Strabismus nine-direction photographic instrument

Abstract

The invention provides a strabismus nine-direction photographic instrument. The strabismus nine-direction photographic instrument comprises a chassis, wherein driving wheels are arranged at the bottomof the chassis; a lifting structure which ascends and descends in the vertical direction is arranged at the top of the chassis, and the chassis is connected with a nine-direction structure through the lifting structure; the nine-square structure comprises a bottom box; the bottom box is installed on the lifting structure; a nine-grid light-transmitting window is formed in one vertical side face of the bottom box, and the bottom box slides to the nine-grid position of the nine-grid light-transmitting window through a first sliding assembly and a second sliding assembly; a sliding rod is arranged on the side face, back to the nine-grid light-transmitting window, of the sliding block; a lamp and a miniature camera are installed on the side face right facing the nine-grid light-transmitting window and are connected with a first controller, and the first controller is further connected with a first power module and a first wireless signal receiving and transmitting module; and the second sliding assembly and the first sliding assembly are the same in structure, and sliding motors of the second sliding assembly and the first sliding assembly are connected with a second controller. According to the strabismus nine-direction photographic instrument, the distance of 33cm required by strabismus detection can be accurately determined, and the obtained nine-azimuth map is more accurate.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a squint nine-direction camera. Background technique [0002] Strabismus means that both eyes cannot fixate on the target at the same time. It is a common disease in ophthalmology. Accurate degree of strabismus is an important factor affecting the therapeutic effect. At present, the commonly used methods for measuring strabismus include: prism plus cover detection method, corneal light reflection method, etc. During the inspection process, the patient's eyes need to be photographed at a position 33cm away from the patient to obtain a nine-direction map, and the patient's strabismus can be known by analyzing the nine-direction map. At present, strabismus detection lacks a dedicated instrument to obtain the nine-direction map, which makes the entire detection process time-consuming and inaccurate. Moreover, when obtaining the nine-direction map, it needs to be obtained at a d...

Problems solved by technology

At present, strabismus detection lacks a special instrument to obtain the nine-direction map, which makes the whole detection process time-consuming and inaccurate. Furthermore, when obtaining the nine-direction map, it needs to be obtained at a distance of 33cm from the human face. At present, the The distance is not accurately obtained, that is, the camera lens is easy to change during the shooting process when obtaining the nine-direction map, so that there is a certain error in the obtained image, which affects the accuracy of strabismus detection; in addition, in order to ensure the accuracy of detection, the It can only be realized with the assistance of doctors and assistants, which makes the whole detection process more troublesome, labor-intensive, and time-consuming
