摘　　要：利用基于自制的射频能量设备对胃肠组织焊接算法进行优化研究,通过改变终止电压衰减量降低组织热损伤,以防止组织结痂、碳化现象发生。在实验过程中,通过控制单一变量,完成猪小肠焊接实验,对终止电压进行不同系数的衰减,分别取衰减量(DV)为60%、80%和100%,采用爆破压和热损伤评估焊接结果。经过爆破压和热损伤实验,得出以下结果:当调整电压衰减量为60%、80%和100%时,爆破压分别为9.387±0.423 7KPa、10.17±0.501 3KPa、9.286±0.427 9KPa;热损伤分别为0.376 9±0.019 48cm、0.398 8±0.010 25cm、0.419 4±0.015 01cm。实验表明,在合适的电压衰减系数算法下,热损伤及爆破压均有优化。在实际应用中,应该选取适当的电压衰减系数,才可保证管腔组织闭合后具有较大的爆破压和较小的热损伤范围。This paper optimizes the gastrointestinal tissue welding algorithm based on self-made RF energy equipment.By changing the attenuation of the termination voltage,the tissue thermal damage is reduced to prevent tissue crusting and carbonization.In the experiment,by controlling a single variable,the pig small intestine was welded,and the termination voltage was attenuated by different coefficients.The attenuation(DV)was 60%,80%and 100%,respectively.And thermal damage to evaluate the welding results.After the blasting pressure and thermal damage experiments,the following results were obtained.When the voltage attenuation was 60%,80%and 100%,the burst pressures were 9.387±0.423 7KPa,10.17±0.501 3KPa and 9.286±0.427 9KPa,respectively.The thermal damage was 0.376 9±0.019 48cm,0.398 8±0.010 25cm and 0.419 4±0.015 01cm,respectively.The research shows that under the appropriate voltage attenuation coefficient algorithm,thermal damage and burst pressure are optimized.In practical applications,appropriate voltage attenuation coefficient should be selected to ensure a large burst pressure after the lumen tissue is closed.And a smaller thermal damage range.
