L'aiguille de ponction de biopsie (1) comprend une partie rotation (10), une partie ponction (11), une partie préhension (12) et des fibres optiques (14). Une partie inférieure de la partie préhension (12) est reliée à une partie supérieure de la partie ponction (11). La partie rotation (10) passe à travers la partie ponction (11) et la partie préhension (12). Les fibres optiques (14) sont disposées à l'intérieur de la partie rotation (10). Le dispositif de commande (2) comprend une partie commande (22) et une partie imagerie (20). La partie imagerie (20) comprend une partie électroluminescente (200) et une caméra (210) à l'intérieur de celle-ci. La partie électroluminescente (200) et la caméra (210) sont électriquement connectées à la partie commande (22). Deux extrémités du tube de guidage de lumière (3) sont reliées à des parties supérieures de la partie électroluminescente (200) et de la partie rotation (10), respectivement. La partie électroluminescente (200) est utilisée pour générer une lumière infrarouge, et la lumière infrarouge est transmise aux fibres optiques (14) à l'intérieur du tube de guidage de lumière (3) et de la partie rotation (10) afin de former un trajet optique. La partie commande (22) est utilisée pour commander la caméra (210) afin d'imager une partie corporelle éclairée par le trajet optique. Le système de commande (100) pour une aiguille de ponction de biopsie de la présente invention permet une acquisition en temps réel d'images d'une partie corporelle, et facilite la récupération d'un tissu pathologique au moyen d'une aiguille de ponction de biopsie (1) pour les médecins, bénéficiant ainsi au personnel médical et aux patients.
