Abstract
The utility model discloses one kind to be used for ophthalmic lens subluxation pouch dilator, is made of the casing of steel wire and two or more；The steel wire is in the annular shape with opening, and steel wire both ends are bent to form bending part；Two or more the casings are actively socketed on the both ends of steel wire respectively and can slide along steel wire, and the bending part at steel wire both ends stops casing to be deviate from outward.Since the utility model is intraocular by the implantation of corneal limbus 1mm notch, and then it is unfolded, struts pouch, so that it is maintained the form of pouch during surgery, be unlikely to shrinkage in art, after the completion of lens extraction, device can be helped to recycle again by pushing away.The utility model sterilization can utilize repeatedly, and flexibility and resilience are good, damage to eye inner tissue small.
Description
Technical field
The utility model relates to medical fields, are used for ophthalmic lens subluxation pouch dilator more particularly to one kind.
Background technique
In ophthalmic lens operation, the stability of lens capsule bag is even more important for going on smoothly for operation.For
Subluxation of lens, partial relaxation or fracture due to apparatus suspensorius lentis, pouch ambitus and rear capsule are unstable, are easy in art
There is perfusion liquid and enter back room from suspensorium relaxation, makes back room pressure rise, Prevention and treatment enters anterior chamber, and glass occurs in anterior chamber
Glass body hernia, anterior chamber is deep mixed, Lens capsular shrinkage occurs, displacement, even ruptures, and is further exacerbated by intraocular pressure raising, and iris is de-
Out outside eye, operating difficulty is caused to increase, intraocular lens and capsular tension ring are difficult in phase implantation pouch.
Currently, clinically reach stable pouch often with capsular retractors or the fixed anterior lens capsule of iris hooks.But pouch
Capsule partial region before pull hook or iris hooks are only fixed, belongs to point-to-point support and fixes, equal for pouch ambitus and rear capsule
In vain, in zonular breaking or larger loose zone, Lens capsular is easier to pour in anterior chamber, causes anterior chamber unstable.
Utility model content
The purpose of this utility model is to provide one kind to be used for ophthalmic lens subluxation pouch dilator.
To achieve the above object, the technical solution of the utility model is:
The utility model is a kind of for ophthalmic lens subluxation pouch dilator, by the casing of steel wire and two or more
Composition；The steel wire is in the annular shape with opening, and steel wire both ends are bent to form bending part；Two or more the casings
It is actively socketed on the both ends of steel wire respectively and can be slided along steel wire, the bending part at steel wire both ends stops casing to be deviate from outward.
The steel wire annulus invagination is 90~270 degree across angle.
The casing is made of silica gel；The steel wire is made of memory titanium.
After adopting the above scheme, the casing as made of the utility model steel wire made of memory titanium and silica gel forms,
It is intraocular by the implantation of corneal limbus 1mm notch, and then be unfolded, pouch is strutted, so that it is maintained the form of pouch during surgery, is unlikely to
Shrinkage in art can help device to recycle after the completion of lens extraction again by pushing away.The product sterilization can utilize repeatedly, soft
Toughness and resilience are good, damage to eye inner tissue small.
The utility model is further described in the following with reference to the drawings and specific embodiments.
Detailed description of the invention
Fig. 1 is the front view of the utility model；
Fig. 2 is the side view of the utility model；
Fig. 3 is the state diagram in the utility model implantation lens capsule bag；
Fig. 4 is the state diagram of ambitus in the utility model implantation lens capsule bag.
Specific embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of for ophthalmic lens subluxation pouch dilator, by steel wire 1
It is formed with two casings 2.
The steel wire 1 is in the annular shape with opening, and 1 annulus invagination of steel wire is 90~270 degree across angle a, steel
It is as shown in Figure 4 that 1 both ends of silk are bent to form bending part 11(), 11 height of bending part is 1.5mm, remembers titanium steel silk according to different size
Different-diameter and different angle can be made.
Two casings 2 are actively socketed on the both ends of steel wire 1 respectively and can slide along steel wire 1,1 both ends of steel wire it is curved
Folding part 11 stops casing 2 to be deviate from outward.
In the present embodiment, the casing 2 is made of silica gel；The steel wire 1 is made of memory titanium.
Working principle of the utility model is:
1, as shown in figure 3, being implanted into state in 10 pouch of crystalline lens for steel wire 1, steel wire 1 enters anterior chamber from cut-out of limbus corneae,
Go out anterior chamber from another cut-out of limbus corneae by special drag hook, steel wire 1 progresses into before crystalline lens 10 before capsule, with intraocular lens
Positioning hook makes steel wire 1 enter 10 ambitus of crystalline lens.
2, as shown in figure 4, being implanted into ambitus in 10 pouch of crystalline lens for steel wire 1, by tensing silica gel sheath 2, receive steel wire 1
Contracting, the Forward of 10 pouch position of luxated lens, and then improve its dislocation state.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this
Range should still belong to this reality that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description
In the range of being covered with new patent.
Claims (3)
