Description

Guide for nose surgery

The present invention relates to a guide for nasal cosmetic surgery that provides a guideline for straightly positioning a nose during a nasal cosmetic surgery.

Here, background art relating to the present disclosure is provided, and they are not necessarily meant to be known arts. Also, "transverse" or "species" is a convenient name for enhancing the understanding of components, and does not necessarily mean "lateral" or "species" as scientific angle terms.

Nose cosmetic surgery is performed when a nose deformed due to congenital nasal deformity, accidental fracture, sleeping disorder, or beauty. The types of nose surgery performed at this time are very diverse, and the type of surgery varies depending on the patient's condition, needs, type of deformation, type and method of previous surgery.

In recent years, cosmetic surgery has been rapidly increasing in consideration of the negative impact of the shape of the nose on human image and impression

The surgical methods are very diverse, but can be divided into two types depending on the type of incision: incision in the nasal cavity (non-open type) and incision in the nasal cavity (open type). A relatively simple operation can be performed using only the incision in the nasal cavity, but if it is too large or has a complex problem due to previous surgery, it may be necessary to make an incision outside the nose.

In the case of an open incision, the incision is started from the nasal mucosa to the outside of the nasal pillar, and the incision is exposed to the outside. Since the field of view is secured, nasal cosmetic surgery is advantageous. And it is necessary to position the nose straightly while covering the incision area. However, since it is made by the physician's senses and eyes, it is difficult to correct the correction, which is the biggest cause of the side effect of the nose .

FIG. 1 is a procedure diagram of measures for maintaining the symmetry of the nose during conventional nose surgery.

Conventional nose surgery usually takes the center line of the nose based on three points. The three points are the line connecting the midpoint between the interstices, the medial center, and the cupid bow of the lips as the center line of the nose, The symmetry of the left and right symmetrical center line is drawn by hand with the pen, the symmetry is confirmed during the operation at any time during the operation, the center line connecting the three center points is constructed again after the operation, .

However, in such a conventional method, various errors occur. There is an error in taking the initial center point (especially the inner center angle point) before the operation, an error in aligning the line with the laser, and an error in drawing the center line with the hand, The symmetrical confirmation of the implant is inaccurate and the center line construction for confirming the operation result is inaccurate after the operation, so that the error comparison before and after surgery is inaccurate and asymmetry occurs due to optical illusion in the surgical illumination environment in the hospital .

The fifth hole 320 is a hole for drawing the first reference point P1, the second reference point P2 and the third reference point P3, and the left and right lateral bodies 310 A scale 330 is provided on the left and right. Thus, with the transverse body positioned on the face, the right and left reference points, which are the same points on the left and right scales, can be accurately found and constructed.

For example, in order to construct the first reference point P1, it is possible to fix the lateral body 310 to the eye position and to find the center point from the inside of one eye to the inside of the other eye.

Meanwhile, it is preferable that the lateral guide 300 is used while being detachably attached to the longitudinal guide 100. In this case, it is possible to connect the guide for the nose shaping operation to the face in a crossed manner to the longitudinal guide 100, and to provide a sense of stability in the construction of the center line. In addition, it is possible to confirm whether the center line of the nose is positioned on the vertical line with respect to both eyes using a vertical guide which is positioned perpendicular to the lateral guides while the lateral guides are positioned in parallel with the both eyes.

The mounting of the longitudinal guide 100 of the lateral guide 300 can be done in various ways. 7 is an exploded perspective view showing an embodiment showing the combination of the lateral guide and the longitudinal guide.

A fifth hole 320 is formed at the center of the transverse guide body 310 and the first hole 120 of the longitudinal guide body 110 passes through the protrusion 121 of the bottom surface, So that the protrusion can be fitted into the fifth hole 320 to be detachably connected.

At this time, it is preferable to prevent the lateral guides and the longitudinal guides from being separated from each other after being detached. In this embodiment, the protrusions are provided with latching portions 123 at the ends thereof, It is possible to form the latching hole 330 in one area so that the latching part 123 can be passed only through the latching hole 330 so that the latching part 123 is inserted into the latching hole 330, desirable.

On both sides of the transverse direction guide, a sixth hole for constructing the second marking point T2 is provided.

