Description

[Technical field]

[0001] The present invention relates to a nose model that can be used in plastic surgery, and more particularly to an assembled nose model for explaining the process of nose surgery, which is used to inform a patient of changes in the appearance of the nose due to surgery during an interview with the patient before the surgery. [Background technology]

[0002] As medical technology advances and the desire to have a beautiful face grows, more and more people are undergoing facial plastic surgery. In particular, the nose, which is located in the center of the face, has a great impact on one's impression, so the number of cases of nose plastic surgery is also increasing.

[0003] There are various nose reshaping methods, and depending on the type of incision, they can be classified into closed type, in which only the inside of the nose is incised, and open type, in which the outside of the nose is also incised. Open type surgery is a method in which the skin incision line starts from the mucous membrane inside the nose and connects to the outside of the nose columella, exposing the incision site to the outside. It has the advantage of making nose reshaping easier as the field of vision is secured, but it is troublesome to have to fix the bridge of the nose while covering the incision site after surgery.

[0004] 1 shows a simplified view of the internal structure of a nose 101. As shown in the figure, upper lateral cartilage 105, lower lateral cartilage 107, and nasal septum cartilage 109 are located below the nasal bone 103. The upper lateral cartilage 105, lower lateral cartilage 107, and nasal septum cartilage 109 are covered by skin to maintain the shape of the nose.

[0005] In particular, by fixing the nasal septum cartilage (harvested separately) between the lower lateral cartilages and raising the lower lateral cartilage, the left and right sides of the nose can be balanced and a high nose shape can be achieved; these are points that plastic surgeons explain to patients during consultations regarding nose surgery. Summary of the Invention [Problem to be solved by the invention]

[0006] However, since the above explanations are given only in words or using pictures or models, it is often difficult for patients (without medical knowledge) to understand what the lower lateral cartilage is and how it moves, which reduces the effectiveness of the explanation. Conventional nose models only show the cross-sectional shape of the nose part and have the limitation that they cannot realize the movement of the lower lateral cartilage. There is a need for a nose model with a structure that can actually move the lower lateral cartilage and thus improve the patient's understanding.

[0007] The present invention has been made to solve these problems, and its purpose is to provide an assembled nose model for explaining the procedure of rhinoplasty surgery, which can be disassembled and assembled, so that damaged parts can be easily replaced during use, and the part corresponding to the lower lateral cartilage can be moved, so that the patient can be more easily informed of the changes in the appearance of the nose due to the surgery. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the assembled nose model for explaining the process of nasal plastic surgery of the present invention is used to show changes in the appearance of the nose due to nasal plastic surgery, and includes a main body having a nasal bone corresponding part formed on the front side and a through-space below the nasal bone corresponding part, a fixed body that is detachably connected to the through-space, an upper lateral cartilage corresponding part that is supported by the fixed body and protrudes forward from the main body and is located below the nasal bone corresponding part, and a lower lateral cartilage corresponding part that is adjustable in position below the upper lateral cartilage corresponding part. The fixed body further includes a fixed post that is removably attached to the rear surface of the main body and provides support, and a center plate that is integrated with the fixed post and accommodated inside the through-space and supports the upper lateral cartilage corresponding portion and the lower lateral cartilage corresponding portion. In addition, the center plate is a vertical plate-like member that is positioned in the center of the through space and divides the through space into left and right parts, and the lower part of the center plate includes a holder that supports the lower lateral cartilage corresponding part in an adjustable position. In addition, the holder extends in the front-to-back direction and provides an accommodation space that is open to the front and bottom via an open slit, and a connecting part is installed at the lower lateral cartilage corresponding part, which is accommodated and held in the accommodation space of the holder and receives supporting force from the holder. The connecting portion further includes a locking ball accommodated in the accommodating space so as to be positionally adjustable, and an extension rod that connects the locking ball to the lower lateral cartilage corresponding portion. The holder is further provided with an access passage for passing the locking ball into the holder or for passing the locking ball in the holder to the outside of the holder. In addition, a holder cap is further provided on the lower side of the holder, which is detachably coupled to the lower portion of the holder and blocks the inlet / outlet passage. The holder cap is detachably coupled to the fixed post and has a holder receiving portion that partially covers the open slit of the holder. In addition, a number of fixing grooves are provided on the upper side of the center plate, and insertion protrusions that fit into the fixing grooves are provided on the upper lateral cartilage corresponding portion. The fixed post is a rod-shaped member that crosses the through hole vertically, and the rear surface of the body is provided with fitting grooves that detachably receive the upper and lower ends of the fixed post. Effect of the Invention

