Product capable of control dissolving rate of medical orthopedic implant material and manufacturing method thereof

Abstract

The invention relates to a finished product which can be used for controlling the dissolution rate of orthopedic implant adopted in biomedicine and the production method thereof. The invention provides a technique which can be used for controlling the dissolution rate of orthopedic implant used in biomedicine. The technique is characterized in that by controlling the conditions of the constant temperature and the constant humidity, the treatment solution is diffused into the surface of the orthopedic implant used in biomedicine through the vacuum extraction technique, so that a second phase is generated on the surface of the implant, and is utilized as the means to control the dissolution rate. If the category of the treatment solution is changed, a second phase which is different with the implant substrate in crystallographic structure and components can be formed on the surface of the implant. The technique is also characterized in that the orthopedic implant used in biomedicine is in a laminar concentric circle structure. By utilizing the generated second phase and the laminar concentric circle structure, the invention can be taken as a means for controlling the medicine release carrier of the orthopedic implant used in biomedicine.

Description

technical field [0001] The present invention relates to a finished product and a manufacturing method capable of controlling the dissolution rate of biomedical orthopedic implant materials. It utilizes controlled constant temperature and constant humidity conditions to diffuse and react the treatment solution into the biomedical orthopedic implant materials with vacuum extraction technology, resulting in the A second phase is formed on the surface of the implanted material. Background technique [0002] In recent years, orthopedics often encounters cases of osteoporosis and osteoporosis in clinical practice. As the population grows older, the demand for bone substitute products is even greater. Partial defects caused by diseases. Local defects caused by trauma and bone diseases only need to be repaired. In addition to the traditional methods of autologous bone transplantation, homogeneous bones, and processed animal bones, filling materials, The commonly used filling mater...

AI Technical Summary

Problems solved by technology

However, there are often shortcomings such as difficulty in obtaining, rejection by the patient, infection, secondary surgery, too fast dissolution rate, and ingrowth of soft fibrous tissue.

At the same time, in order to adapt to the various complex shapes of human bone repair and the relative stress generated, the actual use of the above-mentioned bone filling materials is greatly restricted.
