目的设计应用节段性兔股薄肌肌皮瓣构建再造阴茎、重建勃起功能的动物模型.方法依据肌亚部原则,近似二等分纵向完全劈开兔股薄肌,以前部肌束作为功能单位和皮瓣血供来源,植入硅胶假体作为支撑,构建阴茎再造的动物模型.应用多道生理信号采集处理系统刺激再造阴茎活动,并同步检测复合肌肉动作电位.结果通过电刺激兔再造阴茎根部的神经,可使前部肌束收缩,引起阴茎形态的相应改变,当肌束发生强直收缩时,再造阴茎上翘幅度最大,并可维持翘起状态数秒,较满意地模拟了阴茎的勃起动作.结论应用节段性兔股薄肌肌皮瓣构建的再造阴茎动物模型,较满意地重建了阴茎勃起功能,达到了兼顾改善阴茎外观与保留肌肉收缩功能的要求,具有较好的临床应用前景.

Objective To design an animal model for the reconstruction of penile erectile function with segmental gracilis musculocutaneous flap. Methods The rabbit gracilis muscle was split longitudinally into two approximately equal halves completely according to the principles of muscle compartmentalization. An animal model was designed for the reconstruction of erectile function with segmental musculocutaneous flap based on the anterior gracilis muscle bundle, with a silicone stick implanted as a supporter.A multi-channel physiological signal acquisition and processing system were used to stimulate the reconstructed penis and its CMAP was measured synchronously.Results When its nerve was electric stimulated, the muscle bundle contracted, which made the reconstructed penis moving accordingly.It satisfactorily simulated the way of a normal penis' s erection. Conclusions The reconstructed penis with rabbit segmental gracilis musculocutaneous flap according to the principles of muscle compartmentalization has achieved the erectile function satisfactorily.It has met the requirements of both improving reconstructive penis' s appearance and retaining muscle' s contractive function.
