PREFERRED EMBODIMENT OF THE INVENTION

[0034] In light of the mentioned figures, and according to the numbering taken on them, can be seen in them an example of non-limiting realization of the recommended protected needle with high ultrasound visibility for performing ultrasound-guided percutaneous electrolysis or neuromodulation techniques, which includes the parts and elements indicated and described in detail below.

[0035] Thus, as can be seen in FIG. 1, according to the prior art, the needles (1′) to perform ultrasound-guided percutaneous electrolysis or neuromodulation techniques are dry puncture or acupuncture needles formed by a conductive metallic grip (2), coupled to the handle that connects it to the device that generates the electric current to be applied (element not shown) and a body (3), also conductive metallic, in the form of a fully cylindrical, thin and long rod, of variable length among 30, 40, 50 60, 75 and 100 mm, with the blunt tip (4), both made of stainless steel.

[0036] And, as can be seen in FIGS. 2 and 3, the protected needle with high ultrasound visibility (1) of the invention, also consisting of a dry puncture or acupuncture needle formed by a conductive metallic grip (2), coupled to the handle that connects it to the device that generates the electric current to be applied and a body (3), also conductive metallic, in the form of a long thin rod, of variable length among 30, 40, 50, 60, 75 and 100 mm, and with the blunt tip (4), which is distinguished in that at least the body (3), and preferably also the grip (2), are made of a material that maximizes its density and/or a shape that minimizes refraction ultrasound to give it high ultrasound visibility, and in that, in addition, said body (3) is provided with a biocompatible electrically insulating protection layer (5) that covers practically its entire length, except for a working segment (6) of variable length (l) before the blunt tip (4).

[0037] Preferably, said material that maximizes its density to increase its visibility in the ultrasound machine, at least in the body (3) is galvanized steel, and preferably the shape it presents to minimize ultrasound refraction, at least at the working end (6) is a non-cylindrical shape of the rod that forms said body (3) of the needle, being, for example, spiral, flat, quadrangular, triangular or other that, in any case, provides a greater bounce surface and less refraction than a surface cylindrical to the incidence of the ultrasound waves, whereby its visibility in it is increased, being able to comprise both characteristics at the same time, that is, to be made of galvanized steel and present, at least in the working segment (6), said non-cylindrical shape.

[0038] In any case, preferably, the biocompatible electrically insulating protection layer (5) is constituted by a Teflon coating. And, preferably said working segment (6) that does not cover the protection layer (5) has a length (l) between 0.1 mm and 10 mm.

[0039] Optionally, the needle (1) of the invention allows an insertion into the skin with less pain. Extremely useful in dry puncture and percutaneous electrolysis. In the latter case, once the target tissue is reached with the help of the ultrasound machine, it is attached to the handle. The guide tube is still useful, so that it pierces the skin better and that the patient feels less pain. In our case, we will also use it (they are needles that bend easily and, in some cases, do not pierce the skin well).

[0040] Having sufficiently described the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make a more extensive explanation thereof in order that any expert in this area will understand its scope and the advantages that can be derived from it, making known that, within reason it could be put into practice in other embodiments differing in detail from that indicated by way of example, and with which it will also achieve the protection that is sought provided that its fundamental principle is not altered, changed or modified.
