摘要： The invention relates to a device for guiding a medical needle, including said medical needle (1) and an insert (2) that is rotatably, translatably, and slidably arranged in the needle (1), wherein said device is characterized in that the insert (2) has, in the free state thereof, a curved distal portion (21), and in that the needle has at least two regions (11, 12), the mechanical behaviors of which are different, wherein the mechanical behaviors of each region (11, 12) and of the curved distal portion (21) of the insert are selected such that a movement of the insert (2) into the needle (1) causes a local deformation of the needle and/or of the insert. The invention also relates to a method for manufacturing said device.
