[0027] The following is for reference. Figures 1-7 This invention describes an image query device 100 according to an embodiment of the present invention.

[0028] like Figures 1-7 As shown, the image query device 100 according to an embodiment of the present utility model includes a base 1, a lifting device 2, a connecting arm 3, and an imaging device 4.

[0029] Specifically, the lifting device 2 is located on the base 1 in the first direction (e.g., Figure 1 The lifting device 2 is located on one side (vertical direction) and is movable along the first direction. The connecting arm 3 is rotatably mounted at the end of the lifting device 2 furthest from the base 1, and the connecting arm 3 is movable along the second direction (e.g., vertical direction). Figure 1 The first direction extends in the left-right direction, and the second direction is perpendicular to the first direction. The imaging device 4 is located at the end of the connecting arm 3 away from the lifting device 2. In the first direction, the imaging device 4 is rotatable around the connection point between the connecting arm 3 and the imaging device 4. The imaging device 4 includes a housing 41, a display screen 42, and an imaging lens 43. The display screen 42 and the imaging lens 43 are both mounted on the housing 41. The signal light emitted by the display screen 42 is projected onto the imaging lens 43. The signal light passes through the imaging lens 43 and forms a floating real image 44 in the air that is mirror-symmetrical to the display screen 42. The floating real image 44 is formed in the air and does not require any medium.

[0030] For example, in Figure 1 and Figure 2 In the example, the base 1 supports the lifting device 2, the connecting arm 3, and the imaging device 4, thereby increasing the stability of the image query device 100. The lifting device 2, mounted on the base 1, can be adjusted to accommodate the height of medical personnel, making the image query device 100 suitable for use by medical personnel of different heights and avoiding discomfort caused by prolonged periods of looking down or up. The connecting arm 3 is positioned away from the base 1 from the lifting device 2, which helps ensure the proper height of the imaging device 4, thus facilitating observation and operation of the imaging device 4 by medical personnel.

[0031] The connection between the connecting arm 3 and the imaging device 4 serves as a rotation axis. The imaging device 4 rotates in the first direction around the aforementioned rotation axis, enabling the imaging device 4 to switch between frontal, top, and bottom angles. This allows the imaging device 4 to adapt to the usage habits of different medical staff, namely, the observation angles required by medical staff, such as frontal, bottom, and top views. It also facilitates the operation of the floating real image 44 by medical staff, reduces physical contact during image reading, and makes it more convenient for medical staff to operate.

[0032] The housing 41 of the imaging device 4 integrates the display screen 42 and the imaging lens 43, enabling the signal light energy from the display screen 42 to form a floating real image 44 on the imaging lens 43. This allows medical personnel to operate the device remotely. In actual use, medical personnel do not need to touch the mechanical buttons of the image query device 100 or the buttons on the display screen 42; they only need to touch the floating real image 44. The floating real image 44 transmits signals to the display screen 42, which then changes according to the signals, altering the content of the floating real image 44. This allows for interaction between the user and the display screen 42. The display screen 42 can adjust the height of the lifting device 2 via operation commands, and / or the imaging device 4 can rotate around the connection point between the connecting arm 3 and the imaging device 4 as a pivot point to adjust its angle. This allows for the manipulation of the height and tilt of the imaging device 4, ensuring that its height and / or tilt are suitable for the medical personnel's observation and operation of the floating real image 44.

[0033] Therefore, the height and tilt of the floating real image 44 of the image retrieval device 100 were adjusted to make it suitable for use by medical staff, reducing their physical fatigue and improving their efficiency and accuracy in reading images using the device. The image retrieval device 100 can adapt to different medical staff. Specifically, each medical staff member has a different height and operating habits; the height and angle adjustable image retrieval device 100 can be adjusted according to individual needs, allowing each staff member to operate in the most comfortable posture, reducing fatigue and discomfort, and improving work efficiency. At the same time, the height and angle requirements of the image retrieval device 100 will also vary in different medical scenarios. The image retrieval device 100, with its height and angle adjustable via non-contact buttons, can be adjusted according to different medical scenarios, avoiding cross-infection between medical staff and patients.

