Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a three-dimensional medical image display device. Background Art

[0002] With the continuous advancement of medical imaging technology, 3D models are playing an increasingly important role in surgical planning and navigation. High-precision 3D models enable doctors to more precisely locate lesions and plan surgical paths, thereby improving surgical success rates and safety. However, traditional 3D model viewing devices have some shortcomings in practical applications, especially in sterile environments and when multiple medical staff collaborate.

[0003] First, traditional 3D model viewing devices rely on contact-based human-computer interaction devices, such as mice, keyboards, data gloves, or tactile devices. These devices are prone to accumulating bacteria during use, increasing the risk of intraoperative infection. In an operating room, an environment with extremely high sterility requirements, any items that could become a source of contamination must be strictly controlled. Therefore, if doctors need to view or manipulate 3D models during surgery, they often need to do so indirectly, such as with the help of an assistant or using a dedicated sterile cover. This not only increases the complexity of the operation but also affects the consistency and efficiency of the surgical process.

[0004] Secondly, traditional 3D model display methods are usually limited to a single display screen, which means that only doctors in a specific position can clearly view the model. In multi-person collaborative surgical scenarios, this limitation may lead to poor information transmission and affect the efficiency of collaboration between team members. Although this problem can be alleviated by using mobile devices or multiple displays, these solutions often increase additional costs and space occupation, and still cannot fully meet the needs of all medical staff to view at the same time. In addition, even if the operation is performed by an assistant, there is still the problem of inefficient communication. Differences in knowledge structure, semantic understanding, etc. between different individuals may lead to misunderstandings or omissions of information, which in turn affects the accuracy and timeliness of surgical decisions.

[0005] To solve the above problems, there is an urgent need to provide a medical imaging three-dimensional display device that can display three-dimensional models without direct contact to reduce the risk of cross-infection, and can adapt to the needs of multiple people viewing at the same time to improve the collaboration efficiency of the surgical team. Utility Model Content

[0006] The utility model provides a three-dimensional medical image display device, which can display three-dimensional models without direct contact to reduce the risk of cross infection, and can adapt to the needs of multiple people viewing at the same time to improve the collaboration efficiency of the surgical team.

[0007] In order to achieve the above objectives, this application provides the following technical solutions:

[0008] A three-dimensional medical image display device includes a platform, a gesture sensor, a controller, and a display device; the top of the platform is provided with an integrally formed inverted "V"-shaped shelf; the display device includes a display screen and a projector, which are respectively arranged on either side of the inverted "V"-shaped shelf;

[0009] The gesture sensor and the display device are both electrically connected to the controller;

[0010] The gesture sensor detects gesture instructions and feeds back the gesture instructions to the controller;

[0011] The controller controls the display device to display the corresponding three-dimensional medical image according to the gesture instruction.

[0012] The principle and advantages of this utility model lie in the fact that an integrated inverted V-shaped shelf is incorporated into the platform, achieving an optimized layout for the display screen and projector. This design not only maximizes space utilization, but the inverted V-shaped structure also provides medical staff with an optimal viewing angle, facilitating intuitive viewing of 3D medical images on the display screen. Furthermore, the projector, positioned on the other side of the inverted V-shaped shelf, can project 3D medical images onto a wall or dedicated screen at a specific angle, further expanding the viewing range of the images.

[0013] By combining a dual display system with a monitor and projector, this solution ensures that both the surgeon directly in front of the device and team members in other areas of the operating room can clearly and intuitively view the required 3D medical images. This design greatly improves collaborative efficiency within the surgical team and facilitates synchronized information sharing and decision-making.

[0014] Furthermore, the integration of gesture sensors allows doctors to control the display device contactlessly through specific gestures, eliminating the risk of cross-infection associated with traditional contact-based operations. This feature is crucial for maintaining a sterile surgical environment and also improves operational convenience and responsiveness.

[0015] In summary, the three-dimensional medical imaging display device of this solution has the following significant advantages:

[0016] High degree of sterility: Contactless gesture control significantly reduces the risk of intraoperative infection and meets the strict sterility requirements of the medical environment.

[0017] Excellent visibility: The dual display system combining a display screen and a projector allows multiple people to view clear 3D medical images simultaneously from different angles, enhancing visual support for team collaboration.

[0018] Efficient interactivity: The fast and intuitive operation provided by gesture sensors reduces misunderstandings and delays caused by poor communication, and improves the efficiency and accuracy of surgical procedures.

[0019] Furthermore, a projector support plate is provided at the upper edge of one side of the inverted "V"-shaped storage rack, and the projector is arranged on the projector support plate.

