Abstract

Est divulgué, un système de robot chirurgical pour réaliser une ponction, comprenant un ensemble de commande, une table de support mobile (10), un bras à ultrasons (20), un ensemble de détection à ultrasons (30) et un ensemble de ponction (40), le bras à ultrasons (20) présentant une première extrémité de raccordement (21) et une première extrémité de travail (22) ; l'ensemble de détection à ultrasons (30) comprend une sonde à ultrasons (31) ; l'ensemble de ponction (40) comprend un mécanisme de réglage de posture (41), un mécanisme d'insertion d'aiguille (42) et une aiguille de ponction (43) ; le mécanisme de réglage de posture (41) a une seconde extrémité de raccordement et une seconde extrémité de travail ; l'ensemble de détection à ultrasons (30) est utilisé pour effectuer une détection pour un patient à ponctionner et pour obtenir un plan d'imagerie ultrasonore ; la sonde à ultrasons (31) est reliée à la première extrémité de travail (22), la seconde extrémité de raccordement est reliée à la première extrémité de travail (22), et le mécanisme d'insertion d'aiguille (42) est relié à la seconde extrémité de travail ; et une extrémité de l'aiguille de ponction (43) est serrée sur le mécanisme d'insertion d'aiguille (42), et l'axe central de l'aiguille de ponction (43) est situé dans le plan d'imagerie ultrasonore. L'utilisation de cette solution technique résout le problème selon lequel un robot chirurgical pour réaliser une ponction dans l'état de la technique est encombrant en termes de taille et de structure et ne peut pas être actionné ni déplacé dans la plage d'un petit espace, ce qui rend difficile l'obtention d'une coordination flexible pour déplacer la sonde à ultrasons (31) et l'aiguille de ponction (43).