[0034] Furthermore, medical staff do not need to repeatedly remove and put on gloves, reducing cumbersome operational steps during surgery, minimizing physical contact with and operation of the image query device 100, reducing the chance of contact with viruses and bacteria, and lowering the risk of cross-infection during the adjustment of the image query device 100, thereby improving the cleanliness of the image query device 100. According to the embodiment of this utility model, the image query device 100, by operating the floating real image 44 of the imaging device 4, can adjust the height of the lifting device 2 and / or the angle of rotation of the imaging device 4 around the connection point between the connecting arm 3 and the imaging device 4. This allows for the manipulation of the height and / or tilt of the imaging device 4, making it suitable for the observation and operation needs of medical staff on the floating real image 44, reducing the physical fatigue of medical staff, and improving the efficiency and accuracy of medical staff in interpreting images using the aforementioned image query device 100.

[0035] According to some embodiments of this utility model, refer to Figure 1 The connecting arm 3 includes a first sub-arm 31, a second sub-arm 32, and two third sub-arms 33. One end of the first sub-arm 31 is rotatably connected to the lifting device 2, and the first sub-arm 31 extends along a second direction. The second sub-arm 32 is connected to the other end of the first sub-arm 31, and the second sub-arm 32 extends along a third direction (e.g., Figure 1 The connecting arms 3 extend in the front-back direction (as shown in the image), with the third, second, and first directions orthogonal to each other. Two third sub-arms 33 are respectively connected to the two ends of the second sub-arm 32, each extending along the second direction and rotatably connected to the housing 41. In other words, the connecting arms 3 are symmetrically arranged, with the first sub-arm 31 and the second arm 32 arranged in a T-shape, and the two third arms 33 symmetrically positioned on the side of the second sub-arm 32 away from the first arm 31. The two third arms 33 are correspondingly rotatably connected to the housing 41, thereby increasing the stability of the connecting arms 3 connected to the housing 41, and simultaneously increasing the rotational stability and reliability of the housing 41.

[0036] Furthermore, referring to Figure 1 At least one of the two third sub-arms 33 has a first motor 5 located at one end adjacent to the housing 41, and the output shaft of the first motor 5 is connected to the housing 41. Alternatively, one of the two third sub-arms 33 may have a first motor 5 located at one end adjacent to the housing 41; or, both third sub-arms 33 may have a first motor 5 located at one end adjacent to the housing 41. The first motor 5 drives the housing 41, thereby facilitating the control of the housing 41 to rotate around the connection point between the connecting arm 3 and the imaging device 4 as a rotation axis, adjusting the angle of the housing 41. This makes it easier for the angle of the floating real image 44 of the imaging device 4 to suit the observation and usage habits of medical personnel, improving the efficiency of image reading operations.

[0037] Furthermore, referring to Figure 1The image retrieval device 100 also includes a second motor 6, which is located between the lifting device 2 and the first sub-arm 31. The second motor 6 is fixedly connected to the lifting device 2, and its output shaft is connected to the first sub-arm 31. With this configuration, rotation of the output shaft of the second motor 6 can drive the first sub-arm 31 to rotate around the lifting device 2, i.e., rotation on a horizontal plane. This facilitates adjustment of the orientation of the imaging device 4, ensuring that the floating real image 44 formed by the imaging device 4 faces the medical staff, avoiding the need for manual repositioning of the image retrieval device 100 by the medical staff, and increasing the cleanliness of the image retrieval device 100.

[0038] According to some embodiments of this utility model, refer to Figure 1 and Figure 4 The lifting device 2 includes an electric lifting rod 21, a first sleeve 22, and a second sleeve 23. The electric lifting rod 21 is movable along a first direction. The first sleeve 22 is fitted around the outer periphery of the electric lifting rod 21 and is connected to the base 1. The second sleeve 23 is fitted around the outer periphery of the first sleeve 22 and the electric lifting rod 21, and is slidably engaged with the first sleeve 22 and fixedly connected to the electric lifting rod 21. The use of the electric lifting rod 21 increases the convenience of lifting, thereby facilitating the adjustment of the floating real image 44 page of the image query device 100. One end of the first sleeve 22 is connected to the base 1, and the other end of the first sleeve 22, away from the base 1, is slidably engaged with the second sleeve 23. The second sleeve 23 moves away from or closer to the first sleeve 22 synchronously with the lifting of the electric lifting rod 21. Thus, the cooperation of the first sleeve 22 and the second sleeve 23 helps to protect the electric lifting rod 21, increases the cleanliness of the lifting device 2, and improves the cleanliness of the image query device 100.