[0009] The assembled nose model for explaining the nose surgery procedure of the present invention configured as described above can be disassembled and reassembled, so if some parts are damaged during use, the damaged parts can be easily replaced. In addition, the part corresponding to the lower lateral cartilage can be moved, so that the patient can be more easily informed of the changes in the appearance of the nose due to the surgery.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

[0012] Basically, the nose model of the present invention is a structure made in the shape of a human nose and can be used, for example, in plastic surgery hospitals, for example, during interviews with patients prior to nose surgery to inform them of the changes in the appearance of their nose due to the surgery.

[0013] Such a nose model is used to show changes in the appearance of the nose due to nasal plastic surgery, and basically comprises a main body having a nasal bone corresponding part formed on the front side and a through-space below the nasal bone corresponding part, a fixed body that is detachably connected to the through-space, an upper lateral cartilage corresponding part that is supported by the fixed body and protrudes forward from the main body and is located below the nasal bone corresponding part, and a lower lateral cartilage corresponding part that is adjustable in position below the upper lateral cartilage corresponding part.

[0014] Fig. 2 is a perspective view of an assembled nose model 10 for explaining a nasal plastic surgery procedure according to an embodiment of the present invention, Fig. 3 is a view showing the rear of the nose model shown in Fig. 2, Fig. 4 is a side view of the nose model of Fig. 2, Fig. 5 is a view for explaining the movement characteristics of the lower lateral cartilage corresponding part in the nose model, and Fig. 6 is a perspective view showing an overall exploded view of the nose model of Fig. 2. Fig. 7 is a view showing the upper lateral cartilage corresponding part and the lower lateral cartilage corresponding part mounted on a fixed body, and Fig. 8 is a cross-sectional view showing the mounting state of the upper lateral cartilage corresponding part and the lower lateral cartilage corresponding part on the fixed body.

[0015] As shown in the figure, the assembled nose model 10 according to this embodiment includes a main body 11, a fixed body 20, an upper lateral cartilage corresponding portion 31, a lower lateral cartilage corresponding portion 41, and a holder cap 27.

[0016] The main body 11 is a member simulating the portion of the facial bone where the nose is located, and has a nasal bone corresponding portion 11a on the front surface. The nasal bone corresponding portion 11a corresponds to the nasal bone and is inclined downward toward the front.

[0017] Further, a through space 11c is provided below the nasal bone corresponding portion 11a. The through space 11c is a passage through which the nasal cartilage is exposed to the outside in an actual facial bone. In this embodiment, a fixed body 20 is attached to the through space 11c.

[0018] 3, a fitting groove 11e is provided on the rear surface of the main body 11. The fitting groove 11e is a groove that detachably accommodates the upper and lower ends of a fixed post 21, which will be described later. When the upper and lower ends of the fixed post 21 are pressed into the fitting groove 11e, the fixed body 20 is joined to the main body 11. It is obvious that the user can also apply force to remove the fixed post 21 from the fitting groove 11e. The main body 11 can be manufactured by injection molding or 3D printing.

[0019] The fixed body 20 is a supporting member for supporting the upper lateral cartilage corresponding part 31 and the lower lateral cartilage corresponding part 41, and as described above, is detachable from the main body 11. The fixed body 20 can be separated from the main body 11 in order to replace or maintain the upper lateral cartilage corresponding part 31 or the lower lateral cartilage corresponding part 41.

