[0002] Currently, doctors review medical images such as CT and MRI scans during surgery or rounds via large-screen monitors fixed to the walls of the reading room or operating room. This requires doctors to move between the operating table and the display terminal, making it impossible to access the images in real-time near the patient. Traditional physical films lack interactivity, preventing operations such as rotation, zooming, and 3D reconstruction. Using touchscreen terminals for image review requires doctors to remove gloves, posing a sterile risk. Furthermore, some VR / AR headsets require specialized glasses, which present problems such as limited field of view, bulky equipment, and high adaptation costs for doctors. Summary of the Invention

Therefore, they should not be construed as limitations on this invention.

[0018] In the description of this invention, "first feature" and "second feature" may include one or more of the features.

[0019] In the description of this invention, "a plurality of" means two or more.

[0020] The non-contact holographic surgical image reading terminal 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0021] like Figures 1-6 As shown, the non-contact holographic surgical image reading terminal 1 according to an embodiment of the present invention includes: a trolley body 100 and an interactive module 200, which is installed on the trolley body 100.

[0022] The interactive module 200 includes: an interactive control unit 210, a module housing 220, an imaging lens 230, an imaging screen 240, and an interactive sensor 250.

[0023] The interactive control unit 210 is adapted to communicate with the terminal controller 10. A receiving cavity is formed within the module housing 220, and a glass frame 221 is constructed on its top. An imaging lens 230 is mounted on the top surface of the module housing 220 and fixed by the glass frame 221. An imaging screen 240 is mounted within the module housing 220. The image light from the imaging screen 240 passes through the imaging lens 230, forming a floating real image 201 above the imaging lens 230 that is mirror-symmetrical to the imaging screen 240. A downwardly extending sensor mounting slot 21 is constructed on one side of the module housing 220. The sensor mounting slot 21 is located at the bottom edge of the imaging lens 230. An interactive sensor 250 is detachably mounted in the sensor mounting slot 21 and enclosed by the glass frame 221. The interactive sensor 250 detects air gestures in the area of ​​the floating real image 201 and interacts with the interactive control unit 210.

[0024] For example, when it is necessary to access a patient's CT, MRI, or other medical images during surgery, this terminal can be directly pushed to the side of the operating table, eliminating the need to travel between the operating table and the fixed image viewing terminal, allowing the image viewing operation to be completed next to the patient. Operations are performed via air gestures in the floating real image 201 area. The interactive sensor 250 captures the gesture signals in real time and transmits them to the interactive control unit 210. The interactive control unit 210 transmits the action commands to the terminal controller 10, completing interactive operations such as rotating, zooming, and 3D reconstruction of the medical images. Throughout the entire operation, the doctor does not need to remove sterile gloves or touch the physical control panel, effectively avoiding the risk of cross-infection and meeting the sterility requirements of the surgical scenario.

[0025] According to an embodiment of the non-contact holographic surgical image reading terminal 1 of the present invention, a downwardly extending sensor mounting slot 21 is constructed on one side of the module housing 220. An interactive sensor 250 is detachably mounted in the sensor mounting slot 21. The area detected by the interactive sensor 250 coincides with the area of ​​the floating real image 201, enabling accurate recognition of gestures applied to the floating real image 201. This avoids operational misjudgments caused by misalignment between the gesture recognition area and the imaging area, improving the accuracy of gesture interaction. The downwardly extending sensor mounting slot 21 matches the detection orientation of the interactive sensor 250 with the area of ​​the floating real image 201. Simultaneously, the glass frame 221 provides a sealed protection for the sensor, without occupying additional external space or compromising the overall integrity of the device's shape, resulting in a more compact and rational structural arrangement.

