Description

Technical Field

[0001] This utility model belongs to the field of endoscope technology, and in particular relates to an endoscope adjustment mechanism and an endoscope. Background Technology

[0002] As an important tool that can be used to observe and inspect in confined spaces, endoscopes are widely used in many fields such as industrial inspection, scientific research, and medical diagnosis. In the industrial field, they can be used to check for internal corrosion of pipes and wear of mechanical parts. In scientific research, they can help observe biological samples and microstructures. In the medical field, they are indispensable, helping doctors to intuitively understand the condition of internal organs.

[0003] Most existing endoscope adjustment mechanisms are complex in structure and cumbersome in operation. Operators need to spend a lot of energy to operate and adjust them, which not only reduces work efficiency, but also has poor adjustment accuracy and flexibility. It is difficult to accurately deliver the observation end to a specific position in a complex space, and it is impossible to achieve detailed observation from multiple angles and all directions. At present, the illumination components of most endoscopes are usually set in a fixed position and cannot be adjusted in real time according to changes in the observation angle and target area. When the endoscope observation end is adjusted to a special angle, the light is easily blocked or reflections are formed on the lesion surface, resulting in uneven brightness in the observation area and blurred images.

[0004] To address these issues, we provide an endoscope adjustment mechanism and an endoscope. Utility Model Content

[0005] The purpose of this invention is to provide an endoscope adjustment mechanism and an endoscope. By combining the lens adjustment component and the illumination adjustment component, it solves the problems of existing endoscope adjustment mechanisms being mostly complex in structure, cumbersome in operation, and unable to adjust the illumination in real time according to changes in the observation angle and target area.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an endoscope adjustment mechanism, comprising a housing, a first positioning plate fixedly connected to one side of the housing, a second positioning plate disposed on one side of the first positioning plate, a lens adjustment assembly disposed on one side of the second positioning plate, an illumination adjustment assembly disposed on one side of the lens adjustment assembly, the lens adjustment assembly including a protective cover, one side of the protective cover being fixedly connected to the second positioning plate, a knob movably connected to the surface of the protective cover via a rotating shaft, a first gear fixedly connected to one side of the knob, a first internal gear disposed within the inner cavity of the protective cover, one side of the first internal gear meshing with the first gear, a connecting plate fixedly connected to the surface of the first internal gear, and a [missing information - likely a component or element] fixedly connected to one side of the connecting plate. The conduit has a mounting cylinder fixedly connected to one side. Through a precise gear transmission design, it achieves efficient and accurate lens adjustment. When the operator turns the knob, the first gear and the first internal gear mesh with each other, converting the rotational motion into the rotation of the conduit and the mounting cylinder. This allows the endoscope to flexibly adjust its angle and accurately align with the observation target. Compared with traditional adjustment methods, this gear transmission structure is not only easy to operate, but also effectively reduces adjustment errors, allowing the operator to quickly and accurately adjust the lens to the ideal position, significantly improving observation efficiency and accuracy. At the same time, the protective cover provides protection for the internal transmission components, preventing dust and impurities from entering and affecting the transmission performance, and extending the service life of the adjustment mechanism.

[0008] This invention is further configured such that the lighting adjustment assembly includes a rotating frame, the surface of which is movably connected to the mounting cylinder, a second internal gear fixedly connected to the inner wall of the rotating frame, a motor fixedly connected to one side of the inner cavity of the mounting cylinder, a second gear fixedly connected to the output end of the motor, the second gear meshing with the second internal gear, and a lighting lamp fixedly connected to one side of the rotating frame. The invention employs a motor-driven gear meshing transmission method. When the motor starts, the second gear drives the second internal gear to rotate, thereby causing the rotating frame connected to the second internal gear to rotate. The lighting lamp fixed to one side of the rotating frame adjusts its angle accordingly, enabling precise and rapid adjustment of the lighting direction according to observation needs. This ensures that the observation area is always evenly illuminated, avoiding blurred vision caused by light obstruction or reflection, providing doctors with clear and stable lighting conditions, and improving the accuracy of diagnosis and operation.

[0009] The present invention is further provided that a handle is fixedly connected to the bottom of the housing, and the surface of the handle is provided with anti-slip texture. In actual operation, the anti-slip texture increases the friction between the hand and the handle, effectively preventing the hand from slipping during operation and providing the doctor with a stable and comfortable grip.

[0010] The present invention is further configured such that a movable seat is provided on the surface of the housing, and a display screen is movably connected to the surface of the housing via the movable seat. The movable connection of the display screen via the movable seat gives the display screen angle adjustment flexibility. Doctors can freely adjust the angle and position of the display screen according to their own observation habits and actual operating scenarios, ensuring that they can view image information clearly and comfortably in different postures and environments.