[0020] Furthermore, a display screen support plate is provided at the bottom of the other side of the inverted "V"-shaped storage rack, and the display screen is arranged on the display screen support plate.

[0021] Furthermore, it also includes a light sensor, which is electrically connected to the controller;

[0022] The light sensor detects the ambient light intensity and feeds back a light intensity detection signal to the controller;

[0023] The controller controls the display brightness of the display device according to the light intensity detection signal.

[0024] Beneficial effects: The light sensor can accurately detect the ambient light intensity, ensuring that the display device displays three-dimensional medical images at the most appropriate brightness, whether in a dimly lit operating room or in a brightly lit environment, thereby providing a clear and comfortable viewing experience; by automatically adjusting the display brightness, it avoids visual fatigue caused by overly bright or dark screens, helping to protect the eyesight of medical staff, especially during long surgeries; reasonable brightness adjustment can reduce the power consumption and heat generation of the display device, thereby extending its service life and reducing maintenance costs.

[0025] Furthermore, the top of the platform is provided with a groove for placing the gesture sensor and a cover corresponding to the groove.

[0026] Beneficial Effect: The groove provides a fixed and secure location for the gesture sensor, preventing it from accidental collision or damage during operation. The cover further protects the gesture sensor from potential contaminants such as dust and liquids when not in use, ensuring long-term stable operation.

[0027] Furthermore, a positioning hole is provided at the bottom of the groove, a protrusion corresponding to the positioning hole is provided at the bottom of the gesture sensor, and the platform and the gesture sensor are connected via the positioning hole and the protrusion.

[0028] Beneficial effects: The cooperation between the positioning hole and the protrusion can realize the quick positioning and installation of the gesture sensor; the snap-on method can ensure a stable connection between the gesture sensor and the platform, preventing displacement or loosening during use, and ensuring the operational stability and reliability of the equipment.

[0029] Furthermore, rollers are provided at the bottom of the platform.

[0030] Beneficial effects: The rollers at the bottom of the table allow the entire device to be easily moved. Medical staff can push the display device to different operating rooms or work areas as needed, greatly improving the flexibility and convenience of the device. In emergency situations or when the device needs to be quickly adjusted, the rollers can respond quickly, saving time and energy in moving the equipment, thereby improving overall work efficiency.

[0031] Figure 1 The figure is a schematic diagram of the overall structure of an embodiment of a three-dimensional medical image display device of the present utility model.

[0032] Figure 2 The figure is a signal flow diagram of an embodiment of a three-dimensional medical image display device of the present invention. DETAILED DESCRIPTION

[0033] The following is further described in detail through specific implementation methods:

[0034] The symbols in the drawings of the specification include: platform 1, roller 2, light sensor 3, display screen 4, projector 5, inverted "V" shaped storage rack 6, display screen support plate 7, projector support plate 8, groove 9, and positioning hole 10.

[0035] Example 1:

[0036] Example 1 is basically as shown in the attached Figure 1 As shown:

[0037] A three-dimensional medical image display device includes a platform 1, a gesture sensor, a light sensor 3, a controller and a display device. Figure 1 As shown, the top of the platform 1 is provided with an integrally formed inverted "V"-shaped shelf 6; the display device includes a display screen 4 and a projector 5, which are respectively arranged on either side of the inverted "V"-shaped shelf 6. Specifically, a projector support plate 8 is provided at the upper edge of one side of the inverted "V"-shaped shelf 6, on which the projector 5 is mounted; a display screen support plate 7 is provided at the bottom of the other side, on which the display screen 4 is mounted. Both the projector support plate 8 and the display screen support plate 7 are provided with stoppers to prevent the projector 5 and display screen 4 placed thereon from sliding off.

[0038] The dual display system, combining display screen 4 and projector 5, ensures that both the surgeon directly in front of the device and team members in other areas of the operating room can clearly and intuitively view the required three-dimensional medical images. This design greatly improves the collaborative efficiency of the surgical team and facilitates synchronized information sharing and decision-making. Furthermore, the projector support plate 8 is positioned at the upper edge of one side of the inverted "V"-shaped shelf 6, providing a higher placement for the projector 5 and preventing other items in the operating room from obstructing the projection of the projector 5.

[0039] The top of the platform 1 is also provided with a groove 9 for placing the gesture sensor and a cover corresponding to the groove 9. Specifically, one end of the cover is hinged to the top of the platform 1 and is located directly above the groove 9. The cover is also provided with a handle, so that the cover can be rotated by pulling the handle on the cover. When the display device is not in use, the cover can be closed to protect the gesture sensor from potential contaminants such as dust and liquids during non-use periods.

