采用动物实验方法试对国产RGF 2 0 0 0温控消融仪的可靠、有效及实用性作出初步评估。对 6只健康杂种狗 ,使用国产RGF 2 0 0 0温控消融仪与进口IBI 15 0 0T温控消融仪 ,分别在二尖瓣环、三尖瓣环、右心室、房室结及右心房等处用不同的温度消融放电 ,观察组织大体和镜下病理学改变 ,比较两种消融仪消融的效果。结果 :RGF 2 0 0 0温控消融仪能够稳定达到预设温度 ,且在同等条件下两种温控消融仪对组织的损伤大小及程度并无差别 ,两组消融的并发症均较低。结论 :RGF 2 0 0 0温控消融仪性能可靠 ,消融效果较好且稳定 ,与同类进口温控消融仪相比并无明显差别 ,能够扩展到临床应用。
The animal experiment method was used to make a preliminary assessment of the reliability, effectiveness and practicability of the domestic RGF 2000 control ablation instrument. Six healthy mongrel dogs were treated with domestic RGF 2000 temperature-controlled ablation instrument and imported IBI 1500 T-ablation instrument respectively in mitral annulus, tricuspid annulus, right ventricle, atrioventricular node and right atrium And other places with different temperature ablation discharge, observe the gross and microscopic pathological changes in tissue, ablation of two ablation instruments compared the effect. Results: The temperature-controlled ablation instrument of RGF 200 can reach the preset temperature stably. Under the same conditions, the two kinds of temperature-controlled ablation instrument did not affect the size and extent of the injury, and the complications of ablation were lower in both groups. Conclusion: The RGF 2000 controlled ablation instrument has reliable performance, good ablation effect and stability. Compared with similar imported temperature ablation instrument, there is no significant difference and can be extended to clinical application.
