温度メモリ・荷重計測機能を有する手術訓練用心臓モデルを用いた焼灼深さ推定

抄録

A hydrogel heart model with a temperature memory function and a strain sensor was fabricated for quantitative evaluation of cauterization depth using an ablation catheter. The ablation depth was related to heat temperature, heating time, and input load. The hydrogel heart model elaborating the heat properties of the human heart was fabricated, and input load was evaluated by incorporating a flexible strain sensor. The cauterization depth was measured by the color analysis of the cauterized model with temperature memory function. An evaluation result confirmed a proportional relationship between the cauterization depth and heat temperature, heating time, and input load in the fabricated model.
