Description

1. Technical field

[0001] The invention relates to a B-type ultrasonic electromagnetic mechanical fan scanning device, which is used for B-type ultrasonic scanning diagnosis in ophthalmology and belongs to the technical field of medical equipment. 2. Background technology

[0002] The mechanical sector scanning device can be used for B-mode ultrasonic differential diagnosis of intraocular and orbital diseases, such as retinal detachment, intraocular and orbital tumors, vitreous opacity, hemorrhage, fundus lesions and intraocular foreign bodies and other diseases. Because of its low cost, high scanning frequency (about 10Hz), and high cost performance, it is widely used in B-mode ultrasonic diagnostic instruments for intraocular and orbital diseases, and has broad application prospects.

[0003] However, traditional link-type mechanical sector scanning devices are all based on the time method, that is, a single ultrasonic scanning process is triggered at a uniform time interv...
