CN204501107U - A kind of Novel nose prosthese - Google Patents

Abstract

The utility model discloses a novel nasal prosthesis, which comprises an L-shaped smooth body composed of the dorsum of the nose, the tip of the nose and the columella. The middle part of the dorsum of the nose is provided with a plurality of first blind holes, and the edge part is provided with a plurality of through-holes. hole. The nasal prosthesis of the present utility model adopts a hole arrangement method combining blind holes and through holes in the back of the nose, the thicker middle part of the back of the nose is provided with blind holes, and the thinner edge part is provided with through holes, so that The nasal tissue can quickly fill the blind hole and the through hole, and the nasal prosthesis is not easy to move and deform after being implanted in the human body, and because the depth of the blind hole and the through hole are shallow, the nasal tissue will not be overfilled , It also facilitates the surgical removal of the nasal prosthesis.

Description

A new type of nasal prosthesis

technical field

The utility model relates to the technical field of prostheses, in particular to a novel nasal prosthesis.

Background technique

When the nose changes from low to high, it is necessary to embed a certain thickness of filler in the nasal tissue. This filler is called a nasal prosthesis. The nasal prosthesis must be harmless to the human body, have no rejection, and do not deteriorate for a long time. It is made of materials that are soft, easy to shape and easy to take out. At present, most of the materials for nasal prosthesis are medical silicone rubber. After the operation, the prosthesis has the risk of moving and moving when it is subjected to external force collisions. In the prior art, in order to avoid the displacement of the nasal prosthesis, small holes are set on the nasal prosthesis, but the unreasonable design of the opening is very easy to cause The nasal prosthesis is fixed too firmly, and when the nasal prosthesis is taken out from the body, it will cause great pain to the patient.

Utility model content

The technical problem to be solved by the utility model is to provide a nasal prosthesis that does not displace and deform and is easy to take out by surgery.

The technical solution adopted by the utility model to solve the problems of the technologies described above is:

The utility model provides a novel nasal prosthesis, which comprises an L-shaped smooth body composed of the dorsum of the nose, the tip of the nose and the columella. The middle part of the dorsum of the nose is provided with a plurality of first blind holes, and the edge part is provided with a plurality of through-holes. hole.

As a further improvement of the above technical solution, a row of through holes is provided at the edge of the dorsum of the nose.

As a further improvement of the above technical solution, two rows of through holes are provided at the edge of the dorsum of the nose.

As a further improvement of the above technical solution, the end surface of the columella is provided with several second blind holes.

As a further improvement of the above technical solution, the material of the nasal prosthesis is medical silicone rubber for human body.

The beneficial effects of the utility model are:

The nasal prosthesis of the present utility model adopts a hole arrangement method combining blind holes and through holes in the back of the nose, the thicker middle part of the back of the nose is provided with blind holes, and the thinner edge part is provided with through holes, so that The nasal tissue can quickly fill the blind hole and the through hole, and the nasal prosthesis is not easy to move and deform after being implanted in the human body, and because the depth of the blind hole and the through hole are shallow, the nasal tissue will not be overfilled , It is also conducive to the surgical removal of nasal prosthesis.

Detailed ways

The idea, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, characteristics and effects of the present utility model. Apparently, the described embodiments are only some of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without paying creative efforts, All belong to the protection scope of the utility model. In addition, all the connection/connection relationships involved in the patent do not simply refer to the direct connection of components, but mean that a better connection structure can be formed by adding or reducing connection accessories according to specific implementation conditions. Each technical feature in the utility model can be combined interactively under the premise of not conflicting with each other.

As shown in Figures 1 to 3, the preferred embodiment of the utility model, the nasal prosthesis is an L-shaped smooth whole, including the dorsum of the nose 10, the tip of the nose 20 and the columella 30, and its material is preferably medical silicone rubber for human body .

The middle part of the back of the nose 10 is thicker and is provided with a number of first blind holes 11, and the edge of the back of the nose 10 is thinner and is provided with a number of through holes 12. The upper surface is densely arranged, and one or two rows of through holes 12 are arranged at the edge of the nasal dorsum 10. It should be noted that the number of rows of through holes 12 can be determined according to the thickness of the specific nasal prosthesis, preferably One or two rows, but not limited to. In this embodiment, preferably, the diameter of the first blind hole 11 and the through hole 12 is 0.2 mm, the distance between holes is 0.9 mm, and the depth of the first blind hole 11 is 0.02 mm.

The end face of columella 30 is a plane, and this end face is provided with some second blind holes 31, and the second blind holes 31 are also preferably small holes with a diameter of 0.2 mm, a hole spacing of 0.9 mm, and a depth of 0.02 mm, which is beneficial to the columella. The limit of 30 is fixed.

The above is a specific description of the preferred implementation of the utility model, but the utility model is not limited to the embodiments, and those skilled in the art can also make various equivalent deformations without violating the spirit of the utility model Or replacement, these equivalent modifications or replacements are all included within the scope defined by the claims of the present application.
