Abstract

The invention discloses a multi-physical field integrated test system for natural joint tissue-oriented in vitro evaluation. The multi-physical field integrated test system comprises six work stations with the same structure, and each work station comprises an x-direction reciprocating motion unit and a z-direction loading unit; each x-direction motion unit also comprises an x-direction reciprocating motion unit, a loading unit, a biological culture dish and a friction force collecting unit; the six work stations share the y-direction reciprocating motion unit, and are fixed on a y-direction sliding table. The styles are tested from the x, y and z directions, so that tribological performance parameters of a natural joint tissue are acquired and evaluated in the approximate environment simulation state, and a foundation is laid for long-term and overall in vitro function evaluation on the active tissue.

Description

technical field [0001] The invention belongs to the technical field of in vitro evaluation of mechanical properties of biological joint osteochondral tissue, and relates to the in vitro bionics of comprehensive cultivation environments such as mechanics, physics and biochemistry inside the animal body where the biological tissue is located, and the in vitro dynamic monitoring and analysis of the performance of the biological tissue , specifically relates to a multi-physics comprehensive test system for natural joint tissue in vitro evaluation based on multi-physics and biological culture environment simulation. Background technique [0002] 1. Significance of in vitro test / in vitro biological culture of biological joint tissue [0003] Articular cartilage is very important for the various movements of the human knee, hip and other load-bearing joints in daily life. Diseases such as osteoarthritis and rheumatoid arthritis accompanied by lesions of cartilage tissue affect the...
