Description

Technical Field

[0001] This invention relates to the field of operating table technology, specifically to an electronic display system for an angle-adjustable operating table. Background Technology

[0002] The operating table is a crucial piece of equipment in a hospital operating room, directly impacting surgical outcomes. Traditional operating tables are mostly designed with a fixed angle. However, some clinical studies and surgeries require observing the effects of different angles and positions on patients' perioperative vital signs, surgical outcomes, ease of operation, and adverse reactions. For example, spinal surgery, craniocerebral surgery, cardiac surgery, laparoscopic surgery, and robot-assisted surgery all require different angles and positions. This necessitates that the operating table have precise and convenient angle adjustment capabilities.

[0003] However, when the operating table is adjusted, the angle of the display system installed on the table, i.e. the display screen, will move synchronously. This results in the adjusted angle of the display screen being incompatible with the posture and field of vision of the medical staff performing the surgery. For example, the medical staff may have difficulty seeing the content displayed on the screen, but once the medical staff adjusts the angle of the display screen, it may affect the progress of the surgery.

[0004] Therefore, the present invention provides an electronic display system for an angle-adjustable operating table, which enables the display screen to adjust automatically, reducing surgical risks and improving patient safety. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an electronic display system for an angle-adjustable operating table. A second adjustment component is installed inside the base, comprising a second motor located at the bottom of the base, a push rod positioned above the second motor, and the top of the push rod hinged to the bottom of an adjustment plate. A linkage is provided between the second motor and the push rod. After the second motor outputs power, the linkage causes the push rod to rotate the adjustment plate along the edge of the base. A first adjustment component is positioned between the display screen and the adjustment plate, and the second adjustment component allows the display screen to slide up and down along the surface of the adjustment plate. This system adapts the current position of the display screen to the head position of the medical staff, ensuring that the medical staff can always observe the surface of the display screen and not miss the information displayed, thus improving the convenience of the display screen and solving the problems in the prior art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: an electronic display system for an angle-adjustable operating table, comprising a display system body, the display system body including a vertically arranged and hollow base, a display screen disposed on one side of the base, and an adjustment plate hinged to the top edge of the base near the display screen, the display screen and the adjustment plate being detachably fixed; a second adjustment assembly is disposed inside the base, the second adjustment assembly including a second motor located at the bottom of the base, a push rod disposed above the second motor, the top end of the push rod being hinged to the bottom of the adjustment plate, a linkage is disposed between the second motor and the push rod, after the second motor outputs power, the linkage causes the push rod to push the adjustment plate to rotate along the edge of the base; a first adjustment assembly is disposed between the display screen and the adjustment plate, and the second adjustment assembly causes the display screen to slide up and down along the surface of the adjustment plate;

[0009] It also includes a monitoring unit, a processing unit, and a control unit. When the patient is lying on the bed, the monitoring unit monitors the medical staff and sends the monitoring results to the processing unit after recognizing the posture of the medical staff. When the posture of the medical staff changes, the control unit generates corresponding control commands based on the adjustment process of the medical staff's posture, controls at least one of the first adjustment component and the second adjustment component, and adjusts the position of the display screen so that the position of the display screen is adapted to the posture of the medical staff.

[0010] Furthermore, it also includes a voice recognition unit. After setting specific instructions, when the display screen is in motion, medical staff can issue specific instructions, which are then recognized by the voice recognition unit. After recognition, the control unit generates control commands to turn on or off at least one of the first and second adjustment components.

[0011] Furthermore, the first adjustment component includes a mounting bracket located on the surface of the adjustment plate, a first motor is provided on one side of the mounting bracket, the output end of the first motor extends into the interior of the mounting bracket, and a ball nut is provided on the exterior of the mounting bracket, and the display screen is detachably mounted on the top of the ball nut.

[0012] Furthermore, the linkage includes a threaded rod disposed on one side of the base. The threaded rod is connected to the output end of the second motor. After the second motor outputs power, it can drive the threaded rod to rotate. A threaded sleeve is disposed on the outside of the threaded rod. A support rod is disposed at the lower end of the threaded sleeve. The push rod is movably connected to the end of the support rod away from the threaded sleeve. A limiter is disposed between the push rod and the threaded sleeve to restrict the movement of the push rod.

