Problems solved by technology

[0003] The L-shaped nasal silicone prosthesis is the longest and most numerous material in clinical use, but there are still problems in the application process for many years: the nasal dorsum of the nasal prosthesis is usually straight and has poor fit with the patient's nasal bone, especially At the tip of the nasal prosthesis, after surgery, the prosthesis is not fit enough to make the prosthesis displace and deform the nose. In mild cases,

Embodiment 1

[0025] Embodiment 1: A nasal prosthesis, comprising the dorsum of the nose, the tip of the nose 3 and the columella 4 connected in sequence, the dorsum of the nose has an inner concave surface and an outer convex surface, and the arch angle of the outer convex surface of the nose dorsum is 70°. The dorsum of the nose includes the first dorsal area 1 and the second dorsum 2 of the nose. The width of the second dorsum of the nose 2 is smaller than the width of the first dorsum of the nose. 3; It can make the line of the back of the nose more beautiful and natural after rhinoplasty. The thickness of the two sides of the dorsal nose area 1 gradually becomes thinner from the middle of the dorsal nose area 1 to the side of the dorsal nose area 1, which can make the connection between the nasal prosthesis and the human nasal tissue more natural, and will not Sharp contour lines appear for improved aesthetics. There are four through holes 5 distributed in the middle part of the first...

Embodiment 2

[0026] Embodiment 2: A nasal prosthesis, comprising the dorsum of the nose, the tip of the nose 3 and the columella 4 connected in sequence, the dorsum of the nose has an inner concave surface and an outer convex surface, and the arch angle of the outer convex surface of the nose dorsum is 100°. The dorsum of the nose includes the first dorsal area 1 and the second dorsum 2 of the nose. The width of the second dorsum of the nose 2 is smaller than the width of the first dorsum of the nose. 3; It can make the line of the back of the nose more beautiful and natural after rhinoplasty.

Embodiment 3

[0027]Embodiment 3: A nasal prosthesis, comprising the dorsum of the nose, the tip of the nose 3 and the columella 4 connected in sequence, the dorsum of the nose has an inner concave surface and an outer convex surface, and the arch angle of the outer convex surface of the nose dorsum is 150°. The dorsum of the nose includes the first dorsal area 1 and the second dorsum 2 of the nose. The width of the second dorsum of the nose 2 is smaller than the width of the first dorsum of the nose. 3; It can make the line of the back of the nose more beautiful and natural after rhinoplasty.

Abstract

The invention discloses a nasal prosthesis. The nasal prosthesis comprises a nose back, a nose tip and a nasal columella, and the nose back is provided with an inner concave surface and an outer convex surface; multiple tooth-shaped grooves are formed in the two side edges of the nose back respectively, and multiple through holes are distributed in the middle of the nose back in the length direction of the nose back and run through the inner concave surface and the outer convex surface of the nose back; circular holes which run through the left and right side faces of the nose tip are formed in the nose tip, a crescent nose protection wing is fixed to the portion, close to the tip portion of the nose tip, on the outer surface of smooth transition connection of the nose tip and the outer convex surface of the nose back, the nose protection wing and the nose tip form a T shape, and the nose protection wing is provided with an arc outer surface of smooth transition; the nasal columella isprovided with an inclined surface which is aslant connected with the inner concave surface of the nose back, and an included angle between the inclined surface and the inner concave surface of the nose back is an obtuse angle. According to the nasal prosthesis, natural transition between the nasal prosthesis and the nasal tissue of the human body can be achieved, an obvious contour line cannot exist, the nasal prosthesis and the nasal tissue of the human body are gradually connected into an entirety along with time, the nasal prosthesis is stable in structure after healing, and displacement cannot occur.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a nasal prosthesis. Background technique [0002] At present, prosthesis rhinoplasty is a common operation in plastic surgery. Silicone nasal prosthesis is a commonly used material. The principle is to put the carved nasal prosthesis into the stripped cavity through a small incision in the nasal vestibule, and then Over time, the nasal tissue gradually heals together, thereby improving the facial image of the human body. [0003] The L-shaped nasal silicone prosthesis is the longest and most numerous material in clinical use, but there are still problems in the application process for many years: the nasal dorsum of the nasal prosthesis is usually straight and has poor fit with the patient's nasal bone, especially At the tip of the nasal prosthesis, after surgery, the prosthesis is not fit enough to make the prosthesis displace and deform the nose. In mild cases, the ...
