【摘要】 目的 :探讨电刺激狗盆神经诱发阴茎勃起的最佳参数。方法 :用窄脉冲电压信号刺激狗盆神经。结果 :刺激前后阴茎海绵体压力分别为 ( 1.13± 0 .2 7)kPa和 ( 10 .79± 2 .61)kPa ,差异具有显著性 (P <0 .0 1) ;海绵体压力达到或大于平均动脉压的 80 %时阴茎已充分勃起 ,能够导致阴茎充分勃起的最弱电刺激参数为 :脉冲电压幅值 ( 2 .9± 0 .9)V ,频率 ( 2 .8± 7.9)Hz ,脉冲宽度 0 .1ms。结论 :电刺激盆神经是诱发阴茎勃起的有效方法之一 ,研制盆神经刺激器有助于男性性功能障碍的治疗更多还原

【Abstract】 Objective:The study was to explore the best parameters that can induce penis erecting by electrical stimulation on dog’s pelvic nerve.Method:Narrow pulses of electric signal were used to stimulate dogs pelvic nerve.Results:It was found that before and after stimulation,penis intercavernous pressure was 1.13 ±0.27kPa and 10.79±2.61kPa respectively,with significant difference(P<0.01).When the inter cavernous pressure was equal to or higher than eighty percent of average arterial blood pressure,the penis erected fully.The lowest electrical parameters of stimulation that can induce penis erection were:duration 0.1ms,frequency 28± 7.9 Hz,intensity 2.9 ± 0.9 V.Conclusion:The study manifests that electrical stimulation to dogs pelvic nerve is one of the valid ways that can induce penis erection and instruments for pelvic nerve stimulation should be developed and manufactured to help cure male sexual disorders.更多还原
