Description
Technical field
The present invention relates to a kind of artificial lens injector of " All-in-One ", can by a variety of foldable artificial lens by≤
3.2mm otch is safely implanted in human eye.
Background technology
Cataract is not only the main reason for majority state blinding in the world, and is also the head of China's elderly population blinding
Want reason.China human mortality increase more than 1,000 ten thousand every year, to the year two thousand twenty population up to 1,500,000,000, wherein the ratio of 50 years old and above crowd
About 25.0%.Speculated with present development trend, the year two thousand twenty China cataract blindness number will be up to 506.25 ten thousand, and cataract blindness accumulates
To be increased than now by depositing number by nearly 1 times.
Regrettably, up to the present, still without a kind of active drug for being proved that cataract development can be reversed.
Operative treatment, especially cataract operation, which extract joint artificial lens (intraocular lens, IOL) implantation, is generally acknowledged in white
Barrier treats maximally effective means.Wherein, 1.8~3.2mm incision cataracts phacoemulsification joint back room folded form is manually brilliant
Body implantation is to treat the more satisfactory art formula of cataract.
Artificial lens is a kind of artificial lens that can be implanted into intraocular, has been extractd instead of postcataract muddy lenticular
Precision optics, on November 29th, 1949 are implanted into first by Britain Harold Ridley doctors.Artificial lens is typically by position
In the circular light department of the Chinese Academy of Sciences at center and button loop (support zone) composition on periphery.Because material is different, artificial lens be divided into optical section by
Rigid artificial lens made of the materials such as polymethyl methacrylate (PMMA), and optical section is by Silica hydrogel, hydrogel, propylene
Soft artificial intraocular lens made of the materials such as sour fat.Wherein, soft artificial intraocular lens, also often it is referred to as foldable artificial lens.Initially
Artificial lens be rigid artificial lens, need to (operative incision must be with optic diameter width substantially by more than 6mm otch
It is identical) implantation.With the development of cataract operation, otch also reduces increasingly, and the folded form adaptable therewith that has gradually been born
Artificial lens, intraocular can be implanted into by≤3mm otch under the auxiliary of implantation tweezer or implanting device, fold or curling after it is artificial
Crystal can Automatic-expanding after entering eyes.
Soft artificial intraocular lens method for implantation has two kinds：A kind of is traditional implantation tweezer implantation, and another kind is implanting device implantation,
The latter is current implantation soft artificial intraocular lens most efficient method, with having advantages below compared with the former：1. keep minimum to cut
Mouthful.Doctor can need not expand otch after ultrasonic emulsification for cataract, and soft artificial intraocular lens are implanted into intraocular by implanting device, made
Cornea postoperative astigmatism is preferably minimized.2. it is safe and reliable, do not damage artificial lens.Artificial lens is avoided using the implantation of implanting device method
The scratch and scratch of opticator, the cut of eyesight will not be had an impact.And folding line can be left on artificial lens surface by being implanted into tweezer
Or slight crack, it can affect one's power of vision.3. good controllability.Using implanting device, doctor can control artificial lens expansion speed and
The overall process of release, including suspend, invert, readjusting the position of crystal, avoid making to deploy as crystal blast because folding tweezer, can
Cause Poster capsulorhexis.4. reduce Postoperative inflammatory reaction.Foldable intraocular lens implantation and otch surrounding tissue can be made by implanting device implantation
And isolate outside eye, therefore reduce the risk for causing entophthamia by eye surrounding bacterial, also reduce postoperative uveal infusion reaction.
5. otch is safe, ne-leakage.It is more safer than implantation tweezer because implanting device need not expand otch when being implanted into crystal, it is postoperative to send out
The raw complication relevant with otch.Yang Xinghua et al. by cataract intraocular lens implanting forceps implantation with implanting device implantation after
The research of the parameters such as vision restoration, astigmatism and corneal endothelial cell counts, it is believed that two kinds of method for implantation are safe and reliable, wherein planting
Enter device implantation Postoperative visual acuity to recover faster, also relatively the implantation of implantation tweezer is light for the reaction of incision corneal edema, and astigmatism is small, and security is more
Height, it is worthy of popularization.
