Изобретение относитс  к медицине и может быть применено в клиническо нейротравматологии. Известен способ диагностики Повреждени  нерва путем введени  в два участка нерва микроэлектродов, раздражени  одного участка нерва импульсньлм электрическим током и регистрации на другом участке потенциалов действи  1. Однако известный способ не позво л ет определить степень повреждени  в ходе нейрохирургической операции. Целью и-зобретени   вл етс  определение степени повреждени  в ходе нейрохирургической операции. Эта цель достигаетс  тем, что микроэлектроды ввод т с помощью . стериотаксического устройства поочередно в каждый пучок нерва выше и ниже места повреждени  его, регистрируют потенциалы действи  каждого из пучков и по количеству повр дённых пучков определ ют степень п овреждени  нерва. Способ осуществл ют следующим образом. Нейрохирург надевает телескопические очки или проводит исследование под операционным микроскопом. Под нерв дистальнее и проксимальнее его поврежденного участка подвод т глубинную лампу дл  вы влени  нерванеизмененной части по .обе c-io роны от места повреждени  которые видны в проход щем свете глубинной лампы и не видны на уровне повреждени  нерва, ориентируют пучки по сосудам нерва. С помощью стереотаксического устройства ввод т раздражающий и регистрирующий мультимикроэлектрсмды по обе стороны от места поврёжде ни  на уровне наибольших изменений нерва по проекции пучка и через эпиневрий и периневрий на одну и ту же глубину до по влени  потенциалов действи  амплитудой О,,вы вл ют наличие проводимости пучка, и электроды извлекают.. ... СтереотакЬическим устройством измен ют положение мультимикроэлектродов поочередно по проекции других пучков и по окружности нерва. При наличии вызванных потенциалов действи  циклы .повтор ют над другими пучками. Вы вл ют исчезновение проводшлости наружного пучка нерва по отсутствию вызванных потенциалов и ввод т стереотаксическим устройством вглубь нерва одновременно раздража1ощи  и регистрирующий мультимик роэлектроды на рассто ние несколько большее диаметра наружного пучка к более глубоко расположенному пучку по поперечнику нерва и производ т исследование. Такие циклы повтор ют до вызывани  потенциалов, и мультими роэлектроды извлекают, или проход т поперечник нерва полностью при отсутствии потенциалов на всех уровн х исследовани . По количеству поврежденных пучков определ ют степень повреждени  нерва. . Предлагаемый способ позвол ет определить степень повреждени  в ходе нейрохирургической операции. Формула изобретени  Способ дигностики повреждени  путем введени  в два участ90 , ка нерва микроэлектродов, раздражег1и  одного участка нерва электрическим -:-током и регистрации на другом участке потенциалов действи , о тличающийс  тем, что, с целью определени  степени повреждени  в ходе нейрохирургической операции, микроэлектроды ввод т с помощью стереотаксического устройства поочередно в каждый пучок нерва выше и ниже места повреждени  его, регистрируют пЬтенциалы действи  каждого из пучков и по количеству поврежденных . пучков определ ют степень повреждени  нерва. Источники информации, прин тые во внимание при экспертизе 1. Нейрохирурги  . Ред. В. А. Шустина . 1971, т. 4, с.,159-163.This invention relates to medicine and can be applied in clinical neurotraumatology. A known method for diagnosing nerve damage is by introducing microelectrodes into two nerve sites, stimulating one nerve site with a pulsed electrical current and registering action potential 1 at another site. However, the known method does not allow determining the extent of damage during neurosurgical operation. The purpose of the invention is to determine the extent of damage during neurosurgical operation. This goal is achieved by introducing microelectrodes with. The sterotactic device alternately into each nerve bundle above and below its injury, record the action potentials of each of the bundles, and determine the degree of nerve damage by the number of damaged bundles. The method is carried out as follows. The neurosurgeon puts on telescopic glasses or conducts research under an operating microscope. Under the nerve distal and proximal to its damaged area, a depth lamp is supplied to detect the nerve-unchanged part along the c-io axis from the injury site, which are visible in the transmitted light of the depth lamp, and are not visible at the level of nerve damage, orient the bundles along the nerve vessels. With the help of a stereotactic device, annoying and recording micromicroelectrics on both sides of the injury site are introduced at the level of the greatest nerve changes in the beam projection and through epineurium and perineurium at the same depth until the action potentials are amplitude O, the presence of conductivity is revealed the beam, and the electrodes are extracted ... ... with a stereo-tactical device they change the position of the multi-microelectrodes alternately along the projection of other beams and along the nerve circumference. In the presence of evoked action potentials, the cycles repeat over other beams. The disappearance of the external nerve bundle by the absence of evoked potentials is revealed, and a stereotactic device is inserted into the nerve at the same time as an irritant and recording multi-microelectrodes a little larger than the external beam diameter to the more deeply located beam along the nerve diameter and produce research. Such cycles are repeated until the potentials are called up, and the multimylectrodes are extracted, or the nerve diameter passes completely in the absence of potentials at all levels of investigation. The degree of nerve damage is determined by the number of damaged beams. . The proposed method allows the degree of damage to be determined during a neurosurgical operation. The invention of the method of damage diagnosis by introducing microelectrodes into one of the two sites90, a canal nerve, electrical stimulation of one nerve site -: - current and recording action potentials on another site that are different in that, in order to determine the extent of damage during a neurosurgical operation, microelectrodes enter Using a stereotaxic device, alternately in each bundle of the nerve above and below the site of damage, record the potential of each of the bundles and by the number of injured. beams determine the degree of nerve damage.