[0013] Furthermore, the limiting component includes a limiting slide sleeve attached to the surface of the threaded sleeve, a limiting slide rod transversely passing through the inside of the limiting slide sleeve, a limiting ring being provided at the surface of the limiting slide rod extending to the pushing rod, and a limiting slider being fixedly provided on the surface of the pushing rod, the limiting slider sliding along the inside of the limiting ring.

[0014] Furthermore, the monitoring unit includes a monitoring module, a posture recognition module, and an identity recognition unit. After the patient is positioned on the bed, the identity recognition unit first verifies the identity of the medical staff who play a leading role. After the identity is verified, the monitoring module continuously monitors the medical staff and acquires their posture data based on their posture adjustment process. The posture recognition module then identifies the current posture of the medical staff and generates a recognition result.

[0015] Furthermore, the processing unit includes a modeling module, a prediction module, a judgment module, and an adjustment strategy library. The modeling module sends the posture data of medical personnel to the modeling module. After training and testing, a posture motion model of the medical personnel is established. When the medical personnel's posture is in an adjustment state, the prediction module simulates and predicts the posture adjustment process of the medical personnel, obtains the posture of the medical personnel after they are stationary, and generates a prediction result. The generated prediction result is sent to the control unit, which generates corresponding control commands to control the first or second adjustment component and adjust the position of the display screen.

[0016] Furthermore, the control method for at least one of the first adjustment component and the second adjustment component is as follows: the movement range and direction of the medical staff's head at the height of the base are obtained, and the judgment module determines whether the movement range is lower than the first threshold. When it is lower than the first threshold, the display screen is kept still. When the movement range of the medical staff's head is between the first threshold and the second threshold, the push rod pushes the adjustment plate to rotate along the top edge of the base. The rotation direction is consistent with the movement direction of the medical staff's head, and the rotation range is consistent with the movement range of the medical staff's head.

[0017] Furthermore, when the movement of the medical staff's head exceeds the second threshold, the ball nut drives the display screen to move along the height direction of the base when the push rod is rotated, and the direction of movement is consistent with the direction of movement of the medical staff's head; wherein, the first threshold is lower than the second threshold.

[0018] Furthermore, when the display screen moves with the head of the medical staff, the monitoring module acquires the movement process of the medical staff's head and the adjustment process of the display screen, and correlates the medical staff's posture adjustment process with the display screen adjustment process to form an adjustment strategy. After summarizing several adjustment strategies, an adjustment strategy library is constructed. When the posture recognition module recognizes the medical staff's posture adjustment again, it matches the corresponding adjustment strategy from the adjustment strategy library according to the medical staff's posture adjustment process, sends the adjustment strategy to the control unit, and the control unit generates corresponding control commands.

[0019] (III) Beneficial Effects

[0020] This invention provides an electronic display system for an angle-adjustable operating table. It has the following advantages:

[0021] 1. By setting the first adjustment component and the second adjustment component, the angle and position of the display screen can be adjusted so that the current position of the display screen is adapted to the head position of the medical staff. Under this condition, the medical staff can always observe the surface of the display screen and will not miss the information displayed on the display screen, thus making the display screen more convenient.

[0022] 2. By setting up monitoring and processing units, the posture of medical staff on the bed is monitored and identified. Based on the identification results, the first and second adjustment components are controlled to adjust the position of the display screen, so that the display screen is adapted to the position of the medical staff's head, reducing the frequency of the medical staff actively adjusting the position of the display screen; and the movement of medical staff can be predicted and dealt with in advance, improving the convenience of medical staff adjusting the display screen, thereby reducing unnecessary activities of medical staff.

[0023] 3. Different adjustment strategies are selected based on the range of movement of medical staff, so that the movement of the display screen can be more fully adapted to the movement of the medical staff's head. When the range of movement of the medical staff's head is large, different movement strategies can be selected, which is more targeted. Moreover, by recording the process of medical staff adjusting the display screen and forming corresponding adjustment strategies, when the same action is recognized again, the corresponding adjustment strategy is matched and the display screen is adjusted, improving the convenience for medical staff.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example

[0038] Please see Figures 1 to 5 This invention provides an electronic display system for an angle-adjustable operating table, comprising a display system body 10, a voice recognition unit 20, a first adjustment component 30, a second adjustment component 40, a monitoring unit 50, a processing unit 60, and a control unit 70, wherein...