In order to reduce the infection risk after intraocular lens implantation, and mitigate the pain of patient, preferably planted from small otch
Enter artificial lens, so the trend of postcataract implant surgery is to be implanted into soft artificial crystalline substance by special implanting device at present
Body.With the arrival in micro-incision cataract operation epoch, intraocular lens injector head end diameter further reduces, at present can safety
It is 1.5mm that intraocular lens injector for clinic, which needs mini-incision, it is advantageous that operative incision is small, tissue damage is small, wound
Mouth healing is fast, postoperative astigmatism is small, inflammatory reaction is light, Postoperative visual acuity recovers fast, and can reduce the chance of intraocular infection.
Soft artificial intraocular lens implanting device includes non-prepackage type artificial lens type and prepackage type artificial lens type.1st, non-prepackage type
Artificial lens type implanting device is generally made up of importing head and injector two parts.Fig. 1 show existing clinical conventional a certain model
The construction of non-prepackage type artificial lens type implanting device, specific operating process are as follows：First, a small amount of viscoelastic agent is injected and imports head
Implant in and folded slot in, the center that foldable artificial lens is placed in folded slot makes crystal optics portion by tweezers
Divide in edge and crystal loop press-in folded slot (as Figure 1-1)；Then close up the folding wings on folded slot both sides, make crystal in folding
Overlapping state (as shown in Figure 1-2), the loop of crystal is checked whether behind correct position, be inserted in injector (such as Fig. 1-3,
Shown in 1-4)；Finally, implant opening bevel is downwardly into the pre- corneal incision opened and artificial lens is injected intraocular.There is scholar
Think that avoid artificial lens using the implanting device contacts with angle conjunctiva, reduces the risk of intraocular infection by research；Pass through
Implanting device implantation can artificial lens, avoid the damage in intraocular lens optic face；Operation facility, is easily mastered, Postoperative determination is good.2、
And prepackage type artificial lens type implanting device is generally integrally formed by importing head and injector.Certain existing clinical commonly used shown in Fig. 2
The construction of one model prepackage type artificial lens type implanting device, its feature be in advance by IOL load crystal storage in (such as Fig. 2-
Shown in 1), finished product opens packaging after factory, sterilization in operating room, by being directed at crystal storage and artificial lens injector
On arrow by crystal storage insert intraocular lens injector (as shown in Fig. 2-2), inject viscoelastic after discharging artificial lens
The head inclined-plane of intraocular lens injector band tip implant head is simultaneously downwardly into intraocular otch by agent, promotion push rod slowly, finally
Artificial lens is implanted into pouch.Whole operation process need to borrow other devices in operation like that not necessarily like non-prepackage type implanting device
IOL is loaded into implanting device by tool.Therefore, prepackage type can not only mitigate assistant's pressure, reduce operating time, improve operation effect
Rate, the chance that IOL is contacted in set-up procedure with extraneous bacterium is also further reduced, and then reduce postoperative infection risk.With
Cataract ultrasonic emulsification combines the extensive development of intraocular lens implantation, and present prepackage type IOL implanting devices are applied to clinic.Slowly
Dun Wen carries out intraocular lens implantation with non-prepackage type implanting device by application prepackage type and carries out clinical effectiveness comparison, it is believed that two kinds
Implanting device has preferable clinical effectiveness, but prepackage type IOL implanting devices are with more simple to operate, saving time, reduction infection etc.
Advantage, it is a kind of preferably IOL method for implantation.Whole implantation process artificial lens reduces postoperative sense not with organizing to contact outside eye
The generation of dye.
However, intraocular lens injector in the market also has corresponding deficiency, loading for such as non-prepackage type is cumbersome,
Need certain learning cycle, Rig up error can cause the fracture of artificial lens loop, crystal distortion upset, the rotation of crystal, after
Capsular rupture etc.；Though the implanting device of prepackage type have the advantages that it is simple and quick, save the time, reduce infection, because its design
Limitation, the artificial lens of some model or type can only be adapted to, then can not for the artificial lens of other models or type
Pre-installed (it is relevant with the characteristic difference of artificial lens, such as：It is the material of crystal, shape, infractive index, optical area diameter, total straight
Footpath, optics area thickness, marginal zone thickness, the thickness of loop and width, spring of arch etc.), use range limitation.Also because of prepackage type
Implanting device price costly, in vast remote districts, clinical practice is limited.In addition, Clinical practice is all types of foldable
Artificial lens and implanting device (including prepackage type and non-prepackage type), are substantially import, very expensive, many artificial lens are required
