Biopsy Robot Design for Breast Cancer Identification

Abstract

Nowadays breast cancer is one of the main problems that affect women worldwide. In Mexico, this disease is considered the second cause of death of productive age women, and the first cause of death worldwide. This death rate, as well as the incidence, have been ascending in the last years; however, the correct interpretation of test analysis could play a key part in the process. Biopsy procedures are successful only for 78% of cases, which leaves 22% of patients in danger of receiving wrong diagnoses which include false negatives, leading towards late treatment and therefore fewer survival possibilities. This project aims to increase the successful biopsy results by implementing the usage of biomedical robotics. The development consists of a Delta type robot, equipped with infrared sensors for cancerous breast pathology localization, trucut type biopsy needle, thermal image projection, artificial intelligence for optimum trajectory and positioning over the patient. This equipment offers a live detection with infrared technology and a precise incision controlled by the health professional. Therefore, this system offers a more accurate precision reaching the tumour, achieving a better extirpation of suspicious tissue for histopathological analysis, reducing the number of false negatives and, therefore, acting directly over the death rate.