[0039] The display system body 10 includes a vertically arranged and hollow base 11, a display screen 12 is arranged on one side of the base 11, and an adjustment plate 13 is hinged to the top edge of the base 11 near the display screen 12. The display screen 12 and the adjustment plate 13 are detachably fixed.

[0040] A second adjustment assembly 40 is provided inside the base 11. The second adjustment assembly 40 includes a second motor 43 located at the bottom of the base 11. A push rod 45 is provided above the second motor 43. The top end of the push rod 45 is hinged to the bottom of the adjustment plate 13. A linkage is provided between the second motor 43 and the push rod 45. After the second motor 43 outputs power, the linkage causes the push rod 45 to push the adjustment plate 13 to rotate along the edge of the base 11. A first adjustment assembly 30 is provided between the display screen 12 and the adjustment plate 13. The second adjustment assembly 40 causes the display screen 12 to slide up and down along the surface of the adjustment plate 13.

[0041] It also includes a monitoring unit 50, a processing unit 60, and a control unit 70, wherein,

[0042] When the patient is lying on the bed, the monitoring unit 50 monitors the medical staff. After recognizing the posture of the medical staff, the monitoring results are sent to the processing unit 60. When the posture of the medical staff changes, the control unit 70 generates corresponding control commands based on the adjustment process of the medical staff's posture, controls at least one of the first adjustment component 30 and the second adjustment component 40, and adjusts the position of the display screen 12 so that the position of the display screen 12 is adapted to the posture of the medical staff.

[0043] refer to Figure 5 It also includes a voice recognition unit 20. After setting specific instructions, when the display screen 12 is in motion, the medical staff will issue specific instructions and the voice recognition unit 20 will recognize them. After recognition, the control unit 70 will generate control commands to turn on or off at least one of the first adjustment component 30 and the second adjustment component 40.

[0044] When in use, as the display screen 12 moves with the head of the medical staff, the voice recognition unit 20 can control the display screen 12 after recognizing the specific instructions given by the medical staff, thus pausing further movement of the display screen 12.

[0045] refer to Figure 4The first adjustment component 30 includes a first motor 31, a mounting bracket 32, a ball screw 33, and a ball nut 34; wherein, the first adjustment component 30 includes a mounting bracket 32 ​​located on the surface of the adjustment plate 13, a first motor 31 is provided on one side of the mounting bracket 32 ​​for outputting power, the output end of the first motor 31 extends into the interior of the mounting bracket 32, and a ball nut 34 is provided on the exterior of the mounting bracket 32, and the display screen 12 is detachably mounted on the top of the ball nut 34.

[0046] In use, when the position of the display screen 12 needs to be adjusted, the first motor 31 is started to output power and drive the ball screw 33 to rotate. By utilizing the cooperation between the ball screw 33 and the ball nut 34, the ball nut 34 can be moved along the length of the ball screw 33 to adjust the position of the display screen 12.

[0047] refer to Figure 2 and Figure 3 The second adjustment component 40 includes a support rod 41, a limiting slider 42, a second motor 43, a threaded rod 44, a push rod 45, a threaded sleeve 46, a limiting slide sleeve 47, a limiting slide rod 48, and a limiting ring 49. The linkage component includes a threaded rod 44 disposed on one side of the base 11. The threaded rod 44 is connected to the output end of the second motor 43. After the second motor 43 outputs power, it can drive the threaded rod 44 to rotate. A threaded sleeve 46 is fitted externally to the threaded rod 44, and the threaded sleeve 46 can move along the height direction of the threaded rod 44. A support rod 41 is inclinedly disposed at the lower end of the threaded sleeve 46. The push rod 45 is movably connected to the end of the support rod 41 away from the threaded sleeve 46. A limiting component is disposed between the push rod 45 and the threaded sleeve 46 to restrict the movement of the push rod 45.

