DETAILED DESCRIPTION OF THE EXECUTION FORMS

[0016] The following section, with reference to the accompanying drawings and using specific embodiments, discusses preferred mechanisms and methods for realizing a movement according to the present invention.

[0017] As in Fig. As shown in Figures 1 to 8, the present invention provides a mountable surgical binocular loupe. It comprises a mounting frame 1, which is essentially π-shaped and includes a crossbar 2 for mounting optical lenses, and extension sections 14 located at both ends of the crossbar 2 and extending outwards. The mounting frame 1 further includes two mounting rings 3 located at the other end of the respective extension sections 14 and provided for mounting lens sleeves 6. The mounting rings 3 are connected to the crossbar 2 via the respective extension sections 14 and extend to positions whose distance from each other corresponds to the interpupillary distance of the user. As shown in Figures 1 to 8, the mounting frames 14 are arranged in a 3-point configuration. Fig. As shown in Figure 4, the central axis of the respective mounting ring 3 and the longitudinal axis of the crossbar 2 form an inwardly directed angle, namely the visual axis angle or convergence angle. This visual axis angle varies depending on the interpupillary distance and working distance. Based on common working distances such as 300 mm, 400 mm, 450 mm, 500 mm, 550 mm, and 600 mm, etc., and the different interpupillary distances of users, this allows users with the same interpupillary distance to achieve the effect of binocular image overlap and fusion within the set working distance. The crossbar 2 can be made of metal, resin, or other materials and is equipped with a nose pad 4. The crossbar 2 itself has several mounting openings that serve to fix spectacle temples or optical lenses 5 using screws or snap fasteners.

[0018] The mountable surgical binocular magnifier further comprises a magnifying sleeve 6 detachably connected to the respective mounting ring 3. In the present embodiment, a front end face of the magnifying sleeve 6 is designed as a magnifying lens 7, while its housing is preferably provided with a second thread 8 on the outside at the rear end region, which interacts with a first thread on the respective mounting ring 3. This allows the magnifying sleeve 6 to be detachably mounted to the mounting frame 1 by means of a threaded connection. The first thread and the second thread 8 can each be designed as internal and external threads, respectively, or the first and second thread 8 can each be designed as external and internal threads, respectively. Alternatively, the magnifying sleeve 6 can also be connected to the mounting frame 1 by means of a snap-fit ​​connection or other methods. The housing at the rear end region of the magnifying sleeve 6 has a mounting section 9.The assembly section 9 is created by a part of the housing of the magnifying sleeve 6 extending to the rear, thus forming a receiving groove-shaped section.

[0019] A corrective lens ring 10 is detachably mounted on the mounting section 9 of the rear end region of the magnifying sleeve 6. The corrective lens ring 10 serves to accommodate a lens for myopia 12 or a lens for presbyopia 11, the corresponding corrective lens ring 10 being configured in a suitable version depending on whether it is a lens for myopia 12 or a lens for presbyopia 11. A sealing ring groove is provided on the corrective lens ring 10, and the corrective lens ring 10 and the mounting section 9 of the magnifying sleeve 6 are sealed against each other by a sealing ring, the corrective lens ring being detachably mounted on the mounting section 9 of the rear end region of the magnifying sleeve 6 by compressing the sealing ring 13.At least two sealing ring grooves can be provided: one sealing ring groove 23 for a myopic lens, corresponding to the corrective lens ring for a myopic lens, and one sealing ring groove 24 for a presbyopia lens, corresponding to the corrective lens ring for a presbyopia lens. Since a myopic lens has a thinner lens body, the sealing ring groove 23 for a myopic lens is positioned closer to the outer surface, while, due to the greater thickness of a presbyopia lens, the sealing ring groove 24 for a presbyopia lens is positioned closer to the inner surface. In this way, the corrective lens ring is secured by the two sealing ring grooves.The lens for myopia 12 or the lens for presbyopia 11 can be easily configured according to the shape of the corrective lens ring 10 or using a template, based on an optometric examination. Attachment to the corrective lens ring 10 can be achieved either by press fit or with UV adhesive. If a replacement is necessary, either the entire corrective lens ring 10 can be replaced or just the lens removed. The interaction of the first and second threads 8 allows for easy switching between magnifying sleeves with the same working distance but different magnification levels, according to the actual usage requirements of the wearer. The corrective lens ring 10 also features a bore that allows for simple rotation to adjust the lens axis position.

[0020] The structure after completion of the assembly of the mounting frame 1 and the magnifying sleeves 6 is in Fig. 4 and Fig. Figure 5 illustrates this, where distance D2 represents the interpupillary distance and distance D1 a segment length determined according to the working distance of the magnifying sleeves 6, depending on the respective focusing angle. Furthermore, the respective mounting ring 3 is inclined relative to the respective extension section 14 towards the wearer's body side, creating an obtuse angle α between the outer surface of the respective mounting ring 3 and the respective extension section 14. This angle of inclination α ensures that the wearer can observe in a relaxed posture and thus perform operations and other tasks without causing neck fatigue by excessively lowering the head.

[0021] The mountable surgical binocular loupe can further include a carrying arrangement, which may be a framed structure with or without a rim. In a rimless carrying arrangement, temples 15 are fixed through pre-drilled mounting holes in the optical lenses 5 by means of screws or snap fasteners. In a rimmed carrying arrangement, a frame 16 extends from the mounting frame 1 to two sides, or the frame 16 can be considered part of the mounting frame 1, with the temples 17 attached to the frame 16.

[0022] The carrying arrangement can also be a head support device comprising a head support section 22, a shock-absorbing joint holder 18, and a clamping device 19. The head support section 22 is a wearable part made of rubber band, its edge region, which encloses the head, having a rigid support section on which the shock-absorbing joint holder 18 is provided. The shock-absorbing joint holder 18 is attached to the head support section 22 and has three or more pivot points to facilitate adjustment of the overall position of the mounting frame 1. The clamping device 19 is located at one end region of the shock-absorbing joint holder 18 and can be mounted to the mounting holes of the crossbar 2 by means of screws or snap fasteners. This allows the mounting frame 1 to be detachably fixed by means of the clamping device 19.A headlamp 20 is attached to the damping joint holder 18 or to the mounting frame 1 and positioned between the two optical lenses 5. The headlamp 20 can be fixed to a rotary knob 21 of the clamping device 19 by means of a headlamp clamping device.

[0023] So far, only preferred embodiments of the present invention have been described, which in no way limits the scope of the present invention. All equivalent changes and modifications based on the scope of the patent application fall within the technical scope of the present invention.