[0020] The fixed body 20 includes a fixed post 21 and a center plate 23. The fixed post 21 is a rod-shaped member extending vertically, and the upper and lower ends are fitted and fixed in the fitting groove 11e to provide support. The fixed post 21 attached to the fitting groove 11e crosses the center of the through space 11c vertically to divide the through space 11c into left and right.

[0021] The center plate 23 is a plate-like member having a certain thickness, and is integrated with one side of the fixing post 21. The center plate 23 is disposed in the center of the through space 11c, dividing the through space into left and right. The reason for positioning the center plate 23 in the center of the through space 11c is to align the upper lateral cartilage corresponding part 31 and the lower lateral cartilage corresponding part 41 with the downward extension line of the nasal bone corresponding part 11a.

[0022] As described above, the center plate 23 supports the upper lateral cartilage corresponding portion 31 and the lower lateral cartilage corresponding portion 41 in a state in which the center plate 23 is housed inside the through-space 11c.

[0023] In order to fix the upper lateral cartilage corresponding part 31 to the center plate 23, a number of fixing grooves 23a are provided on the upper thickness surface of the center plate 23, and insertion protrusions are provided on the inner surface of the upper lateral cartilage corresponding part 31. The upper lateral cartilage corresponding part 31 is joined to the center plate 23 by fitting the insertion protrusions 31a into the fixing grooves 23a. It is of course possible to separate the upper lateral cartilage corresponding part 31 from the center plate 23.

[0024] As long as the upper lateral cartilage corresponding part 31 can be detachably fixed to the center plate 23, the method of fixing the upper lateral cartilage corresponding part 31 to the center plate 23 can be changed as many times as desired.

[0025] The upper lateral cartilage corresponding part 31 is a member replacing the upper lateral cartilage 105 constituting the nose (101 in Fig. 1), and as shown in Fig. 5, it protrudes forward from the main body 11 and is located below the nasal bone corresponding part 11a. The upper lateral cartilage corresponding part 31 can also be produced by a 3D printer. The upper lateral cartilage corresponding part 31 is somewhat soft and elastically deformable.

[0026] A holder 25 is formed integrally with the lower side of the center plate 23 to support a lower lateral cartilage corresponding portion 41 so that the position of the holder 25 is adjustable.

[0027] The holder 25 is integrated with the lower part of the center plate 23 and provides an accommodation space 25a as shown in Fig. 8. The accommodation space 25a is a space extending in the front-rear direction and partially accommodates the connecting part. The holder 25 has a shape like a hollow capsule.

[0028] The receiving space 25a is opened forward and downward through the opening slit 25e. The opening slit 25e has a width allowing the extension rod 43 to pass therethrough. Furthermore, an inlet / outlet passage 25c is further provided on the lower side of the holder 25. The inlet / outlet passage 25c is a hole through which the locking ball 45 described later can enter and exit. That is, it is a passage for inserting the locking ball 45 into the receiving space 25a or for removing the locking ball in the receiving space 25a to the outside of the holder 25. Since the holder 25 is thus provided with the inlet / outlet passage 25c and the opening slit 25e, not only the position of the lower lateral cartilage corresponding part 41 relative to the holder 25 can be adjusted, but also it can be replaced as many times as desired.

[0029] 4 and 5, the lower lateral cartilage corresponding part 41 is installed below the upper lateral cartilage corresponding part 31 in a position adjustable manner. The lower lateral cartilage corresponding part 41 is a part that replaces the lower lateral cartilage (107 in FIG. 1) located at the tip of the nose 101.

[0030] The upper lateral cartilage corresponding part 31 and the lower lateral cartilage corresponding part 41 are exposed in front of the through space 11c when assembled to the center plate 23. When the skin corresponding part 15 is placed over the upper lateral cartilage corresponding part 31 and the lower lateral cartilage corresponding part 41 in a state where they are exposed in front, the shape of a nose can be realized. The skin corresponding part 15 is molded and manufactured from elastic silicone, and covers the front surface of the nose model. The skin corresponding part 15 is adhered to the main body 11, the upper lateral cartilage corresponding part 31, and the lower lateral cartilage corresponding part 41, and can be removed as necessary.

