The head end contact and the tail end electrode plate are respectively positioned at two ends of the silica gel main body and mutually connected through the conducting wire, the width of the silica gel main body is uniform, the head end contact is fixed on the silica gel main body, the tail end electrode plate is in the shape of a circular sheet, and the area of the tail end electrode plate is larger than that of the head end contact. Compared with the prior art, the leading electrode for the deep brain epileptic discharge, which is provided by the utility model, can effectively transmit high-voltage epileptic discharge at a cortex in a skull to the tail end electrode plate below the scalp outside the skull, so as to rapidly reduce the voltage level at the cortex and reduce or control epileptic attacks.
Description
[technical field]
This utility model relates to a kind of medical device for the treatment of the brain epileptic condition, relates in particular to a kind of leading electrode that the epilepsy discharge of brain deep regional epileptogenic focus can be directed to outside the cranium.
[background technology]
Epilepsy is a kind of chronic encephalopathy, is that the supersynchronous discharge owing to partial nerve unit in the brain forms, and is a kind of very common and multiple disease clinically, and sickness rate is about 0.9%.Epilepsy is that PDS arrives the high-amplitude epilepsy sample discharge of to a certain degree back generation thereupon because the interior excitatory postsynaptic potential of epileptogenic focus strengthens unusually.The neuron of epileptogenic focus adjacent domain produces synchronized epileptic discharge thereupon, and the paradoxical discharge of epileptogenic focus is more obviously strengthened, and causes clinical epilepsy, and the brain deep regional suffers from the patient of epileptogenic focus and accounts for 1/2 of epilepsy.
At present, treatment of epilepsy mainly is to pass through medicine, operative treatment, radiotherapy or electronic stimulation, no matter be any Therapeutic Method, its basic goal is to reduce the generation of epilepsy discharge or block its diffusion, to suppress to be the Therapeutic Method of basic theory, but do not still have patient's Drug therapy about 50% good or be impatient at side effects of pharmaceutical drugs, and radiocurable curative effect is undesirable, seldom use, operative treatment then expense is high and have a big risk, the probability that also has long-term complications, there is the clinical therapeutic efficacy about 40% not good approximately, so, making has 30% epilepsy not obtain the effective treatment at present nearly, thereby infringement of chronic function of nervous system and mental disorder occur.
May learn by Clinical detection, when the epilepsy discharge appears in the epileptic, epileptogenic focus in the cortex can produce high 10 times even more high-tension electrical activity than scalp place in cortex, can lead the zone that material is directed to the epilepsy discharge of cortex the relative low-voltage of intracranial this moment by height, thereby can reduce the intracranial voltage levvl, but lack this class device or device at present.
Given this, necessary a kind of brain deep epilepsy discharge leading electrode that provides solves the problems referred to above.
[utility model content]
The technical problem that this utility model solved is to provide a kind of brain deep epilepsy discharge leading electrode, it has overcome the deficiency of existing inhibition neuron dbd treatment, epileptic discharge is guided to outside the skull, avoided the epileptic discharge conduction and the clinical epilepsy of formation.
For solving the problems of the technologies described above, this utility model adopts following technical scheme: a kind of brain deep epilepsy discharge leading electrode, comprise strip silica gel main body, lay respectively at the head end contact and the end electrodes sheet at silica gel main body two ends and be embedded at the intravital lead of described silica gel master, described lead connects described head end contact and end electrodes sheet, described silica gel body width is even, described head end contact is fixed on the described silica gel main body, the rounded lamellar of described end electrodes sheet, its area is greater than the area of described head end contact.
Further, the surface that is projected on described silica gel cylinder of described head end contact.
Further, described end electrodes sheet and described silica gel body portion are from setting, and it is connected with the lead that stretches out from silica gel main body one end.
Further, the quantity of described head end contact is identical with described number of conductors, and described each lead connects a stature terminal contacts.
Further, described head end contact and described end electrodes sheet lay respectively at the inside and outside both sides of skull.
Further, the rectangular lamellar in described head end contact, its quantity is one or more, and arranges an end that is arranged at the silica gel main body along the longitudinally of silica gel main body.
Compared to prior art, epilepsy discharge leading electrode in brain described in the utility model deep can be effectively conducts to the high voltage epilepsy discharge at cortex place in the skull in the subcutaneous end electrodes sheet in skull the outside, thereby reduce the voltage levvl at cortex position rapidly, can reduce or the outbreak of Taking Control of Epilepsy.

Fig. 2 is the structural representation of this utility model brain deep epilepsy discharge leading electrode.
[specific embodiment]
See also illustrated in figures 1 and 2, be a kind of brain deep epilepsy discharge leading electrode 100 that this utility model provides, the lead 13 that it comprises silica gel main body 10, is located at the head end contact 11 of silica gel main body 10 1 ends, is positioned at the end electrodes sheet 12 of silica gel main body 10 other ends and connects described head end contact 11 and end electrodes sheet 12.
See also shown in Figure 1ly, described silica gel main body 10 is strip, and width evenly and be provided with vertical two ends.Described head end contact 11 rectangular lamellars, its quantity is two (also can be one or more), and arrange a vertical end that is arranged at silica gel main body 10, and the surface that is projected on described silica gel cylinder 10 of described head end contact 11 along the longitudinally of silica gel main body 10.Described end electrodes sheet 12 rounded lamellars, quantity is one, and be located at another vertical end of described silica gel main body 10, and the area of described end electrodes sheet 12 is greater than the area of described head end contact 11, make this end electrodes sheet 12 and described head end contact 11 lay respectively at vertical two ends of described strip silica gel main body 10 thus, and electrically connect by two leads 13 between the two, each lead 13 connects a stature terminal contacts 11, these two leads 13 link to each other with end electrodes sheet 12 respectively simultaneously, in addition, described lead 13 usefulness have an insulating barrier and are embedded in the described silica gel cylinder 10 and become one with silica gel main body 10, described head end contact 11 is fixed on the silica gel main body 10, and described end electrodes sheet 12 separates setting with described silica gel main body 10, it is connected with two leads 13 that stretch out from silica gel main body 10 1 ends, and described end electrodes sheet 12 surfaces are not with silica gel to keep layer, and it is used to place under the scalp in the no flesh layer subcutaneous tissue.
See also shown in Figure 2, sketch map when being applied in the brain 8 for brain described in the utility model deep epilepsy discharge leading electrode, when the patient produces the epilepsy discharge, the high voltage epilepsy discharge that epileptogenic focus place, brain deep discharge position 1 produces can be delivered in the end electrodes sheet 12 under the scalp 9 by the head end contact 11 in the epileptogenic focuses discharge positions 1 in the skull 7 and by the lead 13 in skull 7 holes, end electrodes sheet 12 under the described scalp 9 is again through the subcutaneous tissue diffusion, thereby reduce the voltage levvl at cortex position rapidly, avoid partial epilepsy discharge to form the clinical symptoms of epilepsy, thereby reach the purpose of minimizing or Taking Control of Epilepsy outbreak, overcome the deficiency of present epilepsy medicine and operative treatment.
