METHOD AND DEVICE FOR NEEDLE ALIGNMENT Russian patent published in 2014 - IPC A61B17/34 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine and may be used in the process of a percutaneous intervention in a combination with a visualisation tool to control an angular attitude of a needle-shaped object when it moves from the given injection point to a given target point in the body. The device comprises a bearing unit to function as a bearing of a guide unit. The bearing unit comprises a pair of parallel reference planes that are at least partially detectable by the visualisation tool. The guide unit provides a leading axle substantially perpendicular to a pair of the parallel reference planes. The needle-shaped object can be translated along the leading axle. The angular attitude of a visualisation plane generated by the visualisation tool, determines a measuring reference for the angular attitude of a pair of the parallel reference planes. When aligning the pair of the parallel reference planes with the visualisation plane, the leading axle is found in a coincidence with a trajectory from the injection point to the target point.

EFFECT: device improvement.
