Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a head-mounted interactive medical image display device. Background Technology

[0002] With the development of medical imaging technology, modalities such as MRI, CT, and PET can generate high-resolution three-dimensional volumetric data. Doctors are increasingly relying on multi-angle, multi-level observation of this three-dimensional data in clinical diagnosis. Traditional two-dimensional slice browsing methods are no longer sufficient to meet the needs of locating complex lesions, surgical planning, and teaching demonstrations.

[0003] In current medical settings, medical images (such as CT, MRI, and ultrasound images) are the core basis for medical personnel to diagnose conditions and formulate surgical plans. However, existing methods of displaying and interacting with medical images have certain problems. On the one hand, traditional display devices (such as medical monitors and surgical navigation screens) are mostly fixed installations. During operation, medical personnel need to frequently look down to view images and look up to operate, resulting in frequent switching of gaze. This not only increases neck fatigue but may also reduce operational efficiency due to interruptions in vision and even cause the omission of key image details. On the other hand, the frames of some head-mounted display devices are mostly of fixed size or have only one adjustable tightness, which cannot adapt to different head circumferences. This can easily lead to problems such as looseness for those with smaller head circumferences and pressure on the head for those with larger head circumferences. Especially during surgery, when the head is turned or the operator is bent over, the device is prone to slipping or shifting. Therefore, we urgently need a head-mounted interactive medical image display device to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a head-mounted interactive medical imaging display device. Through a slide bar-sleeve adjustment structure, multi-segment damped connecting rods, and ear-mounted support legs, it can adapt to different head circumferences, prevent the device from slipping or shifting, ensure stable image display, and at the same time buffer wearing pressure, thereby improving the adaptability and comfort of use in medical scenarios.

[0005] According to a first aspect of the present invention, a head-mounted interactive medical imaging display device is provided, comprising a host for displaying images, and a rectangular sleeve disposed above the host. A slide rod is slidably connected inside the rectangular sleeve, and the end of the slide rod is hinged to the upper part of the host. When the slide rod moves, it is locked by an upper limit member of the rectangular sleeve to form an installation area. A support part for supporting the host is provided on the rectangular sleeve.

[0006] Optionally, the limiting component includes a limiting groove formed on the slide rod, and the upper part of the rectangular sleeve is threaded with a limiting pin for positioning the slide rod. When the end of the limiting pin abuts against the inner wall of the limiting groove, a positioning area is formed.

[0007] Optionally, the support includes a connecting plate threaded to the lower part of the rectangular sleeve, the connecting plate being covered with a second soft pad for abutting against the head.

[0008] Optionally, a first connecting rod is hinged to the rectangular sleeve, a second connecting rod is hinged to the connection of the first connecting rod, and a third connecting rod is hinged to the connection of the second connecting rod.

[0009] Optionally, the end of the third connecting rod is hinged to an arc-shaped plate, which is covered with a third soft pad for abutting against the neck.

[0010] Optionally, the host is symmetrically and movably equipped with support legs for hanging ears, and a fourth soft pad is fixedly installed on the opposite sides of both sets of support legs.

[0011] Optionally, the main unit is hinged with a snap-on cover for dust protection.

[0012] Optionally, a fifth soft pad that fits around the eyes is fixedly installed on the main unit.

[0013] Optionally, the fourth cushion is made of sponge.

[0014] Optionally, the fifth pad is made of silicone.

[0015] 1. According to one embodiment of this disclosure, the head-mounted interactive medical imaging display device can flexibly adjust the front-to-back distance between the device and the head through the sliding cooperation of a rectangular sleeve and a slide rod, adapting to common head circumferences of 54-62cm, avoiding the problem of looseness for those with smaller head circumferences and pressure on the head for those with larger head circumferences; at the same time, the damping at the hinge of the slide rod and the main body of the device can instantly fix the adjusted pitch angle, and with the mechanical locking of the upper limit pin of the rectangular sleeve and the limiting groove of the slide rod, it can prevent the device from shifting angle or sliding position due to head movement during medical operations, ensuring stable display position and reducing the interference of frequent adjustments on the diagnosis and treatment process.

[0016] 2. According to one embodiment of this disclosure, the head-mounted interactive medical imaging display device, through the multi-segment hinge design of the first to third connecting rods, can flexibly adjust its length and angle to adapt to different postures such as upright consultation and bent-over surgery. The damping at each hinge can be locked to prevent the connecting rods from sagging. Combined with the ergonomic contour of the arc-shaped plate at the end of the third connecting rod and the anti-slip properties of the third soft pad, the arc-shaped plate can fit closely to the back of the neck, converting the downward force of the device into a supporting reaction force. Combined with the side ear fixing of the support leg and the pressure cushioning of the fourth soft pad, a triangular stability system is formed, which not only completely prevents the device from slipping and shifting, but also reduces the wearing pressure pain in the ears and neck, and improves the comfort of long-term use.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0025] like Figure 1-5 As shown, a head-mounted interactive medical imaging display device includes a host 1 for displaying images.

