Patent ID: 8241301

Claim:
A puncturing needle guiding device comprising: i) a needle-entering angle guide, adapted to be rotatably connected a needle when placed in said guide via a connector, further including: i.a) an angle reference line (N) vertical to a surface where the needle enters, and i.b) an indicator of said guide, including a needle-entering angle indicating plate, for indicating an intersected angle between an actual enter direction of the needle and the angle reference line (N), ii) a needle-entering layer leveler, sidely affixed to the guide, further comprising ii.a) an indicator of said layer leveler, including a scanning layer leveling benchmark, for indicating a deviatingly rotated angle of a rotating plane of the needle, wherein a deviating angle rotating axis of the indicator of said layer leveler is parallel to the guide (W), and iii) a reference line leveler, making the angle reference line of the guide (W) on the same plane of a hammer weight line, further comprising: iii.a) an indicator of said line leveler, including an angle indicating base plate, wherein a deviatingly rotated axis y of the indicator of said line leveler is perpendicular to the deviating angle rotating axis; and iv) a level benchmark, making a horizontal line of the rotating plane parallel to a needle-entering layer, and v) a top open rectangular casing, including a top opening and is affixed sidely to the guide, with the layer leveler and the line leveler (Y) disposed within, wherein the indicator of the layer leveler and the indicator of the line leveler are exposed in the top opening mounted with a transparent cover.
