Description
Technical field
The present invention relates to a kind of for sensing, the biological electric wave of record intracranial and the electrode of cranium electrical pulse to intracranial can be conducted, particularly a kind of Intracranical deep electrode.
Background technology
The brain of the mankind is continuing to send faint bioelectrical signals, and these bioelectrical signals are called as brain wave, is that of cerebral activity situation intuitively embodies.By monitoring and studying these faint signals of telecommunication, we can understand physiological status real-time in brain.Brain diseases or cerebral tissue pathological changes can cause abnormal cerebral tissue electric discharge, this meeting of special epileptics causes the disease of the strong paradoxical discharge of brain, doctor can be helped to determine kind and the pathogenetic position of disease of disease by the monitor cerebral signal of telecommunication, for determining that therapeutic scheme provides valuable information.
People use the disc-shaped metal electric limit with wire to be attached on scalp the earliest, and EEG signals brain being diffused to this point of scalp is collected and carried out the research of brain wave figure after being passed to signal amplifying apparatus process, and this electrode is called scalp electrode.This monitoring method is simple to operation, but due to the stop of skull and scalp, very disperse and faint when eeg signal is passed to scalp, and usually with many interfering signals, be therefore difficult to accurately locate the position that in brain, the specific brain regions signal of telecommunication sends.
There is the intracranial skin electrode directly electrode points being placed in human brain surface subsequently.This electrode, owing to directly contacting brain cortex surface, has accurate positioning signal feature clearly to the EEG signals monitoring of cerebral cortex part.By the Cortical ECoG active signal collected, can for next step excision Epileptic focus of doctor, avoid brain function district partition information be the most accurately provided.This eeg monitoring method has become the goldstandard determining brain paradoxical discharge position in epileptics diagnosis, is widely used in the diagnosis of epileptics and neurosurgery.This intracranial skin electrode also provides strong instrument to the research worker being engaged in the aspect such as neuromodulation, brain-computer interface simultaneously.
But intracranial skin electrode still has limitation, for need to gather cerebral cortex return the EEG signals at position with the ditch that hypencephalon deep part or intracranial skin electrode are difficult to monitor time, when region of particularly showing effect is positioned at cerebral deep, cortical electrode is just difficult to be competent at.
Intracranical deep electrode is different from intracranial skin electrode, and it not only can detect the electricity physiological signal of Cerebral cortex, can be deep into brain deep simultaneously, obtains the electricity physiological signal in the inner variant region of brain.In the diagnosis of epileptics, Intracranical deep electrode may have the monitoring of the deep regions of substantial connection can obtain better effect with epilepsy for several.These regions comprise Hippocampus routine in temporal lobe, corpus amygdaloideum, entorhinal cortex and parahippocampal gyrus etc.Depth electrode can record the information of brain ditch depths and isocortex, even can also carry out three-dimensional labelling to epileptogenic focus and discharge process.Depth electrode not only can be used on the epilepsy phase and stage of attack interocclusal record brain bioelectrical activity, can also to implant some place brain area carry out functional indicia, this point has vital meaning when Epileptic focus adjoins brain function region.
Intracranical deep electrode not only can receive EEG signals, can also be discarded to brain region of interest within from instrument Received signal strength.When Intracranical deep electrode is connected to electric stimulating instrument, electricity irritation or neural tuning can be carried out in art by regulating specific electric pulse.When Intracranical deep electrode is connected to radiofrequency generator or Electrocoagulation equipment, coagulation radiofrequency ablation or radio-frequency ablation procedure can be implemented in electrode points.
Intracranical deep electrode has the intrusive mood cranium brain of wound to detect apparatus as a kind of, and its application risk can not be ignored.Common Intracranical deep electrode uses complication to be: cerebrospinal fluid seepage, craniocerebral injury, implant site are hemorrhage, infection etc.Often there will be because the actual implantation position of electrode departs from preoperative path planning simultaneously, cause electrode wide target spot and affect monitoring effect and even cause the situation of operative failure to occur.
The main cause of cerebrospinal fluid seepage is that intracranial pressure is greater than external atmosphere pressure, makes cerebrospinal fluid be forced out outside cranium along Intracranical deep electrode tubular media inner chamber, brings larger infection risk simultaneously.Craniocerebral injury causes primarily of two kinds of reasons: 1. electrode points scratches neighbouring tissue, blood capillary (causing petechia among a small circle); 2. the electrode with certain degree of hardness is originally experienced cerebral tissue motion and surrounding brain tissues damage that the counteracting force that produces causes.Simultaneously when using Intracranical deep electrode to implement coagulation radiofrequency ablation or radio-frequency ablation procedure, needing monitoring temperature target area being had to enforcement, controlling and ensureing surgical effect and patient safety.Cranium brain has wound to detect often can with higher complication risk; doctor is in order to ensure the life security of patient; generally can prepare a set of intracranial pressure monitoring equipment specially separately, to grasp patient's intracranial pressure situation of change in real time, can the very first time obtain message when situation is abnormal and react.But intracranial pressure monitoring equipment requires that insertion apparatus is to intracranial separately, adds more wound and misery to patient.