[0048] The limiting component includes a limiting slide sleeve 47 attached to the surface of the threaded sleeve 46. A limiting slide rod 48 is transversely inserted inside the limiting slide sleeve 47. A limiting ring 49 is provided at the surface of the pushing rod 45 where the limiting slide rod 48 extends. A limiting slider 42 is fixedly provided on the surface of the pushing rod 45. The limiting slider 42 slides along the inside of the limiting ring 49.

[0049] In use, when it is necessary to adjust the angle of the adjustment plate 13 and the display screen 12 located on the surface of the adjustment plate 13, the second motor 43 is started to output power to drive the threaded rod 44 to rotate. When the threaded sleeve 46 drives the limiting sleeve 47 to move along the length direction of the threaded rod 44, the limiting slide rod 48 slides along the inside of the limiting sleeve 47, driving the limiting slider 42 to move. Thus, with the cooperation of the limiting slide rod 48 and the limiting sleeve 47, and the limiting slider 42 and the limiting ring 49, the movement of the push rod 45 is limited. The push rod 45 adjusts the angle of the display screen 12, thereby adjusting the position of the display screen 12 so that the position of the display screen 12 is adapted to the posture of the medical staff.

[0050] refer to Figure 5 The monitoring unit 50 includes a monitoring module 51, a posture recognition module 52, and an identity recognition unit 53. After the patient is on the bed, the identity recognition unit 53 first verifies the identity of the medical staff who play a leading role. After the identity is verified, the monitoring module 51 continuously monitors the medical staff and obtains the posture data of the medical staff based on the process of the medical staff adjusting their posture. The posture recognition module 52 identifies the current posture of the medical staff and generates a recognition result.

[0051] When in use, the monitoring module 51 is set to monitor medical staff, which can understand the current status of medical staff in real time. After recognizing the posture of medical staff, the position of the display screen 12 can be adjusted according to the adjustment of the posture of medical staff.

[0052] refer to Figure 5 The processing unit 60 includes a modeling module 61, a prediction module 62, a judgment module 63, and an adjustment strategy library 64. The modeling module 61 sends the posture data of medical personnel to the medical personnel posture motion model after training and testing. When the medical personnel's posture is in an adjustment state, the prediction module 62 simulates and predicts the posture adjustment process of the medical personnel, obtains the posture of the medical personnel after they are stationary, and generates a prediction result. The generated prediction result is sent to the control unit 70, which generates corresponding control commands to control the first adjustment component 30 or the second adjustment component 40, and adjusts the position of the display screen 12.

[0053] The control method for at least one of the first adjustment component 30 and the second adjustment component 40 is as follows:

[0054] The movement range and direction of the medical staff’s head at the height of the base 11 are obtained. The judgment module 63 determines whether the movement range is lower than the first threshold. If it is lower than the first threshold, the display screen 12 remains stationary.

[0055] When the movement of the medical staff's head is between the first threshold and the second threshold, the push rod 45 pushes the adjustment plate 13 to rotate along the top edge of the base 11. The direction of rotation is the same as the direction of movement of the medical staff's head, and the range of rotation is the same as the range of movement of the medical staff's head. For example, when the medical staff's head moves downward, the adjustment plate 13 pushes the display screen 12 to rotate counterclockwise along the top edge of the base 11. When the medical staff's head moves downward by 20%, the range of rotation is also 20%.

[0056] When the movement of the medical staff's head exceeds the second threshold, the ball nut 34 drives the display screen 12 to move along the height direction of the base 11 when the push rod 45 is rotated, and the movement direction is consistent with the movement direction of the medical staff's head; for example, when the medical staff's head is raised significantly along the height direction of the base 11, the ball nut 34 drives the display screen 12 to move upward; wherein, the first threshold is lower than the second threshold.

[0057] In use, when the head of a medical staff member moves, the range and direction of the head movement are obtained. The control unit 70 generates a control command to adjust at least one of the first adjustment component 30 and the second adjustment component 40, thereby adjusting the height and angle of the display screen 12. This ensures that the adjustment process of the display screen 12 is consistent with the adjustment process of the medical staff member's head position, making the position of the display screen 12 adapt to the movement of the medical staff member's head. This reduces the need for medical staff to actively adjust and control the position of the display screen 12, increasing the convenience of the display screen 12.

