Description

Nasal implants {NASAL IMPLANT FOR PLASTIC SURGERY}

The present invention relates to a prosthesis for nose molding. More specifically, it relates to a nose molding prosthesis formed of a biodegradable material.

Rhinoplasty (Rhinoplastiy) can be performed for the purpose of correction to ameliorate diseases such as chronic nasal congestion, rhinitis, or more recently, it is also performed for cosmetic purposes.

Nose surgery for corrective purposes corrects the passage from the nostrils to the nasal passages to facilitate access of air and runny nose.

In cosmetic nose surgery, procedures such as bubbling nose, wild nose, and the like are transformed into a straight nose, or a nose is raised.

The most common method of rhinoplasty is to insert a implant, which may include silicone, gore-tex, or siltex, and fat or cartilage may be implanted. When fat or cartilage is transplanted, the fat or cartilage of the subject himself is extracted and used to prevent the immune response.

When implants are implanted under the nose skin and over time, problems such as inflammation and swelling can occur due to various causes, including adsorption with tissues.

In order to prevent this, biodegradable materials are used as implants, and the biodegradable materials are inserted into the body and gradually absorbed by the human body over time.

For example, Korean Patent Publication No. 10-1682954 discloses a biodegradable molding solid filler that can be fixed after being inserted into the subcutaneous layer, including a radial fixation, but when the biodegradable material is decomposed and absorbed into the human body, As it is returned to the state and form before surgery, there is a need for a study on methods that can sustain the effect of surgery even after the decomposition of biodegradable materials.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Although the following describes preferred embodiments of the present invention, these embodiments are only illustrative of the present invention and are not intended to limit the scope of the appended claims, and various modifications to the embodiments within the scope and spirit of the present invention. Modifications and variations are apparent to those skilled in the art, and such variations and modifications are naturally within the scope of the appended claims.

1 to 2 are front and perspective views showing the prosthesis for nose molding according to embodiments of the present invention.

1 and 2, the nose molding prosthesis 100 according to the embodiments of the present invention includes a body 110 and a through hole 210.

The body part 110 may include a biodegradable material and may include a through hole 210 formed in at least one region of the body part 110 and penetrating the body part 110. Body portion 110 may be configured as a biodegradable material, it may be formed of a biodegradable sheet formed or formed as a biodegradable material. In addition, the body portion 110 defines the external shape of the prosthesis 100 for nose molding.

When the biodegradable material is inserted into the human body, the biodegradable material may be a material that can be gradually decomposed and absorbed into the human body over time. In addition, the decomposed substance may be a substance which does not adversely affect the human body even when absorbed into the human body.

In some embodiments, the body portion 110 may include a shape having a curvature corresponding to the shape of the nasal cartilage. Therefore, after being inserted into the skin, it can be closely adhered to the cartilage of the nose and can be fixed more strongly.

For example, the shape of the body portion 110 may be a flat plate or a streamlined shape bent along the cartilage of the nose. When the shape of the body portion 110 is the flat plate, the body portion 110 may be processed according to a desired shape and size during nose surgery. If the shape of the body portion is manufactured in the shape of the cartilage of the nose can be used for nose surgery without processing the body portion 110.

In one embodiment, the body portion 110 may include a shape having a curvature corresponding to the shape of the nasal cartilage. When the body portion 110 has the shape, the adhesion of the inserted nose molding implant 100 may be improved, and thus, the nose molding implant 100 may be fixed to the inserted position, and the through hole ( The tissue can be easily filled in 210.

For example, the material forming the body portion 110 may include a material that does not cause an inflammatory response when inserted into the human body (eg, above the nose cartilage, below the nose skin).

In one embodiment, the biodegradable material is composed of caprolactone, lactic acid, glycolic acid, para-dioxanone and trimethylene carbonate It may be a polymer or copolymer formed from one or more monomers selected from the group consisting of or a mixture of the polymers or copolymers.

The polymer or copolymer or mixture of polymers or copolymers may be, for example, a substance that does not have a rejection response to the immune system even when inserted into the human body. Therefore, it may be a material that does not cause an inflammatory response even when inserted into the human body.

In addition, when the polymer or copolymer or the mixture of the polymer or copolymer is inserted into the human body, the monomer may be a substance absorbed into the human body while being gradually degraded as time passes. In addition, the monomer may be absorbed in the human body does not adversely affect the human body.

The through hole 210 may be arranged at a predetermined interval in the first half of the body portion (110).

For example, over time after the nose molding implant 100 is inserted under the nose skin, the skin tissue may fill the inside of the through hole 210, in which case the tissue filled inside the through hole 210 You can achieve a scaffold. Even if time passes by the skeleton and the nose molding implant 100 is substantially completely absorbed into the human body, the shape of the nose may maintain the shape before the implant is absorbed.

