Description
Technical field
The utility model relates to artificial lens implanted prosthetics field, in particular to a kind of artificial lens implantation positioning hook.
Background technique
" implantable contact lenses " (foreign language abbreviation: ICL, foreign language full name: Implantable CollamerLens), it
It is current safety, high-end myoporthosis scheme.It is different from laser and other cutting operations of corneal tissue, its not cutting angle
Film, it is by Minimally Invasive Surgery that Lens implantation is intraocular, it is not damaged to cornea.Eyesight is apparent after correction, is near-sightedness correction technology
New trend.The process of ICL lens implantation is simultaneously uncomplicated, is very important safely, it is necessary to by consummate Microsurgical Techniques,
Doctor's operation of surgical apparatus, abundant surgical experience.Operation mainly has three steps:
1, firstly, the position between the white and black of eyes makes a small notch.
2, then, to intraocularly injecting a kind of gel protection eye inner tissue, then ICL injected intraocular.
3, ICL carefully then, is adjusted to facies posterior iridis, and by gel from intraocularly going out.
When ICL crystalline lens is carefully adjusted to facies posterior iridis by step 3, need to transpose hook to adjust lenticular position.
In the prior art transpose hook tweezer head positioning face be plane, cannot effectively and lens contact, thus can not
It is accurately positioned crystalline lens.
Utility model content
The utility model aim is to provide a kind of artificial lens implantation positioning hook, can be accurately positioned crystalline lens.
Based on the above issues, technical solution provided by the utility model is:
Artificial lens implantation positioning hook, comprising:
Handle portion；
Positioning bar, is fixed on handle portion axial direction one end；And
Tweezer head is fixed at the end of the positioning bar；
The positioning face on the tweezer head is equipped with several particles, so that the positioning face is in frosting.
In one of them embodiment, the partial size of the particle is 0.0048mm~0.0058mm.
In one of them embodiment, the positioning face on the tweezer head is in hemisphere face.
In one of them embodiment, the positioning bar includes the first rod segment and the second rod segment, first rod segment edge
The handle portion is axially extending, connects between second rod segment and first rod segment in angle, and the tweezer head setting exists
The end of second rod segment.
In one of them embodiment, the angle is 130~140 degree.
In one of them embodiment, the outer wall of the handle portion is equipped with anti-skid chequer.
Compared with prior art, the utility model has the advantages that:
1, using the technical solution of the utility model, several particles is equipped in positioning face, make positioning face in frosting, it can
To increase tweezer head and lenticular frictional force, avoids crystalline lens in adjustment process from slipping, can be accurately adjusted lenticular position
It sets, reduces operation difficulty, improve procedure efficiency；
2, using the further technical solution of the utility model, hemisphere face is set by the positioning face on tweezer head, makes to transpose
Face can effectively be contacted with crystalline lens, and tweezer head can drag crystalline lens from side, be can be effectively prevented and adjusted posterior chamber phakic when stumbling
It is not easy the problem of dragging.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical solution of the utility model embodiment
The attached drawing used is briefly described, and the drawings in the following description are merely some embodiments of the present invention, for ability
For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other attached
Figure.
Fig. 1 is the structural schematic diagram of the utility model artificial lens implantation positioning hook embodiment；
Fig. 2 is the structural schematic diagram on tweezer head in the utility model embodiment；
Fig. 3 is the structural schematic diagram in another direction of tweezer head in the utility model embodiment；
Wherein:
1, handle portion；1-1, anti-skid chequer；
2, positioning bar；2-1, the first rod segment；2-2, the second rod segment；
3, tweezer head；3-1, particle；3-2, positioning face.
Specific embodiment
Above scheme is described further below in conjunction with specific embodiment.It should be understood that these embodiments are for illustrating
The utility model and be not limited to limitation the scope of the utility model.Implementation condition used in the examples can be according to specific producer
Condition do further adjustment, the implementation condition being not specified is usually the condition in routine experiment.
It is the structural schematic diagram of the utility model embodiment referring to Fig. 1-2, a kind of artificial lens implantation positioning is provided
Hook, including handle portion 1, positioning bar 2 and tweezer head 3, positioning bar 2 are fixed on the axial one end of handle portion 1, and tweezer head 3 is fixedly installed
In the end face of positioning bar 2, in use, by tweezer head 3 and lens contact to adjust lenticular position.
Crystalline lens must be positioned in order to accurate, avoids crystalline lens in adjustment process from slipping, is set on the positioning face 3-2 on tweezer head 3
There is several particles 3-1, so that positioning face is in frosting, positioning face 3-2 refers to the face of tweezer head and lens contact, from
And increase tweezer head 2 and lenticular frictional force, it avoids crystalline lens from slipping in adjustment process, realizes lenticular accurate tune
Section reduces operation difficulty, improves procedure efficiency.In this example, the partial size of particle 3-1 is 0.0048mm~0.0058mm, due to crystalline substance
Body making material is Collamer, this is a kind of unique body crystalline material.This dedicated crystalline material has than propylene
Acid and the higher biocompatibility of silica gel and toughness will lead to crystalline lens scuffing as fruit granule is excessive, it is insufficient to cross less friction.
In order to advanced optimize the implementation result of the utility model, it is not easy to drag in order to avoid adjusting when posterior chamber phakic is stumbled
The problem of, face 3-2 will be adjusted and be set as hemisphere face, can effectively be contacted with crystalline lens when 3 side of tweezer head drags crystalline lens,
It avoids crystalline lens from slipping, realizes lenticular accurate positioning.
In this example, adjusting rod 2 includes the first rod segment 2-1 and the second rod segment 2-2, wherein the first rod segment 2-1 is along 1 axis of handle portion
