本文实验分析了胆道材料的力学特性,提出了利用液体弹性波在肝胆系统内入射反射的交互作用来松动术后残余结石。论证了液体弹性波在肝胆管内的波速。当忽略液体的压缩性后,所得的结果与著名的Moens-Korteweg公式相同,据此,可确定出波速的数量级,从而得出附加脉动的概念。 新型电子型振荡仪采用外加调制振荡强化了这种脉冲性,使脉动排石的理论效应能在实际上加以主动地控制和调节。在此基础上设计的电子振荡仪采用了具有自动温度补偿及恒流源的多谐振荡器作为振荡源,单结晶体管组成的调制脉动源则在液体弹性波的波峰上产生强化脉动,通过输出电路及灵敏的电—液转换器输送液体弹性波。 经过三年多的研究和临床实践,本研究成果已于1980年10月29日通过鉴定,确认“是治疗术后胆道残余结石的一个首创”。
In this paper, we analyzed the mechanical properties of the biliary material experimentally and proposed the use of liquid elastic waves in the liver and gallbladder system to reflect the interaction of the incident to loosen residual stones. The wave velocity of liquid elastic waves in the hepatobiliary duct is demonstrated. Ignoring liquid compressibility, the result is the same as the well-known Moens-Korteweg formula, by which the magnitude of the wave velocity can be determined and the concept of additional pulsations can be derived. The new electronic oscillator uses an additional modulation oscillation to strengthen this pulse, so that the theoretical effect of pulsating row of stones can actually be actively controlled and adjusted. On the basis of this, the electronic oscillator designed with multivibrator with automatic temperature compensation and constant current source as the oscillation source, the modulation pulsation source composed of single-junction transistor generates enhanced ripple on the wavefront of the liquid elastic wave, Electrical circuits and sensitive electro-hydraulic transducers deliver liquid elastic waves. After more than three years of research and clinical practice, the results of this research were approved on October 29, 1980 and confirmed that “it is an initiative to treat postoperative residual biliary stones.”
