Description

A kind of anterior chamber eyelid retractor used in penetrating keratoplasty

Technical field

The present invention relates to the anterior chamber's support used in the field of medical instrument technology, more particularly to a kind of penetrating keratoplasty Device.

Background technology

At present, clinically in cornea transplantation surgical procedure is carried out lesion to patient is had occurred and that, it is necessary to first take down Cornea tissue, extremely be easy to cause the tolerant abjection of intraocular in this process, so operates cumbersome, time-consuming and laborious, gives Medical worker adds great work difficulty.

The content of the invention

The present invention provides the anterior chamber's eyelid retractor used in a kind of penetrating keratoplasty, using the eyelid retractor of class ocular structure Anterior chamber is supported, the stabilization in front is ensure that, reduces the damage to periphery cornea, prevent the tolerant stream of intraocular after putting in a skylight Go out, make operation more safe efficient, the significantly relatively low work difficulty of medical worker, also improves the success rate of operation.

In order to solve the above technical problems, the embodiment of the present application provides the anterior chamber's branch used in a kind of penetrating keratoplasty Device, including button loop and central disc are supportted, further includes and takes out hole, button loop hole and graduation mark, button loop is equipped with the surrounding of the central disc, The front of central disc, which is equipped with, takes out hole and graduation mark, and the end face of button loop is equipped with button loop hole, and the quantity of the button loop is four, in pairs Claim distribution, the ultimate range diagonally fastened with a rope, string, etc. is 13mm, and the outer end of button loop is into shape is expanded, and the card of the button loop and central disc is into 5 degree Inclination angle, and rearward surface tilts, a diameter of 8mm of the central disc, two sides is concave surface, the taking-up pore size distribution In button loop and the junction of central disc, the circular aperture for being diameter 0.1mm, the button loop hole is ellipsoidal structure, size 0.2 × 0.2mm, the graduation mark are marked by the form of clock graduation mark, and the material of the button loop and central disc is hydrophilic Property acrylic acid.

The one or more technical solutions provided in the embodiment of the present application, have at least the following technical effects or advantages：

Anterior chamber is supported using the eyelid retractor of class ocular structure, the stabilization in front is ensure that, reduces to periphery cornea Damage, prevents the tolerant outflow of intraocular after putting in a skylight, makes operation more safe efficient, and the work of significantly relatively low medical worker is difficult Degree, also improves the success rate of operation.

Brief description of the drawings

In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing There is attached drawing needed in technology description to be briefly described, it should be apparent that, drawings in the following description are only this hairs Some bright embodiments, for those of ordinary skill in the art, without having to pay creative labor, can be with Other attached drawings are obtained according to these attached drawings.

Fig. 1 is the forward sight structure diagram of the embodiment of the present application；

Fig. 2 is the side elevational cross-section structure diagram of the embodiment of the present application.

In Fig. 1-Fig. 2,1, button loop, 2, take out hole, 3, central disc, 4, button loop hole, 5, graduation mark.

Embodiment

In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper Technical solution is stated to be described in detail.

As Figure 1-Figure 2, the anterior chamber's eyelid retractor used in a kind of penetrating keratoplasty described in the present embodiment, including Button loop 1 and central disc 3, further include and take out hole 2, button loop hole 4 and graduation mark 5, button loop 1 is equipped with the surrounding of the central disc 3, in Entreat the front of disk 3 to be equipped with and take out hole 2 and graduation mark 5,1 end face of fastening with a rope, string, etc. is equipped with button loop hole 4.

Wherein, in practical applications, the quantity of the button loop 1 is four, is symmetrically distributed, the ultimate range of diagonal button loop 1 For 13mm, fasten with a rope, string, etc. 1 outer end into shape is expanded, add the contact area with room angle, stationarity is good.

Wherein, in practical applications, the card of the button loop 1 and central disc 3 is into 5 degree of inclinations angle, and rearward surface inclines Tiltedly, it is corresponding with periphery corneal curvature, ensure stability of the eyelid retractor in anterior chamber, and reduce the damage to periphery cornea.

Wherein, in practical applications, a diameter of 8mm of the central disc 3, two sides are concave surface, reduce with above The contact of cornea, below crystal.

Wherein, in practical applications, the taking-up hole 2 is distributed in the junction of button loop 1 and central disc 3, is diameter The circular aperture of 0.1mm, facilitates the taking-up of eyelid retractor.

Wherein, in practical applications, the button loop hole 4 is ellipsoidal structure, and size is 0.2 × 0.1mm, is also easy for propping up Device is supportted to take out.

Wherein, in practical applications, the graduation mark 5 is marked by the form of clock graduation mark, and suture cornea is protected Hold symmetrical, reduction postoperative astigmatism.

Wherein, in practical applications, the material of the button loop 1 and central disc 3 is hydrophilic acrylic, and quality is soft, can Fold.

In use, after cut of performing the operation, can be from lateral incision（It is 2.2mm long）Anterior chamber is implanted into, is fixed on room angle, supported anterior chamber is prevented Intraocular holds outflow after only putting in a skylight, and can be taken out after donor's cornea fixes 4-8 pins from skylight opening.

The above described is only a preferred embodiment of the present invention, not make limitation in any form to the present invention, though So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification For the equivalent embodiment of equivalent variations, as long as being the content without departing from technical solution of the present invention, the technical spirit according to the present invention Any simple modification, equivalent change and modification made to above example, in the range of still falling within technical solution of the present invention.
