Abstract
This application discloses a kind of fixed devices of iris of eye protection equipment technology field; including annulus, screw rod and bearing; the lower end of annulus is equipped with the support leg that can be supported on eye profile; the quantity of screw rod is three; screw rod is connect with annulus screw thread, and screw rod runs through annulus, and bearing is located at screw rod towards on one end of circle ring center; the arc plate for fixing iris is connected on bearing, arc plate is recessed inwardly.This programme is by screw rod spinning in and out on annulus, so that driving arc plate to expand reduces its fixed range, and the rotation for limiting by bearing arc plate reduces the damage to ocular tissue compared with the technology of existing fixed iris.
Description
Technical field
The utility model relates to eyes to protect equipment technology field, and in particular to a kind of fixed device of iris.
Background technique
Iris belongs to eyeball middle layer, positioned at the forefront of tunica vasculose, in front of ciliary body, the size of pupil is adjusted, adjusts
Section enters the how many effect of intraocular light, and as a kind of biologic soft tissue material, iris has the viscoelastics such as lag, loose and creep
Characteristic.The important mechanical characteristic of iris makes it when eye traumas or eye congenital anomaly lead to aniridia or iridocoloboma, often goes out
Lose face the dysfunction of ball, such as spherical aberration, the increase of aberration, low visual acuity after diplopia, dazzle, photophobia, amblyopia and wound, and view are quick
Degree reduction etc..
In ophthalmic diagnosis and treatment, need adequately to operate the visual field, particularly with ultrasonic emulsification for cataract enucleation
Or for the ophthalmic operations such as vitrectomy for being related to eyeground, dissipates big pupil and stable iris is to provide sufficiently
Surgical field of view, smoothly complete the necessary guarantee of ophtalmic treatments, still, for iris relaxation syndrome patient, iris is preceding
It waves in room, influences surgical procedure, easily accidentally injure intraocular normal tissue, cause serious complication, influence the clinical efficacy for the treatment of.
Method currently used for expanding pupil and fixed iris mainly has: injecting viscoelastic agent into anterior chamber and directly expands pupil
Hole, iris tension are cut, multiple spot iris sphincter muscle is cut off, and existing method expands pupil and the effect of fixed iris is limited,
And it easily causes bleeding and inflammatory reaction, causes pupil to owe circle and sphincter pupillae tearing, cause postoperative pupil shape irregular
It or is in tension-free state.
Utility model content
The utility model is intended to provide a kind of fixed device of iris, easy during fixed iris to solve the prior art
The problem of damaging ocular tissue.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solutions: a kind of fixed device of iris, including
Annulus, screw rod and bearing, the lower end of the annulus are equipped with the support leg that can be supported on eye profile, and the quantity of the screw rod is
Three, the screw rod is connect with annulus screw thread, and the screw rod runs through annulus, and the bearing is located at screw rod one towards circle ring center
On end, the arc plate for fixing iris is connected on the bearing, the arc plate is recessed inwardly.
Working principle of the utility model is: support leg is supported on the eye profile of patient when using this programme, twist
Screw rod, screw rod will be rotating to movement at the center of annulus, and the effect of bearing is so that arc plate only can be to the center of annulus
Place's movement, without being rotated together with screw rod, after arc plate and iris contact, so that it may stopping twisting screw rod, and iris
It is also fixed at this time.
The utility model has the following beneficial effects: this programme passes through screw rod spinning in and out on annulus, to drive arc plate
Expand and reduce its fixed range, and the rotation for limiting by bearing arc plate subtracts compared with the technology of existing fixed iris
The damage to ocular tissue is lacked.
It is the optimization to basic technology scheme below:
Further, the quantity of the support leg is three.Three support legs again will not be too while making annulus more constant
Increase the weight of the fixed device of iris.
Further, the handle that the screw rod is equipped with convenient for operation.The spinning in and out of screw rod are controlled convenient for doctor in this way.
Further, the annulus is equipped with the magnifying glass for observing eye straight up.So during surgery convenient for doctor
The case where observing eye.
Further, the inside of the annulus is hollow, drug-feeding tube is connected on the annulus, the inside of the annulus is equipped with
Several medicine outlets, the drug-feeding tube and medicine outlet are connected to the inside of annulus.By drug-feeding tube, annulus and it can thus go out
The channel that medicine mouth is formed conveys medical fluid to eye.
Further, the two sides of the annulus are equipped with the eye speculum for strutting eyelid, and the eye speculum includes two downward
Inclined tilting bar, one end that the every tilting bar tilts down are connected with hang plate, and the angle between the tilting bar is small
Angle between hang plate.It oppresses two tilting bars when use to move toward one another, hang plate also just moves toward one another, and is moved to up and down
Between eyelid, tilting bar is unclamped, so that it may which, so that hang plate struts eyelid outward, eyelid struts the behaviour for being conducive to doctor
Make.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the fixed device of iris of the utility model；
Fig. 2 is the structural schematic diagram of eye speculum in a kind of fixed device of iris of the utility model.
Specific embodiment
Below by the further details of explanation of specific embodiment:
Appended drawing reference in Figure of description include: annulus 1, medicine outlet 2, arc plate 3, bearing 4, screw rod 5, drug-feeding tube 6,
Eye speculum 7, tilting bar 8, hang plate 9.
Embodiment is substantially as depicted in figs. 1 and 2: a kind of fixed device of iris, mainly by annulus 1, screw rod 5 and bearing 4 etc.
Constitute, annulus 1 is equipped with magnifying glass for observing eye straight up, the inside of annulus 1 be it is hollow, be connected on annulus 1 into
The inside of pencil 6, annulus 1 is equipped with several medicine outlets 2, and drug-feeding tube 6 and medicine outlet 2 are connected to the inside of annulus 1, annulus 1
Two sides are equipped with eye speculum 7 for strutting eyelid, and eye speculum 7 includes two tilting bars 8 tilted down, every tilting bar 8 to
Under inclined one end be connected with hang plate 9, the angle between tilting bar 8 be less than hang plate 9 between angle, the lower end of annulus 1
Equipped with the support leg that can be supported on eye profile, the quantity of the support leg in the present embodiment is three, and the quantity of screw rod 5 is three
Root, screw rod 5 are threadedly coupled with annulus 1, and screw rod 5 runs through annulus 1, the handle that screw rod 5 is equipped with convenient for operation, and bearing 4 is located at spiral shell
Bar 5 is connected with the arc plate 3 for fixing iris, arc plate 3 is recessed inwardly towards on the one end at 1 center of annulus on bearing 4.
When using this programme, first eyelid is strutted with eye speculum 7, concrete operation method be using when oppress two tilting bars
8 move toward one another, and hang plate 9 also just moves toward one another, and are moved between lower eyelid, unclamp tilting bar 8, so that it may so that hang plate
9 strut eyelid outward, and support leg is supported on the eye profile of patient again after eyelid is strutted, and twist on screw rod 5
Handle, screw rod 5 will be rotating at the center of annulus 1 and move, and the effect of bearing 4 so that 3 meetings of arc plate to annulus 1
It is moved at center, without being rotated together with screw rod 5, after arc plate 3 and iris contact, so that it may stop twisting screw rod 5,
And iris is also fixed at this time, when needing to be administered to eye during surgery, medical fluid enters from drug-feeding tube 6, passes through drug-feeding tube
6, the channel that annulus 1 and medicine outlet 2 are formed, medical fluid reach eye from medicine outlet 2, have reached the purpose of conveying medical fluid.
