An improved bladeless visible puncture needle (200), comprising a proximal handle part (202), a distal part (206), and a rod part (204) therebetween. The handle part (202) and the rod part (204) comprise aligned center shaft holes (242); the distal part (206) comprises a visible head (250). From a distal end to a proximal end, the visible head (250) may be divided into a top part (290), a spear-shaped part (280), a transition part (270), and a base part (260); the top part (290) comprises a top point (299) and a rotating wall (294) that axially extends from the top point (299) to the proximal end and is gradually enlarged in the transverse direction; the rotating wall (294) defines a hollow cone (296); the spear-shaped part (280) comprises a sweeping wall (284); the rotating wall (294) and the sweeping wall (284) extend to intersect each other so as to form a circular field of view (292); the sweeping wall (284) axially extends from the distal end to the proximal end and is gradually enlarged in the transverse direction; the spear-shaped part (280) comprises a first transverse part and a second transverse part, and the transverse size of the first transverse part is greater than that of the second transverse part; from the distal end to the proximal end, the ratio of the transverse sizes of the first transverse part and the second transverse part is gradually decreased.Aiguille de ponction (200) améliorée avec suivi visuel comprenant une partie de préhension (202) d'extrémité proximale et une partie d'extrémité distale (206), ainsi qu'une partie tige (204) venant entre, la partie de préhension (202) d'extrémité proximale et la partie d'extrémité distale (206) comprenant un orifice axial central (242) aligné, la partie d'extrémité distale (206) comportant, quant à elle, une tête de vision (250), laquelle, de l'extrémité distale à l'extrémité proximale, est divisée en une partie d'extrémité supérieure (290), une partie souple (280), une partie de transition (270) et u
