Abstract
The types of injuries and types of striking elements were analyzed, the conditions of patients requiring urgent surgical intervention were assessed. The possibilities of existing means of diagnosing fragments in the patient's body were analyzed, and it was concluded that for non-X-ray contrast fragments, the proposed method of mechanical contact with a special flexible and elastic probe is appropriate and effective.A special tool for examining wound canals has been developed, consisting of a flexible probe for individual use and a handle-holder with a microphone capsule, the membrane of which is directly connected to the probe and reacts to mechanical contact with an obstacle, and the capsule itself is directly connected to the oscilloscope through a signal amplifier . which has spectral signal processing circuits.The problem of the interaction of the elastic contact of a non-rigid element with a fragment located in a viscous medium is set, provided that the properties of the medium are not constant. Typical solutions of this problem for various types of fragments and parameters of the contacting element itself are presented. A picture of the noise emission accompanying the contact is shown.The functional dependence of noise emission parameters on the shape and type of the foreign object in the wound canal was revealed. The expediency of using the frequency-amplitude characteristic of noise radiation as a controlled parameter has been proven. A conclusion was made about the functional conditioning of the width of the signal spectrum and basic frequencies at the time of mechanical contact with a foreign object in the wound, depending on its shape and type; it was established that the use of an oscilloscope with a spectral analysis channel allows for the fairly accurate identification of a non-radiocontrast foreign object in a wound.
分析了损伤类型和打击要素类型,评估了需要紧急手术干预的病人的情况。分析了诊断病人体内碎片的现有方法的可能性,得出结论认为,对于非 X 射线对比碎片,建议使用特殊的柔性弹性探针进行机械接触的方法是适当而有效的。已开发出一种用于检查伤口管道的特殊工具,它由一个供个人使用的柔性探头和一个带麦克风胶囊的手柄座组成,麦克风胶囊的薄膜直接连接到探头上,并对与障碍物的机械接触做出反应,胶囊本身通过一个信号放大器直接连接到示波器上,示波器上有频谱信号处理电路。文中介绍了不同类型碎片和接触元件本身参数的典型解法。揭示了噪声发射参数与伤口管道中异物的形状和类型之间的函数关系。使用噪声辐射的频率-振幅特性作为控制参数的便利性已得到证实。根据伤口异物的形状和类型,对机械接触伤口异物时的信号频谱宽度和基本频率的功能调节做出了结论;确定了使用带有频谱分析通道的示波器可以相当准确地识别伤口中的非辐射异物。
