Description

Technical Field

[0001] The utility model relates to the technical field of hospital disinfection and isolation, in particular to a novel sterile cover for an operating microscope. Background Art

[0002] When doctors perform microsurgery (such as neurosurgery, ENT surgery, ophthalmology, microsurgery, etc.), they need to wrap the surgical microscope with a sterile cover to keep the microscope in a relatively sterile state. In the past, there have been many types of surgical microscope sterilization covers. There are so-called high, medium and low grades: the low-grade one is a large sterilized plastic bag, which requires the doctor to cut holes in the lens after putting on the sterilization cover and fix it. This kind of cover is easy to be contaminated during use, causing postoperative wound infection and delaying the doctor's operation time; the medium-grade one is designed with three sets of eyepiece-shaped sleeves at the front end of the bag, and a round hole is designed in the middle part of the bag. These parts are reserved for lens holes, and rubber bands are pre-set for easy fixation; the high-grade one is based on the medium-grade one, and the fixation of the eyepiece lens is changed to an easy-to-stick and easy-to-tear tape, and the fixation of the objective lens is changed to different fixed bayonet for different microscopes, and the pre-set of evacuating the air in the bag is added.

[0003] The problem with the above three types of sterile covers is that the three sets of eyepiece cover tubes are all at the front end, and the eyepieces of the surgical microscope are often in a face-to-face or triangular relationship during use. The relationship between the three sets of eyepiece cover tubes is difficult to handle during use, causing the sterile cover to twist and deform, affecting the surgical operation. In this regard, we proposed a new type of surgical microscope sterile cover. Utility Model Content

[0004] The utility model aims to provide a novel sterile cover for an operating microscope to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of surgical microscope sterile cover, comprising:

[0006] A sterile cover body, wherein the bottom end of the sterile cover body is arranged in a trapezoidal shape, three pairs of eyepiece lens covers are arranged on the sterile cover body, and the three pairs of eyepiece lens covers are respectively arranged at the top and two sides of the sterile cover body, an objective lens bonding seat is fixedly bonded to the middle of the front side wall of the sterile cover body, a double-sided adhesive is bonded to the inner wall of the objective lens bonding seat, plastic zippers are fixedly bonded to both side walls of the bottom end of the sterile cover body, a one-way ventilation valve is fixedly bonded to the rear side wall of the sterile cover body near the bottom end, and a connecting thread is provided on the one-way ventilation valve.

[0007] Preferably, a plurality of first straps are fixedly mounted on the objective lens bonding seat.

[0008] Preferably, a second strap is fixedly bonded to the rear side wall of the bottom end of the sterile cover body.

[0009] Preferably, the three pairs of eyepiece lens covers are all configured as trapezoidal cylinders.

[0010] Preferably, tear lines are provided at the front ends of the three pairs of eyepiece lens covers.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model provides a pair of eyepiece lens covers respectively arranged at the top and both sides of the sterile cover body, which can be well fitted with the microscope eyepieces when the sterile cover body is covered on the microscope, avoiding pulling of the microscope cover as a whole. The three pairs of eyepiece lens covers are all arranged in a trapezoidal cylindrical shape, and the front ends are all provided with tearing lines, so that when the eyepieces are inserted, the tension will gradually increase to achieve the effect of fixing the eyepieces, reducing the process of winding, binding and fixing;

[0013] 2. The one-way vent valve provided in the utility model can be used to draw the sterile cover body into a near-vacuum state with an air pump after the sterile cover body is installed, so that the sterile cover body and the microscope fit closely and are almost integrated, further reducing the chance of contamination. The objective lens bonding seat provided uses a self-adhesive tape as a temporary fixing medium. When installing the sterile cover body, the objective lens can be first glued to the sterile cover body and then the sterile cover body can be put on. This saves more effort, is simple to operate, and is not easy to contaminate the sterile cover body. BRIEF DESCRIPTION OF THE DRAWINGS