[0026] To achieve efficient image display and multimodal interaction, host 1 incorporates the following hardware modules to ensure performance meets standards, including: S1. High-resolution display module: Equipped with a near-eye display screen with a resolution of no less than 3840×2160 and a pixel density of ≥300PPI, ensuring that the fine structures of CT / MRI images are clearly presented.

[0027] S2, Multi-touch Interaction Module: The main unit 1 display surface integrates a 10-point touch panel, which supports zooming, such as zooming in on images to view details, rotation, such as adjusting the perspective of anatomical structures, sliding, such as switching image sequences, etc. This operation requires an external peripheral device.

[0028] S3, Graphics Rendering Module: Built-in WebGL rendering engine, relying on GPU hardware acceleration to realize real-time rendering and dynamic updating of 3D medical images, avoiding image lag and meeting the needs of real-time observation during surgery.

[0029] S4. Wireless Communication Module: Integrates Bluetooth 5.0 and Wi-Fi 6 modules. Bluetooth is used to connect to external gesture recognition cameras, such as LeapMotion or wireless mice, while Wi-Fi is used to establish connections with hospital PACS systems and external VR headsets to achieve image data synchronization and dual-channel display.

[0030] S5, Attitude Sensing Module: Embedded with a gyroscope attitude sensor, it can detect changes in the spatial attitude of the host 1, such as the head rotation of medical personnel, and automatically adjust the image display angle to ensure that the line of sight is always synchronized with the image.

[0031] S6. Data Interconnection Module: Supports DICOM 3.0 standard interface, can directly connect to PACS system to obtain raw CT / MRI scan data without additional conversion equipment, realizing the integration of "data acquisition - 3D reconstruction - display interaction".

[0032] S7. Quick Operation Module: The main unit 1 has 3 dedicated physical buttons on the side, which are used to quickly switch preset views, such as the long axis of the heart, the brainstem section, start measurement tools, such as lesion diameter measurement, and mark key areas, such as tumor location, to reduce operation steps.

[0033] It is worth noting that the illustrations in the instruction manual showing the main unit 1 are for illustrative purposes only, and the physical buttons and other components in the built-in modules are not shown.

[0034] Furthermore, as the VR glasses integrating core hardware, Host 1's hardware is fully adapted to the VR interaction needs of medical imaging. The 4K high-resolution VR display can present 3D images of CT / MRI in a near-eye immersive manner, allowing medical personnel to intuitively observe anatomical structures, such as the spatial relationship between tumors and blood vessels; the WebGL rendering engine, relying on GPU acceleration, ensures real-time dynamic updates of VR images without lag or delay, meeting the real-time navigation needs during surgery; the Bluetooth / Wi-Fi module can connect to external gesture recognition devices, allowing medical personnel to control the images in VR without touching the VR glasses, reducing the risk of cross-infection; the gyroscope sensor, combined with VR head tracking, allows the VR image perspective to switch synchronously when the medical personnel turn their heads, achieving a natural "line of sight as perspective" interaction without manual adjustment; the DICOM interface directly connects to the PACS system, allowing the VR glasses to quickly acquire and reconstruct 3D images without relying on external workstations, adapting to mobile scenarios such as bedside and operating rooms; the medical antibacterial shell ensures that the VR glasses can withstand alcohol disinfection, meeting medical sterility requirements.

[0035] The main unit 1 is symmetrically and movably equipped with support legs 13 for hanging ears. The opposite sides of the two sets of support legs 13 are fixedly equipped with fourth soft pads 14. The main unit 1 is hinged with a snap-fit ​​cover 15 for dust protection. The main unit 1 is fixedly equipped with a fifth soft pad 16 that fits around the eyes.

[0036] Here, the symmetrically installed support legs 13 provide a three-point fixation system for the device, consisting of lateral fixation, top support, and neck support, significantly improving overall stability. The support legs 13 are made of elastic resin material, which can be slightly bent according to the shape of the ear to ensure a fit to the contours of different sized ears; the fourth soft pad 14 on the opposite side is made of thin sponge material, which can cushion the pressure of the support legs 13 on the ear and avoid pressure marks or pain on the ear after wearing it for a long time. In addition, the ear-hook design can prevent the main unit 1 from wobbling back and forth. When the medical staff turns their head to check the surgical area and then turns back, the main unit 1 can still stay in front of the eyes without the need to readjust the field of vision, improving the continuity of operation.

