Problems solved by technology

[0005] The object of the present invention is to provide a rat passive exercise-induced Achilles tendon strain modeling device to solve the problem of the small hindlimb bearing load caused by the light weight of the rat when using the active overload running model of the rat in the prior art. When you feel tired, you will take the initiative to stop running and fail to reach the preset target overload running standard, and you cannot induce Achilles tendon strain.

Abstract

The invention discloses a rat passive motion induced achilles tendon strain modeling device which comprises a support, a rat fixing device arranged at the top of the support and a driving assembly arranged in the support, and through holes are formed in the positions, at the rear side of the rat fixing device, of the top of the support; and the driving assembly comprises driven gears arranged at the left side and the right side of the support and a driving device for driving the driven gears to rotate, and rear limb fixing devices rotationally connected with the driven gears are eccentricallyarranged on the opposite faces of the two driven gears. During use, the abdomen of a rat is fixed to the rat fixing device, the hind limbs enter the support through the through holes, the hind limbs are fixed to a hind limb fixing device, the driving device is started, the driven gears rotate, and the hind limbs fixed to the driven gears form a passive running state, so that according to the preset overload standard, the movement time and the hind limb movement posture are adjusted, the achilles tendons of the rat are made to stretch out and draw back in an overload manner within a short time,and finally a achilles tendon strain model with the extremely high biomimetic property is obtained rapidly and efficiently.

Description

technical field [0001] The invention relates to the technical field of rat Achilles tendon strain modeling, in particular to a rat passive motion-induced Achilles tendon strain modeling device. Background technique [0002] Clinically, Achilles tendon injury caused by overloaded exercise accounts for the vast majority of sports injuries. Therefore, it is particularly important to study the pathogenesis of Achilles tendon strain caused by overloaded exercise. In order to study its pathogenesis, construct a biosimilar The animal model of Achilles tendon strain caused by overload exercise with high feasibility, reliability and repeatability is extremely critical. At present, the commonly used animal model of Achilles tendon strain is the active overload running model of rats. Active overload running on board induces Achilles tendon strain. [0003] However, this model takes a long time and is less feasible. First, because rats are light in weight, the load on their active runn...
