Problems solved by technology

At present, the traditional method of anterior chamber puncture is to use a conventional eyelid speculum to open the eyelids, and to puncture the anterior chamber with a puncture needle under a microscope. However, at this time, the movement of the patient's eyeballs is not easy to control, and the iris or lens will be stabbed

Embodiment

[0011] Embodiment: Polymethyl methacrylate (PMMA) is made into the C type shown in the accompanying drawing by plastics process, and then pasted with soft pressing material (such as polyethylene) and adhesive plaster. In the experiment carried out on the rabbit eye, the surface of the rabbit eye is first anesthetized, and then the present invention is aligned with the eyeball and put into the eye, and the adhesive plaster is pasted outside the eye, so that the lid speculum is fixed on the eye. Then the anterior segment puncture operation was performed on the rabbit's eye, and the puncture needle was punctured through the anterior chamber through the opening of the C-shaped body.

Abstract

The invention provides an eyelid retractor which can fix eyeballs, and comprises a C type body (1), two arms (2), and components (3) which are adhered on the ends of an upper and a lower two arms and can be fixed on the skin, wherein the intra-annular diameter of the C type body (1) is the same as the diameter of an adult cornea, a base face of the C type body (1) is arranged at a radian at which the C type body (1) is in the anastomosis with a conjunctiva sac, and the C type body (1) of the eyelid retractor can be blocked at the edge of a corneosclera, thereby achieving the purpose of fixing eyeballs. The eyelid retractor can be used in the ophthalmic surgeries and/or ophthalmic examinations in which patients are asked to widely open eyes and keep fixed eyesight, such as the forward centesis, the anterior segment laser surgery, the optical coherence tomography technique (OTC) examination, the heidelberg retina tomograph (HRT) examination, the optic nerve fiber thickness analyzing (GDx) or the corneal endothelium counting.

Description

technical field [0001] The invention relates to an ophthalmic medical device, in particular to a lid speculum capable of fixing the eyeball. Background technique [0002] The eyelid speculum is a very important auxiliary device in the process of ophthalmic treatment and diagnosis. Its function is to help the doctor to open the patient's eyelid, which is convenient for the doctor to operate. However, the current eyelid speculum has simple functions and cannot fully meet the needs of eye examination, treatment and surgery. [0003] For example, anterior chamber puncture is a basic treatment in ophthalmology, and it is an important and effective method for treating acute eye diseases such as acute angle-closure glaucoma attack and retinal artery occlusion. At present, the traditional method of anterior chamber puncture is to use a conventional eyelid speculum to open the eyelids, and to puncture the anterior chamber with a puncture needle under a microscope. However, the movem...
