Description
Technical field
The present invention relates to a kind of implantation device, particularly a kind of artificial cochlea's cranked electrode implantation device.
Background technology
Artificial cochlea is a kind of electronic installation, by external speech processor, sound is converted to the signal of telecommunication of certain coding form, is recovered by the direct excited acoustic nerve of electrode system implanted or is rebuild the auditory function of deaf person.In recent years, along with the development of electronic technology, computer technology, phonology, electrophysiology, materialogy, otomicrosurgery, artificial cochlea enters clinical practice from experimentation.The present whole world is deaf to complete deafness conventional method as treatment severe using artificial cochlea.Artificial cochlea electrode used in the world divides straight electrode and the large class of cranked electrode two at present.Straight electrode can not accomplish that nearly modiolus stimulates, and may damage cochlea during implantation.Cranked electrode is implanted inconvenient, if be not cannot implant in cochlea electrode Zhang Zhi before implantation, the pre-buried support inner core when electrode array joins mostly is adopted beyond institute, by a straight support inner core cranked electrode Zhang Zhi, during operation, insertion limit in limit is extracted out and is supported inner core, electrode inserts and supports steel core and extracts out synchronous, electrode inserts too fast easy damage cochlea or bending supports steel core, electrode inserted slow, supporting-core is extracted out and too fastly is easily made electrode tip hook back to be stuck in cochlea cannot replant in cochlea, owing to cannot turn back in electrode again after supporting-core extraction, electrode cannot insert cochlea again, can only more go to implant by transducer set implant, operation is caused to be interrupted, operating time is long, Cochlea is increased the weight of, in art, visual effect is also bad simultaneously, does not see the concrete situation of insertion, easily scratches electrode colloidal silica and wire electrode insulating barrier, make electric pole short circuit, owing to there being supporting-core, electrod-array is thick, is difficult to make very thin shape, affects implantation depth, also do not have good implanting instrument and method that cranked electrode is implanted in safely in cochlea at present.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of structure simple, easy to use and facilitate cranked electrode implant cochlea, artificial cochlea's cranked electrode implantation device of the damage to cochlea that improves implantation efficiency, alleviate patient's misery, decreases.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of artificial cochlea's cranked electrode implantation device, comprise and implant handle and be arranged on the conduit implanted on handle, described conduit is provided with fluting, and one end of conduit is provided with locating open choma, and the other end of conduit is provided with reinforced cut-out ring group; Conduit is plugged with push rod, and push rod is provided with limited block.
Further, the afterbody of described push rod is provided with push rod handle, and push rod is kink the coupling part of handspike.
Further, the head of described push rod handle is provided with protection ball.
Further, described protection ball is spherical form.
Further, described locating aperture ring is arranged on the outer peripheral face of conduit.
Further, described reinforced cut-out ring group is arranged on the outer peripheral face of conduit.
Further, described reinforced cut-out ring group the second reinforced cut-out ring of comprising the first reinforced cut-out ring and being arranged in parallel with the first reinforced cut-out ring.
Further, described implantation handle is provided with some fixing holes.
Further, the surface of described implantation handle is provided with anti-slip veins.
Adopt artificial cochlea's cranked electrode implantation device of technique scheme, because described conduit is provided with fluting, one end of conduit is provided with locating open choma, and the other end of conduit is provided with reinforced cut-out ring group; Conduit is plugged with push rod, and push rod is provided with limited block, so can implant cranked electrode easily and safely to cochlea by this implantation device.Afterbody due to described push rod is provided with push rod handle, and push rod is kink the coupling part of handspike, so can be better to the feel effect of operative doctor in the process implanting cranked electrode by arranging kink, and convenient situation of observing implantation cranked electrode.Because the head of described push rod handle is provided with protection ball, described protection ball is spherical form, so anti-cutting hands.Because described locating aperture ring is arranged on the outer peripheral face of conduit, described reinforced cut-out ring group is arranged on the outer peripheral face of conduit, the second reinforced cut-out ring that described reinforced cut-out ring group comprises the first reinforced cut-out ring and is arranged in parallel with the first reinforced cut-out ring, so can prevent deformation of guide tube by arranging reinforced cut-out ring group.Because described implantation handle is provided with some fixing holes, so can be connected by external stability support by some fixing holes.Because the surface of described implantation handle is provided with anti-slip veins, so have antiskid function.
