Description
Technical field
The utility model belongs to implanted sclera electrode technology field, and hyposcleral gold can be embedded in for a long time by being related to one kind
Belong to electrode.
Background technique
1. the principle and type (glisten, is multifocal) of electroretinogram
After receiving light stimulation, nerve cell therein and non-neuronal cells generate a series of current potential and become retina
Change, referred to as view film potential.These potential changes can be recorded by being placed in cornea and its neighbouring electrode, record
The waveform variation arrived also becomes electroretinogram.Visual stimulus for inducing view film potential includes different strong and weak and colors
Flash of light and pictorial stimulus.According to the difference of stimulus type, view film potential is divided into flash of light view film potential, figure view film potential
And multifocal view film potential.
2. in order to which the variation of view film potential is recorded, it is necessary to which a recording electrode to be placed on cornea or eye
Near ball cornea.According to shape, recording electrode placement location and the difference for recording object, for recording the electricity of view film potential
Pole can be mainly divided into: Burian-Allen electrode, ERG-Jet electrode, DTL electrode, skin electrode, gold-foil electrode, Jin Huan electricity
Extremely etc..Burian-Allen electrode and ERG-Jet electrode are collectively referred to as cornea contact electrode again.
3. the measurement of human retina electrograph
For people, view film potential is mainly recorded using cornea contact electrode at present.In recording process, pass through
After eyeball surface anesthesia, ERG-Jet electrode or Burian-Allen electrode are placed in anterior corneal surface, then start subsequent note
Record process.In recording process, patient is needed to keep the instruction of awake and can be relatively good cooperation doctor.
4. the recording electrode of use mainly has golden ring electrode, Corneal Contact during the retina electrogram of animal
Electrode etc..Experimenter must anaesthetize animal before record starts, and then carry out the record of view film potential.
5. the vision system of monkey and people's height are similar to, eyeball structure is also roughly the same with human eye, no matter in physiological structure
It is all the experimental animal of closest people in genetic background.In the visual electrophsiology experimentation for being related to monkey, often take
Monkey is studied with the experimental facilities on people and clinical instrumentation.But since the eyeball of monkey and the eyeball of people dimensionally have one
Fixed difference tends not to the eyeball for agreeing with very much monkey with the electrode on people.When applying the electrode of people on monkey, will lead to
Record difficulty increases and causes the current potential of record unstable.Meanwhile in the recording process of the view film potential of monkey, monkey is all place
In narcosis, this, which also causes much to check, can not be successfully development.
6. Chinese patent publication discloses " a kind of novel cornea contact electrode " (application number 201120177016.1), the electricity
Pole is made of electrode wires, electrode wire terminal, electrode wires plug and pedestal.Electrode wires and Corneal Contact with conductive capability are used
In being guided out view film potential, connected by electrode wire terminal with electrode wires plug and pedestal with electrophysiology instrument.The invention
Electrode wires be it is disposable, avoid between different patients use with electrode wires caused by cross-infection.But for same
Patient, for, multiple checks whens, will replace different electrode wires, due to the difference of each electrode wires placement location, hold
Easily lead to the inconsistent of inspection result.Simultaneously because stimulation of the electrode wires to cornea, which is not used to awake move
On object.
Summary of the invention
The utility model will solve technical problem and be to provide one kind that hyposcleral implanted sclera electricity can be embedded in for a long time
Pole, the electrode can carry out multiple retina electrogram to same animal under waking state, and can guarantee record electricity
The stability of pole and tracer signal.
In order to solve the above-mentioned technical problem, the implanted sclera electrode of the utility model includes pellet electrode, electrode connection
Line, connecting terminal；The connection of one end of the pellet electrode and electrode connecting line.The other end and connecting terminal of electrode connecting line connect
It connects.
The pellet electrode uses Metal Flake electrode.
The pellet electrode is connect with electrode connecting line by cold-pressed joint, can guarantee its good conduction.
The pellet electrode is high-purity gold pellet electrode or platinum pellet electrode.
The electrode connecting line is the stainless steel wire for coating Teflon.
The connecting terminal is the copper connecting terminal of surface gold-plating.
The present invention is embedded in monkey by performing the operation using good biocompatibility, corrosion resistant metal as pellet electrode for a long time
Under the sclera of eyeball, for acquiring the signal of view film potential, led after collecting signal by electrode connecting line and connecting terminal
Out, and by visual electrophsiology instrument it is acquired record.
The invention belongs to visual electrophsiology field, it can be used for recording the view of Macaque of Macaca under awake or narcosis
Film potential carries out retina electrogram to monkey and carries out multiple retina electrogram to same animal, can guarantee
The stability of recording electrode and tracer signal.Electrode connecting line can be embedded in subcutaneously by the animal tail of the eye, be walked always
To the top of head, the crown is then fixed on by denture fixing device cement.When carrying out retina electrogram, by the connector of visual electrophsiology instrument
It is inserted into connecting terminal, sets the record that can start view film potential after reference electrode and ground electrode.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and detailed description.
Fig. 1 is the implanted sclera electrode schematic diagram of the utility model.
Fig. 2 is that pellet electrode is embedded in intrascleral schematic diagram.

As shown in Figure 1, the implanted sclera electrode of the utility model includes pellet electrode 1, electrode connecting line 3, terminals
Son 4；The pellet electrode 1 is connect with one end of electrode connecting line 3.The other end of electrode connecting line 3 is connect with connecting terminal 4.
Pellet electrode 1 is made using high-purity gold, platinum or gold-plated Kapton, and electrode connecting line 3 is using special rich
The stainless steel wire or silver wire of dragon insulation, connecting terminal 4 use copper and surface gold-plating connecting terminal.Pellet electrode 1
It is connect with electrode connecting line 3 by cold-pressed joint 2 or using spot welding mode.
In use, firstly, in the case where animal is in narcosis, pellet electrode 1 is embedded in animal by performing the operation
Under the sclera of eyeball, position as shown in Figure 2.Electrode connecting line 3 is embedded in subcutaneously by the animal tail of the eye, is walked always to head
Then the crown is fixed on by denture fixing device cement in top.When carrying out retina electrogram, the connector insertion of visual electrophsiology instrument is connect
Line terminals 4.Set the record that can start view film potential after reference electrode and ground electrode.
