摘要： A point-of-care seed stranding device for automating assembly of brachytherapy seed strands for implantation in patients. The device includes a number of features to reduce the potential for mistakes by the user, as well as to reduce the potential for damaging the radioactive seeds during the stranding process. Tactile feedback may be provided to prevent exertion of too much force in the packing step of the stranding process, as well as to indicate that the seed and/or strand cartridges are empty and need to be replaced. The device may also include a mechanism for holding seeds or spacers in place to allow automated packing of seeds or spacers having corresponding geometries. The device may also be provided with a seed counter which can be employed to preset the number of seeds in a strand and which disables the device from dispensing or packing additional seeds once the preset number of seeds has been packed into the strand. Also, methods for automated assembly of seed strands including the steps of setting the number of seeds, dispensing seeds and spacers, packing seeds and spacers and transferring assembled strands to another device.

摘要翻译： 一种用于自动装配近距离放射治疗种子股的护理种子绞合装置，用于植入患者。 该装置包括许多特征，以减少使用者的错误的可能性，以及减少在绞合过程中损坏放射性种子的可能性。 可以提供触觉反馈以防止在绞合过程的包装步骤中施加过大的力，并且指示种子和/或线束筒是空的并且需要更换。 该装置还可以包括用于将种子或间隔物保持在适当位置以允许自动包装具有相应几何形状的种子或间隔物的机构。 该装置还可以具有种子计数器，该种子计数器可用于预定股线中的种子数量，并且一旦预定数量的种子已经被包装到股线中，该种子计数器就禁止装置分配或包装额外的种子。 此外，种子股线的自动装配的方法包括以下步骤：设定种子数量，分配种子和间隔物，包装种子和间隔物并将组装的股转移到另一装置。
