Abstract
Description
Technical Field
[0001] The embodiments of this utility model relate to an LED red light reflection device for biological and new pharmaceutical technologies, medical instrument technologies, equipment and medical software, and medical imaging technologies, and particularly to a zero-degree coaxial LED red light reflection device for an ophthalmic surgical microscope. Background Technology
[0002] In ophthalmic cataract surgery, the quality of red light reflection from the microscope is crucial for the surgeon. Currently, most microscopes achieve red light reflection through the dispersion of light from their own light source. For example... Figure 1 As shown, with an incident angle of approximately 6 degrees between the optical axes of the main focusing system 2 and the main beam, as well as commercially available microscopes, the main beam is incident at a 6-degree angle, while the secondary beam (reflected red light) is incident at a 2-degree angle. The reflected red light is partially separated from the main beam and reflected by mirror 3 at an incident angle of approximately 2 degrees before entering the eye. Due to the limited pupil diameter, most of the light with large incident angles is not reflected, resulting in a dim eye and hindering surgery. Theoretically, 0-degree incident red light provides the best reflection effect, but current main beam and red light reflection structures are relatively large. In ophthalmic surgical microscopes, due to limitations in structural space and field of view, it is difficult to replicate a 0-degree incident light structure using a single light source. Utility Model Content

[0005] Primary microscope;
[0006] The red light reflection optical axis is set on the preset axis of the microscope primary mirror;
[0007] The microscope objective is positioned below the primary microscope and along the red light reflection axis.
[0008] A miniature coaxial LED red light reflecting device is arranged between the microscope primary mirror and the microscope objective mirror, along the red light reflecting optical axis; so that the generated light is coaxially irradiated with the microscope primary mirror and the red light reflecting optical axis, thereby achieving coaxial red light reflection illumination.
[0009] Furthermore, in the zero-degree coaxial LED red light reflection device for ophthalmic surgical microscopes described in this utility model, the red light reflection optical axis is coaxial with the preset axis.
[0010] Furthermore, in the zero-degree coaxial LED red light reflection device for ophthalmic surgical microscopes described in this utility model, the red light reflection optical axis and the preset axis are set as the 0 axis.
[0011] Furthermore, in the zero-degree coaxial LED red light reflecting device for ophthalmic surgical microscopes described in this utility model, the miniature coaxial LED red light reflecting device further includes:
[0012] A heat dissipation module is disposed between the primary microscope mirror and the microscope objective lens;
[0013] The left optical axis of the microscope primary mirror is set on one side of the heat dissipation module;
[0014] The right optical axis of the microscope primary mirror is set on one side of the heat dissipation module;
[0015] A miniature LED module is disposed within the heat dissipation module;
[0016] A micro-focusing module is disposed below the micro-LED module and above the microscope objective.
[0017] Furthermore, in the zero-degree coaxial LED red light reflection device for ophthalmic surgical microscopes described in this utility model, the miniature LED module is electrically connected to the microscope through a drive module, and the microscope can independently control the operation of the miniature LED module; the miniature focusing module is mounted on the emitting end of the miniature LED module, and the heat dissipation module and the miniature LED module are placed coaxially on the optical axis of the microscope head; the light generated by the miniature LED module is coaxial with and coaxially illuminates the optical axis of the microscope, realizing zero-degree coaxial red light reflection illumination.
[0018] Furthermore, in the zero-degree coaxial LED red light reflection device for ophthalmic surgical microscopes described in this utility model, the left optical axis of the microscope primary mirror and the right optical axis of the microscope primary mirror are arranged perpendicular to the red light reflection optical axis.
[0019] Furthermore, in the zero-degree coaxial LED red light reflection device for ophthalmic surgical microscopes described in this utility model, the line connecting the center points of the left optical axis and the right optical axis of the primary microscope is perpendicular to the red light reflection optical axis.
[0020] Furthermore, in the zero-degree coaxial LED red light reflection device for ophthalmic surgical microscopes described in this utility model, the ophthalmic surgical microscope shines into the eyeball through a narrow pupil, and then the light inside the eyeball is reflected back along the original path to observe the inside of the eyeball.
[0021] Compared with the prior art, the embodiment of this utility model adopts a method of setting the red light reflection optical axis on the preset axis of the microscope main mirror; a microscope objective is set below the microscope main mirror along the red light reflection optical axis; and a miniature coaxial LED red light reflection device is set between the microscope main mirror and the microscope objective along the red light reflection optical axis. This ensures that the generated light is coaxially irradiated with the microscope main mirror and the red light reflection optical axis, achieving coaxial red light reflection illumination. It achieves a miniature design that can be embedded between the left and right optical axes of the main mirror; it has integrated microscope control; an independent light source; and zero-degree coaxial LED illumination light with high brightness and uniform light spot. This does not affect microscope observation and achieves sufficiently bright zero-degree coaxial incident angle LED illumination light, resulting in strong red light reflection. This device integrates control with the microscope, realizing the integrity of the microscope and improving its functionality. It solves the problem in the prior art where the main focusing system has an incident angle of approximately 6 degrees between its two optical axes, and traditional surgical microscopes and commercially available microscopes use a 6-degree incident angle for the main light and a 2-degree incident angle for the secondary light (red light reflection) into the eyeball. The reflected red light is partially separated from the main beam and reflected by mirror 3 at an angle of approximately 2 degrees before entering the eye. Due to the limited pupil diameter, most of the light with a large angle of incidence is not reflected, resulting in a dim eye and hindering surgery. Theoretically, red light reflection at 0 degrees of incidence is most effective, but current main beams and red light reflection structures are relatively large. In ophthalmic surgical microscopes, the limited space and field of view make it difficult to achieve the technical feasibility of creating a structure suitable for 0-degree incident light using a self-sourced light source.
