Biomechanical loading device for in-vivo research on osseointegration

The utility model discloses a biomechanical loading device for in-vivo research on osseointegration, which comprises a base, a lower limb fixing mechanism and a mechanical loading mechanism, and four fixing columns are arranged on the base; the lower limb fixing mechanism comprises a tibia placing frame and a door-shaped baffle which are arranged left and right, and the tibia placing frame is arranged on the base through two telescopic columns; the door-shaped baffle plate is fixed on the base; a semicircular groove is vertically formed in the left side face of the n-shaped baffle. The central axis of the semicircular groove is perpendicular to the central axis of the tibia placing frame. The mechanical loading mechanism comprises a motor and a push plate. According to the biomechanical loading device for in-vivo research on osseointegration, an in-vivo osseointegration process is artificially created by constructing a tibia near-end titanium nail prosthesis implantation model, and then in-vivo controllable m
