Description
Technical field
Present invention relates particularly to cataract and artificial lens technical field, and in particular to a kind of Combined detachable is replaceable
The intraocular lens system of optical section.
Background technology
Cataract refers to a kind of disease of eye caused by being lost due to the transparency of human lens.At present for this
Unique radical cure means of eye disease are to be surgically removed muddy crystalline lens and substituted by artificial artificial lens.Intend the artificial of implantation
The number of degrees of crystal are calculated and are obtained by artificial lens calculation formula according to the measurement of the preoperative biological parameter to eyes.So
And often there is certain error and uncertainty in this calculating, lead to after cataract operation that there are refractive errors, influence patient
Eyesight.There is high myopia, hyperpresbyopia in postcataract refractive error, have cornea refractive surgery history and preoperative in the preoperative
Other factors lead to not especially common in the accurately cataract patient of the biological parameter of measurement eyes.For less than 2 years old
After infant's cataract operation cannot a phase implantable artificial crystal, need after 2 years old through secondary operation implantable artificial crystal.
In addition, children or teen-age postcataract cause since eyeball is constantly in development at postoperative refractive diopter
In the unstable state of variation, need to be corrected by other correction of refractive errors means or replacement artificial lens.It is worth noting
, the optimum position of artificial lens implantation is in lenticular pouch, however fibrosis easily occurs for postcataract pouch
Adhesion is implanted into or is replaced artificial lens to the second stage of artificial lens and bring great difficulty, be easy to cause second operation damage simultaneously
Lead to the appearance of the complication such as pouch rupture.
Therefore, if above-mentioned deposit can be solved perfectly by designing a kind of artificial lens of the replaceable optical section of Combined detachable
The problem of：By folding artificial lens holder（Carrier）Pass through smaller operative incision Permanent implantation pouch by injector
In, folding optical section can be injected implantation intraocular by operative incision and be locked with bracket assembled by secondary operation；Or
It is postoperative to find there are when serious refractive error, optical section unlock and is unloaded to take out by smaller operative incision, then be implanted into more
The optical section changed is re-assemblied.Operation is repeated several times to can be completed by smaller operative incision, it will not be to pouch and eye
Its interior hetero-organization causes additional damage, and since the stability of permanent support can ensure that the position of group iol cartridge is kept
Constant normotopia.
Invention content
It is in order to solve the defects of prior art and insufficient.The present invention provides a kind of replaceable optical sections of Combined detachable

Slot, the limited block are wedge block, and the limited block is screwed in open slot to be coordinated with limiting tooth limit.
It is additionally provided on the replaceable optical section for replaceable optical section installing and dismounting and the positioning of the optical section of positioning
Hole.
The optical section positioning hole is two circular holes through replaceable optical section, and the circular hole described in two is symmetrical arranged
At the both ends of replaceable optical section.
The outside support and replaceable optical section are all made of same material and are made.
The outside support and replaceable optical section are all made of flexible optical material and are made, and can fold and be loaded in accordingly
Infusing device in be implanted into.
The side of the outside support is additionally provided with 4 symmetrically arranged projection portions, forms the foot button loop of outside support, will
Outside support is fixed in the pouch of crystal.
The beneficial effects of the invention are as follows：The present invention provides a kind of artificial lens of the replaceable optical section of Combined detachable
System replaces optical section and outside by the replaceable optical section that outside support is arranged and is removably mounted on outside support
Be screwed on cooperation between holder, only needs to reach correction without replacing whole artificial lens by replacing optical section to realize
The purpose of postoperative artificial lens refractive error, or for the needs for the treatment of by stages, can priority implantable artificial crystal holer and
Replaceable optical section, to make multiplicating surgical procedure become safer, simple, convenient.
