Description

An examination table for ophthalmic treatment

technical field

The invention relates to the technical field of medical devices, in particular to an examination table for ophthalmic treatment.

Background technique

Ophthalmology is a discipline that studies the visual system, including the eyeball and its related tissues. Generally include vitreous, retinal diseases, optometry, glaucoma and optic neuropathy, cataract and other ophthalmic diseases. When performing ophthalmology diagnosis, an examination table is needed to carefully check the patient's eyes so that the patient's eyes can be viewed accurately and conveniently. When the existing examination table is in use, the patient's chin needs to be placed on the bracket to limit the movement of the head, and a suitable height is provided, so that the doctor can view the patient's eyes through the observation mirror. In actual use, due to the different ages and facial shapes of patients, different bracket heights and bracket shapes need to be adapted; here, for different patients, observations at different angles and distances are also required.

For example, the patent with the notification number CN212394886U discloses an examination table for ophthalmic treatment; it drives the arc-shaped supporting plate to lift up and down by twisting the screw to drive the lifting seat up and down to match the eye heights of different patients. The way of the sleeve drives the screw sleeves engaged on the outer sides of the studs at both ends to move away from or approach each other, so as to match the distance between the two observation mirrors and the width of the eyes of different patients. The patent with the notification number CN208770261U discloses an examination table for ophthalmic treatment, which fine-tunes the chin bracket so that the chin bracket can be driven by the fine-tuning screw to rotate under the rotation of the rotating disc, so that the chin bracket can be adjusted according to the medical care. Personnel require adjustments to diagnose patients more accurately.