[0039] Furthermore, referring to Figure 4 The electric lifting mast 21 includes a first mast segment 211 and a second mast segment 212 connected to each other. The outer diameter of the first mast segment 211 is larger than the outer diameter of the second mast segment 212. A first sleeve 22 is fitted around the outer periphery of the second mast segment 212. With this configuration, the end of the first sleeve 22 away from the base 1 can abut against the second mast segment 212, thus limiting the descent path of the second mast segment 212 and preventing excessive descent from the first mast segment 211 towards the second mast segment 212. This improves the reliability of the electric lifting mast 21, allowing it to reliably descend to a fixed height, facilitating the storage of the image query device 100. Simultaneously, the cooperation of the first sleeve 22 and the second sleeve 23 enhances the protective stability of the electric lifting mast 21.

[0040] According to some embodiments of this utility model, refer to Figure 1 , Figure 5 and Figure 6The image retrieval device 100 also includes a control device 7, which is mounted on the lifting device 2. The control device 7 includes a charging module 71, a step-down module 72, and a controller 73. The charging module 71 is electrically connected to the step-down module 72 and the controller 73. The controller 73 is electrically connected to the first motor 5, the second motor 6, and the electric lifting rod 21. The charging module 71 can provide stable voltage and current output, ensuring the stable performance of the image retrieval device 100 and facilitating medical operations in locations without power outlets. The fast charging function of the charging module 71 can shorten the charging time of the image retrieval device 100, improve its availability, reduce its dependence on fixed power outlets, make the medical space more organized and tidy, avoid safety hazards caused by messy power cords, and provide greater flexibility for the overall layout and space utilization of the hospital. The step-down module 72 can be used to power various modules and motors.

[0041] The controller 73 connects and works in coordination with the first motor 5, the second motor 6, and the electric lifting rod 21 to form a complete automated control system. Specifically, refer to... Figure 6 The controller 73 can control the operation of at least one of the first motor 5, the second motor 6, and the electric lifting rod 21 to enable the imaging device 4 of the image query device 100 to rotate around the connection between the connecting arm 3 and the imaging device 4 as the rotation axis, and / or, the imaging device 4 to rotate around the lifting device 2 as the center; and / or, the imaging device 4 to rise and fall, thereby adjusting the angle and height of the imaging device 4, so that the floating real image 44 formed by the imaging device 4 is suitable for the observation and operation needs of medical staff.

[0042] According to some embodiments of this utility model, refer to Figure 1The base 1 includes a body 11 and multiple support rods 12. In this description, "multiple" means two or more. The body 11 is connected to the lifting device 2. The multiple support rods 12 are spaced apart circumferentially along the body 11, each support rod 12 extends away from the body 11, and each support rod 12 has a caster wheel 13 connected to its free end. The base 1 is used to support the weight of the entire image query device 100. Three or four support rods 12 are spaced apart circumferentially along the body 11, which is not specifically limited here. The arrangement of multiple support rods 12 ensures the support stability of the base 1 while reducing the volume and weight of the base 1, thereby facilitating the movement and storage of the image query device 100. The caster wheel 13 can rotate 360 ​​degrees, allowing the image query device 100 equipped with the caster wheel 13 to move in any direction without changing the orientation of the image query device 100, greatly improving the flexibility and ease of position adjustment of the image query device 100. At the same time, it makes the image query device 100 easier to push or pull, reducing the force required for operation. In addition, the use of casters 13 allows the image retrieval device 100 to adapt to the complex space of the hospital. The shock absorption and braking functions of casters 13 help improve the safety of the image retrieval device 100 and also facilitate cleaning and maintenance.