The second marking point T2 is a point for indicating the fixed position of the lateral direction guide so that the nose shaping operation guide can be correctly positioned again like the first marking point T1. Thus, the sixth hole 350 is a hole that is opened on the end of the transverse body to construct the second marking point T2.

A face-contacting pad 360 may further be provided at an end of the lateral direction guide. The face contact pad can be stably attached to the face, and the coupling between the face contact pad 360 and the transverse guide end can be done in various ways, but a seventh hole 370 is formed in the face contact pad, And the sixth holes 350 are formed through the protrusions formed on the bottom surface so that the protrusions are inserted into the seventh holes 370 to be connected to each other.

8 to 10 are perspective views showing various embodiments of the present invention. According to this, the embodiment of FIG. 8 further includes a second lateral guide at the forehead region. The second transverse guide allows the naso-plastic surgery guide to be more easily attached to the face.

The embodiment of FIG. 9 shows a structure in which the combination of the longitudinal guide and the transverse guide is made in a manner to fit in the groove in an interference fit. It will be appreciated by those skilled in the art that the longitudinal and transverse guides can be attached to each other in a variety of ways.

In the embodiment of FIG. 10, the transverse direction guide has elasticity and extends to function as a ruler without a function that can be worn on the face. In addition, there is further provided a lateral guide, which is additionally placed on the eye, and a third lateral guide, which is located in the vicinity of the needle. The third transverse guide increases the adhesion to the face and makes the left and right reference points easier to construct. FIG. 11 is a schematic view of the wearer of the nose-shaping operation guide according to the embodiment of FIG.

Next, a description will be given of a method of manufacturing a guide for nose cosmetic surgery, which is another aspect of the present invention.

The guide for nasal cosmetic surgery according to an embodiment of the present invention can be tailored to the face of a patient. Since the height, face contour, and width of nose are different for every person, there is a possibility of failing to obtain an optimal center line when using standardized nose surgery guide.

Therefore, the manufacturing method of the guide for nasal cosmetic surgery of the present embodiment includes a photographing step, a shape converting step, a modeling step, and a manufacturing step.

The imaging step is a step of imaging and imaging the head or the face of the patient. In general, the patient can obtain CT images of the patient by using the head CT before the cosmetic surgery.

The shape conversion step is a step of converting the face into a three-dimensional shape based on the taken CT image. The 3D image of the face can be obtained through the photographing step and the shape converting step.

The modeling step is a step of performing modeling for 3D printing of a guide for nose shaping surgery suitable for a face converted into a three-dimensional shape. At the modeling stage, a guide model for customized nose surgery is established for individual patients based on images. That is, a model for a nasal cosmetic surgery is modeled that includes a body of a shape according to a person's facial characteristics and a hole that can be formed or observed on the body. FIG. 12 is a schematic view of a wearer wearing a facial three-dimensional modeling image and a guide for a nasal cosmetic surgery modeled accordingly.

The manufacturing step is to manufacture a guide for nose surgery with 3D printing. The nose cosmetic guide has a simple shape that can be manufactured by 3D printing, so it is possible to manufacture in a short time from photography to manufacture. FIG. 13 is a photograph of a guide for a nasal cosmetic surgery printed on an actual 3D printer.

In particular, when a guide for a nose-type cosmetic surgery is manufactured using 3D printing, it is possible to prepare for a medical dispute in comparison with a pre-operative image and a post-operative image, and selectively prepare an intraoperative image. As shown in FIG. 14, when the pre-operative, intra-operative, and post-operative images are acquired, the medical dispute is reduced.

That is, in order to confirm the shape difference of the face before and after the surgery, a body having a shape according to the facial characteristics, and a guide for a nasal cosmetic surgery including a hole that can be formed or observed on the body, After taking the images before the operation (Step 1), after taking the images after the surgery with the guide for the nose plastic surgery (Step 2) (Step 3) to confirm that the operation was performed successfully.

The features, structures, effects, and the like illustrated in the above-described embodiments can be combined and modified in other embodiments by those skilled in the art to which the embodiments belong. Therefore, it should be understood that the present invention is not limited to these combinations and modifications.
