摘　　要：目的对比不同消毒方式对腔镜器械的损伤,分析最优灭菌方式。方法采用临床上常用的压力蒸汽法、环氧乙烷法和过氧化氢低温等离子体法在一年内分别对三组各10把腔镜器械分离钳进行100次灭菌处理,然后对不同方式消毒后的器械进行相关特征(包括关节的平顺度、钳头二片的吻合度、杆部与柄部的腐蚀度与粗糙度、钳头与柄部的硬度)的测评及对比。结果组间分离钳钳头二片吻合度、杆部和柄部的腐蚀度存在显著性差异(P<0.05)。蒸汽压力法、环氧乙烷法和低温等离子体法灭菌前后杆部粗糙度变化分别为(0.465±0.041)、(0.086±0.009)和(0.762±0.082)μm,组间存在显著性差异(P<0.001),钳头硬度变化分别为(-59.1±12.2)、(-10.7±2.5)和(-26.8±5.8)HV0.2,组间也存在显著性差异(P<0.001)。结论压力蒸汽灭菌法对器械整体损伤最大,其次为等离子灭菌法,环氧乙烷灭菌法对器械损伤最小。Objective To compare the damage of different sterilization methods to endoscopic surgical instruments(ESI),and to get the best sterilization method to related equipments.Methods Each group’s ten separation-forceps belonging to the ESI were respectively processed with 100 times by three popularly used sterilization methods including pressure-steam sterilization(PsS),ethylene-oxide sterilization(EoS)and low-temperature-plasma sterilization of hydrogen peroxide(LtpSHP)within one year,then the relevant characteristics the instruments after disinfection in different ways including the smoothness of the joint,the anastomosis of forcep-head,the roughness and corrosion of stem and handle,and the hardness of head and handle were evaluated and compared among three groups.Results The anastomosis of forcep-head and the corrosion of stem and handle were significantly different among three groups(P<0.05).In addition,the changes of stem’s roughness compared to before sterilization were 0.465±0.041μm,0.086±0.009μm and 0.762±0.082μm with the PsS,the EoS and the LtpSHP methods respectively,which were significantly different among three groups(P<0.001).And the changes of the forcep-head’s hardness compared to before sterilization were-59.1±12.2 HV0.2,-10.7±2.5 HV0.2 and-26.8±5.8 HV0.2 respectively,which were also significantly different among three groups(P<0.001).Conslusion The PsS method caused the most damage to the ESI,the middle one was the LtpSHP method,and the EoS method had the smallest damage to the ESI overall.
