Embodiment 1

[0046] Example 1: Reference figure 1 , image 3 with Figure 4 , An optical coherence tomography scanner for ophthalmology, comprising a base 3, a driving mechanism 7 and an optical head assembly 1 arranged in order from bottom to top. The driving mechanism 7 includes three motors, so that the optical head assembly 1 arranged on the driving mechanism 7 can move up and down, forward and backward, and left and right. The optical head assembly 1 is equipped with an iris camera group 11, which is used for shooting. The eye surface of the tested object and the image including the optical head assembly 1; a controller 34 is installed in the base 3, and the controller 34 calculates the distance that the optical head assembly 1 needs to move based on the images taken by the iris camera group 11, and then The driving mechanism 7 is controlled so that the driving mechanism 7 drives the optical head assembly 1 to move to a corresponding position. The iris camera group 11 and the controlle...

Embodiment 2

[0048] Example 2, reference figure 1 with figure 2 , An ophthalmic optical coherence tomography scanner, further comprising a forehead rest and jaw rest assembly vertically arranged on one side of the base 3, the forehead rest and jaw rest assembly includes a forehead rest 4 and a jaw rest 5, the chin of the tested person is placed on the jaw On the support 5, the forehead is in contact with the forehead support 4, thus positioning the head of the tested person. The forehead support and jaw support assembly also includes a drive motor, which is used to drive the forehead support and jaw support assembly to move. The forehead support and jaw support assembly has an independent motion control structure to control the movement of the drive motor. The function is to work with the drive mechanism 7 to automatically adjust the measured The eyes of the person demand the relative position with the optical head assembly 1. The optical head assembly 1 includes a housing and an eyepiece ...

Embodiment 3

[0058] Example 3, reference Image 6 , An eye scan image acquisition method of an ophthalmic optical coherence tomography scanner, comprising the following steps:

[0059] 1. Turn on the device, connect the device to an external power supply, and supply power to all electrical components so that all electrical components can work. The electrical components include: scanner 31, voice player 32, controller 34, drive mechanism 7. Optical Head assembly 1;

[0060] 2. The code scanner 31 reads the information of the person under test, and the person under test aligns the barcode or QR code with the scanning port of the code scanner 31. After the code scanner 31 reads the scanned information, the information is entered into the controller 34 ;

[0061] 3. Turn on the voice player 32, the controller 34 controls the voice player 32 to play the voice, and the voice includes prompting the tested person to place the head on the forehead rest and jaw rest component;

[0062] 4. The iris camera g...

Abstract

The invention discloses an ophthalmic optical coherence tomography scanner and an eye scanning image acquisition method, and relates to the field of medical instruments. The ophthalmic optical coherence tomography scanner comprises a controller, a base, a driving mechanism arranged on the base and an optical head assembly arranged on the driving mechanism, wherein the optical head assembly is provided with an iris camera group; the controller can position the ocular surface according to an iris image, collected by the iris camera group, of a detected object and control the driving mechanism todrive the optical head assembly to move according to a positioning result, so that the optical head assembly can obtain an eye scanning image of the detected object. The position of the optical headassembly is automatically adjusted instead of being manually adjusted, so that the effect of improving the detection efficiency and precision of the optical head assembly is achieved.

Description

Technical field [0001] The invention relates to the field of medical equipment, and more specifically, it relates to an ophthalmology optical coherence tomography scanner and an ocular scanning image acquisition method. Background technique [0002] Optical coherence tomography is abbreviated as OCT. It is a device that performs diagnostic imaging through optical principles. It can provide images of cross-sections of the retina for objective quantitative measurement and qualitative clinical analysis when detecting glaucoma and retinopathy. [0003] The Chinese patent with the publication number CN103371797B discloses an ophthalmological device, which includes a base; a stand, which is set on the base and can be moved in the front, back, up, down, left, and right directions through the operation of a joystick; a safety stop mechanism, which is set on the stand To prevent the stand from contacting the eye to be inspected; and a brake mechanism, which is arranged on the stand, and per...
