Technical field
The present invention relates to a kind of rotational positioning pin type electromyographic electrode and its external members, belong to medical instruments field.
Background technology
Electromyogram (electromyography) (English abbreviation EMG), applied electronics instrument record muscle is static or receives
The method that electrical activity and electrical stimulation during contracting check nerve, muscle excitement and conduction function.
The functional status of peripheral nerve, neuron, neuromuscular junction and muscle in itself can be determined by this inspection.
By measuring time limit, the wave amplitude of motor unit potential, whether there is spontaneous electrical activity in the case of quiet and muscle is big
The wave mode and wave amplitude that power is shunk can distinguish neurogenic urinary incontinence and Myopathic lesion, and the acute and chronic damage of diagnosis ventricornu is (such as
Anterior poliomyelitis, motor neuron disease), nerve root and peripheral neuropathy (such as electromyography can assist to determine
Position, degree, range and the prognosis of neurotrosis).In addition to the change of Neural entrapment venereal disease, neuritis, hereditary dysbolism nerve
Sick, various myonosus also have diagnostic value.In addition, electromyogram is additionally operable to track the extensive of disease in the therapeutic process of various diseases
Multiple process and curative effect.
Using computer technology, automatically analyzing for electromyogram can be made, such as parse electromyogram, single fiber electromyography and huge flesh
Electrograph etc. improves the positive rate of diagnosis.
Electromyography is mostly used pin electrode, however existing needle electrode is simple in structure, only an individual metal needle.
When carrying out checking with EMG method, it is sometimes desirable to multiple sites be carried out with checking with EMG method or the electro photoluminescence of priority, use traditional electricity
Pole can only be operated by doctor, and needle is applied in multiple sites.Not only positioning trouble, but also need to use more electrode needles in this way.

The position of stator connection is provided with through-hole, is passed therethrough for needle electrode head.
Further, rotational positioning pin type electromyographic electrode of the invention, can also have the feature that：Wherein, screw sleeve
Also as the driving lever of slip ring, slip ring rotation is driven.
The present invention also provides a kind of rotational positioning pin type electromyographic electrode external members, which is characterized in that including：At least two as weighed
Profit requires 1 or 2 rotational positioning pin type electromyographic electrode and cable buncher, and cable buncher collects two rotational positioning pin type myoelectricity electricity
The electrode wires that pole is stretched out.
Advantageous effect of the invention
The rotational positioning pin type electromyographic electrode and its external member of the present invention, be fixed on user due to the use of retainer ring four
Limb position, and multiple electrodes through-hole is provided on slip ring, the needle electrode head on slip ring can lead to from electrode through-hole
It crosses, so as to which after the checking with EMG method of a position, another test position can be repositioned, and make by slip ring
