The utility model relates to the field of renal artery and vein puncture simulation experiments, in particular to a simulation device used for renal artery and vein puncture and intravascular treatment.

Background technique

The kidney is an important organ of the human body. Its basic function is to generate urine to remove metabolites and certain wastes and toxins from the body. At the same time, it retains water and other useful substances through reabsorption, such as glucose, protein, amino acids, sodium ions, Potassium ions, sodium bicarbonate, etc., to adjust water and electrolyte balance and maintain acid-base balance, ensure the stability of the body's internal environment, and enable metabolism to proceed normally.

There are renal arteries and renal veins in the kidneys, and both renal arteries and renal veins are called blood vessels. Endovascular interventional therapy uses high-tech equipment such as video equipment, computers and monitors to puncture the blood vessels at the kidney, and then use catheters and guide wires to penetrate the blood vessels in the patient's body for angiography, embolization, perfusion, repair, expansion, and dredging.