[0037] Furthermore, the snap-on cover 15 can completely cover the VR lens and display area, preventing dust from adhering to the surface of the VR lens when idle. VR lenses require high-precision optical performance, and dust can cause a decrease in image transmittance and the appearance of light spots, affecting the observation effect. The damping at the hinge of the snap-on cover 15 is only used to assist in opening and closing, preventing the cover from slipping off by itself. This ensures both dust prevention and ease of operation, and does not affect the normal wearing and use of VR glasses when opened.

[0038] Furthermore, the fifth soft pad 16 conforms to the eye area to form a sealed space. On the one hand, it blocks external light, such as surgical lights, from entering, preventing light from interfering with the immersion and clarity of the VR image, ensuring that medical personnel can focus on the 3D medical images in VR. On the other hand, the soft pad can cushion the pressure of the VR glasses edge on the skin around the eyes. Combined with the weight support structure of the VR glasses, it reduces discomfort around the eyes after wearing for a long time, while maintaining the airtightness of the VR display to avoid image observation deviations caused by light leakage. In addition, the fifth soft pad 16 is made of medical-grade non-toxic silicone, which is non-irritating to the skin. Even if it is in contact with the eye area for a long time, it will not cause skin discomfort, thus balancing visual effect and wearing safety.

[0039] It also includes a rectangular sleeve 2 located above the main unit 1. A slide rod 3 is slidably connected inside the rectangular sleeve 2. The end of the slide rod 3 is hinged to the upper connection of the main unit 1. When the slide rod 3 moves, it is locked by the upper limit member of the rectangular sleeve 2 to form an installation area. The limit member includes a limit groove 4 opened on the slide rod 3. A limit pin 5 for positioning the slide rod 3 is threadedly connected to the upper part of the rectangular sleeve 2. When the end of the limit pin 5 abuts against the inner wall of the limit groove 4, a positioning area is formed.

[0040] Here, the rectangular sleeve 2 and the slider 3 serve as the top support and adjustment structure for the VR glasses. The sliding hinge design can adapt to the wearing position of the VR glasses for different head circumferences. The slider 3 slides along the sleeve to adjust the front-to-back distance between the VR glasses and the head, ensuring that the center of the VR lens is aligned with the pupil and avoiding field of vision shift. The damping at the hinge can fix the adjusted angle, preventing the VR glasses from rotating on their own due to head movements, such as when the head is tilted down during surgery, thus maintaining the stability of the near-eye display field of vision. At the same time, the slow adjustment provided by the damping can help medical personnel accurately find the optimal wearing position for the VR, avoiding dizziness caused by rapid adjustments.

[0041] Furthermore, damping is provided at the hinge between the slide bar 3 and the upper part of the main unit 1, which allows for immediate fixation after angle adjustment. When medical personnel adjust the display angle of the main unit 1, such as slightly raising it to avoid surgical instruments, the damping can counteract the weight of the main unit 1 itself, preventing the angle from shifting on its own without the need for additional locking operations. At the same time, the slow adjustment provided by the damping can prevent sudden changes in the field of view caused by excessively rapid angle adjustments, helping medical personnel to smoothly find the best observation angle and improving operational safety.

[0042] Furthermore, the limiting groove 4 on the slide bar 3 features a multi-position design, allowing precise control over the extension length of the slide bar 3. Combined with the threaded limiting pin 5 on the rectangular sleeve 2, the rear end of the pin is tightened to abut against the inner wall of the limiting groove 4, firmly locking the slide bar 3 in place. In scenarios requiring prolonged stable operation, such as surgery, even with frequent head movements and bending over by medical personnel, the slide bar 3 will not shift, preventing the main unit 1 from shifting and causing the image to leave the field of vision. This ensures the consistency of the image display position during diagnosis and treatment, reducing operational risks caused by device loosening.

[0043] The rectangular sleeve 2 is provided with a support part for supporting the main unit 1. The support part includes a connecting plate 6 threaded to the lower part of the rectangular sleeve 2. The connecting plate 6 is covered with a second soft pad 7 for abutting against the head. A first connecting rod 8 is hinged to the rectangular sleeve 2. A second connecting rod 9 is hinged to the connection of the first connecting rod 8. A third connecting rod 10 is hinged to the connection of the second connecting rod 9. An arc plate 11 is hinged to the end of the third connecting rod 10. A third soft pad 12 for abutting against the neck is covered on the arc plate 11.