[0026] Among them, such as Figure 5 and Figure 6 As shown, the imaging lens 230 is an equivalent negative refractive index planar lens, comprising a first transparent protective layer 11, a first optical waveguide array 12, a second optical waveguide array 13, and a second transparent protective layer 14, sequentially stacked along the thickness direction. The first optical waveguide array 12 includes multiple optical waveguides arranged parallel to a first direction, and the second optical waveguide array 13 includes multiple optical waveguides arranged parallel to a second direction. The first and second directions are perpendicular to each other, meaning that from the thickness direction of the imaging lens 230, the first optical waveguide array 12 and the second optical waveguide array 13 are orthogonally arranged. Each optical waveguide includes a reflective element and a reflective film deposited on the side of the reflective element. The reflective film is used to cause total internal reflection of the incident light at a reflection angle equal to the incident angle. After the image light emitted from the imaging screen 240 is incident on the imaging lens 230, it is decomposed at the micrometer scale by the orthogonally arranged double-layer optical waveguide array into two mutually orthogonal beam components diverging along the first and second directions. A beam component diverging along the second direction is incident perpendicularly onto multiple optical waveguides of the first optical waveguide array 12, and after being reflected sequentially by the reflective film, passes through the second optical waveguide array 13. A beam component diverging along the first direction passes parallel to the first optical waveguide array 12 and is then reflected sequentially by multiple optical waveguides of the second optical waveguide array 13. The two orthogonal beam components reconverge on the exit side of the imaging lens 230, thereby forming a floating real image 201 on the side of the imaging lens 230 away from the imaging screen 240.

[0027] The sensor mounting slot 21 is located at the bottom edge of the imaging lens 230. That is, the lower edge of the glass frame 221 covers the opening of the sensor mounting slot 21, making the interactive sensor 250 invisible from the outside, but its detection field of view is not obstructed by the glass frame 221. The interactive sensor 250 detects air gestures in the area of ​​the floating real image 201 along the inclined direction of the sensor mounting slot 21. The gesture signals collected by the interactive sensor 250 are transmitted to the terminal controller 10 for analysis and execution.

[0028] Therefore, the non-contact holographic surgical image reading terminal 1 according to the present invention has advantages such as reduced infection risk, small space occupation, and convenient operation.

[0029] In some specific embodiments of the present invention, such as Figures 2-4 As shown, the module housing 220 includes: housing body 222 and inner frame 223. The cross-section of the inner frame 223 is constructed into a triangle, and the imaging screen 240 is disposed on the surface where one side of the bottom of the triangle is located.

[0030] The image light emitted from the imaging screen 240 ensures that it can pass smoothly through the glass frame 221 to reach the imaging lens 230 without obstructing the imaging process, thus guaranteeing the clarity of the floating real image 201. Simultaneously, the tempered glass possesses high structural strength, capable of withstanding scratches and a certain degree of external impact during daily use, and is not prone to breakage or deformation, improving the overall structural stability and lifespan of the device. The triangular inner frame 223 provides a support base for the inclined installation of the imaging screen 240. Furthermore, the triangular structure has high structural rigidity, maintaining the relative position of the imaging screen 240 and the imaging lens 230 stable under vehicle vibration conditions, preventing optical path deviation that could cause blurring or displacement of the floating real image 201.

[0031] Furthermore, the cross-section of the inner frame 223 is constructed as a right-angled triangle, with the plane containing the imaging screen 240 forming a 45° angle with the plane containing the imaging lens 230. This 45° angle, combined with the inclined support surface of the triangular inner frame 223, allows the image light emitted from the imaging screen 240 to be projected onto the imaging lens 230 at a predetermined incident angle. After beam expansion by the lens, a clear floating real image 201 is formed above the imaging lens 230. By arranging the imaging screen 240 at a 45° angle, the optical path is folded and stored, keeping the overall thickness of the interactive module 200 within 210mm, thus meeting the deployment requirements of narrow spaces such as operating rooms.

[0032] Furthermore, such as Figure 3 As shown, the back side of the imaging screen 240 has an angle adjustment bracket 241, which is installed in the receiving cavity and is used to adjust the angle between the imaging screen 240 and the imaging lens 230.

[0033] The imaging screen 240 has an angle adjustment bracket 241 on its back side, which is installed within the receiving cavity. The angle adjustment bracket 241 is used to adjust the angle between the imaging screen 240 and the imaging lens 230. During assembly, the tilt angle of the angle adjustment bracket 241 is adjusted using an optical path calibration fixture to ensure that the center of the effective display area of ​​the imaging screen 240 coincides with the center of the light-emitting surface of the imaging lens 230, and to ensure that the optical distance between the light-emitting surface of the imaging screen 240 and the imaging lens 230 meets the imaging sharpness requirements. After calibration, the angle adjustment bracket 241 is locked and fixed.

[0034] In some specific embodiments of the present invention, such as Figure 4 As shown, the non-contact holographic surgical image reading terminal 1 also includes a mounting base plate 224, which is fixed to one side of the trolley body 100 and supported on the bottom of the interactive module 200.

