Technical Field

[0001] This utility model mainly relates to the field of medical equipment, and in particular to a prefabricated binocular surgical magnifier. Background Technology

[0002] Existing surgical magnifying glasses require specialized drilling equipment to drill holes in the optical lenses before bonding them with UV adhesive. This process demands highly skilled professionals, involves lengthy training, and results in a low yield rate. The selection of optical lenses is also stringent; lenses with excessively efflorescent coatings cannot be used, as they can compromise the bonding strength between the lens and the endoscope barrel.

[0029] The preferred mechanism and method of motion implementation of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 8 As shown, this utility model provides a prefabricated binocular surgical magnifying lens, comprising: a fixing frame 1, the fixing frame 1 being generally π-shaped, including a crossbeam 2 for mounting optical lenses and extension portions 14 extending outward from both ends of the crossbeam 2; the fixing frame 1 also includes two fixing rings 3 located at the other end of the extension portions 14 for mounting a magnifying lens barrel 6, the fixing rings 3 being connected to the crossbeam 2 via the extension portions 14 and extending to a position close to the wearer's interpupillary distance. Figure 4 As shown, the central axis of the fixing ring 3 forms an inward angle with the longitudinal axis of the crossbeam 2, namely, the visual axis angle. This visual axis angle varies depending on the interpupillary distance and working distance. Based on commonly used working distances such as 300mm, 400mm, 450mm, 500mm, 550mm, and 600mm, and considering the different interpupillary distances of users, this helps users with the same interpupillary distance to achieve the effect of binocular image overlap and fusion within a set working distance. The crossbeam 2 can be made of metal, resin, or other materials, and has a nose pad 4. The crossbeam 2 has several fixing holes for fixing the temples or optical lenses 5 using screws or clips.

[0031] The assembled binocular surgical magnifying mirror also includes a magnifying lens tube 6 detachably connected to the fixing ring 3. In this embodiment, the front end face of the magnifying lens tube 6 is a magnifying lens 7, and the outer side of its rear housing is preferably provided with a second thread 8 that mates with a first thread provided on the fixing ring 3, so that the magnifying lens tube 6 can be detachably installed on the fixing frame 1 by means of threaded connection. The first thread and the second thread 6 can be internal threads and external threads, respectively; or, the first thread and the second thread 8 can be external threads and internal threads, respectively. Alternatively, the magnifying lens tube 6 can be connected to the fixing frame 1 by means of snap-fit ​​or other methods. The rear housing of the magnifying lens tube 6 has a mounting portion 9. The mounting portion 9 is a groove-shaped portion formed by extending a portion of the housing of the magnifying lens tube 6 rearward to form a accommodating part.

[0032] The corrective lens ring 10 is detachably mounted to the assembly part 9 at the rear end of the magnifying lens barrel 6. The corrective lens ring 10 is used to mount either a myopia lens 12 or a presbyopia lens 11, and the corrective lens ring 10 is configured with the appropriate specifications according to the myopia lens 12 or the presbyopia lens 11. The corrective lens ring 10 is provided with a sealing ring groove. A sealing ring is used to seal the corrective lens ring 10 to the assembly part 9 at the rear end of the magnifying lens barrel 6, and the corrective lens ring 10 is detachably mounted to the assembly part 9 by squeezing the sealing ring 13. At least two sealing ring grooves may be provided, one corresponding to the myopia lens sealing ring 23 for the myopia lens and the other to the presbyopia lens sealing ring 24 for the presbyopia lens. Because the myopia lens is thinner, the myopia lens sealing ring groove 23 is located closer to the outside, while the presbyopia lens is thicker, so the presbyopia lens sealing ring groove 24 is located closer to the inside. Thus, the corrective lens ring is fixed by the two sealing ring grooves. The myopia lens 12 or presbyopia lens 11 can be conveniently fitted for eye exams based on the shape of the corrective lens ring 10 or a mold. It can be fixed to the corrective lens ring 10 by compression or with UV adhesive. If replacement is needed, the corrective lens ring 10 can be replaced or the lens can be removed. Therefore, according to the wearer's actual needs, the interaction between the first and second threads 8 allows for arbitrary assembly and switching of different magnifications of the lens barrel at the same working distance. The corrective lens ring 10 also has a hole 25 for easy rotation to adjust the lens axis.

[0033] The structure of the assembled fixture 1 and magnifying lens tube 6 is as follows: Figure 4 and Figure 5As shown, D2 represents the interpupillary distance, and D1 represents the working distance focusing angle of the magnifying lens tube 6. Furthermore, the fixing ring 3 is tilted relative to the extension 14 towards the wearer's body, forming an obtuse angle α between the outer surface of the fixing ring 3 and the extension 14. This tilt angle α ensures that the wearer can observe in a more relaxed posture, thus performing surgeries and other tasks, and preventing excessive neck strain from bending over.

[0034] The assembled binocular surgical magnifying glass may further include a wearing structure, which can be a framed or rimless structure with temples. When the wearing structure is rimless, the temples 15 are fixed by pre-installed fixing holes on the optical lenses 5 and screws or clips. When the wearing structure is framed, the eyeglass frame 16 extends from the fixing frame 1 to both sides, or it can be understood that the eyeglass frame 16 is part of the fixing frame 1, and the temples 17 are disposed on the eyeglass frame 16.

[0035] The wearing structure can also be a headband, which includes a headband 22, a damping movable bracket 18, and a clamp 19. The headband 22 is a wearable part composed of elastic bands, with a rigid support portion at the edge where it fits over the head. The damping movable bracket 18 is mounted on the support portion. The damping movable bracket 18 is fixed to the headband 22 and has three or more movable points to facilitate adjustment of the overall position of the fixing frame 1. The clamp 19 is located at the end of the damping movable bracket 18 and can be installed onto the fixing holes of the crossbeam 2 by screws or clips, thus enabling the fixing frame 1 to be detachably fixed by the clamp 19. The headlamp 20 is fixed to the damping movable bracket 18 or the fixing frame 1, located between the two optical lenses 5. The headlamp 20 can be fixed to the knob 21 of the clamp 19 by the headlamp clamp.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
