Abstract

The invention belongs to the field of ophthalmology, and particularly relates to an ophthalmic injection and extraction device, aiming to solve the problems that existing rubber plugs are not mountedfirmly and syringe needles cannot be fastened. The ophthalmic injection and extraction device comprises a needle tube. A rubber plug is arranged in the needle tube. A pull rod is mounted on one side of the rubber plug, and a pull block is arranged at one end of the pull rod. An injection tube is arranged on one side of the needle tube, and a syringe needle movably sleeves the injection tube. A clamping plate sleeves the syringe needle, and a T-shaped hole is formed in the pull rod. A connection block is fixedly mounted on one side of the rubber plug, a connection rod is fixedly mounted on oneside of the connection block, and a connection groove is formed in one side of the pull block. The ophthalmic injection and extraction device has the advantages that an insertion rod is inserted intoa slot to complete mounting of the rubber plug, and the insertion mode can make the rubber plug mounted more firmly than conventional clamping modes; the syringe needle is clamped by an arc-shaped plate, unstable mounting of the syringe needle can be avoided, and people's demands are met.

Description

Technical field [0001] The invention relates to the technical field of ophthalmology, in particular to an ophthalmic injection extraction device. Background technique [0002] The full name of Ophthalmology is "Ophthalmology Specialty", which is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. Ophthalmology generally studies vitreous, retinal diseases, ophthalmology, glaucoma and optic neuropathy, cataracts and many other subjects. Eye diseases. [0003] Generally, the injection extraction device refers to a commonly used syringe. However, in the prior art, the rubber stopper in the syringe is mostly installed by means of snapping. This causes the rubber stopper and the pulling rod to be separated easily if improper force is applied, and then As a result, the syringe is scrapped, and the needle is mostly directly sleeved on the injection tube. If the installation is not in place, pushing the pull rod to drive the...
