Technical Field

The utility model belongs to the technical field of ophthalmic medical instrument, especially, relate to a light positioner and supersound biomicroscope for supersound biomicroscope.

Background

An Ultrasonic Biomicroscope (UBM) is a novel ophthalmological B-mode ultrasonography inspection apparatus developed in the early 90 s of the 20 th century. The UBM utilizes a programmable logic device to control an electronic circuit to excite a high-frequency ultrasonic sensor to emit high-frequency ultrasonic waves serving as a signal source, receive ultrasonic echo signals and perform electronic signal processing to obtain digital images related to examined tissues, and provides a low-power optical microscope effect and anterior segment two-dimensional images with different sections for people by combining a computer image processing technology. UBM has the characteristics of high resolution, real-time performance, quantification, no influence by turbid cornea and crystalline lens and the like, and is widely applied in clinical ophthalmology.

when the ultrasonic biomicroscope inspects the eyes of a patient, the scanning path of the transducer on the probe is in a straight line, and the scanning area of the probe is in a slice shape, namely the projection of the scanning path of the transducer on the surface of an eyeball and a plane area extending to the deep part of the eyeball; after scanning, the ultrasonic biomicroscope can obtain a digital image of the eye, which is used as a diagnosis basis for the disease condition of the affected eye. However, the conventional ultrasound biomicroscope emits ultrasound scanning, and ultrasonic waves are a high-frequency sound wave which cannot be seen, so that when the UBM scans the eyeball, a sectional view of the eye can be displayed on a display, but a focus position cannot be accurately marked on the eyeball, a specific point position of examination scanning cannot be directly and clearly reflected, an operator makes a judgment only by self-sense or experience, and errors easily occur, and diagnosis and treatment are not facilitated.

For example, the focus is located in the 6-point position direction of the affected eye, when an operator scans by using the UBM, the UBM has no positioning mark on the surface of the eyeball, the operator does not know what region of the affected eye is scanned by himself or herself, and in order to avoid missed diagnosis and misdiagnosis, the affected eye is preferably scanned from one end to the other end of the affected eye, and the carpet type scanning mode has extremely low working efficiency; even if the scanning is correct, the focus is displayed on the UBM display, but a positioning mark can not be made on the surface of the eyeball, and image data can not be stored, so that the specific position of the focus of the affected eye and the range of the focus of the affected eye in the eyeball are difficult to directly judge after the examination, and the affected eye needs to be reexamined and confirmed by using the ultrasonic biomicroscope, thereby causing the physiological pain of a patient, increasing the workload of a doctor, increasing the medical cost and causing the waste of medical resources.
