Abstract

La présente invention concerne un système de guidage de ponction à haute résolution en temps réel. Le système de guidage de ponction comprend un hôte de système (2) et une aiguille de guidage capable de communiquer électriquement avec l'hôte de système (2). L'aiguille de guidage comprend un corps de support cylindrique ayant une extrémité proximale et une extrémité distale, une unité de détection à vision frontale disposée sur une face d'extrémité de l'extrémité distale du corps de support, une unité de détection à vision latérale disposée sur la surface périphérique du corps de support et proche de l'extrémité distale du corps de support, et une unité de connexion pour faire communiquer électriquement l'unité de détection à vision frontale et l'unité de détection à vision latérale avec l'hôte de système (2). Un canal de travail (10) est en outre formé dans le corps de support. Le système de guidage de ponction peut résoudre efficacement le problème d'incapacité à effectuer une imagerie à haute fréquence et à haute résolution sur un tissu profond en raison du fait que le dispositif de ponction guidée par ultrasons existant peut réaliser une surveillance et donner des indications uniquement à l'extérieur du corps ; par intégration d'une détection à vision frontale, d'une détection à vision latérale et du canal de travail (10), non seulement une imagerie d'une région devant un corps d'aiguille mais également une imagerie dans une direction à vision latérale du corps d'aiguille peuvent être obtenues, la direction et la précision d'image/d'injection peuvent être guidées et observées en temps réel.