[0011] The present invention is further configured such that a connecting line is fixedly connected to one side of the housing, and the connecting line is connected to an external display screen, which greatly expands the application scenarios of the device.

[0012] The present invention is further configured such that positioning holes are provided on the surface of the first positioning plate and the surface of the second positioning plate, and the positioning holes are symmetrically arranged. The symmetrically arranged positioning holes on the surfaces of the first positioning plate and the second positioning plate facilitate the installation and fixation of the endoscope adjustment mechanism. The adjustment mechanism can be stably installed on other equipment or structures through the positioning holes. The symmetrical arrangement ensures the structural balance and stability after installation and enhances the reliability of the overall mechanism.

[0013] The present invention is further configured such that a protective shell is fixedly connected to one side of the protective cover, and the protective shell is fitted onto the surface of the conduit. The protective shell provides reliable protection for the conduit. During the use of the equipment, the protective shell can effectively block dust, liquid and other impurities from entering, prevent the conduit from being subjected to external collisions or wear, protect the integrity of the internal circuits and components of the conduit, and extend the service life of the conduit.

[0014] An endoscope includes a positioning groove and the aforementioned endoscope adjustment mechanism. The positioning groove is located on one side of the mounting cylinder, and an endoscope lens is fixedly connected to the inner cavity of the positioning groove. The positioning groove is used to fix the endoscope lens, which can accurately position the endoscope lens, ensure its stable position during adjustment, and guarantee the accuracy and stability of the observed images.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses a knob to drive the first gear and the first internal gear to mesh and transmit power, allowing the catheter and mounting cylinder to rotate flexibly. Compared with the traditional manual adjustment method, this gear transmission structure can accurately convert the rotational force of the operator's hand into the rotation of the catheter and mounting cylinder, realizing precise control of the endoscope angle. In actual operation, even small angle adjustment needs can be quickly responded to by turning the knob, avoiding repeated adjustments caused by inaccurate force control and inaccurate adjustment path in traditional manual adjustment, and greatly saving adjustment time.

[0017] 2. This utility model uses a motor to drive the second gear and the second internal gear to control the rotating frame to drive the lighting lamp to rotate synchronously, ensuring that the lighting light can always evenly cover the observation area regardless of the lens angle, effectively avoiding light blockage or reflection, and providing stable lighting conditions for clear observation.

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0027] Please see Figure 1-6This utility model is an endoscope adjustment mechanism, including a housing 1. A first positioning plate 2 is fixedly connected to one side of the housing 1. A second positioning plate 3 is provided on one side of the first positioning plate 2. A lens adjustment assembly 4 is provided on one side of the second positioning plate 3. An illumination adjustment assembly 5 is provided on one side of the surface of the lens adjustment assembly 4. The lens adjustment assembly 4 includes a protective cover 41. One side of the protective cover 41 is fixedly connected to the second positioning plate 3. A knob 42 is movably connected to the surface of the protective cover 41 through a rotating shaft. A first gear 43 is fixedly connected to one side of the knob 42. A first internal gear 44 is provided in the inner cavity of the protective cover 41. One side of the first internal gear 44 meshes with the first gear 43. A connecting plate 45 is fixedly connected to the surface of the first internal gear 44. A conduit 46 is fixedly connected to one side of the connecting plate 45. An installation cylinder 47 is fixedly connected to one side of the conduit 46.

[0028] Specifically, the precise design of the gear transmission enables efficient and accurate lens adjustment. When the operator turns the knob 42, the first gear 43 and the first internal gear 44 mesh with each other, converting the rotational motion into the rotation of the guide tube 46 and the mounting cylinder 47. This allows the endoscope lens 12 to flexibly adjust its angle and accurately align with the observation target. Compared with traditional adjustment methods, this gear transmission structure is not only easy to operate but also effectively reduces adjustment errors, allowing the operator to quickly and accurately adjust the lens to the ideal position, significantly improving observation efficiency and accuracy. At the same time, the protective cover 41 provides protection for the internal transmission components, preventing dust and impurities from entering and affecting the transmission performance, and extending the service life of the adjustment mechanism. Example

