Description

Technical Field

[0001] The utility model belongs to the technical field of medical research, and particularly relates to a limb marking cage based on gait analysis. Background Art

[0002] Skeletal muscle is one of the most abundant tissues in the human body and has the ability to regenerate itself following tissue damage. The regenerative capacity of skeletal muscle tissue is limited by the extent of the injury: severe damage can result in a permanent loss of muscle mass, thereby reducing, or in the worst case, completely impairing, muscle function. This disabling pathological condition, known as volumetric muscle loss (VML), is also a pathological condition that prevents myofiber regeneration and can occur after severe primary trauma (e.g., impact, blast, or penetrating injuries) or surgical ablation of sarcomas.

[0003] Since large experimental animal models such as pigs, goats, and sheep are similar to humans in anatomy and skeletal muscle proteomics, and their limb length, spinal cord morphology, and body weight are larger than those of rodents, they can better simulate the biomechanical forces of walking experienced by adult humans. Skeletal muscle tissue engineering medical research based on gait analysis of these animal models has great reference value for the treatment of skeletal muscle diseases in the human body.

[0004] When conducting a gait analysis experiment, it is usually necessary to immerse the animal's surgical limb in an ink box for marking, so as to facilitate the acquisition of the animal's surgical limb's gait when the animal walks. Because animals are prone to stress reactions such as struggling, running and jumping under mandatory human control, when existing gait analysis devices mark the animal's surgical limb, the animal will spill the ink box on the ground due to stress reactions, and all four limbs of the animal will be marked with ink, resulting in multiple footprints on the gait paper, making it impossible to distinguish the footprints of the surgical limb from the non-surgical limb. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a limb marking cage based on gait analysis, so as to avoid confusion between the footprints of the operated limb and other limbs when the animal is undergoing a gait analysis experiment.
