Abstract
The utility model relates to a subdural detecting electrode which is composed of a pellosil carrier, electrodes fixed on the carrier in matrix arrangement, metal guide wires which are coated with an insulating layer and fixedly connected with the electrodes, plugs connected with the metal guide wires. The electrodes form a straw hat shape, wherein, the hat brims of the electrodes are inserted in the carrier, and hat top contacts are exposed out of the surface of the carrier. The electrodes are connected with an electro-encephalograph. Thus, biological signals from a human brain are received, and the source of an epilepsy focus is determined. The utility model has the advantages of small size, multiple detection points and high diagnosis accuracy rate.
Description
This utility model relates to a kind of department of cerebral surgery detecting electrode of the reception human brain bio signal that is connected with electroencephalograph, detecting electrode under particularly a kind of cerebral dura mater of definite epilepsy focus.
Before the operation of treatment epileptic patient, need accurately locate the focus source.The electrode volume that uses is big at present, and test point is few, low precision, and inconvenient operation can not be goed deep into detecting under the cerebral dura mater.
The purpose of this utility model is that the department of cerebral surgery that a kind of volume is little, diagnostic accuracy is high, can go deep into detecting under cerebral dura mater detecting electrode is provided.
Technical solution of the present utility model is as follows: design a kind of mesh electrode by the sub-dense arrangement of electrode, its composition comprises the pellosil carrier, be fixed on electrode that is matrix on the carrier and arranges, with the wire guide of the sub fixedly connected plating insulating barrier of electrode, be connected the plug of wire guide, electrode is the straw hat shape, its the brim of a hat is inlaid in the carrier, and its crown contact exposes carrier surface.
With reference to the accompanying drawings and in conjunction with the embodiments this utility model is described in detail.
Fig. 1 is this utility model overall structure sketch map.
Fig. 2 is Figure 1A-A cut-away view.
As depicted in figs. 1 and 2, this utility model is designed to a kind of mesh electrode by electrode 1 dense arrangement, its composition comprises pellosil carrier 2, be fixed on electrode 1 that is matrix row on the carrier and does, with the wire guide 3 of the sub fixedly connected plating insulating barrier of electrode, be connected the plug 4 of wire guide.Electrode 1 is the straw hat shape, and its brim of a hat is inlaid in the carrier 2, and its crown contact exposes carrier surface.Wire guide merging with 8 electrode of a row among the embodiment is connected with a plug 4.The about 7mm of the sub-the brim of a hat diameter of electrode, the about 4.5mm of crown diameter, thick about 0.1mm.
This utility model can once be encapsulated in thickness to 32 or 64 electrode only on the pellosil carrier about 1mm, and tolerance is less than 0.04mm, whole high conformity, smooth surface, softness can be covered in the cerebral tissue surface with no damage, carry out detecting under the cerebral dura mater, because being matrix, arranges electrode, make the electrode volume little, test point is many, the accuracy rate of diagnosis height, can reach 100%, easy and simple to handle, shorten detection time, reduce the patient suffering.