[0029] Please see Figure 1-6 Based on Embodiment 1, the lighting adjustment assembly 5 includes a rotating frame 51, the surface of which is movably connected to the mounting cylinder 47, a second internal gear 52 fixedly connected to the inner wall of the rotating frame 51, a motor 53 fixedly connected to one side of the inner cavity of the mounting cylinder 47, a second gear 54 fixedly connected to the output end of the motor 53, the second gear 54 meshing with the second internal gear 52, a lighting lamp 55 fixedly connected to one side of the rotating frame 51, a handle 6 fixedly connected to the bottom of the housing 1, the surface of the handle 6 being provided with anti-slip texture, a movable seat provided on the surface of the housing 1, a display screen 7 movably connected to the surface of the housing 1 through the movable seat, a connecting line 8 fixedly connected to one side of the housing 1, the connecting line 8 being connected to the external display screen 7, positioning holes 9 being provided on the surface of the first positioning plate 2 and the surface of the second positioning plate 3, the positioning holes 9 being symmetrically arranged, a protective shell 10 fixedly connected to one side of the protective cover 41, the protective shell 10 being sleeved on the surface of the guide tube 46.

[0030] Specifically: A gear-driven transmission system is employed, where motor 53 starts, and the second gear 54 drives the second internal gear 52 to rotate. This, in turn, causes the rotating frame 51 connected to the second internal gear 52 to rotate. The lighting lamp 55, fixed to one side of the rotating frame 51, adjusts its angle accordingly. This allows for precise and rapid adjustment of the lighting direction based on observation needs, ensuring the observation area is always evenly illuminated. This avoids blurred vision caused by light obstruction or reflection, providing doctors with clear and stable lighting conditions and improving the accuracy of diagnosis and operation. During actual operation, the anti-slip texture increases the friction between the hand and the handle 6, effectively preventing hand slippage and providing doctors with a stable and comfortable grip. The display screen 7 is movably connected via a movable base, giving the display screen 7 flexibility in angle adjustment. Doctors can adjust the angle according to their observation habits and actual operating scenarios. The angle and position of the display screen 7 can be freely adjusted to ensure clear and comfortable viewing of image information in different postures and environments. The connecting cable 8 connects to the external display screen 7, greatly expanding the application scenarios of the device. The positioning holes 9 symmetrically opened on the surfaces of the first positioning plate 2 and the second positioning plate 3 provide convenience for the installation and fixation of the endoscope adjustment mechanism. The adjustment mechanism can be firmly installed on other equipment or structures through the positioning holes 9. The symmetrical arrangement ensures the structural balance and stability after installation, enhancing the reliability of the overall mechanism. The protective shell 10 is fitted on the surface of the catheter 46, providing reliable protection for the catheter 46. During the use of the device, the protective shell 10 can effectively block dust, liquid and other impurities from entering, prevent the catheter 46 from being damaged by external collisions or wear, protect the integrity of the internal circuits and components of the catheter 46, and extend the service life of the catheter 46. Example

[0031] Please see Figure 1-6 The present invention is an endoscope, including a positioning groove 11 and the aforementioned endoscope adjustment mechanism. The positioning groove 11 is opened on one side of the mounting cylinder 47, and an endoscope lens 12 is fixedly connected to the inner cavity of the positioning groove 11.

[0032] Specifically: the positioning groove 11 is used to fix the endoscope lens 12, which can accurately position the endoscope lens 12, ensure its stable position during adjustment, and guarantee the accuracy and stability of the observed image.

[0033] The working principle of this utility model is as follows: the operator rotates the knob 42, and the knob 42 drives the first gear 43 to rotate synchronously through the rotating shaft. Since the first gear 43 meshes with the first internal gear 44, the rotational motion of the first gear 43 is transmitted to the first internal gear 44, causing it to rotate in the inner cavity of the protective cover 41. The connecting plate 45 fixed on the surface of the first internal gear 44 rotates accordingly, thereby driving the connected guide tube 46 to rotate. Finally, the mounting cylinder 47 on one side of the guide tube 46 rotates, and the endoscope 12 changes its angle with the mounting cylinder 47 to achieve alignment with the observation target.

[0034] When the lighting direction needs to be adjusted, the motor 53 is started, and the second gear 54 at the output end of the motor 53 begins to rotate. The second gear 54 meshes with the second internal gear 52 on the inner wall of the rotating frame 51, transmitting the power of the motor 53 to the rotating frame 51. Driven by the second internal gear 52, the rotating frame 51 rotates around the connection point with the mounting cylinder 47. The lighting lamp 55 fixed on one side of the rotating frame 51 also rotates synchronously. Through the precise control of the motor 53, the angle of the lighting lamp 55 can be quickly adjusted to ensure that the observation area is always evenly illuminated, avoiding light obstruction or reflection that affects the observation effect.

[0035] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
