摘　　要：发散式冲击波作为一种新兴的医疗技术,在骨科、运动医学等领域具有独特优势,然而目前缺少统一的指标用于表征其临床治疗强度。在分析了发散式冲击波产生原理的基础上,提出将能流密度作为其临床治疗强度的评价指标。搭建高精度水下动态压力测量系统,对发散式冲击波的压力波形进行测定,再利用激光多普勒测振仪对波源的振动波形进行精准测量,对比两者,验证了实验系统所测压力波形的正确性。最后根据测得的压力波形计算能流密度,将其作为冲击波强度的表征指标,有效减少了同时调节多个参数的盲目性。该研究对其临床应用具有重要意义。As a new medical technology,radial shock wave therapy has unique advantages in orthopedics,sports medicine and other medical fields.However,an unified index is needed to evaluate the intensity of clinical treatment of radial shock wave therapy.Based on the principle of radial shock wave generation,the energy flow density was advanced as an index for evaluating the intensity of clinical treatment.High precision underwater dynamic pressure measurement system was established to measure the pressure waveform.Then the laser Doppler vibration measurement was used to measure the vibration wave of the wave source accurately.The correctness of the pressure waveform measured through the experimental system is proved by comparing the two kinds of waveform.Finally,the energy flow density was calculated according to the measured pressure waveform,which is helpful to effectively reduce the blindness because of simultaneous adjustment of multiple parameters,and it was advanced as an index for evaluating the intensity of shock wave,which has positive guiding significance for its clinical application.
