Description
Technical field
This utility model belongs to bionical field of medical device, is specifically related to a kind of acquired blindness patient visual and recovers lost eyesight intelligence object wearing device.
Background technology
Eyes be the human knowledge external world important by way of and window, be organ-tissue the most complicated in human visual path, the human knowledge world 70% information above comes from the visual performance of eyes.Owing to a variety of causes causes ocular vision functional disability, the patient even lost, according to World Health Organization (WHO) 2002 annual report, world vision crippled 1.4 hundred million, it is wherein blind patient more than 45,000,000 people, and annual is also expanding with the speed of newly-increased 7,000,000 blind patients.Misery inconvenient and huge greatly is there is in blind patient on life, study and work.
The pathways for vision of human body is: light → cornea → pupil → crystalline lens → vitreous body → retina (cone cell, rod cell → bipolar cell, horizontal cell, amacrine cell → ganglionic cell) → optic nerve → occipital cortex and other cortical areas → formation sensation, human brain further identifies, analyzes, judges and remember the complex behaviors such as contrast, finally forms the visual concepts such as the shape of object, color, orientation and speed in the brain.
On pathways for vision, retina, optic nerve, visual cortex equivalent damage all can cause blind, but, the reason of most acquired blindness patient's blindings is retinal illness, i.e. retinitis pigmentosa and two kinds of topmost pathological changes of age-related macular degeneration.Although, the retina of patient is downright bad, but the optic nerve being connected with retina still keeps suitable activity.
Medical expert early than nineteen twenty-four when the district's electricity irritation of patient's optic cortex, it has been found that patient creates visual hallucination, it is believed that suitable electricity irritation is the sensation that patient can be helped to produce image.Hereafter, electrode is implanted to blind patient and volunteers the amphiblestroid corresponding site of experimenter by research worker, and by stimulating the retina cell of remaining, last part has recovered the vision of patient, thus, further demonstrate that the mode of recovering lost eyesight of electrical stimulation is feasible.
At present, the vision prosthesis based on electrical stimulation substantially can be divided into three kinds: visual cortex vision prosthesis, optic tract vision prosthesis and retinal visual prosthese.Visual cortex vision prosthesis and optic tract vision prosthesis, owing to technical difficulty is big, X factor is more, and difficult in development process, particularly visual cortex directly stimulates, it is possible to brings out local apoplexy or epilepsy, brings health risk to patient.Therefore, its technical prospect can not show a candle to retinal visual prosthese.
The operation principle of retinal visual prosthese is to utilize the prosthese implanted that external view signal is converted into the signal of telecommunication, directly stimulates the retinal neuronal cell of internal layer, to replace photoreceptor cell，photosensory cell, makes patient recover a degree of vision.Implantation position according to stimulating electrode chip is different, and retinal visual prosthese is divided into epiretinal prosthesis prosthese (stimulating electrode and chip are positioned at ophthalmic retina top layer), outer stratotype artificial retina prosthese (stimulating electrode and chip are between view neuroepithelium and retinal pigment epithelium).
Owing to the chip implanted in retinal visual prosthese and stimulating electrode need to provide electric energy to work.At present, electric energy supply mode has two kinds: implant battery and wireless energy supply.Implantation battery working time is short, it is necessary to periodically battery is taken out and changed by operation, easily brings secondary injury and misery to patient.Wireless energy supply is to utilize electromagnetic induction principle to carry out energy transmission, and by firing frequency mode, the electromagnetically induced coil system being made up of external transmitting coil and internal receiving coil produces faradism to provide electric energy；Wireless energy supply is feasible in theory, it solves a technological approaches difficult problem for energy transmission, but the difficulty of practical operation is very big: 1. owing to coil space size is limited, the energy of supply is extremely limited.2. a large amount of heat production of meeting in charging process of chip and coil, can bring damage to surrounding tissue, easily cause patient uncomfortable.3. the biocompatibility of chip and coil method and tissue, long-term stability problem not easily solve.
Retinal visual prosthese technology, owing to stimulating current intensity and the frequency of chip have mixed up and solidification before implantation, can not change after implantation, for single standard, it is difficult to adapt to the demand of the individual variation of hundreds and thousands of blind blind person.
Additionally, there is also the difficult problems such as the electrode of microelectrode array is few to quantity, effect of stimulation is poor.
