A puncture planning path correction method and device, the method comprising: on the basis of an initial planning path, determine an initial entry point on the skin in a puncture region and set the initial entry point as a marker point (201)； perform two successive CT scans of the puncture region to obtain an initial CT image and a second CT image (202)； mark on the initial CT image an initial planning path； acquire position information of a mark point in the second CT image (203)； perform registration on the initial CT image and the second CT image； on the basis of the position information of the marker point, determine the position of the marker point in the initial CT image after registration (204)； obtain a distance vector of the marker point to the initial planning path (205)； utilizing the distance vector of the marker point to the initial planning path, perform a translation transformation of the initial planning path, and set an intersection point of the transformed path and the puncture region on the skin as an actual entry point； on the basis of the actual entry point, and in accordance with the length of the initial planning path, determine a target point, and obtain a corrected puncture planning path (206). The puncture planning path correction device comprises: a marker point determining unit (401), a CT scanning unit (402), an initialization unit (403), a registration unit (404), a translation vector acquisition unit (405) and a correction unit (406).La présente invention concerne un procédé et un dispositif de correction de trajectoire de planification de ponction, le procédé comprenant : sur la base d'un trajet de planification initial, la détermination d'un point d'entrée initial sur la peau dans une région de ponction et la définition du point d'entrée initial en tant que point de repère (201) ； la conduite de deux scans TDM successifs de la région de ponction pour obtenir une image TDM initiale et une deuxième image TDM (202) ； le marquage sur l'i
