nasal implant 20 is that the incision 12 must be sutured after it is inserted into the nose, and foreign body reaction and inflammatory reaction may occur after insertion.

[0014] At the same time, such as Figure 3 As shown, a method has been proposed to replace the silicone implant 20 with an insertion wire 30 inserted into the living body.

[0015] The method of using the insertion suture 30 involves using a suture in a skin-lifting procedure. The insertion suture 30 consists of a main body 31 with a certain diameter and a plurality of spiky protrusions 32 formed on the main body 31.

[0016] The spinous processes 32 are configured to tilt in opposite directions to pull the skin when inserted.

[0017] According to the insertion line 30 described above, it has the advantages of being able to be inserted without forming an incision and being able to improve the support strength to human tissue through multiple spiky protrusions 32.

[0018] Furthermore, by continuously inserting the insertion lines 30, a desired shape or pattern can be achieved.

[0019] However, as described above, the insertion line 30 causes the spiky protrusions 32 to form in the opposite direction in order to achieve a skin lifting effect, which has the disadvantage of not being suitable for rhinoplasty methods.

[0020] That is, due to the spiky protrusions 32 formed in the opposite direction, there is a problem that it is not easy to push the insertion line 30 into the nose.

[0021] Furthermore, due to the spiky protrusions 32, it is difficult to stack multiple lines. In the case of multiple stacks, the spiky protrusions 32 may be exposed on the outside of the nose.

[0022] As a result, even the experts encountered difficulties during the surgery, and patient satisfaction was low.

[0023] In some cases, autologous cartilage and fat, which are part of the body, are inserted into the nose.

[0024] This method has the advantage of superior adhesion and fixation relative to human tissue, but it has the disadvantage of requiring separate operations to harvest a part of the body. Summary of the Invention

[0025] Technical issues

[0026] In view of the inherent problems in the related art, one object of the present invention is to enable the easy insertion and stacking of multiple nasal prostheses even through a pinhole.

[0027] Another object of the present invention is to eliminate the need to form an incision for inserting a nasal prosthesis into the bridge of the nose, and to eliminate the need to suture the incision after surgery.

[0028] Another object of the present invention is to enable the fixed position of a nasal prosthesis inserted into the nose, or to stack additional nasal prostheses while adjusting their position.

[0029] Another objective of the present invention is to increase the friction between multiple stacked nasal implants so that the multiple nasal implants can be stably fixed without moving.

[0030] Another object of the present invention is to make it easy to cut the position adjustment portion exposed outside the nose after the nasal prosthesis has been inserted into the nose.

[0031] Another object of the present invention is to make it easy to remove the nasal prosthesis inserted into the nose and to easily perform additional operations.

[0032] Problem-solving methods

[0033] According to one aspect of the present invention, a nasal prosthesis for insertion into the bridge of a human nose is provided, the nasal prosthesis comprising: an insertion tip having a pointed end; a tapered body portion having a diameter that gradually increases rearward; a rear end portion disposed at the rear of the tapered body portion; and a position adjustment portion extending from the rear end portion of the tapered body portion to adjust the position of the nasal prosthesis, wherein the rear end portion is formed in a hemispherical or tapered shape, and a circumferential groove is formed at the connection between the rear end portion and the position adjustment portion.

[0034] Mesh protrusions, circular protrusions, longitudinally extending protrusions, spiral protrusions, or longitudinally spaced protrusions may be formed on the circumferential surface of the conical main body.

[0035] The nasal prosthesis and the position adjustment part can be made of non-absorbent materials including silicone and nylon.

[0036] The nasal prosthesis and the position adjustment part may be made of an absorbent material selected from the group consisting of polydioxanone, poly-L-lactic acid, polycaprolactone, and calcium hydroxylapatite.

[0037] According to another aspect of the present invention, a rhinoplasty method for inserting a nasal prosthesis into the bridge of the nose of a human body is provided, the rhinoplasty method comprising the following steps: (a) forming an insertion hole on the anterior surface of the bridge of the nose by an injection needle (S10); (b) inserting the nasal prosthesis having a position adjustment portion into the insertion hole (S20); (c) while holding the position adjustment portion of the inserted nasal prosthesis by hand, inserting and stacking an additional prosthesis (S30); (d) cutting the externally exposed end of the position adjustment portion (S40); and (e) attaching a regeneration bandage to cover the insertion hole (S50).

[0038] In step S20, the main body of the nasal prosthesis and the position adjustment part are positioned in the insertion device and then inserted into the nose.

[0039] In step S20, only the position adjustment part of the nasal prosthesis is positioned within the insertion device and then inserted into the nose.

[0040] Invention Effects

[0041] According to the present invention, the following effects can be obtained.

[0042] First, because the shape of a nasal implant resembles a gently sloping cone with a sharp tip, multiple nasal implants can be inserted through a pinhole.

[0043] As a result, unlike silicone nasal implants, it does not require large incisions or postoperative suturing.

[0044] Secondly, since the nasal implant itself has a position adjustment part, an additional implant can be inserted while holding the position adjustment part of the already inserted implant in your hand.

