Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a protective cover for a surgical microscope. Background Art

[0002] In various industrial fields, special protective work requires wearing special protective covers, and people are increasingly paying attention to their own protection. In a relatively enclosed environment, long-term exposure to high-concentration aerosols may lead to aerosol transmission. Doctors and medical staff are at high risk of occupational exposure due to the particularity of their working environment. For example, when a dentist treats a patient's oral cavity, the patient's oral cavity is in an open state, inevitably contacting splashed blood, water vapor formed by breath, tooth debris, etc., which easily leads to contact infections, making the aerosol exposure risk for dentists and medical staff greater. Similarly, doctors using surgical microscopes also face huge infection risks.

[0003] Currently, most doctors use masks to treat patients, which is extremely risky and not very safe and reliable. Some doctors use helmet-type face masks, but wearing them for a long time is very uncomfortable, and moreover, they cannot adjust the interpupillary distance to suit different doctors. In the prior art, a conical protective film was also installed and removed under the large zoom objective lens of the surgical microscope to block as close to the source of transmission as possible, but the use effect was not very good, the installation and removal were not very convenient, and it would also affect the operability of the doctor. In addition, the protective covers on the market are all two-dimensional planar structures, with small sizes and unable to provide large-area protection. In summary, in order to effectively protect the occupational safety of surgical medical staff, it is particularly necessary to develop a suitable protective cover to avoid aerosol and contact infections. Summary of the Invention

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] As shown in the figure, a protective cover for a surgical microscope includes a first protective cover 1 and a second protective cover 2, where:

[0035] As Figure 1 , 2 shown: The first protective cover 1 includes a cover main body 10. The cover main body 10 is provided with a first hole 100 and a second hole 101. The shape of the first hole 100 matches the shape of the eyepiece, and the shape of the second hole 101 allows the eyepiece to move in the left-right direction after being inserted. The illustrated first hole 100 and second hole 101 are respectively located on the left and right sides. In this embodiment: The first hole 100 of the first protective cover 1 is a circular hole, and the second hole 101 of the first protective cover 1 is a strip-shaped hole extending in the left-right direction, such as an oval.

[0036] The first protective cover 1 further includes first side wings 11 connected to the left and right sides of the cover main body 10 and second side wings 12 connected to the upper and lower sides of the cover main body 10, where: The first side wings 11 and the second side wings 12 are bent towards one side of the cover main body 10. The cover main body 10, the first side wings 11, and the second side wings 12 of the entire first protective cover 1 are integrally formed. By setting the side wings at a unique angle, a barrier with a larger surface area is provided while still allowing convenient access to the control knobs and the scale lines on the machine itself.

[0037] In this embodiment: The entire first protective cover 1 expands to 480x400x0.5 mm. The bending angle of the first side wing 11 relative to the cover main body 10 is 90 degrees, and the width is 100 mm. The bending angle of the second side wing 12 relative to the cover main body 10 is 60 degrees, and the width is 100 mm. The specific dimensions of the first protective cover 1 can be adjusted according to actual needs.

[0038] As Figure 3 , 4As shown in the figure: The second protective cover 2 is provided with a third hole 20 and a fourth hole 21. The shape of the third hole 20 matches the shape of the eyepiece, and the shape of the fourth hole 21 allows the eyepiece to move in the left-right direction after being inserted. The illustrated third hole 20 and fourth hole 21 are respectively located on the right and left sides. In this embodiment: The third hole 20 of the second protective cover 2 is a circular hole, and the fourth hole 21 of the second protective cover 2 is a strip-shaped hole extending in the left-right direction, such as an ellipse. The sizes of the circular holes of the first hole 100 of the first protective cover 1 and the third hole 20 of the second protective cover 2 are the same, and the sizes of the elliptical holes of the second hole 101 of the first protective cover 1 and the fourth hole 21 of the second protective cover 2 are the same. The size of the second protective cover 2 is smaller than the size of the cover body 10 of the first protective cover 1. In this embodiment: An elliptical sheet is used, and only the third hole 20 and the fourth hole 21 are allowed to be opened in terms of size.

[0039] In addition, the first protective cover 1 and the second protective cover 2 are made of transparent plastics such as PC, and an anti-fog layer is coated on the surface, with good transparency, avoiding fogging, and having no scratches on the surface. The first protective cover 1 and the second protective cover 2 have rigid capabilities, are moderately hard and soft, can always maintain the best position for shielding, and the clear material allows the surgical microscope buttons / controls to be visualized.

[0040] As Figure 5 , 6 As shown in the figure: When in use, first put the first hole 100 of the first protective cover 1 on the left eyepiece, and the second hole 101 on the right eyepiece. Then put the third hole 20 of the second protective cover 2 on the right eyepiece, and the fourth hole 21 on the left eyepiece. Since the interpupillary distance needs to be adjusted between 55mm - 70mm, through the circular holes and elliptical holes on the first protective cover 1 and the second protective cover, they are used to be staggered and installed on the two eyepiece tubes, which is convenient for doctors to adjust, so as to make changes according to the interpupillary distances of different doctors and be applicable to different interpupillary distances.

[0041] The protective cover of this embodiment can completely cover the human face, thus improving the safety of doctors during medical treatment. The specifications and extended lengths are the best sizes summarized through doctors' tests. In this way, doctors only need to stagger and install the protective screen on the binocular eyepiece tube, and the extended lengths on the four sides are just enough to cover the four sides of the face. This is better than just wearing a mask, expanding the shielding area and effectively ensuring the protection of doctors. The protective cover can block splashed pollutants, does not interfere with surgical operations, is safe and reliable, can be used as a disposable item, and if there are touch marks, it can be wiped with clean water or alcohol on the surface with a non-gauze and wait for it to volatilize naturally.

[0042] This product can not only be applied during the epidemic, but also after the epidemic, reminding practitioners to strengthen occupational protection in the future and become a normal protective tool.

[0043] The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It is not intended to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
