摘要目的:比较采用不同钻速进行电钻钻孔操作时,骨质局部温度的变化,获取在微创隧道人工耳蜗植入手术中电钻钻孔操作的安全参数。方法采用外形近似的新鲜猪肋骨块,在两块骨块的截面依次安放3枚热敏电阻(Pt100)并固定,分别于皮质骨表面,距离横截面1.5 mm处进行钻孔操作。按照钻速由低至高,人为分为100、1250、7000、10000、20000、30000和40000 r/min,每个钻速重复实验6次,记录钻孔时的温度变化。比较不同钻速钻孔时骨质升温的差异。结果采用100 r/min钻孔时,钻孔局部骨质的平均升温(3.81±1.47)℃,采用1250 r/min钻孔时,骨质平均升温(11.57±4.32)℃,两者间差异无显著性(P=0.130);在钻速为7000 r/min钻孔时,骨质升温(18.01±3.62)℃,与10000 r/min钻速组的(43.09±10.05)℃比较,两者差异有统计学意义( P=0.000);当转速高于10000 r/min时,提高转速后局部骨质升温的变化无显著性差异。结论在本研究条件下,使用低钻速100 r/min和1250 r/min进行钻孔操作时,骨质局部升温较小,当钻孔局部要求的温度不能过高时,应选择低钻速进行操作。 Objective To compare changes in bone temperature during the drilling using different drill speeds and to get the safe parameters of drilling operation in minimal invasive cochlear implant. Methods Fresh pig ribs bone samples with similar shape were used in this study.Three thermistors (Pt100) were fixed in the transverse section of the bones.There were seven drilling speeds groups which included 100, 1250, 7000, 10 000, 20 000, 30 000 and 40 000 r/min.Drilling were used to create holes at the location 1.5 mm from the thermistors with different speeds.Changes in temperature were recorded. Results The mean temperature raise when drilling in 100 r/min was (3.81 ±1.47) ℃ and in 1250 r/min was (11.57 ±4.32) ℃, without statistical difference (P=0.130).The mean temperature raise when drilling in 7000 r/min was (18.01 ±3.62) ℃ and in 10 000 r/min was (43.09 ± 10.05) ℃, with statistically difference (P=0.000).There were no significant differences in temperature raise when the drilling speeds were higher than 10 000 r/min. Conclusions Within the limitations of this study, drilling bones in 100 r/min and 1250 r/min generates less heat.When the local temperature be limited, low speed drilling should be used in drilling the bone.
