本文提出了一种独特的装置（变体），提供紧急血流停止。该设备允许结合两种操作：穿刺组织和在结构上放置夹子（迄今为止，世界上没有任何设备在外科实践中提供这种组合）。该装置的功能是基于单向和双向形状记忆效应（SME和TWSME对应）。该装置允许在人体温度或更高的温度下，由于直接形状记忆效应的表现而停止血液流动。冷却时，由于TWSME，设备显示夹支部分打开。之后，夹子可以简单地取出，没有任何创伤患者。确保在要求的温度范围内进行热机械性twsme诱导。为了提供该装置去除马氏体的可能性，采用了twsme诱导。新装置的应用排除了结构活动的必要性，因此，减少了患者在手术干预过程中创伤的可能性。利用这种新装置进行结构剪切的方法不需要特殊的技术和昂贵的高科技设备。该装置也可用于组织固定。该装置用于治疗7例患者，表现出良好的功能可能性。
This paper presents a unique device (variants), providing emergency arrest of blood flow. The device allows combining two manipulations: piercing of tissues and laying a clip on structure (hitherto there was no device in the world surgical practice providing such combination). The device functioning is based on one-way and two-way shape memory effects (SME and TWSME correspondingly). The device allows to stop the blood flow due to the manifestation of direct shape memory effect under human body temperature or higher if needed. When cooling the device manifests partial opening of clip branches due to TWSME. After that the clip can be removed with simplicity without any patient in trauma. Thermomechanical TWSME-inducing in the required temperature range is ensured. In order to provide the possibility of the device removing the martensitic TWSME-inducing was applied. Application of the new device excludes a necessity of structure mobilisation, and therefore, decreases the possibility of patient in trauma in the process of surgical intervention. The method of clipping structures using the new device does not demand special virtuous skills and high-tech expensive equipment. The device can also be used for tissue fixation. The device was applied in treating of seven patients and manifested fine functional possibilities.
