Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a darkroom measurement strabismus degree fixation lamp. BACKGROUND

[0002] Strabismus refers to the coordination of eye muscle movement disorder caused by the inability of both eyes to fixate on the same object at the same time, which is caused by congenital or acquired factors. Since strabismus is not conducive to the normal realization of eye function and is very strange in appearance, which affects the social life of patients, it is very important to accurately measure the degree of strabismus and correct it.

[0003] In the prior art, corneal reflection method is often used to measure the degree of strabismus of strabismus patients. The main operation of this method is to fix a stable light source at 33 cm from the patient in the darkroom, and let the patient fixate on the light source at 33 cm. The medical staff observes the corneal reflection point, and according to the position of the corneal reflection point deviating from the pupil center, the degree of strabismus is roughly judged. If the light source is eccentric by 1 mm, the deviation meter is 7.5 degrees or 15 pd.

[0004] At present, the position data of the corneal reflection point deviating from the pupil center obtained by the medical staff through long-distance observation in the corneal reflection method is rough data, which has a large error compared with the true value. The operation of strabismus correction requires more accurate specific value of strabismus degree, so the measurement data obtained by manual observation is easy to lead to correction failure, and the manual measurement cannot quickly and accurately obtain the data. The eyeball will shake when measuring due to the light source, and the accurate change is difficult to capture by manual observation, so that the accurate position of the pupil center is difficult to determine, resulting in difficulty in measurement.

A strabismus degree display 13 is fixedly arranged on the right side of the comprehensive control frame, the strabismus degree display comprises an electric moving indicating needle 14 and a strabismus degree display bar 15, the electric moving indicating needle is made by fixedly arranging the indicating needle on the electric telescopic push rod, a comprehensive control center 16 is fixedly arranged at the lower end of the strabismus degree display, the comprehensive control center comprises a control chip and a control panel, an auxiliary recording lamp 17 is fixedly arranged below the comprehensive control center, a data recording and writing table 18 is fixedly arranged below the auxiliary recording lamp, a rechargeable battery is assembled and arranged in the comprehensive control frame, the comprehensive control center is connected with the rechargeable battery, the auxiliary recording lamp, the electric rotating plate, the electric telescopic rod, the adjusting fixation lamp, the pupil recognition instrument and the strabismus degree display through lines respectively.

[0032] When the embodiment is implemented, first, the whole device is started, then the patient is asked to sit on the seat, and after sitting, the pupil recognition instrument is worn on the head, then the lens of the eye movement instrument on the side to be measured for strabismus is turned to be directly opposite to the eyeball of the patient, then the electric rotating plate is controlled to rotate and the adjusting fixation lamp is controlled to be directly opposite to the eye of the patient by inputting instructions to the comprehensive control center, then the patient is controlled to make the eyeball to be tested for strabismus directly opposite to the bulb on the adjusting fixation lamp, the bulb is named as bulb A, then the shift between the pupil center and the reflection point of bulb A is observed, at this time, another adjusting bulb on the adjusting fixation lamp is lit according to the shift, and the patient is asked to look at the adjusting bulb with the eyeball to be tested for strabismus, at this time, the pupil of the patient is observed to move, the appropriate adjusting bulb is selected according to the movement of the eyeball of the patient, and finally the pupil center of the patient is moved to the position where the reflection point of bulb A is coincided, and it is noted that only two bulbs are lit in the process, one is bulb A which is never turned off, and the other is the adjusting bulb on the adjusting fixation lamp which is changed constantly and finally determined by the comprehensive controller, and the final adjusting bulb is the bulb which can make the pupil center of the patient coincide with bulb A when the patient looks at it.

[0033] When the pupil center of the patient and the reflection point of bulb A on the eyeball of the patient are coincided, the eye movement instrument is started to measure by the comprehensive control center, when the eye movement instrument is started, the medical staff controls the comprehensive control center to turn off the adjusting bulb, and simultaneously asks the patient to change from looking at the adjusting bulb to looking at bulb A, when the patient stably looks at bulb A, the eye movement instrument completes data collection, and the collected data is fed back to the comprehensive control center through the line, the comprehensive control center issues instructions to the strabismus display according to the data fed back by the eye movement instrument, so that the pointer of the strabismus display points to the specific scale of the strabismus number indicating scale under the action of the electric telescopic push rod, and the strabismus number is displayed, and the medical staff records the strabismus number of the patient on the data recording table, and the operation is completed.

[0034] It is particularly pointed out here that the information recorded and transmitted by the eye movement instrument is the distance of the movement of the pupil center, so the distance of the telescopic distance of the electric telescopic push rod controlled by the comprehensive control center is also the same distance as the distance value transmitted, and finally the reason why the strabismus is read out is that the distance value between the pupil center and the reflection point has a fixed quantitative relationship with the strabismus, so the strabismus number indicating scale is obtained through quantitative relationship conversion, so although the pointer indicates the distance, the strabismus number directly read on the scale is indeed the strabismus number. In the embodiment, the light source is eccentric by one millimeter, and the deviation meter is 7.5 degrees.

[0035] The embodiment designs an eye tracker and an adjusting annotation lamp combination to utilize a comprehensive controller for real-time control, so that the eye tracker accurately captures and identifies the pupil center position, and the adjusting annotation lamp adjusts the light position change to cooperate with the patient's eyeball rotation to accurately control the initial position of the reflection point to be in the pupil center. Therefore, the starting position data of the measurement is accurate, so that the overall operation does not require manual measurement, the measurement data is accurate and intuitive, greatly increases the accuracy of strabismus correction surgery, and improves the success rate of the surgery.
