Description

The peripheral nerve semi-implantation type electric stimulation controller

Technical field

This utility model belongs to biomedical engineering field, particularly relates to a kind of intelligent peripheral nerve semi-implantation type electric stimulation controller of exquisiteness.

Background technology

Along with the fast development of China's industrial economy and communications, the high-energy trauma patient obviously increases, and the peripheral nerve injury very high based on this class disability rate of brachial plexus nerve become common clinical and frequently-occurring disease.To the regeneration behind the peripheral nerve injury, although it is neural to adopt meticulous microsurgical technique to repair at present, use medicine, hormone and nerve growth factor to promote its regeneration, neuranagenesis speed is still undesirable.Electricity irritation is as a kind of physiotherapy, be to utilize the promotion that is used for of electric current to damage peripheral nerve regeneration and prevent that flesh from withering, its effect extensively is subjected to certainly at academia, successively confirms that with a large amount of zooperies electricity irritation can promote obviously that the peripheral nerve regeneration that damages speeds up from Wilson, Pomeranz, Fakhouri, Politis etc. in 1976.Nineteen eighty-three Raji confirms that electric-impulse stimulation can promote Mus sciatic nerve functional rehabilitation, and can increase the diameter of nerve injury section and section regeneration aixs cylinder far away, and accelerator nerve damage section far away Wallerian degeneration improves neuranagenesis speed.Domestic many scholars have also carried out electricity irritation separately and have promoted perineural experiment of damage or clinical research.A large amount of experimentatioies confirms that electricity irritation has the effect that promotes peripheral nerve regeneration.Though electricity irritation at present promotes the damage peripheral nerve regeneration and prevents that the mechanism that flesh withers from not illustrating as yet that its effect is sure, has been widely used in orthopaedics, hands surgery, neurosurgery and rehabilitation section etc.

The stimulation mode of electricity irritation mainly contains two kinds at present: transcutaneous electrostimulation and implantation type electric stimulation.Both respectively have its pluses and minuses.The advantage of transcutaneous electrostimulation is to have avoided the loaded down with trivial details operation of body embedded set electrode and needed operation once more to take out, and the wound that causes of needle electrode, characteristics such as has conveniently, no pain and indication are extensive.But it has following shortcoming: (1) specific aim is not strong, and weak effect mainly is because stimulus intensity is limited, because higher stimulus intensity patient can not feel well, and the possibility of skin scald is arranged; (2) twice stimulus intervals are oversize, because percutaneous stimulation all is to carry out in hospital mostly; (3) patient's compliance is poor.Compare to transcutaneous electrostimulation, the advantage of implant electrode is can round-the-clock lasting stimulation, and because its direct stimulated muscle or nerve, its stimulus intensity can be than big many of transcutaneous electrostimulation, also can avoid inconvenience that transcutaneous electrostimulation brings, sense of discomfort and can not pinpoint defective (Osterman).Its shortcoming is the loaded down with trivial details operation of body embedded set electrode and needs operation once more to take out, and electrode itself damages the mechanics that nerve may cause.

Summary of the invention

Technical problem to be solved

Technical problem to be solved in the utility model provides a kind of intelligent peripheral nerve semi-implantation type electric stimulation controller of exquisiteness, accurately produce electrical stimulation signal by the artificial adjustment microprocessor, the output stimulus parameter also can be preserved stimulus information, adopt the liquid crystal display mode, clearly know and monitor selected intensity of electric stimulus, frequency, pulsewidth, waveform and intermittent time.
