The intraocular lens push injector comprises a connecting rod, a lens push pin and a floating device, wherein the connecting rod is pushed to push a lens push pin in the push-injecting process, the lens push pin is used for pushing an intraocular lens in the pushing process under the pushing effect of the connecting rod, the floating device is used for connecting the lens push pin with the connecting rod and used for enabling the lens push pin to vertically float within a certain range.
Description
Technical field
The present invention relates generally to intraocular lens injector.More specifically, the present invention relates to crystal to push pin float type artificial intraocular lenses injector.
Background technology
Artificial intraocular lenses is a kind of artificial lens implanting ophthalmic, and it is applied in ophthalmologic operation.Such as, in cataract operation, be used for the technology of the mineral crystal replaced in the human eye becoming muddiness because of cataract conditions by implantable artificial crystal and extensively implemented.The form of artificial intraocular lenses, is normally made up of the button loop of the circular light department of the Chinese Academy of Sciences and periphery that are positioned at center.Because the material of processing artificial intraocular lenses is different, the rigid artificial intraocular lenses that artificial intraocular lenses is divided into optic to be formed by hard materials such as PMMA, and the soft artificial intraocular lens of the flexible material formation such as optic is by silicone elastomer, hydrogel, soft acrylic's fat.The artificial intraocular lenses be made up of soft material, is also often referred to as collapsible artificial intraocular lenses.
When using rigid artificial intraocular lenses, the operative incision of the implantable artificial crystal that cornea is outputed must be substantially identical with optic diameter width.And soft artificial intraocular lens can folding or curling reduce its area after implant ophthalmic by a less otch (general 2-3 millimeter).This folding or curling after soft artificial intraocular lens enter eyes after can Automatic-expanding.
In order to reduce the infection risk after implant surgery, and alleviate the misery of patient, preferably from minimal incision * implantable artificial crystal, so the trend of current implant surgery implants soft artificial intraocular lens.In order to soft artificial intraocular lens is implanted ophthalmic, need to use special intraocular lens injector, this intraocular lens injector has inner chamber design and elongated tubular passageway structural design that artificial intraocular lenses is folded.By the intraocular lens injector using this special, soft artificial intraocular lens (collapsible artificial intraocular lenses) can be folded and be implanted in human eye by the minimal incision * being less than 3 millimeters.And, use this intraocular lens injector to implant, effectively can reduce operative incision, reduce operation link, and easy to use, save preparation and the operating time of ophthalmologic operation, injected rear artificial intraocular lenses in pouch, be easy to abundant expansion.
Soft artificial intraocular lens implantation device comprises non-pre-iol cartridge type and pre-iol cartridge type.Non-pre-iol cartridge type implantation device is made up of importing head and injector two parts usually, as shown in Figure 1.Fig. 2 schematically shows the injector of the intraocular lens injector of prior art and imports the assembling of head.As shown in Figure 2, importing head is installed in injector.The main operation of non-pre-iol cartridge implantation device implantable artificial crystal is used to generally include: in importing head, inject viscoelastic agent, tweezers are used artificial intraocular lenses to be taken out from packing box, artificial intraocular lenses is put into importing head to clamp, then the importing head of clamping artificial intraocular lenses is inserted in the draw-in groove of injector front end, the push rod promoting injector makes crystal push pin and artificial intraocular lenses is shifted onto the front end of importing head, wherein crystal is through importing the interior tract of head by auto-folder, finally inserts the corneal incision opened in advance and artificial intraocular lenses is injected ophthalmic.
At present, the importing head of conventional on market intraocular lens injector all adopts polypropylene for medical article, through EO sterilizing; The employing titanium alloy that injector has, some employing rustless steels, all provide non-sterile product, need through autoclave sterilization before using.
There is inclined design at the rear portion importing head, and as shown in Figures 3 and 4, wherein Fig. 3 schematically shows the structure of the intraocular lens injector of prior art.The intraocular lens injector of Fig. 3 comprises crystal and pushes pin, overlap pipe carrier and import head, and the inner chamber road wherein importing head has inclined design.Fig. 4 is another sectional view of the structure of the intraocular lens injector schematically showing prior art.As shown in the figure, pushing pin when entering tract in importing head at crystal, being cushioned by inclined design and transitting in interior tract.Crystal is pushed pin and is close to the bottom of importing head in the process, and the own stress deformation and crystal is pushed pin, exists downward pressure.As shown in Figure 5, when not with any object contact, crystal is pushed pin and substantially should be in level, i.e. position shown in dotted lines in Figure 5, push pin due to crystal and import tract in head and contact and interact, crystal is pushed pin and to be lifted in traveling process forward, and crystal is pushed pin and pushed that to import actual position after head be the position in Fig. 5 shown in solid line.Push pin due to crystal and deformation occurs thus the pressure produced against importing tract in head, and produce frictional force thus.And crystal is pushed pin as metal material, the frictional force that in head, tract exists is larger with importing.
In the injector structure of prior art, it is one or fixing dead that crystal is pushed pin with pushing portion (push rod), thereby produces series of problems of the prior art.Such as, the optical edge effectively can pushing up artificial intraocular lenses of pushing pin to allow crystal thus complete is injected, when artificial intraocular lenses is installed in importing head, need down to press artificial intraocular lenses artificially, artificial intraocular lenses is contacted with bottom importing head cavity road, after importing head and injector are assembled, the bottom that the crystal of injector is pushed pin is a little less than the bottom importing tract in head, to be pushed pin the round and smooth process of head and import the inclined design in draught animals portion by crystal, crystal is pushed pin to enter smoothly and is imported head cavity road, such crystal is pushed pin in the process moved forward, can continue keeps pushing pin touches the bottom importing head.That is, need artificial intraocular lenses in the bottom importing head, crystal is pushed pin also in the bottom importing head, crystal is pushed pin and pushes up the efficient frontier of artificial intraocular lenses, just can complete and inject action.But pushing pin with the pushing portion of injector due to crystal is one or fixing dead, crystal is pushed pin and is had obvious pressure with the inwall importing head, the frictional resistance significantly coming from apparatus itself is there is in bolus infusion processes, this larger frictional resistance can increase the difficulty of surgical operation, is unfavorable for completing smoothly of operation.And the crystal of metal is pushed pin and be there is larger friction between the importing head of plastics and likely makes importing head produce the phenomenons such as chip comes off in whole bolus infusion processes, increase the risk in operation process.
Summary of the invention
The present invention is based on the above problem that exists in prior art and propose, the object of the invention is to reduce the operation easier in surgical process.And the present invention also aims to make to inject more smooth and easy, be conducive to the implantation of artificial intraocular lenses, that effectively reduces operating theater instruments itself injects resistance, reduces the additional risk in performing the operation.
