Within the recent resurgence of brachytherapy as treatment for prostate cancer, many new devices have been conceived in the preparation of surgical brachytherapy equipment. Specifically, this work encompasses the automated preparation of preloaded surgical brachytherapy applicators or “needles” through the loading of radioactive seed elements and benign spacer elements. While traditionally a manual operation, current device methodology in this application revolves around semi-automatic mechanical interaction within the element loading procedure. Mechanical interaction can subject elements to damage, specifically seed elements due to thin metallic construct. Damage to elements within a loading system can result in failure of the performed brachytherapy treatment causing potential harm to the patient. Hesitancy in acceptance of these mechanical separation element loading devices can be attributed to the failure nature of these devices. This work seeks to solve the current issue of element damage through noninteraction while offering improvement through full automation of the loading procedure.
