Problems solved by technology

[0004] 1. The biocomposite membrane has a relatively large volume area and a small fracture area, and 2 cannot be effectively fitted and fixed together
[0005] 2. The limitations of the current biocomposite membrane materials and manufacturing process lead to performance indicators such as the degradation rate of the biocomposite membrane and the time for the carried growth factors to release the effective drug concentration (the duration of the effective concentration is the key to the healing quality of the fracture line) Unable to meet clinical needs

Embodiment Construction

[0030] refer to figure 1 1. Batch production of molds for pointed biofilms, comprising the following steps:

[0031] 1) A model 2 with a rhombus-shaped section, a "V"-shaped long-side vertex, and a coincident vertex angle with the fracture line section is made in advance;

[0032] 2) Immerse the model in the first solution layer and the second solution layer in turn. The first solution forms an elastic layer, which is a dense degradable or non-degradable biofilm. The second solution layer forms a drug layer, and the material of the drug layer is human bone Biocompatible degradable or non-degradable, absorbent or non-absorbable or porous porous substances, and drugs that can promote bone healing are also encapsulated inside the drug layer;

[0033] 3) After the biological microstructure membrane 1 is air-dried and the shape is fixed, cut the prepared biological microstructure membrane 1 along the circumference of the ellipse of the model section according to the required size,...

Abstract

The invention provides a batch production mold of a pointed biological membrane. The mold comprises a long-strip-shaped wax model which has a diamond section, V-shaped vertex angles on the long edgesas well as matched vertex angles and bone fracture line section.

Description

technical field [0001] The invention relates to a mold for batch production of pointed biofilms. Background technique [0002] At present, it is a frontier field of medical research to use a biocomposite film containing growth factors / stem cells to stick to the fracture line to enhance the speed and quality of fracture healing. There are blood vessels and bone cells distributed on the inner surface of the fracture line (anastomosis line), and whether the healing is good depends on the growth of blood vessels and bone cells in the fracture line. The reason why biofilm sticking to the surface of fracture anastomosis can increase the quality of fracture healing is that on the one hand, the drugs encapsulated in the biofilm can promote the growth of blood vessels and bone cells in the fracture anastomosis, and on the other hand, the biological The membrane isolates external muscles and other human tissues from the fracture anastomotic line, and prevents the reaction of human ...