[0044] Here, the connecting plate 6 is fixed to the rectangular sleeve 2 by a threaded connection, which not only ensures a secure assembly but also allows for fine-tuning of the height by rotation to accommodate the vertical head dimensions of different medical personnel. The second soft pad 7, which covers the connecting plate 6, is made of medical-grade memory foam, which has excellent softness and resilience. It can make even contact with the top side of the head, distributing the weight of the device over a larger area and avoiding localized pressure concentration. Even if medical personnel wear it continuously for 2 to 3 hours during surgery or consultation, they will not experience pressure pain on the top side of their head, greatly improving the comfort of wearing it for a long time.

[0045] Furthermore, the three connecting rods can be flexibly hinged 360°, allowing for free adjustment of angle and length according to the neck curve and shoulder height of the medical personnel, forming a support link from the rectangular sleeve 2 to the back of the neck. For example, when the medical personnel are bending over to perform surgical procedures, the connecting rods can be bent to allow the subsequent curved plate 11 to fit tightly against the back of the neck, forming an upward support force to counteract the downward tendency of the main unit 1. This completely solves the problem of existing head-mounted devices easily slipping when bending over, ensuring that the device can be stably fixed in various operating postures.

[0046] It is important to note that the damping at the hinge joints between the three connecting rods can solve the problem of easy loosening of the support structure. When adjusting the angle of the connecting rods, for example to adapt to different neck curvatures, the damping can keep each connecting rod in any adjustable position and prevent it from automatically drooping due to gravity. Even if the medical staff's head shakes slightly during surgery, the damping can also buffer the external force and prevent the connecting rods from causing the arc plate 11 to shift, ensuring the stability of the neck support and further preventing the main unit 1 from sliding down.

[0047] Furthermore, the curved plate 11 conforms to the back of the neck, providing downward support for the VR glasses. The damping at the hinge fixes the tilt angle of the curved plate 11, adapting to different neck curves, such as short and long necks, ensuring that the support point is always in close contact without pressure. At the same time, the damping reduces the relative sliding between the curved plate 11 and the neck, preventing the VR glasses from slipping due to body movement, further ensuring the stability of the VR near-eye display, allowing medical personnel to focus on the image and operation. The third soft pad 12 is made of medical-grade silicone, which is not only soft and skin-friendly but also has anti-slip properties, increasing friction with the neck skin and further preventing device displacement. In addition, the silicone material is resistant to alcohol wiping, allowing for rapid disinfection after surgery, meeting the sterile requirements of medical scenarios, and balancing practicality and hygiene standards.

[0048] In this invention, before use, the main unit 1 connects to the hospital's PACS system via a Wi-Fi module to obtain raw CT / MRI data. After transmission via a DICOM interface, the WebGL rendering engine, relying on the GPU, completes the 3D image reconstruction. Simultaneously, it can pair with a gesture recognition camera via Bluetooth and preset commonly used medical views using a dedicated physical button as needed. It also pushes the slide bar 3 inside the rectangular sleeve 2 to initially adapt to the head circumference and bends the support leg 13 to fit the ear shape. When wearing it, first place the main unit 1 close to the face so that the fifth soft pad 16 fits around the eyes, hang the support leg 13 on the ear using the fourth soft pad 14 for cushioning and anti-slip, then finely adjust the hinge angle between the slide bar 3 and the main unit 1, and twist the limiting pin 5 to embed it into the limiting groove 4 of the slide bar 3 to lock the top position. Then, bend the first connecting rod 8, the second connecting rod 9, and the third connecting rod 10 so that the arc plate 11 fits the back of the neck via the third soft pad 12. The downward force of the device 1 is converted into a supporting reaction force, which, together with the top slide bar 3 and the side support leg 13, forms a triangular stability system. An optional rotating connecting plate 6 allows the second soft pad 7 to fit against the top side of the head for auxiliary fixation. During image display, the 4K UHD display screen presents a three-dimensional image to ensure the clarity of fine structures. The fifth soft pad 16 isolates external light to avoid reflection. It can also synchronize images to an external VR headset via Wi-Fi to achieve dual-channel display. During interactive operation, the gyroscope attitude sensor adjusts the image perspective synchronously with the head rotation. The touch panel supports zoom / rotate / swipe operations. The gesture recognition camera transmits action commands via Bluetooth. A dedicated physical button can switch views, start measurement, or mark lesions with one click. An optional image registration algorithm aligns images of different modalities. After use, the flip-up and snap-on cover 15 covers the main unit 1 for dust protection. The medical antibacterial material shell is used for alcohol wiping and disinfection, adapting to the needs of medical scenarios.
