Needle guiding system, a needle guide and a method for using the needle guiding system in guiding a needle for needle insertion of a patient

A method of using a needle guiding system for guiding a needle for needle insertion of a patient, the needle guiding system comprising a marking device and a needle guide, wherein the marking device comprises a base, an angle scale having angle markings indicating angle positions of an imaging probe with respect to a plane of the base and an angle indicator adapted to indicate a probe angle on the angle scale, wherein the angle indicator is configured to move in tandem with the imaging probe, and wherein the needle guide comprises a guiding angle scale having guide angle markings corresponding to the angle markings of the marking device for indicating the angle positions of the imaging probe and an insertion slot for aligning a needle to an insertion site, wherein the base of the marking device comprises at least one protrusion and the needle guide further comprises at least one opening corresponding to the at least one protrusion of the base, the method comprising:

• aligning the imaging probe to the insertion site and at an insertion angle;
• using the angle indicator of the marking device to record the insertion angle associated with the angle markings of the angle scale;
• generating at least one mark on a skin of the patient using the at least one protrusion of the base of the marking device for marking the insertion site with respect to the base of the marking device;
• replacing the marking device with the needle guide;
• aligning the needle guide to the insertion site using the at least one opening of the needle guide and the at least one mark on the skin of the patient;
• and
• placing the needle in the insertion slot of the needle guide and at a guide angle marking corresponding to the insertion angle to guide the needle for needle insertion of the patient.
