Description

Disposable low-frequency electrical stimulation treatment needle

Technical Field

The utility model relates to the technical field of medical instrument science, in particular to a treatment needle for low-frequency electrical stimulation, and specifically relates to a disposable treatment needle for low-frequency electrical stimulation.

Background

Low frequency electrical stimulation therapy is a commonly used treatment for clinical rehabilitation physical therapy, and the continuous change of the frequency of low frequency current causes excitation of neuromuscular tissue, thereby causing muscle contraction to improve local blood circulation, which can increase local nutrition, help recovery of atrophied muscle, and further help recovery of muscle function. After the neuromuscular stimulation is performed by the factors such as the waveform, the intensity, the lasting time and the like of the low-frequency currents of different types, the reactions generated by the neuromuscular are different, so that the effect of treating different types of diseases is achieved. Aiming at different clinical treatment purposes, a plurality of low-frequency electrical stimulation treatment instruments named for the treatment purposes are on the market at present, electrode plates used for the treatment are various and different, but the manufacturing structure and the principle of the electrode plates are basically consistent.

Nowadays, the low-frequency electrical stimulation therapy electrode plates applied in the market have the following two types: (1) most of the electrode plates are made of insulating rubber, conductive rubber and plug connectors in a compounding manner and can be repeatedly used; (2) the self-adhesive electrode plate is composed of non-woven fabric, conductive cloth, conductive fiber, conductive gel, PVC protective film, wire and connector, and is manufactured in different types and forms for different treatment parts.

However, the applicant finds that the prior art has at least the following problems in implementing the embodiments of the prior art:

(1) the electrode sheet (self-adhesive electrode sheet or rubber composite electrode sheet) is fixed on local skin of a pre-treatment part, and conducts current into the skin to play a role. Except invasive acupuncture electrodes clinically used for myoelectricity examination, the electrodes clinically used for treatment at present are non-invasive skin surface electrodes, the accuracy of treatment selection parts is not high, and the accuracy is not high, particularly when the electrodes are applied to treatment of peripheral nerve injury, the stimulation range covers all tissues (skin, subcutaneous tissues, muscles and the like) under the electrodes, and the aim of specifically and accurately stimulating muscle bundles innervated by injured nerves cannot be achieved;

(2) in the treatment, the muscle bundle innervated by the damaged nerve and the muscle bundles innervated by the peripheral normal nerves are electrically stimulated, and after the treatment, even if the damaged nerve and the muscle bundles innervated by the damaged nerve gradually recover the function, the muscle strength and the function are still inconsistent with the muscle fiber thickness, the muscle strength and the function of the peripheral normal nerves and the muscle bundles innervated by the peripheral normal nerves to a certain extent and within a certain period of time. When the surface electrode plate is used for treating injured nerves and muscle bundles innervated by the injured nerves, the surface electrode plate is beneficial to the functional recovery of the injured nerves and the muscle bundles innervated by the injured nerves, and peripheral normal nerves and the muscle bundles innervated by the injured nerves are also subjected to electric stimulation, so that the functions of the injured nerves and the muscle bundles innervated by the injured nerves are further strengthened, and the surface electrode plate is always stronger than the injured nerves and the muscle bundles innervated by the injured nerves, and cannot achieve functional consistency in a short time.

Therefore, in order to perform precise treatment on the damaged nerve and the dominant muscle bundle thereof, research and design of a disposable low-frequency electrical stimulation treatment needle electrode specially used for treating peripheral nerve injury is urgent.
