Needle electrode with metal male buckle

Technical Field

The utility model belongs to the technical field of medical instrument equipment, especially, relate to a take needle electrode of metal pin thread.

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. In addition, 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 utility model because the stimulated limbs are repeatedly moved to a large extent during the 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.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings.

The first embodiment is as follows: according to the attached drawings of the specification, a needle 11 electrode with a metal male buckle 12 comprises an acupuncture needle 11 which is not wound with a metal wire at the tail end or is provided with other additional handle devices and is made of stainless steel, and the needle head of the acupuncture needle 11 is inserted into the subcutaneous space of the limb and is used as an electrode for transmitting stimulation signals. Referring to the conventional needle 11, the needle 11 has a length of 1/2, 1, 1.5, 2, 2.5 and 3 inches, and a diameter of 0.2, 0.25, 0.30 and 0.35 mm. The hand-held end of the acupuncture needle 11 is provided with a metal male buckle 12, the cross section of the metal male buckle 12 is in an omega shape, a circular groove matched with the acupuncture needle 11 is arranged in the metal male buckle 12, and a gap left after the acupuncture needle 11 is inserted into the circular groove is filled with soldering tin 13 to realize the conductive connection of the acupuncture needle and the acupuncture needle.
