Embodiment

[0037] A gelatin embedding process for orthopedic implant materials, such as figure 1 shown. (the equipment used in the present invention is shown in Table 1, as figure 2 shown)

[0038] Technology of the present invention comprises the following steps:

[0039] (1) Preparation of bone particles:

[0040] Cut the fresh bovine bone into bone pellets with a diameter of 5mm*5mm, wash, degrease, decalcify and dry for later use; (the specific operation is the prior art, so it is omitted); put the bone pellets into the bone pellet preheating tank 1 for preheating to 50°C, stand-by;

[0041] A rubber-impregnated net basket is arranged in the bone grain preheating tank 1, and a rubber-impregnated net basket is also arranged in the vacuum gelatin preparation tank 2, and the rubber-impregnated net basket is not shown in the drawings.

[0042] (2) Preparation process of gelatin solution:

[0043] Weigh 750g of sterile gelatin with an electronic weighing scale according to the pres...

Abstract

The invention relates to a gelatin embedding process of an orthopedic implanting material and equipment thereof. The gelatin embedding process of orthopedic implanting material comprises the following steps: cutting beef bones into granular bone grains with the diameter of 5 millimeters, cleaning, degreasing, decalcifying and then airing; placing the prepared bone grains in a bone grain preheating tank to be preheated to 50 DEG C for standby; soaking gelatin in distilled water at room temperature for 30 minutes, transferring the gelatin to a vacuum gelatin preparation tank to be heated to 75-80 DEG C, uniformly stirring the gelatin, cooling the gelatin to 55 DEG C, adding antibiotics to the gelatin, uniformly stirring the mixture, standing for defoaming and preserving the temperature of 50-55 DEG C for standby; placing the preheated bone grains in the vacuum gelatin preparation tank, stirring, vacuumizing for 3 minutes, defoaming, transferring into an ice and water separating tank to separate the bone grains by using a stirrer, transferring into a vacuum drying cage to dry at the low temperature of 10 DEG C until 70% of water is removed, transferring into normal temperature for drying, collecting the bone grains and transferring to an airing rack. The invention can not reduce or denature the original somatotropin and can ensure the uniform content of the antibiotics and prevents the high-temperature destroy of the antibiotics; and the product has the advantages of uniform and trim appearance and batch production.

Description

technical field [0001] The invention relates to a gelatin embedding process and equipment for orthopedic implant materials, belonging to the technical field of medical auxiliary materials. Background technique [0002] At present, the method of bone particle implantation is used in orthopedic treatment, filling growth-stimulating hormone outside the bone particle, and then wrapping gelatin mixed with antibiotics, but there are defects of one kind or another, which are summarized as follows: [0003] a) The original somatotropin is reduced or denatured. [0004] b) Antibiotic content is uneven; easily damaged by high temperature; [0005] c) The appearance of the final product is uneven and uneven. [0006] d) The output of each batch is small. Contents of the invention [0007] In order to solve the above problems, the present invention overcomes the problems of reduction or denaturation of growth-promoting hormone in bone granules; uneven antibiotic content; easy to be...
