Guided puncturing needle and puncturing guiding method
First Claim
1. 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, andi.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 comprisingii.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), andiii) 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, whereina 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, andv) 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.

Abstract
A guide puncturing needle which is integratively used with a scanning and detecting device, such as CT, MRI or the like, and provides puncturing, biopsy, injection, implanting, and the physical diagnose and therapy, such as RF, microwave, freezing, laser and the like, and a puncturing guide method for applying the puncturing needle to puncture are provided. Since the guide puncturing needle is provided with a needle-entering angle guide means (2), a puncturing layer levelling component (31), a needle-entering reference line levelling component (32), whether the CT gantry and the MRI scanning layer are at any angle, the actual needle-entering layer is always adjusted to just superpose to the CT scanning layer, the actual needle-entering angle is always just the same as the needle-entering angle needed for the scanning and detecting device, thus allow the puncturing needle to arrive at the focus point exactly accurately.
