Description
Technical field
The utility model relates to field of medical appliances, especially a kind of arc-shaped electrode for encephalic implantation.
Background technique
Deep brain stimulation is the effective ways for treating dyskinetic disorder, while being also the strong of research brain function
Tool.As popularization of the Deep brain stimulation on clinical treatment and lesions located in deep brain joint electrophysiological recording are in brain
Gradually go deep into terms of functional study, while to the multiple and different nerve nucleus implant electrodes of encephalic, enabling single piece of electrode of implantation
Enough while multiple target nerve cores group is contacted, has important application value.Multicore group's joint lesions located in deep brain has monokaryon
Effect not available for group's lesions located in deep brain.
However, since current lesions located in deep brain electrode is linear type, also using current deep brain stimulation electrode
Do not accomplish arbitrarily by single piece of electrode while to be implanted into multiple encephalic targets.Due to passing through the straight line of two targets simultaneously
Have and only one, therefore two intracranial targets are implanted to simultaneously with one piece of linear type deep brain stimulation electrode and are only applicable to seldom
The target spot of amount combines, such as nucleus accumbens septi+anterior limb of internal capsule (patent: deep brain stimulation electrode and device, Authorization Notice No.: CN
204092843 U).Linear type deep brain stimulation electrode more optionally can not select target spot to combine, once two targets
Distance is farther out or the extended line of the line of two targets is not suitable as lesions located in deep brain electrode implantation channel, this method
It may be difficult to apply.However, there is presently no the arcs for being intended to simultaneously stimulate multiple nerve nucleus with single piece of electrode
Lesions located in deep brain electrode.
Summary of the invention
The utility model proposes a kind of arc-shaped electrodes for encephalic implantation, can introduce electrode to encephalic with arching trajectory,
It is able to achieve the joint electro photoluminescence to optional two encephalic nerve nucleus, and different nerve nucleus can be applied different
Stimulation parameter.
The utility model uses following technical scheme.
A kind of arc-shaped electrode for encephalic implantation, the arc-shaped electrode includes the electrode shealth of conducting filament and arc；It is described
Conducting filament is placed in electrode shealth；Electro photoluminescence output contact, the electro photoluminescence output contact and conduction are equipped at the electrode shealth wall
Silk connects to export the electric signal of conducting filament.
It is equipped with M electro photoluminescence at the beginning of the arc-shaped electrode and inputs contact, is equipped with M at the extending part of arc-shaped electrode

Arcuately the arc of electrode body moves towards arrangement for the electro photoluminescence input contact and electro photoluminescence output contact.
Electro photoluminescence inputs contact, the width of electro photoluminescence output contact is 0.5-2mm.
The electro photoluminescence output contact walks to be upwardly formed more than one stimulation group in electrode；Adjacent electricity in each stimulation group
Stimulate the spacing of output contact identical.
The electro photoluminescence input contact and electro photoluminescence output contact are the ring-shaped contact of surrounding electric poles sheath side wall setting；Institute
The cross section for stating arc-shaped electrode is round or oval.
The conducting filament quantity is not less than one.
The conducting filament is with the soft silk of metal material moulding, and the electrode shealth is formed with soft toughness material.
The radian at each position and of same size on the arc-shaped electrode extending direction.
The utility model overcomes piece lesions located in deep brain electrode of the prior art only for an intracranial target, or only
Electro photoluminescence can be carried out to two target spots of approach on an independent beeline channel, can be realized to optional two encephalics
The joint electro photoluminescence of nerve nucleus, and can different nerve nucleus be applied with different stimulation parameters, improve lesions located in deep brain
Efficacy and saferry of the art in the treatment such as dyskinetic disorder, mental disorder.
In the utility model, the electrode shealth is formed with soft toughness material；This design can make electrode be easily implantable encephalic,
And electrode is not likely to produce screen resilience, to protect encephalic tissue.
Detailed description of the invention
With reference to the accompanying drawings and detailed description to the further details of explanation of the utility model:
Attached drawing 1 is the schematic diagram of the utility model；
Attached drawing 2 is the cut-away illustration of electrode shealth；
In figure: 1- electro photoluminescence inputs contact；2- electrode shealth；3- electro photoluminescence output contact；4- stimulation group；5- conducting filament.
