Abstract
The invention discloses a manufacturing method for auditory brainstem stimulation electrode, comprising steps of performing stamping and cleaning on a contact electrode on the surface, cleaning a puncture electrode, connecting an electrode wire, the surface contact electrode and the puncture electrode through welding, arranging the electrode wires, aligning ends of the contact electrode and the puncture electrode on the welding surface, cutting off the residual electrode wires on the other ends, injecting prepared silica gel into a die by a half depth, performing one-time curing, when the degree of curing achieves 80%, arranging the surface contact electrodes and the puncture electrodes in a staggering manner to put into the die, after the silica gel is fully cured and the surface contact electrodes and the puncture electrodes are fixed with the cured silica gel, injecting the prepared silica gel into the die until the half of the contact electrode is immersed in the silica gel, performing secondary heating curing and trimming the residual silica gel after the silica gel is drawn out of the die. The invention can reliably finish the fixation of the surface contact electrodes and the puncture electrodes, enables the brainstem stimulation to have a good effect, simplifies the procedure and improves the efficiency.
Description
Technical field
The invention belongs to medical instruments field, particularly the manufacture method of a kind of tin of property brain stem stimulating electrode.
Background technology
For severe or pole severe deafness, cochlear implant is unique effective device helping deaf residual patient to recover audition recognized in the world, but, a lot of disease is as 2 type neurofibromatosiss, bad, the bilateral acoustic nerve traumatic injury of tympanum gasification, auditory nerve hypoplasia or defect, the diseases such as cochlea hypoplasia or senile neurological deafness, cause the hearing loss of more than acoustic nerve, we are deaf patient after being called snail.For these patients, its audition cannot be recovered by artificial cochlea.
Listening property of electronics brain stem implants (AuditoryBrainstemImplant, ABI) technology is as the state-of-the-art technology of auditory nerve repair and reconstruction, be to think after treatment severe snail that deaf patient is most advanced at present, be also unique effective technology, make patient again obtain audition by walking around acoustic nerve and directly stimulating its brain stem cochlear nuclei, and not yet have the manufacture method of disclosed ripe listening property brain stem stimulating electrode at present.
Summary of the invention
The technical problem to be solved in the present invention is to provide and a kind ofly can completes the fixing of surface contact electrode and penetrating electrodes more reliably, and make brain stem effect of stimulation better, step simplifies, the listening property brain stem stimulating electrode manufacture method of raising the efficiency.
To achieve these goals, technical scheme of the present invention is as follows: the manufacture method of a kind of tin of property brain stem stimulating electrode, comprises the following steps:
Effects on surface contact electrode carries out punching press and cleaning, cleans penetrating electrodes, by wire electrode and surface contact electrode and penetrating electrodes by being weldingly connected;
Arrange wire electrode, alignd one end of face of weld contact electrode and penetrating electrodes, unnecessary wire electrode is cut by the other end;
The silica gel modulated is injected the mould half degree of depth, carries out one-step solidification, when state of cure 80%, surface contact electrode and penetrating electrodes are staggered, put into mould;
Treat that silica gel solidifies completely, after the silica gel of surface contact electrode and penetrating electrodes and solidification is fixing, then the silica gel that will modulate injects mould, did not have the degree of depth of half, and carried out secondary heating solidification to surface contact electrode;
From mould after molding, prune unnecessary silica gel.
Alternatively, after the unnecessary silica gel of described pruning, under stereomicroscope, check that whether brain stem stimulating electrode is complete, whether wire electrode damages, and whether surface contact electrode evenly exposes.
Alternatively, after the unnecessary silica gel of described pruning, the surface contact electrode of brain stem stimulating electrode and the electrode impedance of penetrating electrodes are measured, stimulating current strength range and stimulation precision are measured.
Alternatively, the described one-step solidification time is 2min.
Alternatively, the temperature of described secondary heating solidification is 140-160 DEG C, and hardening time is 60-70min.
Beneficial effect of the present invention is: the present invention can complete the fixing of surface contact electrode and penetrating electrodes more reliably, and make brain stem effect of stimulation better, method step simplifies, and raise the efficiency, technological requirement is uncomplicated, and cost is low.
