Technical Field

[0001] This application relates to the technical field of medical devices, and more particularly, to a wide-angle auxiliary lens system. Background Art

[0002] In modern microsurgery, surgical microscopes are widely used to improve surgical precision and patient safety. However, existing surgical microscope systems usually suffer from the problem of limited field of view, unable to provide a sufficient wide-angle field of view, making it difficult for surgeons to comprehensively observe the surgical area during complex surgical procedures. When precise operations at multiple angles are required during surgery, the surgeon needs to frequently adjust the position of the microscope, increasing the surgical time and operation difficulty. In the prior art, this problem is usually attempted to be solved by adding multiple fixed lenses or using a method of manually adjusting the lens angle, but these methods have defects such as inconvenient operation and poor lens fixity, resulting in low surgical efficiency and complex operation.

[0003] Based on the above disadvantages of the prior art, there is an urgent need for a wide-angle auxiliary lens system. Summary of the Invention

A groove for cooperating with the rubber ring is formed on the inner wall of the mounting ring body, and the rubber

[0007] ring is fixedly arranged within the groove, and the auxiliary lens is fixedly arranged between the mounting platform and the rubber ring.

[0008] Further, the mounting platform includes at least three supporting pieces, and adjacent supporting pieces are spaced apart.

[0009] Further, all the supporting pieces are equally spaced.

[0010] Further, the rubber ring is a black high-temperature resistant silicone rubber ring.

[0011] Further, the height of the lens mounting ring is greater than or equal to the thickness of the cantilever body, and the lower surface of the lens mounting ring is flush with the lower surface of the cantilever body.

[0012] Further, the connecting part between the middle of the cantilever body and the lens mounting ring is an arc protruding outward.

[0026] Such as Figure 1As shown, this embodiment provides a wide-angle auxiliary lens 22 system, which includes a connecting arm 1 and a double-mirror cantilever 2. The connecting arm 1 is used to fix the device on the surgical microscope and at the same time allows the device to rotate freely within a certain range. The double-mirror cantilever 2 is the main part of the device and includes an auxiliary lens 22 for wide-angle observation. One end of the connecting arm 1 is rotatably connected to the folding cantilever on the surgical microscope, allowing the doctor to adjust the position of the device according to needs to obtain the best view. The double-mirror cantilever 2 includes a cantilever body 21, an auxiliary lens 22, and a lens mounting ring 23. The cantilever body 21 is the main part of the entire cantilever structure. The auxiliary lens 22 is used to provide a wide-angle view, and the lens mounting ring 23 is used to fix the position of the auxiliary lens 22. The lens mounting ring 23 is fixed at both ends of the cantilever body 21, and this setting can ensure the stability and accuracy of the auxiliary lens 22. The center of the cantilever body 21 is connected to the end of the connecting arm 1 far from the surgical microscope, and this connection is rotatable, enabling the entire device to be flexibly adjusted during the operation. The auxiliary lens 22 is fixed within the lens mounting ring 23, and this fixing method ensures that the lens does not shift during the operation, thus providing a stable and clear view. The design of the lens mounting ring 23 and the auxiliary lens 22 ensures the stability of the lens during use and prevents it from shifting due to accidental collision or vibration, thereby providing a stable observation view. By compensating for the eye axis length, the doctor can operate on the surgical area more precisely, reduce surgical errors, and improve the success rate of the operation.

