Abstract
The utility model provides a multifunctional eyelid retractor which is used for corneal transplantation and superficial corneal lens operation. The eyelid hook adjusting device comprises a frame (2), an eyelid hook (1), an eyelid hook adjusting nut (3), a corneal ring (6), a corneal ring arm (5) connected with the corneal ring arm, and a corneal ring adjusting nut (4). The eyelid retractor is characterized in that the eyelid retractor and the eyeball are fixed into a whole, and the eyelid and the eyeball can be lifted lightly through the eyelid hook adjusting nut (3) and the periosteum ring adjusting nut (4) according to needs so as to reduce intraocular pressure and be beneficial to surgical operation. The utility model has the advantages of reasonable design, simple structure, convenient use and easy disinfection, and is beneficial to improving the success rate of corneal transplantation and surface corneal keratoplasty and reducing the occurrence of complications.
Description
This utility model provides a kind of multi-functional eye speculum, is used for corneal transplantation and epikeratophakia, relates to machinery and medical domain.
Corneal transplantation is the important means that the corneal blindness patient recovers lost eyesight, and in operation process, opening eyelid and eyeball fixing often is important step.At present common eye speculums or sutures of adopting are opened fixedly eyeball of eyelid and corneal ring more, and the former normal pressure is compeled eyeball and caused that intraocular pressure increases, and the latter often makes eyeball fixing not ideal enough, so that influence is performed the operation and carried out smoothly.
This utility model is to overcome above-mentioned shortcoming, provides a kind of and opens eyelid and eyeball is fixed in one, and it is convenient to open eyelid, oppression eyeball not, and eyeball is fixing reliable, and the multi-functional eye speculum of the effect that promotes eyeball is arranged.
The technical solution adopted in the utility model is to utilize the supporting role of framework (2), make eyelid hook (1) and corneal ring (6) be in the appropriate location respectively by eyelid hook adjusting nut (3) and corneal ring adjusting nut (4), eyelid is separated on both sides up and down, fully expose cornea, gently carry simultaneously eyelid and eyeball, reduce intraocular pressure.About this eye speculum, left-right symmetric, easy to use.This eye speculum adopts the manufacturing of high-quality rustless steel, is convenient to soak, stifling and autoclave sterilization.
Advantage of the present utility model: 1, this utility model collection is opened eyelid and eyeball is fixed in one, and is easy to use, simplifies surgical operation step.2, this eye speculum is provided with 2 eyelid hook adjusting nuts (3) and 4 corneal ring adjusting nuts (4), makes fissura palpebrae and eyeball position be suitable for operation.Each adjusting nut below is provided with spring (8), is convenient to regulate.3, this eye speculum adopts the manufacturing of high-quality rustless steel, is convenient to soak, stifling and autoclave sterilization.4, this eye speculum is reasonable in design, and structure is tightly played, and price is low, easily promotes.
Description of drawings:
Fig. 1 is a stereogram of the present utility model
Fig. 2 is a front schematic view of the present utility model
Fig. 3 is a side schematic view of the present utility model
The example of describing is in conjunction with the accompanying drawings explained the present invention:
As Fig. 1, Fig. 2, shown in Figure 3, this utility model is by framework (2), eyelid hook (1) and eyelid hook adjusting nut (3), corneal ring (6) and corneal ring arm (5) and corneal ring adjusting nut (4) are formed up and down.Framework (2) upper and lower frames middle part is provided with screw eyelid hook screw and matches, the distance of adjusting nut (3) may command eyelid hook (1) and framework (2).The screw that is respectively equipped with on two screws and the corneal ring arm on framework (2) two side frames matches, the distance of adjusting nut (4) may command corneal ring (6) and framework (2).Two side frames middle part is the arcuation depression downwards, is convenient to patient's operation.Eyelid hook (1) is " S " shape, and inner broad is arcuation, and in order to hook eyelid, the outer end is upturned, and in order to adjust eyelid hook position, eyelid hook (1) middle part is that a rectangle penetrates groove (7), adjusts eyelid hook (1) and free length thereof with control fissura palpebrae size.The corneal ring arm (5) that is mutually 90 ° is arranged on the corneal ring (6), and inner and cornea boxing is an one, and the outer end is provided with screw and screw coincide, and regulates corneal ring adjusting nut (4) corneal ring (6) is seesawed.Each screw middle and lower part is with spring (8), is convenient to the adjusting of nut (3,4).During use, according to patient's brow ridge height and the protruding sunken degree of eyeball, earlier the upper eyelid is drawn back, taking advantage of a situation retracts palpebra inferior, adjusts eyelid hook (1) and eyelid adjusting nut (3) fissura palpebrae is fully opened greatly, and cornea fully exposes.Adjust corneal ring adjusting nut (4) then, make just position limbus of corneae portion of corneal ring, with 12,6,3,9 clock orientation ring is fixed on bulbar conjunctiva respectively, thereby eyeball is fixed.The operation that undergos surgery that continues.