[0035] The terminal also includes a mounting base plate 224. The mounting base plate 224 is fixed to the upper part of the trolley body 100 and supports the bottom of the interactive module 200. The mounting holes of the mounting base plate 224 correspond one-to-one with the connection holes on the upper part of the trolley body 100. After fixing the mounting base plate 224 to the trolley body 100 with bolts, the interactive module 200 is placed on the mounting base plate 224 and locked in place through the pre-drilled threaded holes in the base plate, thus achieving a detachable connection between the interactive module 200 and the trolley body 100. Furthermore, the mounting base plate 224 provides a certain degree of support, ensuring the stability of the interactive module 200 and the floating real image 201.

[0036] Furthermore, such as Figure 4 As shown, the terminal controller 10 is installed on the mounting base 224 and housed between the housing body 222 and the inner frame 223.

[0037] The terminal controller 10 is electrically connected to the interactive control unit 210, the imaging screen 240, and the auxiliary display 300, respectively, and is responsible for running the medical image processing software, parsing gesture commands, and driving the display output. The terminal controller 10 is placed in the unused space between the main body 222 and the inner frame 223, which makes full use of the internal space of the interactive module 200 and facilitates maintenance of the terminal controller 10 by disassembling the upper shell of the module housing 220.

[0038] In some specific embodiments of the present invention, such as Figure 1 As shown, the trolley body 100 includes: a base 110, a lifting rod 120 and casters 130. The casters 130 are located at the bottom of the base 110. One end of the lifting rod 120 is connected to the base 110 and the other end is fixedly connected to the module box 220.

[0039] Casters 130 are located at the four bottom corners of the base 110. The lifting rod 120 is an electric lifting rod, which is fixedly connected to the base 110 and the module housing 220 respectively, with a lifting stroke ranging from 795mm to 1145mm. The extension and retraction of the lifting rod 120 directly drives the interactive module 200 to move up and down, thereby adjusting the display height of the floating real image 201 to adapt to different usage scenarios such as doctors operating in a standing posture (approximately 1100mm) and nurses recording in a seated posture (approximately 850mm).

[0040] Furthermore, the non-contact holographic surgical image reading terminal 1 also includes a battery module (not shown in the figure). The battery module is integrated into the base 110, such as... Figure 4 As shown, the mounting base plate 224 is equipped with a step-down module 20, and the battery module supplies power to the imaging screen 240, the interactive sensor 250 and the interactive control unit 210 through the step-down module 20.

[0041] The built-in battery module allows the entire unit to operate independently without an external power source, facilitating flexible deployment in different operating rooms, wards, or exhibition venues. The step-down module 20 converts the battery output voltage into the operating voltage required by each electrical component, ensuring power supply stability.

[0042] In some specific embodiments of the present invention, such as Figure 4 As shown, the mounting base plate 224 is equipped with a switch button 226 and a lifting button 225. The switch button 226 is used to control the power supply of the whole machine, and the lifting button 225 is electrically connected to the lifting rod 120 to control its lifting action.

[0043] After pressing the switch button 226, the terminal controller 10 is activated, the imaging screen 240 and the auxiliary display 300 light up, and the system enters the standby interface. The lifting button 225 is electrically connected to the lifting rod 120. By pressing the lifting button 225, the extension or retraction of the lifting rod 120 is controlled, thereby adjusting the height of the interactive module 200 and the floating real image 201.

[0044] In some specific embodiments of the present invention, such as Figure 1 As shown, the non-contact holographic surgical image reading terminal 1 also includes an auxiliary display 300 and a display bracket 310. The display bracket 310 is installed on the trolley body 100, and the auxiliary display 300 is connected to the trolley body 100 through the display bracket 310. The auxiliary display 300 is communicatively connected to the terminal controller 10.

[0045] The monitor bracket 310 is mounted on the upright of the cart body 100, and the auxiliary monitor 300 is connected to the cart body 100 via the monitor bracket 310. The monitor bracket 310 is a single-joint support arm, capable of tilting from -15° to +30° and rotating 180° horizontally. The auxiliary monitor 300 communicates with the terminal controller 10 and supports one-button switching between mirror mode and extended mode: in extended mode, the imaging screen 240 displays the operation menu and 3D images for close-range interaction by the operator, while the auxiliary monitor 300 displays patient information and image data for remote viewing by the team; in mirror mode, the auxiliary monitor 300 synchronously displays all the content of the imaging screen 240, suitable for teaching and demonstration scenarios.
