Description

Technical Field

[0001] The utility model relates to the technical field of surgical microscopes, in particular to a disposable lens cover for a surgical microscope. Background Art

[0002] Surgical microscopes are widely used in neurosurgery, orthopedics, ophthalmology, otolaryngology and other specialized surgeries for dissection, suturing of microvessels and nerves, and other delicate surgeries or examinations that require the aid of a microscope. At the same time, the video recording and broadcasting system of the surgical microscope has the function of saving video recordings of the surgical process, making it convenient to review and archive previous cases.

[0003] During the use of surgical microscopes, the operating room needs a sterile environment. In order to prevent the microscope lens from being contaminated, a microscope lens cover is needed to protect the microscope lens. Existing surgical microscope lens covers are of two types: reusable sterilizable lens covers and disposable lens covers. Reusable sterilizable lens covers need to be sterilized after surgery for next use, but the sterilization cost is high, which increases the cost of use; disposable microscope lens covers are directly discarded as medical waste after use, which is cheaper than reusable sterilized lens covers; therefore, disposable lens covers are currently used more often;

[0004] The existing lens cover includes a lens cover body and a fixing seat located on the upper part of the lens cover, that is, the fixing seat needs to be fixed on the lens first, and then the lens cover body is inserted and fixed on the fixing seat, which is relatively complicated to operate;

[0005] Each type of surgical microscope needs to be equipped with a lens cover of a corresponding size. This is because the lens lengths of different types of surgical microscopes are different. Since the lens cover body and the fixing seat are fixed by a plug-in type, the depth of the fixing seat directly determines the adaptable lens length. However, the depth of the fixing seat is usually small, resulting in poor adaptability.

[0006] Therefore, a disposable lens cover for an operating microscope is needed to overcome the above-mentioned problems. Utility Model Content

[0007] In order to solve the above problems, an embodiment of the utility model provides a disposable lens cover for a surgical microscope. The lens cover body is integrally formed, that is, the traditional fixing seat and the lens cover body are combined together. The lens cover body can be directly installed on the lens, which is relatively convenient to install, thereby achieving the purpose of solving the problems raised in the background technology.

[0008] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a disposable lens cover for a surgical microscope, comprising an integrally formed lens cover body, the outside of the lens cover body is fixedly connected to a fixing plate, and the fixing plate is connected to a strap; an extension ring is threadedly connected to the opening of the lens cover body.

[0009] As a further improvement of the above technical solution:

[0010] The exterior of the extension ring is provided with anti-slip protrusions.

[0011] The binding strap is fixedly connected with a Velcro.

[0012] The lens cover body is composed of a sleeve portion and an observation portion, and the observation portion is arranged obliquely.

[0013] A protective film is provided on one side of the observation portion.

[0014] The beneficial effects of the embodiments of the utility model are:

[0015] The lens cover body in this application is made by integrating the traditional fixing seat and the lens cover body. The lens cover body in this application can be directly installed on the lens without installing the fixing seat first and then inserting the lens cover body. That is, the integrated design simplifies the operation and facilitates use; and avoids the lens cover body slipping off the fixing seat during surgery to cause contamination of the surgical site;

[0016] At the same time, since the lens cover body and the fixing seat are set as an integrated structure in the present application, the internal depth is increased, thereby increasing the length range of the lens that can be adapted thereto;

[0017] When in use, the depth of the interior of the lens cover body can be further expanded by rotating the extension ring, thereby further increasing the length range of the lens that can be adapted thereto. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0024] See also Figures 1 to 4 The embodiment of the utility model discloses a disposable lens cover for a surgical microscope, comprising an integrally formed lens cover body 1, a fixing plate 3 is fixedly connected to the outside of the lens cover body 1, and a strap 4 is connected to the fixing plate 3; when the lens cover body 1 is installed on the lens, the lens cover body 1 is firstly covered on the outside of the lens, and then fixed by the strap 4, and the installation is completed;

[0025] An extension ring 2 is threadedly connected to the opening of the lens cover body 1;

[0026] The lens cover body 1 in the present application is made by integrating the conventional fixing seat and the lens cover body. The lens cover body 1 in the present application can be directly installed on the lens without installing the fixing seat first and then inserting the lens cover body. That is, the integrated design simplifies the operation and facilitates use; and avoids the contamination of the surgical site caused by the lens cover body slipping off the fixing seat during surgery;
