Its advantage shows: the utility model discloses it has one deck silica gel film to serve to cover at the electrode tip, utilizes the surface tension of cerebrospinal fluid, makes the electrode head end adsorb at encephalic corresponding site, can not lead to the fact the damage to the local organization, electrode line middle part be helical structure, can hang operation at the bottom of the laterocranium strut the ware on, convenient fixed, do and play the effect that cushions the tractive, avoid causing the aversion of encephalic electrode because of the tractive of electrode line afterbody, rise to the inside shielding net that is equipped with of the circuit of tail end, the transmission loss of reducible signal, shielding external disturbance at electrode line middle part.
Description
Technical field
This utility model relates to a kind of recording electrode, specifically, is a kind of intracranial noinvasive recording electrode device.
Background technology
Bioelectric signal recording electrode is the measuring device for gathering human biological signal, the recording electrode being applicable to intracranial has ping-pong ball electrode, circular electrode and needle electrode, although wherein ping-pong ball electrode, circular electrode noinvasive, but not easily fixing or needs are fixed by gel, needle electrode is fixedly easier to, but can cause damage to local organization.
The electrogram of intracranial is near field potential, and signal is good, but one of clinical difficult point is perplexed in the placement of localizing electrode.According to reliable fixing mode, easily damage is caused, as clamp, acupuncture etc. to the tender tissue of bearing; If pursuit noinvasive, then easily there is displacement, cause recording unsuccessfully in simple electrodes.Meanwhile, skull base surgery belongs to microsurgery, and operating theater instruments is many, easily causes outside electrode wires by tractive.And electrode wires is by after tractive, gently then electrode head end comes off, heavy then cause avulsion etc. to the tissue of electrode head end.Therefore, fixing of electrode head, and prevention afterbody tractive is the key point of this relevant apparatus research and development.
About fixing simple, noinvasive, anti-tractive, the recording electrode that other electrical equipment disturb wire can be reduced again simultaneously, yet there are no report.
Summary of the invention
The purpose of this utility model is, provides a kind of intracranial noinvasive recording electrode device.
For achieving the above object, the technical scheme that this utility model is taked is:
A kind of intracranial noinvasive recording electrode device, described recording electrode device comprises electrode and electrode wires, described electrode is positioned at the front end of electrode wires, described surrounding them is provided with silica gel thin film, described electrode wires front portion is single strand wire, and the outside of single strand wire is provided with insulating barrier, is helical structure in the middle part of electrode wires, line-internal to tail end in the middle part of electrode wires is provided with gauze screen, and electric wire wraps by described gauze screen.
Described electrode head end is spherical or netted.
Described gauze screen is brass wire shielding net.
This utility model advantage is:
1. this utility model is coated with one deck silica gel thin film on electrode head end, utilizes the surface tension of cerebrospinal fluid, makes electrode head end be adsorbed on intracranial corresponding site, can not cause damage to local organization.
2. be helical structure in the middle part of electrode wires, can hang on the dilator of lateral skull base, the convenient fixing effect simultaneously can playing buffering tractive, avoids the tractive because of electrode wires afterbody to cause the displacement of intracranial electrode.
3. electrode wires middle is provided with gauze screen to the line-internal of tail end, can reduce the loss of signal, shielding external interference.
4. the head end of electrode is spherical or netted, is applicable to different parts.
