preparation example Construction

[0039] refer to image 3 As shown, the present invention also proposes a preparation method for filling the same costal cartilage material for rhinoplasty, comprising the following steps:

[0040] A) Bone extraction, the costal cartilage is obtained under a sterile environment, wherein the costal cartilage is a region.

[0041] B) processing, the obtained costal cartilage is sequentially degreased, decalcified, deproteinized and sterilized;

[0042] C) Carve, carve the costal cartilage after the above treatment into the desired shape.

[0043] Concrete process in the step B of the present invention comprises:

[0044] (1) immerse the costal cartilage in the mixed liquid of chloroform and methanol for 6-24 hours; wherein: the volume ratio of chloroform and methanol in the mixed liquid of chloroform and methanol is 1:1;

[0045] (2) adding the costal cartilage treated in the above step (1) into the hydrochloric acid solution, and continuously stirring for 8-12 hours; the conc...

Embodiment 1

[0050] 1. Obtain autologous rib cartilage in a sterile environment; preferably remove the eleventh or twelfth rib, clean it with distilled water and soak it;

[0051] 2. Immerse the costal cartilage in a mixed liquid of chloroform and methanol for 24 hours to degrease; wherein: the volume ratio of chloroform and methanol in the mixed liquid of chloroform and methanol is 1:1, and clean it with distilled water after taking it out;

[0052] 3. Immerse the degreased costal cartilage in a hydrochloric acid solution with a concentration of 0.5mol / L, and keep stirring for 12 hours to decalcify it, and wash it with distilled water after taking it out;

[0053] 4. Immerse the decalcified costal cartilage in a mixed solution of TritonX-100 and ammonia water for 72 hours to deproteinize; wherein, the volume percentage of TritonX-100 in the mixed solution of TritonX-100 and ammonia water is 1.5%, The mass percentage of ammonia is 0.3%, and after taking it out, it is cleaned with distilled...

Embodiment 2

[0057] 1. Obtain non-autologous rib cartilage in a sterile environment; preferably remove the eleventh or twelfth rib, clean it with distilled water and soak it;

[0058] 2. Immerse the costal cartilage in a mixed liquid of chloroform and methanol for 24 hours to degrease; wherein: the volume ratio of chloroform and methanol in the mixed liquid of chloroform and methanol is 1:1, and clean it with distilled water after taking it out;

[0059] 3. Immerse the degreased costal cartilage in a hydrochloric acid solution with a concentration of 0.6mol / L, and keep stirring for 12 hours for decalcification, and wash it with distilled water after taking it out;

[0060] 4. Immerse the decalcified costal cartilage in a mixed solution of TritonX-100 and ammonia water for 72 hours to deproteinize; wherein, the volume percentage of TritonX-100 in the mixed solution of TritonX-100 and ammonia water is 0.5%, The mass percentage of ammonia is 0.3%, and after taking it out, it is cleaned with d...

Abstract

The invention relates to a same-kind costicartilage material for nasal part plastic filling and a preparation method therefor. The same-kind costicartilage material structure comprises a nasal bone base body prepared from a self-body costicartilage or a non-self-body costicartilage, wherein the nasal bone base body comprises an apex nasi, a columella nasi and a nasal bridge; the nasal bridge is connected with the columella nasi through the apex nasi; the lower part of the nasal bridge consists of two nasal bridge sections which are arranged in a V-shaped crossing manner; a human nasal bone is positioned between the two nasal bridge sections; and a plurality of holes are densely formed in the surface of the nasal bridge. The material has the beneficial effects as follows: by virtue of the design of the nasal bridge sections, an implant can be tightly contacted with the nasal bone without causing displacement or abrasion; by virtue of the holes in the nasal bridge, a liquid can flow to the holes to enable human body tissues to be grown in the holes so as to connect the nose and the nasal implant into one body, so that the moving, falling off and festering of the nasal implant can be prevented, and pain feeling of a patient after surgery can be prevented. The method is applicable to autotransplant and allosome bone treatment.

Description

technical field [0001] The invention relates to the technical field of plastic surgery, in particular to a material for filling the same kind of costal cartilage in rhinoplasty and a preparation method thereof. Background technique [0002] Rhinoplasty (facelift) surgery is to change the height and shape of the nose by implanting appropriate materials so that it is in harmony with other parts of the face. It is the most common surgery in the field of plastic surgery. [0003] In medicine, there are many kinds of rhinoplasty materials, such as medical silicone rubber, autologous cartilage, animal tendon or ligament, expanded body (polytetrafluoroethylene), hyaluronic acid, etc. There are also many preparation methods for nasal bridge prosthesis. Among them, autologous cartilage is self-sourced, so there will be no rejection and no allergies, but it is difficult to shape during the production process. Animal tendons and ligaments are used as raw materials, because their compo...
