Phantom model for simulating clinical tumor thermal ablation treatment

Abstract

The invention discloses a phantom model for simulating clinical tumor thermal ablation treatment. The formula comprises the following components of acrylamide, methylene acrylamide, temperature-sensitive ink with 5% v / v, ammonium persulfate with 0.14% w / v, TEMED with 0.1% v / v, wherein the w / v of acrylamide and methylene acrylamide is 7%, the mass ratio of acrylamide to methylene acrylamide is 19:1, and the color of the temperature-sensitive ink can be changed from colorless to pink when the temperature of the temperature-sensitive ink is greater than or equal to 60 DEG C. The elasticity and texture of the phantom model are similar to those of liver tissue, the position of an ablation needle or a puncture needle in the phantom model can be clearly positioned and displayed in an ultrasonicimage, obvious color change occurs when the ablation temperature reaches 60 DEG C or above, and the phantom model can be used for evaluating the ablation range of thermal ablation. The phantom model has the advantages of strong plasticity, simple formula and convenient preparation, and can be used for simulating clinical tumor thermal ablation treatment.

Description

technical field [0001] The invention belongs to the field of medicine and relates to the field of thermal ablation under the guidance of ultrasound in interventional therapy, in particular to a phantom model for simulating clinical tumor thermal ablation therapy. Background technique [0002] Thermal ablation is a commonly used method for local treatment of liver tumors in clinical practice. It has the advantages of good curative effect, less trauma, and fewer complications. The basic operation is to kill tumor cells by inserting the ablation needle into the tumor and generating a large amount of heat. Studies have shown that maintaining the ablation temperature at 54°C for three minutes or at 60°C can achieve complete tumor inactivation immediately. In order to achieve radical treatment of tumors and minimize tumor progression, in the process of local thermal ablation, it is often necessary to perform multi-point overlapping ablation according to the size and shape of the ...
