Abstract
The technical and economic benefits of the use of radiotracers have been recognized worldwide by the industrial sector; however, this technique continues to be underutilized, not only in countries that do not have facilities to produce radionuclides, but also in those where the necessary equipment and its timely availability are lacking. This paper presents the conceptual design and fabrication of the tooling necessary to obtain the components of the elution assemblies of 99mTc / 99Mo generators. Technetium 99m is the most widely used radioisotope for diagnostic and therapeutic purposes in nuclear medicine. It can bind to a number of specific molecules, making it possible to diagnose many diseases, including certain types of cancer. Its implementation is justified due to the high costs of the components necessary for the development of elutions in patients, the difficulties in importing this equipment, and the impact and sensitivity it has on the health of patients. In order to respond to this problem, first a bibliographic review of the advances obtained worldwide regarding these issues is carried out. The calculations and designs of a set of cutting, bending and sharpening devices are developed, together with the plastic injection molds, which allow obtaining the necessary accessories for the correct execution of the elutions. Through the use of this tooling, the importation of needles for the elutions is substituted, reducing foreign currency expenses, guaranteeing technological sovereignty and opening possibilities for exportation.
Resumen
Los beneficios técnicos y económicos del empleo de los radiotrazadores han sido mundialmente reconocidos por el sector industrial; sin embargo, esta técnica continúa subutilizada, no solo en los países que no poseen instalaciones para producir radionúclidos, sino también en aquellos donde no existe el equipamiento necesario y su disponibilidad oportuna. El presente trabajo expone el diseño conceptual y la fabricación del herramental necesario para obtener los componentes de los conjuntos de elución de generadores 99mTc / 99Mo. El tecnecio 99m es el radioisótopo más utilizado con fines de diagnóstico y terapéutico en la medicina nuclear. Puede adherirse a varias moléculas concretas, lo que permite diagnosticar muchas enfermedades, entre ellas determinados tipos de cáncer. Se justifica su realización, debido a los altos costos de los componentes necesarios para el desarrollo de las eluciones en pacientes, las dificultades para la importación de estos equipamientos, y el impacto y sensibilidad que tiene en la salud de los pacientes. Para dar respuesta a esta problemática, se realiza primero una revisión bibliográfica de los avances obtenidos a nivel mundial respecto a estos temas. Se desarrollan los cálculos y diseños de un conjunto de dispositivos de corte, doblado y afilado, conjuntamente con los moldes de inyección de plástico, que permiten obtener los accesorios necesarios para la correcta ejecución de las eluciones. Mediante el empleo de este herramental, se sustituye la importación de las agujas para las eluciones, disminuyendo gastos de divisas, se garantiza soberanía tecnológica y se abren posibilidades para la exportación.