[0045] Therefore, it can prevent the position of the inserted nasal prosthesis from being changed due to the addition of an inserted nasal prosthesis, and adjust the position of the inserted nasal prosthesis when necessary.

[0046] Third, because the rear end of the nasal implant is shaped into a hemispherical or conical shape, an additional nasal implant can be easily inserted through the space at the rear end of the adjacent nasal implant.

[0047] Fourth, since a protrusion of a certain height is formed on the main body of the nasal implant, the inserted nasal implant can be stably fixed by increasing the friction between the stacked nasal implants.

[0048] Fifth, after the nasal implant is inserted, the height or direction of the nasal implant can be easily corrected using the position adjustment unit, and the inserted nasal implant can be easily removed.

[0049] Sixth, since a groove is formed circumferentially at the connection between the rear end and the position adjustment part, the position adjustment part exposed outside the nose can be easily cut after the conical main body is inserted into the bridge of the nose.

[0050] Therefore, it can prevent the cutting plane from protruding or moving when cutting the end of the position adjustment part, and the end of the position adjustment part can be easily and cleanly cut at the same cutting position.

[0051] Seventh, the procedure can be completed simply by attaching a skin regeneration band to the needle mark after the nasal implant is inserted.

[0052] Eighth, recovery time can be shortened by minimizing possible bruising or swelling after surgery, and skin contractures can be prevented. Attached Figure Description

[0062] In the following text, reference will be made to Figures 4 to 9 The nasal prosthesis according to the present invention and the rhinoplasty method using the nasal prosthesis are described in detail.

[0063] First, the nasal prosthesis (hereinafter simply referred to as "prosthesis") according to the present invention will be described.

[0064] like Figure 5 As shown, the prosthesis 50 of the present invention includes an insertion tip 51 with a pointed tip, a tapered main body portion 52 with a diameter that gradually increases rearward, and a rear end portion 53 disposed at the rear of the tapered main body portion 52.

[0065] The reason for forming the tapered main body 52 into a gently tapered shape is to take into account the structure of the nose, which rises as it descends.

[0066] If the implant is stacked while keeping the diameter of the conical body 52 constant, the upper part of the nose becomes too high and its aesthetic appearance is poor.

[0067] By using the structure of the aforementioned prosthesis 50, such as Figure 4 As shown, a fine insertion hole 13 can be formed on the front surface of the bridge of the nose 10 using an injection needle, and multiple implants 50 can be inserted sequentially through the insertion hole 13.

[0068] Therefore, it is not necessary to form a long incision as in the case of inserting a silicone implant, nor is it necessary to suture the incision after surgery.

[0069] In addition, the rear end portion 53 of the prosthesis 50 is preferably formed in a hemispherical or conical shape.

[0070] Through the above structure, such as Figure 7 As shown, a space is created between adjacent prostheses 50, and a prosthesis 50 with a tip can be easily inserted through this space.

[0071] According to the present invention, a position adjustment part 54 is further provided at the rear end 53 of the conical prosthesis 50.

[0072] Since the position adjustment unit 54 is not an insertion line used during the lifting operation (see...) Figure 3 Instead, it is a part used to adjust the position of the prosthesis, so no spiky protrusions are formed on the position adjustment part 54.

[0073] Furthermore, in this invention, a groove 54a is formed circumferentially at the connection between the rear end portion 53 and the position adjustment portion 54.

[0074] The groove 54a is preferably formed as follows: Figure 5 The V-shaped cross-section shown is shown.

[0075] Through the groove 54a, after the nasal implant 50 is inserted into the nose, the end of the position adjustment part 54 exposed to the outside of the nose can be easily cut.

[0076] In the prosthesis 50 according to the invention, preferably, such as Figure 5As shown, protrusions of various shapes are formed on the circumferential surface of the conical main body 52.

[0077] like Figure 5 (a) to Figure 5 As shown in (e), the protrusions can be formed as mesh protrusions 55, circular protrusions 56, longitudinally extending protrusions 57, spiral protrusions 58, and longitudinally spaced protrusions 59. However, the shape of the protrusions is not limited to these.

[0078] When the prostheses are stacked in 50 layers, the protrusions increase friction, which can stably fix the adjacent stacked prostheses in place.

[0079] Furthermore, if the protrusion is too high, it may be difficult to insert the implant. Therefore, the protrusion is formed to have an appropriate size and height, taking into account the size of the implant.

[0080] In addition, the prosthesis 50 and the position adjustment part 54 of the present invention may be made of non-absorbent materials such as silicone or nylon.

[0081] Alternatively, the prosthesis 50 can be made of an absorbent material that melts over time and is absorbed into the body.

[0082] Examples of absorbent materials preferably include polydioxanone (PDO), poly-L-lactic acid (PLLA), polycaprolactone (PCL), and calcium hydroxyapatite (CaHA).

[0083] Next, we will refer to Figures 6 to 9 A rhinoplasty method using a nasal prosthesis according to the present invention is described.

