Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an ophthalmic surgical medical device. Background Technology

[0002] The ophthalmic surgical observation illumination magnifying glass is a type of ophthalmic surgical medical instrument. It focuses the observer's binocular vision into a narrow cavity, producing a bright and magnified three-dimensional field of view, providing a unique three-dimensional and in-depth image for examination and treatment, and has a good usage effect.

[0003] Existing ophthalmic surgical observation magnifying glasses cannot be adjusted in height and angle, making them inconvenient to use. Furthermore, the fixed distance between the two magnifying glasses means that different doctors may not be able to match the distance between their eyes, making it difficult to achieve good visual results. In addition, prolonged use can easily cause eye strain. Therefore, a new ophthalmic surgical medical device is proposed. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, one objective of this utility model is to provide an ophthalmic surgical medical device that can increase ease of use and allow the distance between the two cylindrical magnifying glasses to be adjusted automatically, thereby achieving good visual effects and improving user comfort.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ophthalmic surgical medical device, comprising a headband, an arc-shaped plate fixedly connected to the outside of the headband, two fixed blocks fixedly connected to the outside of the arc-shaped plate, a rotating shaft rotatably connected inside the two fixed blocks, a platform plate fixedly connected to the outside of the rotating shaft, an extension block fixedly connected to the bottom of the platform plate, two threaded rods fixedly connected inside the extension block, a movable block slidably connected to the outside of each of the two threaded rods, a second fastening nut and a third fastening nut respectively threadedly connected to the outside of the threaded rods on both sides of the movable block, a connecting rod fixedly connected to the bottom of the movable block, a cylindrical magnifying glass installed at the bottom of the connecting rod, and a lighting lamp installed at the bottom of the platform plate.

[0007] Preferably, a nose clip is fixedly connected to the bottom of the arc-shaped plate.

[0008] Preferably, a sponge pad is adhered to the outside of the arc-shaped plate.

[0009] Preferably, the external threaded connection of the shaft has two first fastening nuts.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention allows the rotating shaft and platform plate to be adjusted at an angle by setting a first fastening nut, thereby adjusting the height of the cylindrical magnifying glass. By rotating the second and third fastening nuts, the limit on the moving block can be released, thereby realizing the angle adjustment of the cylindrical magnifying glass, which increases the convenience of use, and allows the distance between the two cylindrical magnifying glasses to be adjusted by itself, which can obtain a good visual effect and thus improve the comfort of use.
