Sacral nerve stimulator program control instrumentTechnical field
The utility model relates to medical instruments field, in particular to a kind of sacral nerve stimulator program control instrument.
Background technology
For the patient of Spinal injury, often occur that detrusor urinae of bladder height opens the phenomenon of reflection and detrusor-sphincter muscle dyssynergia, cause uroschesis and renal impairment, mostly adopted pharmacological agent in the past, interrupted catheterization treatment and various operative treatment etc., but it is undesirable to there is effect, treatment cycle is long, the shortcomings such as complication is many, until the appearance of sacral nerve roots stimulator, it is the principle different with sphincter muscle biological characteristics based on detrusor, when adopting discontinuous pulses to stimulate, can owing to urinating occurs in the intravesical pressure of lasting rising between twice stimulation period, but this kind mode of urinating belongs to one and manually urinates pattern, stimulation parameter can not adjust by suitable carrying out, intravesical pressure is very high sometimes causes injury of the kidney, secondly before sacral nerve, root comprises the nerve fiber of some domination lower limb, the shake of lower limb can be there is when stimulating, the use of inconvenient patient, before using early stage sacral nerve during root stimulator program control instrument, sacral nerve sclera reinforcement art must be carried out, the height that can eliminate detrusor like this opens reflection, but do some problems that also can produce like this, such as: the row of losing just reflects and erect reflection, for some male patients, such cost is unacceptable.
Rijkhoff in 1991 etc. propose anode block technique, the conduction suppressing the big nerve of diameter can be selected by this technology, realizing minor diameter neural excited separately, this technology is applied in the process of root electricity irritation before sacral nerve by we, thus makes pattern physiological more of urinating. Before application anode block technique carries out electricity irritation sacral nerve, the method for root not only can be used for improvement and urinates, easy to use, also may improve row just in the future, make sacral nerve root stimulation technology be more suitable for the patient of incomplete injury of spinal cord, eliminate pain problem during incomplete injury of spinal cord patient's electricity irritation. In addition, do not need to carry out sacral nerve sclera reinforcement art will become possibility yet by this kind of method treatment spastic bladder.
