Abstract
The invention provides a kind of eye speculum of fixedly eyeball, comprise C type body (1) and two arms (2), and the end of two arms up and down be stained with can be on skin fixed parts (3), wherein the ring interior diameter of C type body (1) is suitable with adult's corneal diameter, and C type body (1) basal surface is the radian that matches with conjunctival sac.The C type body (1) of this eye speculum can be stuck in corneoscleral junction, thereby reaches the fixedly purpose of eyeball.This eye speculum can be used for needing the patient to open eyes wide and the ophthalmologic operation and/or ophthalmologic examination that keep looking admittedly in, as be used for the place ahead paracentesis, prosthomere laser surgery, means of optical coherence tomography (OCT) inspection, Heidelberg retina tomoscan (HRT) checks that optic nerve fiber thickness is analyzed (GDx) or corneal endothelium counting.
Description
Technical field
The present invention relates to a kind of ophthalmic medical apparatus and instruments, specifically a kind of eye speculum of fixedly eyeball.
Background technology
Eye speculum is a very important assistive device in ophtalmic treatments and the diagnostic procedure, and its effect is to help the doctor to strut patient's eyelid, makes things convenient for the doctor to operate.But present eye speculum function is simple, can not satisfy the needs of ophthalmologic examination, treatment and operation fully.
For example, paracentesis of anterior chamber is a base therapy measure of ophthalmology, is the important of acute oculopathy such as treatment acute angle closure glaucoma stage of attack, retinal artery occlusion and effective method.The traditional method of carrying out paracentesis of anterior chamber at present is to strut eyelid with conventional eye speculum, at microscopically with the lancet puncture anterior chamber, but this moment, the motion of patient's eyeball was wayward, iris or crystalline lens are stabbed in careless slightly meeting, cause severe complications such as iris damage or traumatic cataract, therefore, paracentesis of anterior chamber is had relatively high expectations to doctor's technical merit.These have limited this The Application of Technology scope, especially can limit it and carry out at basic hospital, might incur loss through delay patient's treatment opportunity.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provide a kind of can be when strutting eyelid the fixing eye speculum of eyeball, to improve operability, safety and the accuracy of ophthalmologic operation and inspection.
The present invention includes a C type body 1 and two arms 2, and the end of two arms up and down be stained with can be on skin fixed parts 3.The ring interior diameter 4 of above-mentioned C type body is suitable with adult's corneal diameter, can be 11～13mm, preferred 12mm.Be the radian that matches with conjunctival sac at C type body basal surface, its radius of curvature can be 22cm～26cm, preferred 24cm.The opening vacancy of C type body can be 45 °～75 °, preferred 60 °.C type body is made by physiologically acceptable material, as selects macromolecular material polymethyl methacrylate (PMMA) for use.Arm can be made by soft pressure material, and fixed parts can be adhesive plaster on skin.
With the paracentesis of anterior chamber is example, when use is of the present invention, earlier the eye speculum body is put into conjunctival sac after topical anesthesia, and C type opening is as for the temporo side, and soft arm can draw back eyelid, and with immobilization with adhesive tape.Because eyeball 5 surperficial corneas are different with the curvature of sclera, therefore can form an annular depression at corneoscleral junction 6 places, when use was of the present invention, the C type body of eye speculum can be stuck in corneoscleral junction, thereby reach the fixedly purpose of eyeball, and then with puncture needle from C type body opening puncture anterior chamber.
Except that paracentesis of anterior chamber, known to those skilled in the art, the present invention can be used on that any patient of needs opens eyes wide and the operation that keeps looking admittedly and checking, check as prosthomere laser surgery, OCT (means of optical coherence tomography), Heidelberg retina tomoscan (HRT) is checked, optic nerve fiber thickness is analyzed (GDx), corneal endothelium counting etc.

The specific embodiment
The present invention is described in more detail below in conjunction with drawings and Examples.
Embodiment: by plastic process polymethyl methacrylate (PMMA) is made C type shown in the drawings, stick soft pressure material (as polyethylene) and adhesive plaster again.In the experiment that lagophthalmos is carried out, earlier with the lagophthalmos topical anesthesia, then the present invention is aimed at eyeball and put into ophthalmic, adhesive plaster is attached to outside the eye, thereby eye speculum is fixed on the eyes.Then lagophthalmos is carried out prosthomere puncture operation, from C type body opening puncture anterior chamber, in operation process, lagophthalmos is in good stationary state always, and operation is carried out smoothly with puncture needle.
