Description
Technical field
The utility model is related to technical field of medical instruments, more particularly to a kind of microelectrode implant fixed on the retina
Device, be exactly specifically that a kind of surgical medical for fixing microelectrode implant on the retina is followed closely.
Background technology
Microelectrode implant is to aid in retina or the patient of other organs of vision generation lesion regains light
The vision prosthesis of bright and vision.The formation of normal vision is photosensory cell (cone cell and rod cell) on retina by light
Stimulation is converted into electric signal, after each confluent monolayer cells (horizontal cell, Beale's ganglion cells, nerve cell etc.) coding of retina, leads to
The continuity of the aixs cylinder of gangliocyte, i.e. optic nerve are crossed, nerve impulse is transferred to visual cortex.Therefore, current design is all
Microelectrode implant is implanted into each organ of pathways for vision, i.e., on retina optic nerve or visual cortex, electrode display directly will
The electric signal of encoded certain pulses form acts on these maincenters and peripheral nervous system, what analog vision was normally formed
Process.
In order to which microelectrode implant is implanted into retina, it is necessary to which microelectrode implant is fixed on into retina using spike
On, as shown in figure 1, China Patent Publication No. (CN105287100A), which discloses a kind of artificial retina microelectrode, fixes nail 10,
Including nail tip (there is nail tip head 1 and nail tip bottom 2), nail body 3, pad 4, spring buffer part 5, buffering fixed component 6, nail
Cap 7 and ailhead 8.The microelectrode fixes the implantation that nail is only used for macula retinae area, and due to macula retinae area and non-macula lutea
Area's thickness is different, thus defines the position used in retina.And the nail tip head 1 that the microelectrode fixes nail 10 is in four
Pyramid, when inserting or discharging retina, can be caused compared with macrolesion to retina；And at nail tip bottom 2 and the nail alternating of body 3
Stepped transition, the secondary injury of retina and microelectrode implant, Er Qierong can be caused by taking out when microelectrode fixes nail 10
Easily microelectrode implant is brought out；In addition, buffer unit 5 (spring) can not effectively limit nail tip insertion depth, it is unfavorable for doctor
Protect human users.
Therefore, those skilled in the art need badly research and development one kind can macula retinae area and non-macular area different-thickness position
Put and use, and can largely reduce retinal damage, avoid causing secondary injury to retina, easily operated operation
Medical nail.
Utility model content
In view of this, the technical problems to be solved in the utility model is that providing a kind of microelectrode of fixing on the retina plants
Enter the surgical medical nail of thing, solving can not be simultaneously in macular area and non-macular area during existing microelectrode fixes nail use
The position of different-thickness using, the relatively macrolesion that causes to patient's retina, easily cause secondary injury to retina the problem of.
In order to solve the above-mentioned technical problem, embodiment of the present utility model provides a kind of fixed micro- on the retina
