The special electrode for the therapeutic instrument providing percutaneous electric stimulation for the surrounding nerves is characterized in that the center of the insulator is provided with a round raised simulating point. The stimulating point is connected with an electric stimulator by an interface converter through a conducting wire and an end of the special electrode for the therapeutic instrument providing percutaneous electric stimulation for the surrounding nerves. Compared with the prior art, the special electrode for the therapeutic instrument providing percutaneous electric stimulation for the surrounding nerves has advantages that 1) the contact of percutaneous electric stimulation with the services is noninvasive; 2) the electric stimulating point is good in directivity and an effective therapeutic effect can be realized by adopting comparatively low simulation strength; 3) the risk of burning skin at a contact point is low; 4) the special electrode for the therapeutic instrument providing percutaneous electric stimulation for the surrounding nerves is easy to install and dismount; 5) the stimulation technique is non-invasive and the special electrode for the therapeutic instrument providing percutaneous electric stimulation for the surrounding nerves can be implanted and taken out without surgery; 6) the special electrode for the therapeutic instrument providing percutaneous electric stimulation for the surrounding nerves is simple to operate and wide in indication range; 7) the therapeutic instrument and the special electrode for the therapeutic instrument providing percutaneous electric stimulation for the surrounding nerves are comparatively low in cost and easy for popularization.
Description
Technical field
This utility model relates to the technical field of transcutaneous electrostimulation peripheral nerve therapeutic instrument electrode special, and is especially a kind of among a small circle neuroactive transcutaneous electrostimulation peripheral nerve therapeutic instrument electrode special accurately.
Background technology
Peripheral nerve paralysis is common clinical and frequently-occurring disease, and common have brachial plexus paralysis, ulnar nerve paralysis, musculospiral paralyses, median nerve paralysis, tibial nerve paralysis, a paralysis of common peroneal nerve etc.At present along with medical science applied progress, though it is neural to adopt meticulous microsurgical technique to repair, use means such as hormone, nerve growth factor, neural stem cells transplantation that the nerve of damage is recovered to some extent, but electricity irritation is as a kind of physiotherapy, its by electric current be used for promote perineural Regeneration and Repair and prevent that amyotrophy is by a large amount of clinical and experiment confirms, and be widely used in the rehabilitation of nerve, muscle equivalent damage, irreplaceable effect is still arranged.
It is clinical common diseases that the peripheral nerve embedding is pressed, because the complexity of the pathology damage mechanism after the neural embedding pressure, clinical function is recovered also to be not quite similar.The embedding of application transcutaneous electrostimulation treatment peripheral nerve is pressed and is levied after the operation decompression, can promote the early rehabilitation of function of nervous system.Case 28 examples are pressed in 1 material and method 1.1 this group of material peripheral nerve embeddings, are that undergraduate course is accepted for medical treatment over 5 years.Include standard in; Through the invalid and neural loosening therapy of row operation of expectant treatment.Exclusion standard: neural anastomosis and the case of transplant repairing loosen again case and non-operative treatment.
Electricity irritation electrode commonly used has semi-implantation type electrode, implanted electrode and surface electrode.Semi-implantation type is that electrode is implanted, and that controller and stimulator are placed on is external, is easy to realize the accurate control to muscle; Implanted electrode is that stimulator and electrode are all implanted, controller with radio frequency in the body the stimulator energy supply and control.Semi-implantation type and implanted electrode all can directly excite nerve, and the electric current of use is little, all need operation to implant and take out electrode but shortcoming is for both, electrode itself may cause the mechanics infringement to nerve, therefore its specification requirement specific surface electrode height, is difficult to carry out clinically.Surface electrode is to be affixed on the skin surface that shallow place is shown in the nerve trunk conduct most, and the electric current of electrode output acts on nerve through skin.Compare with other electrodes, surface electrode has following advantage: 1, install easily and remove; 2, stimulating technology is atraumatic, need not operation and implants and take out electrode; 3, simple to operate, indication is extensive, promotes easily; 4, instrument and electrode are relatively cheap.Therefore surface electrode is most widely used in electricity irritation.
But present electrode has following shortcoming: 1, the entire electrode sheet is conductive material, and is big with the epidermis contact area, and specific aim is not strong; 2, need higher stimulus intensity just can work, and higher intensity may make the patient not feel well, the risk of skin scald is arranged simultaneously.Therefore, how can be neural through the shallow table of epidermis point-like contact, and the non-invasive therapy that uses less stimulus intensity just can reach effective therapeutic effect is the focus of present rehabilitation medicine worker's growing interest.
Shanghai Metallurgy Inst., Chinese Academy of Sciences; Materials Physics and Chemistry (specialty) thesis for the doctorate 2000 annual purposes: the influence of the neural electrophysiology of research transcutaneous electrostimulation after to Rats'Sciatic Nerve Injury, inquire into the effectiveness that electricity irritation promotes that function of peripheral nerves is recovered.Method: the row microsurgery nerve anastomosis skin electricity irritation of passing through of going forward side by side behind the cross-section rat sciatic nerve of performing the operation, adopt electrophysiological method to observe electricity irritation to the influence of peripheral nerve regeneration, and compare with matched group.Result: electricity irritation group impaired sciatic incubation period (0.58±0。33ms) than matched group (2.27±0。88ms) shorten the difference significance.Conclusion: transcutaneous electrostimulation may have the effect that promotes that impaired peripheral nerve regeneration and conduction function recover.
Summary of the invention
This utility model provides a kind of transcutaneous electrostimulation peripheral nerve therapeutic instrument electrode special for solving the problem of above-mentioned existence.
The technical solution of the utility model is achieved in that a kind of transcutaneous electrostimulation peripheral nerve therapeutic instrument electrode special, include insulator, it is characterized in that: described insulator center is provided with the stimulation point of a circular protrusions, and stimulation point is connected with electrostimulator by interface convertor with an end of electrode by seal wire;
Described stimulation point is the copper conductor stimulation point, and diameter is 5mm;
Described electrostimulator is the low-frequency pulse machine.
Beneficial effect
The advantage that this utility model contrast prior art has is: 1. percutaneous contacts neural non-invasive; 2. electricity irritation point is with strong points, and coloured silk is little with the risk that less stimulus intensity just can reach effective therapeutic effect 3. contact point skin scalds; 4. install easily and remove; 5. stimulating technology is atraumatic, need not operation and implants and take out electrode; 6. simple to operate, indication is extensive; 7. instrument and electrode are relatively cheap, promote easily.