[0084] The rhinoplasty method according to the present invention is a rhinoplasty method for inserting a nasal prosthesis 50 into the bridge of the nose of a human body, the rhinoplasty method comprising the following steps: (a) forming an insertion hole 13 on the anterior surface of the bridge of the nose 10 by an injection needle (S10); (b) inserting a nasal prosthesis 50 having a position adjustment portion 54 into the insertion hole 13 (S20); (c) while holding the position adjustment portion 54 of the inserted prosthesis 50 by hand, inserting and stacking an additional prosthesis 50 (S30); (d) cutting the position adjustment portion 54 exposed outside the nose (S40); and (e) attaching a regeneration bandage to cover the insertion hole 13 (S50).

[0085] In step S10, as Figure 4 As shown, a fine insertion hole 13 is formed on the front surface of the bridge of the nose 10 by an injection needle. In step S20, the prosthesis 50, which is provided with a position adjustment part 54, is inserted into the insertion hole 13.

[0086] In this invention, since the insertion tip 51 of the prosthesis 50 has a pointed tip, multiple prostheses can be inserted through the insertion hole 13 formed by the injection needle.

[0087] Therefore, unlike silicone implants, it does not require a long incision or postoperative suturing.

[0088] In step S20, the conical prosthesis 50 can be inserted directly by hand, or by means of... Figure 9 The insertion device shown in (a) is inserted.

[0089] At this time, as Figure 9 As shown in (a), both the tapered main body 52 and the position adjustment part 54 of the prosthesis 50 can be positioned within the insertion device 60 (commonly referred to as a cannula) and then inserted into the nose, or as... Figure 9 As shown in (b), only the position adjustment part 54 of the prosthesis 50 can be positioned within the insertion device 60 and then inserted into the nose.

[0090] exist Figure 9 In case (a), the insertion device 60 is inserted into the nose, the prosthesis 50 is pushed inward by the pusher (not shown), and then the insertion device 60 is pulled out while pressing the main body of the prosthesis.

[0091] exist Figure 9 In case (b), only the position adjustment part 54 is positioned inside the insertion device 60, and the prosthesis 50 is pushed inward by the pusher.

[0092] In step S30, as Figure 7 As shown, while holding the position adjustment part 54 of the inserted prosthesis 50 with one hand, the additional prosthesis 50 is pushed inward through the insertion hole 13.

[0093] At this time, since the position adjustment unit 54 is held by hand, the first inserted prosthesis 50 and the additional inserted prosthesis 50 will not be pushed inward together, or the position of the first inserted prosthesis 50 will change.

[0094] Furthermore, since the rear end 53 of the prosthesis 50 is formed in a hemispherical or conical shape, a certain space is formed at the rear end of each of the adjacent stacked prostheses 50.

[0095] Therefore, the prosthesis 50 can be continuously inserted by pushing the sharp insertion tip 51 into the space.

[0096] Figure 6 An example of a rhinoplasty method according to the present invention is shown. Figure 6 (a) shows the implant inserted into the entire bridge of the nose. Figure 6 (b) shows the prosthesis being inserted into the tip of the nose. Figure 6 (c) shows the insertion of the prosthesis into the nasal columella.

[0097] After inserting all the appropriate number of implants 50, the position adjustment section exposed outside the nose is removed.

[0098] At this time, the end of the position adjustment part 54 can be easily and cleanly cut through the groove 54a formed at the connection between the rear end 53 and the position adjustment part 54.

[0099] Subsequently, a skin regeneration bandage (not shown) is attached to cover the insertion hole 13, thereby completing the procedure.

[0100] Using silicone prostheses 20 (see...) Figure 1 Conventional rhinoplasty methods are inexpensive and can reliably raise the bridge of the nose. However, the incision must be large and must be re-sutured after surgery. It is difficult to insert the implant into the correct position in one go. The implant has poor adhesion to human tissue.

[0101] In addition, absorption line 30 (see Figure 2 Conventional rhinoplasty methods do not require incisions. However, due to the spiky protrusions 32 formed in the opposite direction, it is difficult to push the thread 30 into the nose and to stack multiple implants.

[0102] This invention utilizes the advantages of both silicone implant insertion methods and absorbable suture insertion methods. The rhinoplasty method according to the invention is a method in which the main body of the implant is formed into a small-diameter cone shape, and multiple implants are stacked.

[0103] Accordingly, Figure 4 As shown, multiple prostheses can be inserted through the insertion hole 13 without forming an incision.

[0104] In addition, because multiple protrusions are formed on the outer peripheral surface of the main body of the prosthesis, the stacked prostheses can be stably fixed without slipping.

[0105] In addition, such as Figure 7 As shown, because the rear end of the prosthesis is formed into a hemispherical or conical shape, additional prostheses with sharp ends can be continuously inserted through the space between adjacent prostheses.

[0106] Furthermore, since the additional prosthesis is inserted while the position adjustment part of the already inserted prosthesis is held by hand, the position of the already inserted prosthesis can be prevented from changing, and the position of the already inserted prosthesis can be adjusted as needed.

[0107] Furthermore, since a groove is formed circumferentially at the connection between the rear end and the position adjustment part, the end of the position adjustment part can be easily and cleanly cut after the conical main body is inserted.

[0108] The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. Various modifications and changes can be made without departing from the scope and spirit of the present invention as defined in the claims.
