Technical Field

The invention belongs to the technical field of medical equipment, and particularly relates to a needle electrode with a metal male buckle.

Background

Various medical electronic devices are widely applied in the field of diagnosis and treatment at present, and especially play an increasingly important role in the aspect of nerve/meridian function regulation and control, especially in the motor function reconstruction of paralyzed limbs. Among these functional regulation applications, needle electrodes with minimally invasive characteristics are the most preferred potential electrodes. However, in all current electric acupuncture apparatus for meridian and collateral control, a conventional acupuncture needle is directly used as a needle electrode, and an electric signal is applied to the acupuncture needle through a metal clip connected to a cable. The disadvantages are that: 1) the depth of acupuncture is difficult to control, 2) the clip on the acupuncture needle brings the needle body exposed outside to shake back and forth due to the weight of the clip itself and the connecting line and the vibration of muscles during stimulation, which not only brings discomfort to the patient, but also affects the treatment effect. Furthermore, the method of clamping the conventional acupuncture needle with the metal clip cannot be applied even to the motor function reconstruction treatment of the paralyzed limbs by the electromyographic-neural bridge type electro-acupuncture limb movement instrument of our invention because the stimulated limbs are repeatedly moved to a large extent during such treatment. Therefore, the scheme provides the following needle electrode with the omega-shaped metal male buckle, which is more suitable for the minimally invasive functional electrical stimulation of the human nerves/channels. The electrode is not only suitable for using the electromyography-nerve bridge type electro-acupuncture limb movement instrument to carry out the reconstruction treatment of the movement function of the paralyzed limb, but also suitable for using the existing electro-acupuncture instrument to carry out the regulation and control of the meridian function.

Disclosure of Invention

In view of the above situation, in order to overcome the defects of the prior art, the invention provides a needle electrode with a metal male buckle, which solves the problem that the conventional acupuncture needle in the prior art is difficult to control the insertion depth of a clip clamped on the acupuncture needle, and the clip can shake back and forth to influence or even interrupt the treatment due to the vibration of muscles.

The technical scheme is that the needle electrode with the metal male buckle comprises an acupuncture needle without winding a metal wire or other additional handle devices at the tail end, wherein the metal male buckle is arranged at the tail end of the acupuncture needle, the cross section of the metal male buckle is in an omega shape, and a circular groove with the diameter slightly larger than the tail end of the acupuncture needle is arranged on the metal male buckle.

Preferably, the acupuncture needle is made of stainless steel.

Preferably, the tail end of the acupuncture needle is placed in a circular groove of the metal male buckle and then is welded and fixed with the conductor by adopting soldering tin as a conductor, so that a structure suitable for muscular nerve electrical stimulation with strong robustness is formed.

Preferably, a disc-shaped double-sided adhesive-coated insulating film is adhered to one side of the metal male buckle close to the acupuncture needle, so as to form a structure for conventional muscle nerve electro-acupuncture stimulation.

Preferably, the portion of the surface of the acupuncture needle outside the circular groove of the metal male snap is coated with an insulating film, and then only the metal of the needle point is exposed, so as to form a structure for inducing punctual accurate stimulation of meridian/nerve signals.

Preferably, the metal male buckle is externally sleeved and buckled with a metal female buckle electrically connected with the metal male buckle, the surface of the metal female buckle is covered with an outer cover plastic with a set color, and the metal female buckle is connected with the myoelectricity-nerve bridge type electroacupuncture limb movement instrument through a cable.

Preferably, a concave groove with a slope structure is arranged at the position, close to the brim-shaped edge of the metal female buckle, of the plastic of the outer cover, the depth of the concave groove is 2-3mm, and a structure which is convenient for taking out the acupuncture needle with the metal male buckle from the metal female buckle after the acupuncture needle is used is formed.

The invention has the advantages that the metal male buckle is arranged at the tail part of the acupuncture needle, the depth of the acupuncture needle inserted into the limb is accurately controlled by combining the lengths of the existing acupuncture needles with different specifications on the market, and the metal female buckle sleeved on the metal male buckle ensures that the myoelectric signals can be stably detected and transmitted even if muscles vibrate or the limb moves greatly in the treatment process without influencing the treatment effect;

the acupuncture needle adopts the cable with the metal female buckle to be connected with the prior various electric acupuncture instruments and the micro-electronic myoelectricity bridge type limb movement instrument for realizing the reconstruction of the motion function of the paralyzed limb, and has the advantages of simple operation, accurate acupuncture depth, safety, stability and reliability in the electrical stimulation process.
