Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an ultrasonic biomicroscope detection device for ophthalmology and a use method thereof. Background Art

[0002] Phakic posterior chamber intraocular lens (ICL) implantation is one of the main refractive surgeries in the world. Vault height (the distance between the ICL and the anterior surface of the natural lens) is an important indicator for evaluating the safety of ICL surgery. ICL is available in a variety of sizes, such as 12.1mm, 12.6mm, 13.2mm, and 13.7mm. The size of the ICL, the distance from the ciliary sulcus to the ciliary sulcus (STS), the morphology of the ciliary sulcus, ciliary body cysts, the morphology of the iris, and the sagittal height of the lens are factors that affect the postoperative vault height and are of great significance to surgical design.

[0003] Due to the obstruction of light by the iris, the distance from ciliary sulcus to ciliary sulcus (STS), the morphology of the ciliary sulcus, and ciliary body cysts are usually detected by ultrasound biomicroscopy (UBM). Ultrasound biomicroscopy (UBM) can obtain high-definition images of the iris, lens, ciliary sulcus, and suspensory ligament.

[0004] At present, ultrasound biomicroscopy (UBM) usually relies on the operator's experience to obtain static images by placing a handheld probe on the ocular structure. However, the human eye has 70 to 80 ciliary processes, and there are gaps between the ciliary processes. Small movements of the probe have a significant impact on the image. Therefore, whether the static image obtained by the handheld probe can accurately reflect the true morphology of the ciliary sulcus is highly dependent on the operator's skills, has a certain degree of subjectivity, and has low reproducibility between different operators. In addition, the shape of ciliary body cysts is spherical and occupies a certain volume, and static images are difficult to reflect their true size. Summary of the invention

[0013] Furthermore, the parameters of the motion controller are set to 144,000 pulses per rotation and 8,000 pulses per second.

[0014] Further, adjusting the cantilever position so that the probe is aligned with the eye structure comprises the following steps: Adjust the cantilever height so that the probe is perpendicular to the eye structure; Adjust the horizontal position of the cantilever so that the probe is aligned with one end of the eye structure in the horizontal direction.

[0015] Furthermore, the method of use further comprises the following steps: Fix the data cable connecting the probe and the host on the cantilever with a cable tie.