[0031] In particular, the position of the lower lateral cartilage corresponding part 41 can be adjusted in the direction of the arrow a and the opposite direction, and in the direction of the arrow b and the opposite direction in Fig. 5. That is, it can be raised in the direction of the arrow a and lowered in the opposite direction, and can be pulled out in the direction of the arrow b and retracted in the opposite direction.

[0032] A connecting part is integrally provided on the lower lateral cartilage corresponding part 41 so that the lower lateral cartilage corresponding part 41 can move in the above-mentioned manner. The connecting part is a part that is partially received and held in the receiving space 25a of the holder 25 and receives a supporting force from the holder 25, and includes a locking ball 45 and an extension rod 43.

[0033] The locking ball 45 has a spherical shape and is accommodated in the receiving space 25a so that its position can be adjusted. The diameter of the locking ball 45 is the same as the inner diameter of the receiving space 25a. Therefore, the locking ball 45 cannot move freely in the receiving space 25a due to friction, and moves only when the user applies force. The locking ball 45 can pass through the entrance and exit passage 25c.

[0034] The extension rod 43 is a linear member that connects the locking ball 45 and the lower lateral cartilage corresponding part 41. The extension rod 43 passes through the open slit 25e and is movable along the open slit 25e. By applying the extension rod 43, the lower lateral cartilage corresponding part 41 can be moved in the direction of the arrow b in FIG. 5 or in the opposite direction.

[0035] Since the position of the lower lateral cartilage 107 is adjusted during actual nasal plastic surgery to correct the shape of the nose, the assembled nose model 10 is also configured so that the lower lateral cartilage corresponding part 41 can be moved. Therefore, for example, a doctor can move the lower lateral cartilage corresponding part 41 while holding the assembled nose model 10 in his / her hand, and more easily explain to the patient, "The patient's nose is currently in a certain shape, so if we move the lower lateral cartilage corresponding part 41 this way, the nose will become neater."

[0036] The holder cap 27 is a member that is detachably coupled to the lower side of the holder 25 and blocks a part of the access passage 25c and the open slit 25e. The holder cap 27 is separated from the holder 25 in order to replace the lower lateral cartilage corresponding part 41.

[0037] The holder cap 27 is provided with a coupling groove 27a. The coupling groove 27a is a portion that is coupled to the fixed post 21 at the lower part of the center plate 23. The fixed post 21 is fitted into the coupling groove 27a by an interference fit method to maintain the coupled state.

[0038] The holder cap 27 further includes a holder receiving portion 27c and a side wall portion 27e. The holder receiving portion 27c is a portion that covers part of the access passage 25c and the open slit 25e at the bottom of the holder 25. Since the holder receiving portion 27c covers the access passage 25c and the open slit 25e, there is no risk of the extension rod 43 and the locking ball 45 slipping out to the bottom.

[0039] Moreover, the side wall portion 27e is a portion that comes into close contact with the outer peripheral surface of the holder 25, and prevents the holder cap 27 from shaking, thereby preventing a decrease in the joining force of the fixed post 21 to the joining groove 27a.

[0040] As a result, the assembled nose model 10 of this embodiment configured as described above can be disassembled and assembled into individual parts, so that damaged or worn out parts can be individually replaced and maintained. In addition, since the lower lateral cartilage corresponding part 41 can move, information about nose surgery can be explained to the patient three-dimensionally, so that the patient can understand the explanation and make a decision about the surgery.

[0041] Although the present invention has been described in detail above with reference to specific embodiments, the present invention is not limited to the above embodiments, and various modifications can be made by those having ordinary skill in the art within the scope of the technical concept of the present invention.
