ABSTRACT

Introduction: The first generator for the application of radiofrequency lesions was created by Cosman in 1952, but its use in the field of pain did not occur until the 1970s. Since then, radiofrequency generators have improved in terms of safety, ergonomics, portability, and the possibilities for current administration.
Materials and methods: We conducted a market survey of radiofrequency generators available in our country for pain treatment and analysed their technical characteristics. The information was obtained from the manufacturers themselves and the technical descriptions of each product.
Results: The generators currently available include: Accurian™, Coolif™, Cosman G4™, Diros URF-3AP™, Inomed Lesion Generator LG2™, IonicRF™, LG4 RF Lesion Generator™, Multigen2 RF™, Neurotherm 2000IX™, RFE-4™, Spring2™, and Top TLG-20 multilesion ™. Each of these offers something unique compared to the others.
Conclusions: We have a wide range of radiofrequency generators, all of which are intuitive and safe, covering the entire spectrum of neuroablative and neuromodulatory techniques described. The specific needs of the users must be aligned with the options provided by the various generators.



RESUMEN

Introducción: El primer generador para la aplicación de lesiones por radiofrecuencia fue creado por Cosman en el año1952, pero su utilización en el campo del dolor no se produjo hasta la década de los 70. Desde entonces, los generadores de radiofrecuencia han ido mejorando tanto en seguridad, ergonomía y transportabilidad como en las posibilidades de administración de la corriente.
Material y métodos: Hacemos una prospección en el mercado de generadores de radiofrecuencia con aplicación para el tratamiento del dolor disponibles en nuestro país y analizamos sus características técnicas. La información la hemos obtenido de las propias casas comerciales y de las descripciones técnicas de cada producto.
Resultados: Los generadores disponibles actualmente son: Accurian™, Coolif™, Cosman G4™, Diros URF-3AP™, Inomed Lesion Generator LG2™, IonicRF™, LG4 RF Lesion Generator™, Multigen2 RF™, Neurotherm 2000IX™, RFE-4™, Spring2™, Top TLG-20 multilesión ™. Cada uno de ellos oferta algo diferencial respecto a los demás.
Conclusiones: Disponemos de una amplia gama de generadores de radiofrecuencia, todos ellos intuitivos y seguros, que cubren todo el abanico de técnicas neuroablativas y neuromoduladoras descritas. Las necesidades particulares de los usuarios deben ajustarse a las posibilidades que nos ofertan los distintos generadores.
