Abstract

The invention provides a tilt-shift fault scanning device, which is characterized by comprising a rotary scanning part, wherein the rotary scanning part is arranged on a base part and comprises a rotary seat; both ends of the rotary seat are respectively provided with a driven synchronous belt wheel and a rotary circular disc; the rotary circular disc is respectively provided with crack illuminating light path equipment, crack projection light path equipment, focusing light path equipment and tilt-shift shooting light path equipment; the base part comprises a bracket; the rotary scanning partis arranged at the top of the bracket; a motor is arranged at the bottom of the bracket; a drive synchronous belt wheel is arranged on an output shaft of the motor; and the drive synchronous belt wheel and the driven synchronous belt wheel are connected by using the synchronous belt. The invention has the advantages of realizing overall shooting of the eyes of the patient, eliminating the transparent deformation, having high collecting speed, fully ensuring the health of the patient, and prolonging the service life.

Description

technical field [0001] The invention relates to an ophthalmological diagnostic device, which is mainly used for examining the front part of the eye, including cornea, iris, crystal and other tissue structures, and relates to the comprehensive application of the formation principle of narrow slit light, visible light tomography and axis-shifting photography technology. Background technique [0002] Traditional anterior segment inspection instruments such as: slit lamp microscope, keratometer, A / B ultrasound, corneal pachymeter, and corneal topograph have certain limitations due to the limitation of imaging principle, single inspection function or inability to quantify measurement data. sex. Moreover, the inspection instruments of the anterior segment currently used in China are all imported from abroad, and the purchase cost is quite high. For some small hospitals, they cannot afford such a high cost, which makes it difficult to diagnose the disease. [0003] In US Patent No...