[0027] Preferably, as Figure 2As shown, the lens mounting ring 23 includes a mounting ring body 231, a mounting platform 232, and a rubber ring 233. The mounting platform 232 is provided on the inner wall of the mounting ring body 231, and a groove for cooperating with the rubber ring 233 is formed on the inner wall of the mounting ring body 231. The lens mounting ring 23 is a structural part for fixing the auxiliary lens 22, ensuring that the auxiliary lens 22 maintains a stable and correct position during use. The mounting platform 232 is provided on the inner wall of the mounting ring body 231 and is a direct supporting structure for the auxiliary lens 22. It protrudes along the inner side of the mounting ring body 231, providing a stable supporting surface. The rubber ring 233 is arranged in the groove on the inner wall of the mounting ring body 231 and is used to fix the auxiliary lens 22. The rubber ring 233 can provide a certain elasticity, ensuring that the lens can be firmly fixed during installation, and at the same time, it can also reduce the impact of vibration and shock on the lens. A groove is formed on the inner wall of the mounting ring body 231 for cooperating with the rubber ring 233. The design of the groove enables the rubber ring 233 to be tightly fixed on the inner wall of the mounting ring body 231, preventing the rubber ring 233 and the auxiliary lens 22 from shifting during use. The auxiliary lens 22 is fixed between the mounting platform 232 and the rubber ring 233. This dual fixing method ensures the stability of the lens. The mounting platform 232 provides rigid support, while the rubber ring 233 provides elastic fixation, enabling the lens to be firmly fixed and buffer external vibrations. By arranging the rubber ring 233 on the mounting platform 232 and fixing the auxiliary lens 22 between the mounting platform 232 and the rubber ring 233, the stability of the auxiliary lens 22 is significantly enhanced. The elastic fixation of the rubber ring 233 can effectively absorb and relieve external vibrations and shocks, preventing the lens from shifting.

[0028] Preferably, as Figure 3 shown, the mounting platform 232 includes at least three supporting pieces 2321, and the adjacent supporting pieces 2321 are arranged at intervals. The supporting pieces 2321 provide reliable supporting points, firmly fixing the auxiliary lens 22 on the mounting platform 232. The multiple supporting pieces 2321 are evenly distributed, with diverse supporting points, ensuring the stability of the lens and avoiding the lens tilt or shift caused by uneven single-point force. Further, the interval design between the supporting pieces 2321 allows more light to enter the auxiliary lens 22 through these gaps. The traditional complete supporting surface may block part of the light, while the interval setting of the supporting pieces 2321 minimizes the light blockage, enabling more light to pass through, increasing the incident range of light, and thus improving the brightness and visibility of the surgical area.

[0029] Preferably, as Figure 3 shown, all the supporting pieces 2321 are arranged at equal intervals. The equal interval arrangement of the supporting pieces 2321 provides a uniform distribution of supporting points, making the force on the auxiliary lens 22 more uniform, avoiding the lens tilt or shift caused by excessive unilateral force, and enhancing the stability and fixation of the lens.

[0030] Preferably, the rubber ring 233 is a black high-temperature resistant silicone rubber ring. Silicone rubber has excellent heat resistance, elasticity, and chemical stability, while black materials can effectively absorb light. The black rubber ring 233 can effectively absorb light and reduce reflection. At the same time, the auxiliary lens 22 and the lens mounting ring 23 will have different thermal expansions during the high-temperature sterilization process. The black high-temperature resistant silicone rubber ring 233 can effectively absorb and relieve the stress caused by different thermal expansion coefficients, thus avoiding damage to the auxiliary lens 22 due to thermal stress. The elastic properties of silicone rubber enable it to provide the necessary buffering and absorb stress during thermal expansion, protecting the integrity of the lens.

[0031] Preferably, the height of the lens mounting ring 23 is greater than or equal to the thickness of the cantilever body 21, and the lower surface of the lens mounting ring 23 is flush with the lower surface of the cantilever body 21.

[0032] Preferably, the connecting part between the middle of the cantilever body 21 and the lens mounting ring 23 is an arc protruding outward. This design takes into account the safety factors when the operating table is lifted or the position of the microscope is adjusted improperly. If the auxiliary lens 22 or the cantilever body 21 accidentally contacts the patient's cornea, the arc-shaped lower edge can make the cantilever body 21 slide over the cornea more smoothly while reducing the pressure on the cornea.

[0033] Preferably, the material of the cantilever body 21 is stainless steel. Stainless steel has the characteristics of high strength, corrosion resistance, and wear resistance, and is suitable for the manufacture of medical devices.

[0034] Preferably, the surface of the cantilever body 21 is provided with anti-slip texture 211 to provide additional friction, prevent hand slippage during the operation, and improve the accuracy and operation efficiency of the surgery.

[0035] Preferably, as Figure 2 shown, the double-lens cantilever 2 further includes a dust cover 24, and the dust cover 24 is fixedly arranged at both ends of the lens mounting ring 23. When not in use, the dust cover 24 provides effective dust protection, preventing dust, dirt, and other impurities from entering the auxiliary lens 22 and keeping the lens clean and transparent.

[0036] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
