Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a binaural endoscope protective cover. Background Art

[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It can enter the stomach through the mouth or through other natural orifices into the body.

[0003] When an endoscope enters the human body for inspection, an endoscope protective cover is installed on the outside of the endoscope to prevent the patient's body fluids from contaminating and corroding the endoscope body. The setting of the endoscope protective cover can also effectively prevent the endoscope contaminated by the patient's body fluids from causing cross infection to the next patient. At present, traditional endoscope protective covers such as Figure 1 As shown, it includes a flat-bottom lens cover a, a sleeve b and a top end c. When in use, the endoscope is inserted from the top end c, so that the sleeve 2 fits with the side wall of the endoscope, and the lens of the endoscope fits with the flat-bottom lens cover a.

[0004] This conventional endoscope protective cover is only suitable for flat-bottomed endoscope lenses, but cannot fit closely to beveled lenses, resulting in a certain degree of distortion of the perspective light, thus causing perspective distortion; at the same time, the protective cover lacks a snap-on clamping device, and when in use, there is a risk of displacement of the protective cover, resulting in image instability. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a binaural endoscope protective cover to solve the problem that the endoscope protective cover in the prior art is suitable for a flat-bottomed endoscope head and is easily displaced during use, thereby affecting the perspective image effect.

[0011] In an embodiment of the present invention, the diameters of the first connector and the second connector are both smaller than the diameter of the soft sleeve.

[0012] Through the above technical solution, when in use, the soft sleeve is made of elastic material and fits tightly to the endoscope tube body, which increases the patient's comfort. The first connector and the second connector are connected to the soft sleeve to facilitate the replacement of the perspective lens end, thereby better adapting to different models of endoscopes.

[0013] In one embodiment of the present invention, the lens cover is a sloped lens cover, the cross section of which is trapezoidal and the longitudinal section is circular.

[0014] Through the above technical solution, the bevel lens cover is suitable for the bevel lens structure of the endoscope, so that it fits the endoscope more closely, eliminates perspective distortion, and makes the diagnosis and treatment results more accurate.

[0015] In one embodiment of the present invention, the lens cover is a horizontal lens cover, and its cross section is rectangular and its longitudinal section is circular.

[0016] Through the above technical solution, a conventional lens cover suitable for a horizontal lens cover is provided.

[0017] In one embodiment of the utility model, there are two snap grooves, which are symmetrically distributed on opposite sides of the inner wall of the snap joint, and each snap groove is provided with two snap strips, which are arranged at one end of the snap joint and located in the direction away from the recessed direction of the snap groove.

[0018] In one embodiment of the present invention, the diameter of the clamping joint is greater than the diameter of the first connector, and the opening joint further includes a connecting pipe disposed between the first connector and the clamping joint, and the connecting pipe is in the shape of a truncated cone.

[0019] As described above, the binaural endoscope protective cover of the utility model has the following beneficial effects:

[0020] The opening joint and the perspective lens end are connected to the soft sleeve, which makes it easy to replace different perspective lens ends and opening joints according to the model of the endoscope, so that the protective cover and the endoscope fit better. A bevel lens cover and a horizontal lens cover are set, which can be suitable for both flat-bottom endoscope lenses and bevel lenses, and has a wider range of usage scenarios.

[0021] On the other hand, a snap groove and a snap strip are provided at the opening joint to fix the protective cover on the oronasal nasal endoscope. The protective cover does not move during use, thereby ensuring image stability. At the same time, the protective cover can be removed from the oronasal nasal endoscope by simply twisting the bump to loosen the snap. The convenient installation and disassembly method greatly improves the work efficiency of medical staff. BRIEF DESCRIPTION OF THE DRAWINGS