[0043] According to some other embodiments of the present invention, refer to Figure 1 The lifting device 2 is equipped with a handrail 8, which is located adjacent to the connecting arm 3. The handrail 8 facilitates the movement of the imaging query device 100 by medical personnel. It provides a stable grip point, especially when changing direction or navigating narrow spaces, allowing for more precise directional control. Simultaneously, it allows medical personnel to exert force in a more natural posture, reducing unnecessary physical exertion and lowering the risk of muscle or joint injuries caused by improper force. Furthermore, when medical personnel push the imaging query device 100, the handrail 8 helps maintain balance, preventing the device from tilting or tipping over, thus increasing the safety of operating the device.

[0044] The handrail 8 is located near the connecting arm 3 and away from the imaging device 4, which can prevent the floating real image 44 of the imaging device 4 from being blocked during movement, and further facilitate the use of the image query device 100 by medical staff.

[0045] According to some specific embodiments of this utility model, refer to Figure 1 and Figure 2An opening 411 is formed on the side of the housing 41 away from the connecting arm 3. The imaging device 4 also includes a bracket 45 and an interactive sensor 46. The bracket 45 is located inside the housing 41, and the display screen 42 and the imaging lens 43 are both mounted on the bracket 45, with the imaging lens 43 facing the opening 411. The interactive sensor 46 is mounted on the bracket 45, located on the side of the imaging lens 43 away from the base 1. That is, the display screen 42, the imaging lens 43, and the interactive sensor 46 are mounted on the bracket 45 inside the housing 41, which helps to increase the stability of the display screen 42, the imaging lens 43, and the interactive sensor 46. The display screen 42 can be stably facing the imaging lens 43, and the imaging lens 43 can be stably facing the opening 411, thereby improving the integrity and stability of the presentation of the floating real image 44. The interactive sensor 46 is used to realize aerial coordinate positioning and achieve aerial interaction. The interactive sensor 46 is located near the imaging lens 43, which facilitates timely information transmission and feedback. (Refer to...) Figure 5 Clicking the display command in the floating real image 44 allows you to control the height and / or rotation direction of the imaging device 4.

[0046] Optionally, refer to Figure 3 The imaging lens 43 can be an equivalent negative refractive lens, which may include two transparent substrates 431 and a first optical waveguide array 432 and a second optical waveguide array 433 disposed between the two transparent substrates 431. The first optical waveguide array 432 and the second optical waveguide array 433 are closely fitted together in a plane and orthogonally arranged. At the micrometer scale, a mutually orthogonal double-layer waveguide array structure is used to orthogonally decompose any optical signal. The original signal is projected onto the first optical waveguide array 432. A Cartesian coordinate system is established with the original signal projection point as the origin and the x-axis perpendicular to the first optical waveguide array 432 as the x-axis. Within this Cartesian coordinate system, the original signal is decomposed into two mutually orthogonal signals: signal X located on the x-axis and signal Y located on the y-axis. In this process, signal X undergoes total internal reflection at the same angle of reflection as the incident angle when it passes through the first optical waveguide array 432. Meanwhile, signal Y, remaining parallel to the first optical waveguide array 432, undergoes total internal reflection at the same angle of reflection as the incident angle on the surface of the second optical waveguide array 433. The reflected light signal, composed of signal Y and signal X, is mirror-symmetrical to the original light signal. Therefore, light rays from any direction can achieve mirror symmetry after passing through this equivalent negative refractive lens, and divergent light from any light source will converge again at symmetrical positions to form a floating real image 44.

[0047] At least one of the two transparent substrates 431 can be tempered glass. During installation, the tempered glass transparent substrate 431 is positioned on the side away from the center of the housing 41 to extend the service life of the imaging lens 43.

[0048] In practical use, when medical staff interpret images, they first adjust the height of the imaging device 4 using the height increase and decrease buttons on the floating real image 44; then, they adjust the left, right, and pitch angles of the imaging device 4 using the direction control buttons, making the floating real image 44 adaptable to the needs of medical staff. Medical staff use the floating real image 44 to perform business module operations, extracting useful information such as one-dimensional inspections, intraoperative X-rays, two-dimensional CT scans, and three-dimensional reconstructed digital models to assist in surgery. In other situations, medical staff other than the surgeon can manually adjust the device's posture, enriching the methods of use and expanding operational possibilities.
