Technical Field

[0001] The utility model relates to the technical field of slit lamp microscopes, in particular to a slit lamp microscope. Background Art

[0002] The slit lamp microscope is an indispensable and important instrument for ophthalmic examination. It consists of an illumination system and a microscope. It can not only observe superficial lesions very clearly, but also adjust the focus and the width of the light source. For example, in the patent number "CN214073257U" and the patent name "A Slit Lamp Microscope", the longitudinal sliding device includes a first screw rod, a sliding groove is provided on the side of the bottom plate close to the fixing device, a movable plate is slidably connected in the sliding groove, a threaded hole is provided on the side of the bottom plate away from the observation device, the first screw rod passes through the threaded hole and abuts against the movable plate, and a first hand wheel is fixedly connected on the side of the first screw rod away from the bottom plate. The purpose of longitudinally adjusting the fixing device is achieved through the movement of the movable plate in the sliding groove. The fixing device is connected to the bottom plate through the sliding groove, the movable plate is separated from the sliding groove, and the fixing device is separated from the bottom plate, so as to achieve the function of quickly disassembling the fixing device, which is conducive to the rapid disassembly, cleaning and disinfection of the fixing device. However, the above structure still has the following problems in actual use:

[0003] Although the above-mentioned slit lamp microscope realizes the function of quickly disassembling the fixing device by separating the movable plate from the sliding groove and the fixing device from the bottom plate, its height is fixed. Since doctors have different heights and their eye positions are also different, it is easy for the doctor's eyes and the microscope to be not in the same plane. Therefore, the doctor needs to hunch over to use it, which easily leads to doctor fatigue and body aches.

[0004] Therefore, we proposed that slit lamp microscope can solve the above problems well. Utility Model Content

[0031] The arrangement of the base 1 allows the entire device to be supported, while the arrangement of the anti-sliding block 2 prevents the base 1 from sliding autonomously during use, thereby improving the stability of the device. The pneumatic push rod 7 is started, so that one end of the pneumatic push rod 7 drives the first moving block 3 to slide left and right, and the first moving block 3 slides left and right, so that one end of the first connecting rod 4 moves together, and the middle section of the first connecting rod 4 is connected to the second connecting rod 5 through a movable shaft, so that the middle section of the second connecting rod 5 moves together, so that the other end of the second connecting rod 5 drives the second moving block 6 to slide together, and the linkage structure formed between the first connecting rod 4 and the second connecting rod 5 drives the main board 8 to rise and fall, so that the main board 8 drives the entire device to rise and fall, and can be adjusted according to the height of the doctor, so as to ensure that the doctor's eyes and the microscope body 12 are in the same plane, so that the doctor does not need to hunch over to use it, thereby avoiding doctor fatigue and body aches.

[0032] Embodiment 2: Different from Embodiment 1, this embodiment facilitates adjusting the observation angle of the microscope body 12. Figure 1-Figure 2 The upper surface of the main board 8 is connected to a rotating column 9 by a bearing, and the upper end of the rotating column 9 is fixedly connected to a main support member 10, and the main support member 10 is arranged in an "L"-shaped structure, a slit lamp body 11 is welded and fixed to the upper surface of the main support member 10, and the upper end of the main support member 10 is fixedly connected to a microscope body 12;

[0033] Moreover, the main support member 10 can be rotated by the movable shaft connection formed between the rotating column 9 and the main board 8. The rotation of the main support member 10 can drive the microscope body 12 to rotate together, so as to facilitate the adjustment of the observation angle of the microscope body 12. The setting of the slit lamp body 11 not only provides lighting, but also can rotate with the main support member 10, so as to be more convenient to use.

[0034] Embodiment 3: Different from Embodiment 2, this embodiment facilitates supporting the patient's head, and the height of the support can be adjusted according to the height of the patient. Figure 1-Figure 5 A sleeve 13 is welded and fixed on the upper surface of the main board 8, and a telescopic rod 14 is slidably engaged inside the sleeve 13, and the upper end of the telescopic rod 14 is fixed to the arc plate 15, and a cushion 16 is bonded to the inner side of the arc plate 15, and the outer side of the telescopic rod 14 is provided with card holes 17 at equal intervals, and the card holes 17 and the card rod 18 are engaged with each other, and the front side of the sleeve 13 is slidably provided with a card rod 18, and the outer side of the card rod 18 is sleeved with a return spring 19, and the front end of the return spring 19 is fixed to the card rod 18, and the rear end of the return spring 19 is fixed to the sleeve 13;

[0035] By setting the arc plate 15 above the telescopic rod 14, it is convenient to support the patient's head, so as to avoid the patient's head being raised for too long during examination and lowering the head due to pain, which may cause the microscope body 12 to be unable to be in the same plane with the patient's eyes. By pulling the clamping rod 18, one end of the clamping rod 18 is separated from the clamping hole 17, and then the telescopic rod 14 is lifted from the sleeve 13. When it is adjusted to a specified position, the clamping rod 18 is released, and the clamping rod 18 is reset by the elastic force of the reset spring 19, so that one end of the clamping rod 18 is again engaged with the clamping hole 17, thereby limiting the position of the telescopic rod 14. Through the above-mentioned structural setting, the support height of the arc plate 15 can be adjusted according to different patients to ensure that the patient's eyes are always in the same plane with the microscope body 12.
