Embodiment 1
[0050] refer to Figure 1 ~ Figure 4 , a light positioning device for an ultrasonic biological microscope, which includes at least one light source 3, which faces the direction of the transducer 21, and is used to locate the scanning area of the mark transducer 21; for controlling the switch of the light source 3 ;
[0051] Preferably, in this embodiment, the projection of the light emitted by the light source 3 on the eyeball is a strip of light; the light source 3 includes a housing for forming the projection, and the housing is provided with a slit 31 for letting out the light. The slit 31 is strip-shaped. Of course, the dot-shaped projection is also within the protection scope of the present invention, that is, the slit 31 is designed as a small circular hole; as long as the scattered light that can realize light positioning also falls within the protection scope of the present invention.
[0052] The strip projection formed by the light emitted by the light source 3 c...
Embodiment 2
[0064] This embodiment only describes the content that is different from the foregoing embodiments, and the same content will not be described again.
[0065] refer to Figure 5 ~ Figure 7 , a light positioning device for ultrasonic biological microscope, the light emitting source 3 is embedded in the bottom of the probe 2. refer to Figure 7 , In this embodiment, as a further improvement, the bottom of the probe 2 is provided with a transparent cover 35 , and the transparent cover 35 is located on the lower side of the light source 3 .
[0066] Because the eye cup needs to be used during the inspection, the transducer 21 at the lower end of the probe 2 needs to reciprocate in the eye cup, and at this time the distance between the edge of the eye cup and the bottom of the probe 2 is very small. At the bottom of the probe 2, it is easy to bump into the eyecup, affecting the hygienic conditions of the eyecup, and the light source 3 is not convenient for disinfection.

Embodiment 3
[0073] This embodiment only describes the content that is different from the foregoing embodiments, and the same content will not be described again.
[0074] refer to Figure 8 ~ Figure 11 , a light positioning device for an ultrasonic biological microscope, the light source 3 is provided with a slider A34, and the slider A34 is slidably connected to the first chute provided on the outer wall of the probe 2; the first chute is a damping chute.
[0075] In this embodiment, the light source 3 can slide on the peripheral outer wall of the probe 2, and since the first chute is a damping chute, the light source 3 can be fixed at any section of the first chute. It should be noted that the light source 3 is fixed on the top of the probe 2 to realize the function of convenient storage; in the actual use of UBM, the probe 2 will be held and moved, and the light source 3 is stored and fixed on the top of the probe 2. Convenient to hold and pinch the probe 2. When the light source 3 n...
