Description

TECHNICAL FIELD

[0001] The utility model relates to ophthalmic microscope accessory technical field especially, relate to a kind of ophthalmic microscope head cleaner. BACKGROUND

[0002] Ophthalmic microscope is the auxiliary equipment of vital importance in surgery, and the cleanliness of its lens directly relates to the quality of intraoperative imaging, and then affects the accuracy and safety of surgical operation. However, the lens of microscope is often contaminated by dust, oil stains, water droplets and other pollutants in the surgical environment during use, which affects the imaging clarity. Therefore, the cleaning of microscope lens becomes an important link that must be solved in the surgical process.

[0003] Ophthalmic microscope is mostly a precision optical component, and its surface is plated with high-precision optical coating, which is difficult to withstand the high temperature, high pressure or chemical cleaning agent erosion that may occur during machine washing. Therefore, conventional cleaning agents cannot be used for cleaning the lens of microscope. Currently, the cleaning of microscope lens mainly relies on manual operation, including wiping, brushing and blowing. These traditional methods have certain effects on cleaning the lens of microscope, but also have many limitations.

[0004] (1) Manual wiping

[0005] Manual wiping of the lens surface with flexible lens cloth or special cleaning materials is the most commonly used cleaning method. This method has certain cleaning effect on light dust or fingerprint and other pollutants, but the cleaning efficiency and effect largely depend on the proficiency and patience of the operator. Since manual wiping requires direct contact with the lens surface, improper operation may cause scratches or cleaning marks on the lens. In addition, it is not practical to frequently pause the operation for manual wiping during the operation.

[0006] (2) Brush cleaning

[0007] Flexible brush is used to clean the lens surface, which is another traditional cleaning method. This method cleans the dust or loose particles attached to the surface through the contact between the bristles and the lens. However, due to the limited flexibility of the bristles, the cleaning effect on oil stains and liquid stains is poor, and improper use may cause scratches on the lens. In addition, it is difficult to cover the edges or recessed areas of the lens when cleaning with a brush, and the cleaning effect is often not comprehensive enough.

[0008] (3) Ear bulb blowing

[0009] The ear cleaning ball is a common auxiliary cleaning tool, which uses air flow to blow away the dust or particles on the lens surface. This method is simple to operate and does not contact the lens surface, so there is no risk of scratching the lens. However, the blowing method can only remove loose particles and has poor effect on tightly adhered contaminants such as oil stains or liquid marks. Especially in high humidity or liquid environment, blowing with an ear cleaning ball may not be able to remove water marks, and even spread the pollution, further polluting the microscope lens.

[0010] In summary, these traditional cleaning methods have certain deficiencies in actual use, and cannot fully meet the needs of efficient, safe and real-time cleaning of ophthalmic microscope lenses. Therefore, it is expected to develop a microscope lens wiping device that can overcome the defects of the above methods, which is a technical problem to be solved at present. Such a device needs to realize the instant cleaning of the microscope lens without affecting the continuity of the operation, so as to ensure the continuous clarity of the lens imaging and provide more reliable protection for ophthalmic surgery.

[0034] Referring to Figures 1 to 5 The embodiment provides an ophthalmic microscope head cleaner. The ophthalmic microscope head includes a lens barrel 7 and at least one convex lens 8 embedded in the lens barrel 7. The ophthalmic microscope head cleaner includes:

[0035] The barrel 1 is divided into an upwardly open upper accommodating groove 11 and a downwardly open lower accommodating groove 12 by a partition plate.
