Description
Technical field
The present invention relates to a kind of importing heads for having crystal eye intraocular lens, are capable of providing the fold control of intraocular lens
System.The invention further relates to the implanted devices including the importing head.The invention further relates to will have crystal Pseudophakia to be loaded into lead
Enter the method in head.
Background technique
Crystal eye intraocular lens (PR-IOL) are a kind of artificial lens, are placed in the back room of eyes by implant surgery
(between iris and the front surface of natural lens), to improve the post-operative corrective eyesight of patient.PR-IOL after implantation with
It is intraocular that natural lens are retained in patient together.
Since PR-IOL is located at after the implantation between iris and the front surface of natural lens, and the preceding table of natural lens
Face is rendered as approximate spherical surface or aspherical convex shape, at the same the PR-IOL after being implanted into do not allow with before natural lens
(note: once PR-IOL is contacted with the front surface of natural lens, then will lead to natural lens has great probability for surface contact
Cataract occurs), therefore PR-IOL is usually designed to form as shown in Figure 1.Specifically, PR-IOL is laminar artificial
Crystalline lens.It is observed from the front the form of PR-IOL, is made of the support button loop on the centrally located circular light department of the Chinese Academy of Sciences and periphery.From side
The form of PR-IOL is observed in face, and in the upward structure of unilateral arch face, the center of arch face is the circular light department of the Chinese Academy of Sciences.Briefly, PR-
IOL is that form is rendered as that unilateral arch face is upward, is the circular light department of the Chinese Academy of Sciences at the center of arch face, be the thin slice that support is fastened with a rope, string, etc. on arch face periphery
Shape intraocular lens.Unilateral upward arch face structure can guarantee that the PR-IOL after implantation will not under the compressing of iris
It is contacted with the front surface of natural lens.PR-IOL can be process by a variety of flexible materials, such as silicone elastomer, hydrogel, third
Olefin(e) acid rouge etc..It is intraocular that the PR-IOL being process by flexible material can be implanted into patient by lesser operative incision.
It intraocularly needs PR-IOL implantation patient to manufacture operative incision in patient's cornea, then uses dedicated implanting device
Tool is completed PR-IOL being implanted to the intraocular operation of patient by operative incision.Currently widely used intraocular lens' implanted device
Complete the operation that PR-IOL implantation patient is intraocular.Intraocular lens' implanted device is usually made of importing head and propeller.It leads
Enter head and generally includes tubular body.Tubular body has through-lumen, and which defines intraocular lens' loading areas.When in use,
The distal end for importing the tubular body of head will pass through operative incision, intraocular so that PR-IOL is imported patient.Propeller is used for
The driving force for injecting PR-IOL is provided in importing process.Since PR-IOL is process for flexible material, and import passing through for head
Logical inner cavity is designed with specific cross section, so PR-IOL during by importing head that PR-IOL importing patient is intraocular
It can occur to fold or crimp and reduce its volume, so as to which (incision size is, for example, 3 mm left by lesser operative incision
It is right) import it is intraocular, fold or the PR-IOL of curling enter it is intraocular after can due to flexible material characteristic and be unfolded to revert to
Original free state.
In general, PR-IOL is supplied to doctor in the form individually packed, the PR-IOL in packaging is in unfolded original
Free state.Before implantation, doctor usually requires that PR-IOL is taken out and filled out of packaging using implantation tweezer or similar device
It is downloaded in the intraocular lens' loading area for importing head.PR-IOL can be loaded into import head intraocular lens' loading area it
Before, it is loaded during being loaded into the intraocular lens' loading area for importing head or being loaded into the intraocular lens for importing head
It is folded or is crimped after area.Hereafter, the importing head for being mounted with PR-IOL is assembled on propeller.Propeller offer is injected
Driving force, so that with the state that folds or crimp to enter patient by operative incision intraocular by PR-IOL.Into intraocular PR-IOL
Unfolded or curling original free state is reverted to by unfolded.The PR-IOL as made of flexible material is small, thin and smart
Close product, thus PR-IOL need with correctly fold or rolled state to enter patient intraocular.If PR-IOL is with incorrect
Folding or rolled state enter that patient is intraocular, then PR-IOL will be unfolded in a wrong manner, this likely results in needs
Taking-up be implanted the intraocular PR-IOL of patient or need within the eye to its it is further adjusted, so as to cause group around eyes
Wound is given birth in hair-weaving.It can be seen that PR-IOL is PR-IOL importing generation folding or curling in head with expected correct direction
Implant procedure success key.
PR-IOL is the central circular optical section arch face (edge upward so that PR-IOL in the correct placement mode imported in head
Z axis positive direction), while the long axis centerline of PR-IOL and the importing long axis centerline of head are consistent (note: consistent with Y-axis).At this
Wen Zhong, the direction about reference axis describe shown in Figure 2.PR-IOL is folded or the correct way of curling is the side X, optics area
To (i.e. short axle) two sides with the direction (i.e. Z axis negative direction) opposite with optical section arch face to PR-IOL long axis centerline (i.e. Y-axis side
To) fold or crimp.PR-IOL central circular optical section arch face after folding or crimping is not wrapped upward (along Z axis positive direction)
Folding is in intraocular implants' body.The PR-IOL for folding or crimping by this method can be easier and be more convenient to be unfolded and be restored to artificial
Lenticular original state.If PR-IOL is folded or is crimped with the direction opposite with above-mentioned correct direction, optical section
Arch face will be by packing PR-IOL after crimping.The intraocular PR-IOL of patient is squeezed into this rolled fashion to be on the one hand not easy
Expansion, probably because center light department of the Chinese Academy of Sciences arch face is constantly in curling squeezed state and is not easy to restore to original after being on the other hand unfolded
Beginning free state is possible to be constantly in the state of extrusion deformation, to need further to be adjusted and handled, increases
Cause patient's eye tissue that the risk of wound occurs.
There are mainly two types of the importing heads that can carry out PR-IOL implantation at present.The main difference of two kinds of importing heads is crystalline
The structure of body loading area, but by PR-IOL be placed on import head crystalline lens loading area method it is almost the same, now illustrate as