In addition, the prosthesis 100 for nose molding may be fixed to a portion inserted during surgery by a tissue filling the through hole 210. If the aperture 210 is not present, the implant may be inserted under the nose skin and then escape through the cut-out portion for insertion in surgery, for example, by external pressure or by the growth of skin tissue. have.

Therefore, when the tissue is formed in the through hole 210, the implant may be fixed at the position inserted in the nose surgery to solve the problem that the implant escapes to the outside by external pressure.

For example, the through hole 210 may be more densely arranged at the distal end of the body part 110, and the density of the through hole 210 may be about 20% to 30% higher at the distal end of the body part 110. When the density of the through hole 210 is higher than the nose end direction of the body part 110, since the amount of biological tissue is large in the nose end, the through hole 210 can be easily filled with the living tissue, and the nose molding prosthesis 100 It can improve the fixing force. In addition, as the number of the through holes 210 increases in the nose end direction end portion of the nose molding prosthesis 100, the distal end portion decreases in strength and flexibility, thereby preventing the nose molding prosthesis 100 from penetrating the surgical site. can do.

In one embodiment, the diameter of the through hole 210 may be 2mm to 5mm. When the diameter of the through hole 210 is within the above range, the diameter of the armature increases, the armature can be formed firmly. In addition, the through hole 210 is not excessively large to maintain the mechanical and physical strength of the nose molding prosthesis 100, and immediately after the nose surgery, the irregularities that may occur in the appearance of the nose before the tissue fills the through hole 210 It can prevent. More preferably, the diameter of the through hole 210 may be 2mm to 4mm.

In one embodiment, the through holes 210 may be arranged at intervals of 3 mm to 10 mm with adjacent holes.

The gap means a distance from the center of the through hole 210 to the center of the adjacent through hole.

For example, when the gap falls within the range, a gap between the through hole 210 and the adjacent through hole is secured enough to increase the mechanical strength of the body part 110. In addition, when the distance between the through holes 210 exceeds 10mm, as many through holes 210 are not formed as necessary, the number of the skeletons and the resulting appearance of the nose may be reduced. More preferably, the interval may be 4mm to 10mm.

In one embodiment, the spacing may have a value greater than or equal to the diameter of the through hole 210. In this case, when the through-hole 210 is not too dense and the nose molding prosthesis 100 is inserted into the nose, the appearance of the nose may be smooth without irregularities. In addition, the bacteria are not easy to breed, even if the infection by the bacteria can be easily treated to completely eradicate the bacteria, it is possible to suppress the occurrence of inflammation, and to facilitate the treatment when the inflammation occurs.

3 and 4 are front views of the nose molding prosthesis in accordance with some embodiments.

3 and 4, the through hole 210 and the adjacent through holes may be arranged with a certain rule.

Referring to FIG. 3, in one embodiment, the gap between the through hole 210 and the adjacent holes is constant, and the through hole 210 and the four adjacent holes may be arranged at an angle of 90 degrees.

The 90 degrees is an angle that can be viewed substantially 90 degrees, for example, it may mean 87 to 93 degrees.

Thus, the apertures 210 may be arranged in a substantially square grid, in which case the apertures 210 are arranged regularly and the skeleton is formed in a square grid to maintain the appearance of the nose after surgery. The effect and the fixing effect of the implant can be improved.

Referring to FIG. 4, in one embodiment, the gap between the through hole 210 and the adjacent holes is constant, and the through hole 210 and the three adjacent holes may be arranged at an angle of 120 degrees.

120 degrees is an angle that can be substantially viewed as 120 degrees, and for example, may mean 116 degrees to 124 degrees.

Thus, the apertures 210 may be arranged to form a substantially cubic lattice (eg, honeycomb), in which case the apertures 210 are regularly arranged and the skeleton within the nose forms a cube As formed regularly, it is possible to improve the effect of maintaining the appearance of the nose and fixing the implant after surgery.

In one embodiment, the through hole 210 may have a higher density at the outer portion than at the central portion with respect to the width direction of the body portion 110.

For example, when the body 110 is inserted into the nose skin, the central portion may be a portion where the nose is located, and the outer portion may include a side portion of the nose and a nose portion. In the part where the outer part of the nose is located, since there is more biological tissue than the dorsal part of the nose, when the density of the through hole 210 is formed higher in the outer part, the tissue is easily filled in the through hole 210, thereby forming a nose The fixing force of the prosthesis 100 can be improved, and even when the nose molding prosthesis 100 is decomposed, the shape of the prosthesis 100 can be maintained.
