Description
Technical field
The present invention 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.
Summary of the invention
It is implanted into it is an object of the present invention to provide a kind of artificial lens and uses positioning hook, can be accurately positioned crystalline lens.
Based on the above issues, present invention provide the technical scheme that
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 invention has the advantages that
1, using technical solution of the present invention, several particles is equipped in positioning face, make positioning face in frosting, Ke Yizeng
Add tweezer head and lenticular frictional force, avoids crystalline lens in adjustment process from slipping, can be accurately adjusted lenticular position, drop
Low operation difficulty improves procedure efficiency；
2, using the further technical solution of the present invention, set hemisphere face for the positioning face on tweezer head, make positioning face with
Crystalline lens can be contacted effectively, and tweezer head can drag crystalline lens from side, be can be effectively prevented when adjusting posterior chamber phakic is stumbled and be not easy
The problem of dragging.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, required use in being described below to embodiment
Attached drawing be briefly described, drawings in the following description are only some embodiments of the invention, skill common for this field
For art personnel, without creative efforts, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the artificial Lens implantation positioning hook embodiment of the present invention；
Fig. 2 is the structural schematic diagram on tweezer head in the embodiment of the present invention；
Fig. 3 is the structural schematic diagram in another direction of tweezer head in the embodiment of the present invention；
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 present invention and be not limited to limit the scope of the invention.Implementation condition used in the examples can be done according to the condition of specific producer
Further adjustment, the implementation condition being not specified is usually the condition in routine experiment.
It is the structural schematic diagram of the embodiment of the present invention referring to Fig. 1-2, a kind of artificial lens implantation positioning hook, packet is provided
Handle portion 1, positioning bar 2 and tweezer head 3 are included, positioning bar 2 is fixed on the axial one end of handle portion 1, and tweezer head 3 is fixed at positioning
The end face of 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 implementation result of the invention, be not easy to drag when stumbling in order to avoid adjusting posterior chamber phakic is asked
Topic will adjust face 3-2 and be set as hemisphere face, can effectively contact, avoid with crystalline lens when 3 side of tweezer head drags crystalline lens
Crystalline lens slips, and 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
To extension, the second rod segment 2-2 is connect with the first rod segment 2-1 in angle, and the end of the second rod segment 2-2 is arranged in tweezer head 3, excellent
Choosing, which is 130~140 degree.
For ease of operation, anti-skid chequer 1-1 is equipped on the outer wall of handle portion 1.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
It is to can understand the content of the present invention and implement it accordingly, it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent transformation or modification that Spirit Essence is done, should be covered by the protection scope of the present invention.
