Este estudio prospectivo evaluó la implementación de una novedosa plataforma robótica de un solo puerto en cirugía oncoplástica conservadora de mama para lesiones malignas. El criterio de valoración primario se centró en el éxito técnico, definido como el logro de márgenes de resección libres de tumor confirmados por histopatología de sección congelada intraoperatoria, con evaluación secundaria de los resultados estéticos y la puntuación de calidad de vida de los pacientes.

El enfoque de nuestro estudio es la aplicación de la tecnología robótica de un solo puerto en la cirugía del cáncer de mama. Su objetivo es abordar la eficacia y seguridad de la novedosa tecnología robótica de un solo puerto. en cirugía conservadora de mama para el cáncer de mama.

El reto experimental es mejorar la tasa de reconocimiento de los límites tumorales, reducir las tasas positivas de márgenes quirúrgicos y disminuir la incidencia de la operación de array. Realizamos la primera aplicación exitosa de robótica de un solo puerto en cirugía conservadora de mama para el cáncer de mama en China. Para empezar, utiliza la cámara robótica de un solo puerto para visualizar la zona quirúrgica.
