Description
Technical field
This utility model belongs to field of medical, is specifically related to a kind of intracranial skin electrode.
Background technology
Human brain is in normal physiological situation, and its cortical surface can produce faint bioelectrical signals and have certain regularity.When there is pathology pathological changes in brain, can there is significant change in its EEG signals discharge mode, and some pathological changes can make EEG signals discharge mode that special variation occurs, clinically, by observing the special variation of these discharge modes, can the disease of human brain be diagnosed and be treated.The most common case of at present carrying out Clinics and Practices by EEG (electrocardiogram) examination cerebral disorders is epileptics.So-called epileptics refers to because cerebral cortex paradoxical discharge makes patient and occurs the abnormal of ictal limbs tic or consciousness behavior, no matter whether patient's electroencephalogram shows effect all different from normal person and occur special variation, so EEG (electrocardiogram) examination has very important effect in clinical treatment epileptics.
Be able to clearly analyze electroencephalogram and need two conditions, the i.e. collection of EEG signals and analyzing and processing.At present the analyzing and processing of EEG signals is completed by electroencephalograph; And the collection of EEG signals has two kinds of methods at present, a kind of is the collection of scalp EEG signals, and the electrode that is about to some is placed in and on scalp, gathers EEG signals.The feature of this mode is noinvasive, easy and simple to handle.But because scalp is far away apart from cerebral cortex, intermediate structure is many, and signal attenuation is serious, and artifact is large, especially when patient outbreak, extremity are seriously twitched, so it is used to the general inspection of electroencephalogram; If be the accurate positioning operation of epilepsy surgery position, just need another kind of complicated intracranial eeg signal acquisition mode, use intracranial skin electrode.First this mode needs surgeon to carry out operation of opening cranium, then intracranial skin electrode is buried on cerebral cortex under cerebral dura mater, and electrode points and electrode cable by intracranial skin electrode gather EEG signals.Be characterized in the EEG signals that gathers almost undamped, without artifact, can accurately locate the scope of epileptic focus, so intracranial skin electrode is the requisite instrument of epileptics surgical operation.
Summary of the invention
The purpose of this utility model is to provide a kind of intracranial skin electrode, inaccurate to solve the signal that existing intracranial skin electrode gathers in operation process, human brain cortex is had to the problem of damage.
The purpose of this utility model is to realize like this, it comprises: electrode points, electrode cable, silica gel piece, numeral number sheet, silica gel sheath, plug, electrode points is embedded in silica gel piece, electrode points one side and the laminating of numeral number sheet, its laminating side is connected with electrode cable, electrode cable one end is connected with electrode points, and the other end is corresponding to be connected with plug, and its part of exposing silica gel piece is by the unified parcel of silica gel sheath.
It is that vertical sectional shape is like Chinese character " protruding " type or " mouth " type that concrete structure of the present utility model has electrode points; Horizontal plane is shaped as circle, ellipse, with handle shape disk or with medical stainless steel or the platinumiridio sheet of handle shape elliptical piece.
Concrete structure of the present utility model also has, every electrode cable corresponding with being connected an of electrode points, its junction point is embedded in silica gel piece; Electrode points and the numeral number sheet laminating back side of side and the plane of silica gel piece are that level is consistent, level protrusion or level recessed.
Distance between each electrode points of this utility model is 8-12mm.
Silica gel piece described in the utility model is divided into stripe shape, sheet type, T-shaped, L-type, O type, Q type by its horizontal plane shape.
Technique effect of the present utility model is, compared with prior art, the beneficial effect of this utility model intracranial skin electrode is:
1) vertical sectional shape of electrode points adopts like Chinese character " protruding " type, the design of " mouth " type, corticocerebral damage probability when this design operates in can reducing to perform the operation;
2) material of electrode points adopts platinumiridio, non-corrosive, conductivity be high, when patient does nuclear magnetic resonance check without artifact, bring great convenience to other inspections after surgical operation;
3) diameter of electrode cable is very thin and soft, and it is rear equally very soft that many electrode cables concentrate in together, and can not have influence on the pliability of silica gel piece, and this damage to cerebral tissue is very little.In addition the material of electrode cable has adopted platinumiridio equally, and non-corrosive, conductivity are high, and this makes the EEG signals that gathers almost undamped;
4) the preferred 10mm of the spacing between electrode points, when this spacing, collection EEG signals that can be comparatively sensitive, the diagnosis of raising epileptic focus.And according to the specific (special) requirements of operation, the spacing between all right self-defined electrode points;
5) deft design of intracranial skin electrode, rational in infrastructure, good looking appearance, simple and practical, not only reduced to operate the damage probability of intracranial skin electrode to cerebral tissue in operation, can also gather comparatively delicately EEG signals.
