Description

technical field [0001] The invention relates to a biomechanical loading device based on hard materials. Background technique [0002] Bone tissue is a mechanically loaded organ that supports the human body, so bone tissue is always in a complex biomechanical environment. Bone cells such as osteoblasts and chondrocytes have the ability to respond to biomechanical stimuli, and biomechanical signals in daily life can regulate the biological functions of various types of bone cells. Lack of effective mechanical stimulation can lead to imbalances in bone metabolism. For example, astronauts who have been in space for a long time in a weightless environment will experience significant bone loss in their weight-bearing bones. It can be seen that maintaining mechanical stimulation plays an important role in bone balance. In order to better explore the relationship between mechanical stimulation and bone tissue, it is necessary to clarify the biomechanical response mechanism of bone...

Problems solved by technology

However, most of the traditional biomechanical research uses the Flexcell system, which is completed by seeding cells on the flexible basement membrane and applying tensile or compressive stress to the basement membrane. This research mode cannot well simulate the bone tissue with high stiffness. Mechanical environment, thus limiting the generalization significance of its research results
