The invention relates to the field of medical equipment testing and provides a lower-limb blood vessel stent physiological deformation simulation device used for testing the fatigue condition of a lower-limb blood vessel stent. The lower-limb blood vessel stent physiological deformation simulation device comprises a pelvic movement reference point track generator, a tibia movement reference point track generator, a human body lower limb skeleton model, a blood vessel and a supporting assembly. The first end of the human body lower limb skeleton model is connected with the pelvic movement reference point track generator, and the second end of the human body lower limb skeleton model is connected with the tibia movement reference point track generator. The blood vessel is arranged on the surface of the human body lower limb skeleton model, and the lower-limb blood vessel stent is arranged in the blood vessel. The supporting assembly comprises a bottom plate and a vertical column, and the vertical column is arranged on the long and wide face of the bottom plate. The pelvic movement reference point track generator is fixed to the bottom plate and the vertical column, the tibia movement reference point track generator is fixed to the bottom plate, and the human body lower limb skeleton model is fixed to the vertical column. Compared with the prior art, the lower-limb blood vessel stent physiological deformation simulation device can more reflect the real stress condition of the lower-limb blood vessel stent.
Description
technical field [0001] The invention relates to the field of medical device testing, in particular to a device for simulating physiological deformation of a lower limb vascular stent. Background technique [0002] Vascular interventional surgery is the main means of treating cardiovascular diseases, and vascular stents are an important factor in determining the effect of surgery. For the design of lower extremity vascular stents, in addition to the complications associated with intervention in the human body, it is also necessary to consider the fatigue fracture of vascular stents and the fatigue caused to blood vessels under the action of alternating stress generated by the reciprocating movement of the legs. damage. At present, the design of lower extremity vascular stents is mostly in the stage of theoretical research and computer finite element analysis simulation, and a fatigue test device for lower extremity vascular stents is needed to provide a realistic basis for t...
