Abstract

The invention discloses a joint-moving simulation test system with a biological culture function, which comprises a joint simulator and a biological culture circulating system, wherein the biological culture circulating system comprises a culture cavity, a dislocated sterilized glass fermentation tank and a liquid storage tank which are sequentially communicated, the culture cavity is composed of an upper cavity and a lower cavity which are communicated together, the upper cavity is communicated with the dislocated sterilized glass fermentation tank, and the lower cavity is connected with an inlet of the liquid storage tank; the upper cavity is connected with a horizontal axis of the joint simulator, and the lower cavity is connected with a longitudinal axis of the joint simulator. According to the joint-moving simulation test system disclosed by the invention, the joint simulator can realize the moving control on the culture cavity, and the dislocated sterilized glass fermentation tank can realize the control on the oxygen, carbon dioxide, pH value and temperature of culture liquid in the circulating system. The joint-moving simulation test system disclosed by the invention not only can carry out in-vitro culture on tissue engineered cartilages, but also can efficiently carry out an in-vitro friction and wear performance evaluation test on active joint cartilages.

Description

technical field [0001] The invention relates to a motion simulation test system, in particular to a joint motion simulation test system with biological cultivation function. Background technique [0002] Tissue engineered cartilage has been developed so far. Although there are many experimental research results and a small amount of clinical application, both the function after culture and the long-term effect after implantation are unsatisfactory. How to improve the function of tissue engineered cartilage and how to evaluate the degree of its function before it can be implanted are the focus of attention now. An important factor in tissue engineered cartilage culture is mechanical stimulation. A large number of studies have shown that appropriate mechanical stimulation can increase the expression of cartilage matrix components such as collagen and polysaccharide protein, thereby improving the performance of tissue engineered cartilage. So far, the mechanical stimuli used ...