[0040] The bottom of the groove 9 is provided with a positioning hole 10, and the bottom of the gesture sensor is provided with a protrusion corresponding to the positioning hole 10. The platform 1 and the gesture sensor are connected by means of the positioning hole 10 and the protrusion. Thus, the cooperation between the positioning hole 10 and the protrusion allows for quick positioning and installation of the gesture sensor. Furthermore, the clamping connection ensures a stable connection between the gesture sensor and the platform 1, preventing displacement or loosening during use, thereby ensuring the operational stability and reliability of the device.

[0041] like Figure 1 As shown, the bottom of the platform 1 is provided with rollers 2, which allow the entire device to be easily moved. Medical staff can push the display device to different operating rooms or work areas as needed, greatly improving the flexibility and convenience of the device. In emergency situations or when the device needs to be quickly adjusted, the rollers 2 can achieve a quick response, saving time and energy in moving the device, thereby improving overall work efficiency. Specifically, the rollers 2 can be universal wheels, making the display device more flexible to move.

[0042] like Figure 2As shown, the gesture sensor, light sensor 3, and display device are all electrically connected to the controller. In this embodiment, the gesture sensor uses a Leap Motion controller, which has a recognition accuracy of up to 0.01 mm and can accurately capture information about all ten fingers. The user's fingers can move within the Leap Motion controller's recognition area, which captures the finger information within that area. During use, medical personnel only need to make corresponding gestures within the recognition area at the top of the Leap Motion controller to quickly access the corresponding three-dimensional medical image for display. The light sensor 3 is model BH1750FVI; the display screen 4 is an LED display screen 4; the projector 5 is a Z7X ultra-thin projector 5; and the controller model is S7-1200.

[0043] The gesture sensor is used to detect gesture instructions and feed them back to the controller. The light sensor 3 is used to detect ambient light intensity and feed back a light intensity detection signal to the controller. The controller is used to control the display device to display the corresponding three-dimensional medical image based on the gesture instructions. Specifically, the controller stores a number of gesture instructions and corresponding three-dimensional medical images. After obtaining the gesture instructions from the gesture sensor, the controller calls the corresponding three-dimensional medical image based on the gesture instructions and controls the display screen 4 and projector 5 to display them. The controller is also used to control the display brightness of the display device based on the light intensity detection signal. Specifically, the brightness of the projector 5 and the display screen 4 is divided into three levels from low to high, namely, level 1, level 2, and level 3. The initial brightness of both is level 2. If the light intensity detection signal indicates that the ambient light intensity is less than the dark light threshold, the projector 5 and the display screen 4 are controlled to adjust the display brightness to level 1. If the light intensity detection signal indicates that the ambient light intensity is greater than the bright light threshold, the projector 5 and the display screen 4 are controlled to adjust the display brightness to level 3. If the light intensity detection signal indicates that the ambient light intensity is greater than or equal to the dark light threshold and less than or equal to the bright light threshold, the projector 5 and the display screen 4 are controlled to maintain the display brightness adjusted to level 2.

[0044] As a result, whether in a dimly lit operating room or a brightly lit environment, the display device can display three-dimensional medical images at the most appropriate brightness, providing a clear and comfortable viewing experience. By automatically adjusting the display brightness, visual fatigue caused by an overly bright or dark screen can be avoided, helping to protect the eyesight of medical staff, especially during long surgeries. In addition, reasonable brightness adjustment can reduce the power consumption and heat generation of the display device, thereby extending its service life and reducing maintenance costs.

[0045] Example 2:

[0046] The basic principles of Example 2 are the same as those of Example 1, with the difference being that in Example 2, the three-dimensional medical images stored in the controller are personalized three-dimensional medical images generated by three-dimensional modeling based on the patient's CT scan data; the three-dimensional medical images include organ structures with adjustable transparency. The display device also includes an endoscope electrically connected to the controller. The endoscope is used to acquire patient images and feed back image signals to the controller. After the controller controls the display device to display the corresponding three-dimensional medical image, it analyzes the real-time position of the endoscope based on the image signals fed back by the endoscope and controls the display device to display the real-time position of the endoscope. The endoscope is selected based on the surgical requirements and can be a gastroscope, colonoscope, bronchoscope, etc.

[0047] By adopting this solution, the medical image three-dimensional display device can not only provide static personalized three-dimensional medical images, but also realize dynamic endoscope position tracking, further improving the surgical accuracy and safety.
