Abstract
Description
Technical Field
[0001] This utility model relates to the field of microscope imaging, and in particular to an imaging system. Background Technology
[0002] In ophthalmic surgeries for fundus diseases such as cataracts, glaucoma, and retinal diseases, ophthalmic surgical microscopes are generally used. Depending on the object being observed, ophthalmic surgical microscopes are divided into two types: anterior segment and posterior segment. Anterior segment ophthalmic surgical microscopes are generally used for imaging tissue surfaces.
[0003] During observation, it is usually necessary to refocus the lens to obtain different information about eye tissues. Existing ophthalmic surgical microscopes typically use focusing motors to achieve focusing. However, focusing motors have drawbacks such as slow response speed, which is not conducive to better observation during surgery. Utility Model Content
[0004] This invention provides an imaging system that can at least solve one of the problems mentioned in the background art.
[0005] An imaging system includes a camera, a motor focusing unit, and a liquid adjustment unit;
[0006] The motor focusing unit includes a motor and a camera mount. The camera is mounted on the camera mount, and the output end of the motor is connected to the camera mount.
[0007] Preferably, the motor is a voice coil motor.
[0008] Ideally, it also includes filters, beam splitters, and relay lens groups.
[0009] Preferably, it also includes a frame, on which the camera mount, motor, filter, beam splitter, and relay lens assembly are all mounted.
[0010] Preferably, a detachable filter holder is installed on the frame, and the filter is installed on the filter holder.

[0018] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0019] like Figures 1 to 3 As shown, an imaging system provided in this embodiment of the present invention includes a filter 6, a beam splitter 7, a relay lens group, a camera 2, a motor focusing unit, and a liquid adjustment unit 5.
[0020] The relay lens assembly is used to process the optical path and filter out short-wavelength light to focus it onto the objective lens for imaging.
[0021] The motor focusing unit includes a motor 3 and a camera mount 4. The camera 2 is mounted on the camera mount 4, and the output end of the motor 3 is connected to the camera mount 4. In this embodiment, the motor 3 is a voice coil motor, which can achieve minute adjustments.
[0022] The liquid adjustment unit 5 is the tube lens, located between the camera 2 and the filter 6;
[0023] This embodiment uses both motor-driven focusing and liquid-driven focusing units, ensuring faster response speed while also guaranteeing image quality.
[0024] It also includes a frame 1, a camera mount 4, a motor 3, a filter 6, a beam splitter 7, and a relay lens assembly, all of which are mounted on the frame 1.
[0025] A detachable filter holder 8 is installed on the frame 1, and the filter 6 is installed on the filter holder 8;
[0026] To enable fine adjustment of the position of the filter 6, a strip-shaped mounting groove 9 is provided on the frame 1, and a threaded hole corresponding to the strip-shaped mounting groove 9 is provided on the filter bracket 8. The bolt 10 passes through the strip-shaped mounting groove 9 and is fixed in the threaded hole. The length direction of the strip-shaped mounting groove 9 is parallel to the axial direction of the filter 6.
[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit and essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
