Description

Auxiliary support for optimizing ophthalmological ultrasonic examination

Technical Field

The utility model belongs to the technical field of medical ophthalmology auxiliary technology and specifically relates to an optimize auxiliary stand of ophthalmology ultrasonic examination.

Background

The ophthalmic ultrasonic examination comprises a type of examination with great diagnostic value, and B-ultrasonic examination and A-ultrasonic examination are commonly developed. The B-mode ultrasonography is of great significance for some eye diseases with turbid refractive medium of eyes, such as cataract, corneal edema, hyphema, and the like, as well as retinal diseases, tumors in eyes, and the like. Meanwhile, the intraocular lens degree needs to be calculated before cataract operation, and research shows that accurate eye axis measurement can greatly reduce refractive error after cataract operation. Currently, devices clinically used for ocular axis measurement include optical devices represented by an optical biological measurement instrument and an ultrasound for measuring the ocular axis based on the acoustic principle. Due to the fact that refractive media are turbid and eyeballs have poor vision fixation, optical equipment has limitations, and the A ultrasonic measurement eye axis has an irreplaceable position in pre-cataract operation examination.

The eye axis measurement obtained for a-mode is the distance between the central anterior surface of the cornea to the limiting membrane within the retina. Before measurement, the eye surface anesthetic is dropped into the eyelid of a patient, the patient lies flat, and an inspector holds the ultrasonic probe A and is parallel to the corneal vertex section and vertical to the visual axis. At present, the accuracy of the contact type A ultrasonic measurement eye axis usually depends on the experience of an inspector, namely, the suspension operation of the arm is stable, the A ultrasonic probe is parallel to the corneal vertex section, and the cornea is not pressed as much as possible. However, during the measurement, the a-ultrasonic probe may contact the cornea of the patient, and when the patient is not fit well, the eyeball frequently rotates or the hand is unstable due to insufficient experience of the examiner or frequent operation of the examiner, fatigue of the suspended arm will cause the a-ultrasonic probe to contact the cornea of the patient and decrease the stability, so as to form a vertical compression of the cornea or an oblique compression of the cornea in a direction inclined to the corneal vertex section, thereby causing inaccurate measurement of the ocular axis. In addition, since B-ultrasonic examination is widely used in ophthalmology, many hundreds of B-ultrasonic examinations are required daily by examiners, and the long-term operation of the examiners causes discomfort of the shoulder and elbow such as scapulohumeral periarthritis due to the continuous suspension of the arms.

The Chinese patent application: CN208259682U discloses a multifunctional ophthalmic examination device. The multifunctional ophthalmic-examination device includes: a table top; the drawer is gone into to the card in the lower extreme recess of mesa, it is connected with the auxiliary stand to drag the jaw board with the fix with screw on the mesa, the flexible post of installation in the recess that corresponds on the auxiliary stand, installation knob in the corresponding screw thread cylinder hole of flexible post, the terminal for the screw installation inspection instrument of flexible post, there is spherical ball on the flexible post, the device mainly solves current detection device and needs the patient to aim at the instrument for a long time, and often remove the observation position, lead to the problem that the patient is fatigued, but the device wholly benefits from the patient to use, and the staff to ophthalmic inspection is not practical.

In summary, there is a need for an auxiliary support for optimizing ophthalmic ultrasonic examination, which has a simple structure and is convenient to operate, and can improve the hand operation stability of an examiner, improve the accuracy of a-ultrasonic axis measurement and reduce operator fatigue.
