Monitoring of temperature changes and accurately determining the moment of electrode removal during open heart operations is not well recognized.
We investigated the temperature fields distribution in the biological tissues affected by electrosurgery upon use of an infrared thermograph.
The dynamics of temperature distribution in the tissue was registered by the thermal imaging camera FLIR i7. Measurement of the temperature between electrode couples was carried out for two operation modes: coagulation (100% power) and coagulation (50% power).
The most important result of the applied method of temperature monitoring is a determination of the moment for electrodes removal that ensures the avoidance of carbonization of the cardiac tissues during their ablation.
Temperature monitoring for connection of soft live biological tissues by welding allows the power to be fed in the amount sufficient for a formation of continuous ablation of the myocardium tissue.
在心脏直视手术中，对温度变化的监测以及准确确定电极移除时刻尚未得到充分认识。
我们使用红外热成像仪研究了电外科手术对生物组织温度场的分布影响。
通过FLIR i7热成像相机记录组织中温度分布的动态变化。针对两种操作模式（凝固模式，功率100%；凝固模式，功率50%）测量电极对之间的温度。
所应用的温度监测方法的最重要结果是确定电极移除时刻，以确保在心肌组织消融过程中避免心脏组织碳化。
通过焊接连接柔软的活体生物组织时进行温度监测，能够以足以形成心肌组织连续消融的量供给能量。
