(54) ЭЛЕКТРОД(54) ELECTRODE

1one

Изобретение относитс к медицин17 а именно к нейрохирургии, и может быть использовано при электрофизиологических исследовани х поврежденного нерва во врем операции.The invention relates to neurosurgery, 17 and can be used for electrophysiological studies of the damaged nerve during surgery.

Известен электрод, содержащий контактную головку, выполненную из двух полуколец, и руко тку, выполненную в виде двух соединенных между собой стержней, образующих пинцет, внутри стержней расположены проводники 1 .A known electrode containing a contact head made of two half-rings, and a handle made in the form of two interconnected rods forming tweezers, conductors 1 are located inside the rods.

Однако изв естный электрод не позвол ет исследовать отдельные пучки обнаженного нерва во врем операции. Целью изобретени вл етс обеспечение возможности исследовани отдельных пучков обнаженного нерва во врем операции.However, an observable electrode does not allow for the examination of individual bundles of the exposed nerve during surgery. The aim of the invention is to enable the examination of individual bundles of the exposed nerve during an operation.

Поставленна цель достигаетс тем, что контактна головка имеет не менее трех токопровод щих элементов , установленных с рабочей стороны контактной головки, два из которых расположены Диаметра/зьно противоположно друг другу, причем контактна головка выполнена из изол ционного мате зиала,The goal is achieved by the fact that the contact head has at least three current-conducting elements installed on the working side of the contact head, two of which are located diametrically opposite to each other, and the contact head is made of insulating material,

На фиг. Д изображен предлагаемый электрод (пунктиром показан электродFIG. D shows the proposed electrode (the dotted line shows the electrode

при разжатии двух половин контактирующей головки); на фиг. 2 разрез А-А фиг. 1; на фиг. 3 - схема использовани предлагаемого устройства; на фиг. 4 - взаимосв зь.пучков нерва и электродов.when unclamping the two halves of the contacting head); in fig. 2, section A-A of FIG. one; in fig. 3 is a diagram of the use of the proposed device; in fig. 4 - interconnection of nerves and electrodes.

Электрод содержит изолирующую руко тку 1, им.еющую два полых стержн 2, 3 соединенных в виде пинцета, The electrode contains an insulating handle 1, named after two hollow rods 2, 3 connected in the form of tweezers,

0 свободные концы стержней 2, 3 переход т в полукольца 4, 5 контактирующей головки 6, которые своими торцовыми част ми прижаты друг к другу за счет пружин щих свойств 2, 3. 0, the free ends of the rods 2, 3 are transferred into semirings 4, 5 of the contacting head 6, which are pressed against each other by their spring-loaded properties 2, 3.

5 Внутри полых стержней 2, 3 и контактирующей головки 6 проход т проводники 7, подсоединенные к электропровод щим элементам 8. Последние расположены по внутренней поверхности 5 Inside the hollow rods 2, 3 and the contacting head 6, conductors 7 are connected to the electrically conductive elements 8. The latter are located along the inner surface

0 полуколец 4, 5 так, что два электрода наход тс в диаметрально противоположныхточках , а третий - в любом месте.0 half-rings 4, 5 so that the two electrodes are in diametrically opposite points, and the third is in any place.

Электрод используетс следующим The electrode is used as follows.

5 образом.5 way.

Полукольца 4, 5 контактирующей головки 6 разжимают при помощи ру- ко тки 1 до образовани зазора меж ,ду торцами полуколец 4, 5. Далее Half rings 4, 5 of the contacting head 6 are unclenched with the help of handle 1 until a gap is formed between the ends of the half-rings 4, 5. Further

Claims

0 pass the investigated nerve in the open3. tia formed by semicircles 4, 5 and clamped it (the fixation of the nerve occurs automatically with the removal of efforts that were applied to unseat the semirings. At the same time, the nerve bundles are in contact with the electrical wire Schkmk elements 8. .. The study is conducted either with one electrode or two, located on the nerve, on both sides of the site of damage, in the case of using two devices, the elements .8 are connected to the electric pulse 9 through the switch 10 by means of conductors 7. An electric current pulse passes through the circuit: Sator 9, switch 10, wire NICKY 7 of the right device, electrodes 8, a certain bundle of nerve, then along the analogous circuit of the left device and then on the indicator 11. The biocurrent pulse passes through the circuit: a certain bundle of nerve, element 8 of the right or left device, etc. .K 7, the switch 10 and further on the indicator 11. Then the devices are rotated through a certain angle and the above operation is repeated until all the beams lying on the surface of the nerve are examined. Claims of Invention Electrode comprising a contact head made of two half-rings and a handle made of two interconnected rods forming tweezers, conductors are located inside the rods, characterized in that, in order to enable the examination of individual beams of the exposed nerve during operations, the contact head has at least three conductive elements installed on the working side of the contact head, two of which are diametrically opposed; each other, the contact head being made of an insulating material.
