Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a hinge structure for a medical microscope. Background Technology

[0002] A medical microscope is a precision optical instrument used in the medical field, primarily for observing tiny objects or samples to assist doctors in diagnosis, pathological analysis, and surgical procedures. Through high-magnification lenses and high-brightness light source systems, it can provide high-definition, high-resolution images, ensuring precise observation of details. The design of a medical microscope typically includes core components such as a lens holder, rotation axis, connecting arm, focusing system, stage, illumination system, and a highly stable base. Its structural design prioritizes stability and adjustability, allowing users to adjust the observation angle and focal length as needed.

[0003] Existing medical microscopes still present some problems in use. For example, traditional medical microscopes typically consist of a base, arm, tube, stage, and mirror. In this structure, the mirror's angle adjustment is primarily used to adjust the field of view within the tube. However, current mirror adjustment methods usually only allow for simple oscillation adjustments and cannot provide precise light control. In dimly lit environments, users often need to constantly adjust the microscope's base or other parts, making the operation cumbersome and inefficient. Furthermore, the microscope's base and arm, and arm and tube, are usually connected by a linkage structure. This connection method limits the flexible adjustment of the arm or tube angle, resulting in certain operational inconveniences and limitations during use.

[0004] To address these issues, we provide a hinge structure for a medical microscope. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the reflector cannot be adjusted at multiple angles, and the base and the arm and the arm and the tube connected by the link lack flexible adjustment function. To this end, we propose a hinged structure for medical microscopes.

[0006] To achieve the above objectives, this application adopts the following technical solution: a hinge structure for a medical microscope, including a base, a microscope arm disposed on the top of the base, and a microscope tube disposed on one side of the microscope arm; an adjustment assembly disposed on the top of the base, the adjustment assembly including a support fixedly connected to one side of the top of the base, a lead screw movably connected to the inner cavity of the support, an adjustment plate threaded to the surface of the lead screw, a first adjustment seat fixedly connected to the top of the adjustment plate, and a reflector disposed on the top of the first adjustment seat, the adjustment assembly being used to adjust the angle of the reflector; a hinge assembly disposed on the top of the base, the hinge assembly including a mounting seat fixedly connected to one side of the top of the base, a first self-locking shaft movably connected to the inner cavity of the mounting seat, the surface of the first self-locking shaft being fixedly connected to one side of the inner cavity of the microscope arm, and a second self-locking shaft movably connected to one side of the inner cavity of the microscope arm, the surface of the second self-locking shaft being fixedly connected to one side of the surface of the microscope tube, the hinge assembly being used to install and adjust the microscope arm and the microscope tube.

[0007] Preferably, a lower self-locking rotating shaft is movably connected to the inner cavity of the first adjusting seat, and a second adjusting seat is fixedly connected to the surface of the lower self-locking rotating shaft.

[0008] Preferably, the inner cavity of the second adjusting seat is movably connected to an upper self-locking rotating shaft, and the surface of the upper self-locking rotating shaft is fixedly connected to one side of the inner cavity of the reflector.

[0009] Preferably, a rotating rod is movably connected to one side of the inner cavity of the support, a driving bevel gear is fixedly connected to one end of the rotating rod, and a driven bevel gear is fixedly connected to one side of the surface of the lead screw, wherein the driving bevel gear meshes with the driven bevel gear.

[0010] Preferably, a platform is fixedly connected to one side of the support, and a platform clamp is provided on both sides of the top of the platform.

[0011] Preferably, one end of the rotating rod extends to the outside of the support, and a handwheel is fixedly connected to one end of the rotating rod.

[0012] Preferably, a sliding groove is provided on one side of the support, and the inner cavity of the sliding groove is slidably connected to one side of the surface of the adjusting plate.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model achieves multi-angle precise adjustment of the reflector through an adjustment assembly consisting of a lead screw, an adjustment plate, a first adjustment seat, and a self-locking rotating shaft. The meshing transmission structure of the driving bevel gear and the driven bevel gear allows the user to fine-tune the reflector angle by turning the hand wheel, ensuring that light is accurately reflected to the lens barrel. This effectively improves the shortcomings of traditional reflectors that can only be adjusted by simple swinging. In addition, the sliding cooperation between the slide groove and the adjustment plate enhances the adjustment stability and avoids reflector displacement caused by external force interference. It is particularly suitable for medical environments with low light, significantly improving the clarity of observation and reducing the burden of repeated adjustments.

[0015] 2. This utility model, through the design of a hinged assembly, connects the microscope arm to the base via a first self-locking pivot, and the microscope tube to the arm via a second self-locking pivot. This allows both the arm and the tube to be independently adjusted for pitch and rotation, and maintains stable suspension at any angle thanks to the damping characteristics of the self-locking pivot. Compared to traditional fixed connection structures, this design significantly improves the microscope's degree of freedom of adjustment, allowing doctors to quickly adjust the viewing angle according to observation needs. It also avoids positional shifts caused by the weight of the microscope tube, ensuring stability and operational comfort during long-term use. It is especially suitable for high-precision medical scenarios such as surgical microscopes. Attached Figure Description

The upper self-locking shaft 14 is movably connected to the inner cavity of the second adjusting seat 13. The upper self-locking shaft 14 inside the second adjusting seat 13 can drive the reflector 8 to adjust its front and rear angles. The upper self-locking shaft 14, in conjunction with the lower self-locking shaft 12, enables left and right adjustment. The adjusting plate 6, driven by the lead screw 5, is raised and lowered, allowing for multiple angle adjustments to the reflector 8. The surface of the upper self-locking shaft 14 is fixedly connected to one side of the inner cavity of the reflector 8. A rotating rod 15 is movably connected to one side of the inner cavity of the support 4. One side of the rotating rod 15 is movably connected to the inner cavity of the support 4 via a limiting block. The rotating rod 15 can be supported and limited by the inner wall of one side of the support 4. One end of the rotating rod 15 is fixedly connected to the driving bevel gear 16, and one side of the lead screw 5 is fixedly connected to the driven bevel gear 17.

The inner cavity of the sliding groove 21 is slidably connected to one side of the surface of the adjusting plate 6.

[0028] Working Principle: During operation, this medical microscope hinge structure first provides overall stability through the base 1. When adjusting the angle of the reflector 8, the user rotates the handwheel 20 to drive the rotating rod 15, which in turn engages the driving bevel gear 16 with the driven bevel gear 17 on the lead screw 5. This causes the lead screw 5 to rotate and push the threaded adjustment plate 6 up and down along the slide groove 21, thereby adjusting the height of the reflector 8. Simultaneously, the lower self-locking shaft 12 in the first adjustment seat 7 and the upper self-locking shaft 14 in the second adjustment seat 13 allow for manual adjustment of the reflector 8's left-right and front-back tilt angles, respectively. The damping characteristics of the self-locking shafts ensure... Once the angle is fixed, there is no offset. For the adjustment of the arm 2 and the tube 3, the user can rotate the arm 2 to make it rotate horizontally around the first self-locking axis 10, or adjust the tube 3 to tilt around the second self-locking axis 11. The self-locking structure can be locked at any position to avoid pose drift caused by the weight of the tube 3. The sample on the stage 18 is fixed by the sample clamp 19. The multi-dimensional adjustment of the reflector 8 ensures that the light is accurately reflected to the tube 3, providing uniform illumination even in low-light environments. The entire system achieves coordinated adjustment of height, angle, and direction through mechanical linkage, taking into account both ease of operation and stability, and meeting the high-precision observation needs of medical scenarios.