[0058] Furthermore, different adjustment strategies are selected when adjusting the display screen 12 based on the range of head movement of medical staff, so that the movement of the display screen 12 fully corresponds to the movement of the medical staff's head, making it more targeted.

[0059] refer to Figures 1 to 5 When the display screen 12 moves with the head of the medical staff, the monitoring module 51 acquires the movement process of the medical staff's head and the adjustment process of the display screen 12 respectively, and matches the medical staff's posture adjustment process with the adjustment process of the display screen 12 to form an adjustment strategy.

[0060] After summarizing several adjustment strategies, an adjustment strategy library 64 is constructed. When the posture recognition module 52 recognizes the medical staff adjusting their posture again, it matches the corresponding adjustment strategy from the adjustment strategy library 64 based on the medical staff's posture adjustment process, sends the adjustment strategy to the control unit 70, and the control unit 70 generates corresponding control commands.

[0061] In use, the system records the changes in the posture of medical staff and the responses of the display screen 12, and forms an adjustment strategy. When the posture recognition module 52 recognizes that the medical staff has made the same posture adjustment again, the control unit 70 adjusts the display screen 12 according to the existing adjustment strategy, so that the display screen 12 can respond quickly and increase the efficiency of adjustment.

[0062] In summary:

[0063] By setting the first adjustment component 30 and the second adjustment component 40, the angle and position of the display screen 12 can be adjusted so that the current position of the display screen 12 is adapted to the head position of the medical staff. In this case, the medical staff can always observe the surface of the display screen 12 and will not miss the information displayed on the display screen 12, thus making the display screen 12 more convenient.

[0064] By setting up a monitoring unit 50 and a processing unit 60, the posture of medical staff is monitored and identified when they are on the bed. Based on the identification results, the first adjustment component 30 and the second adjustment component 40 are controlled, thereby adjusting the position of the display screen 12 to adapt to the position of the medical staff's head, reducing the frequency of the medical staff actively adjusting the position of the display screen 12. Furthermore, the movement of medical staff can be predicted and dealt with in advance, improving the convenience of medical staff adjusting the display screen 12 and reducing unnecessary activities of medical staff.

[0065] Different adjustment strategies are selected based on the range of movement of medical staff, so that the movement of the display screen 12 can be more fully adapted to the movement of the medical staff's head. When the range of movement of the medical staff's head is large, different movement strategies can be selected, which is more targeted. Moreover, by recording the process of medical staff adjusting the display screen 12 and forming corresponding adjustment strategies, when the same action is recognized again, the corresponding adjustment strategy is matched and the display screen 12 is adjusted, which improves the convenience for medical staff.

The electronic display system for an angle-adjustable operating table according to claim 3, characterized in that: The control method for at least one of the first adjustment component (30) and the second adjustment component (40) is as follows: The movement range and direction of the medical staff’s head at the height of the base (11) are obtained. The judgment module (63) determines whether the movement range is lower than the first threshold. If it is lower than the first threshold, the display screen (12) is kept still. When the movement of the medical staff’s head is between the first threshold and the second threshold, the push rod (45) pushes the adjustment plate (13) to rotate along the top edge of the base (11). The rotation direction is consistent with the movement direction of the medical staff’s head, and the rotation amplitude is consistent with the movement amplitude of the medical staff’s head.

5. The electronic display system for an angle-adjustable operating table according to claim 4, characterized in that: When the movement of the medical staff’s head is greater than the second threshold, when the push rod (45) is rotated, the ball nut (34) drives the display screen (12) to move along the height direction of the base (11), and the movement direction is consistent with the movement direction of the medical staff’s head; wherein, the first threshold is lower than the second threshold.

6. The electronic display system for an angle-adjustable operating table according to claim 5, characterized in that: When the display screen (12) moves with the head of the medical staff, the monitoring module (51) acquires the movement process of the head of the medical staff and the adjustment process of the display screen (12) respectively, and the adjustment process of the medical staff's posture is matched with the adjustment process of the display screen (12) to form an adjustment strategy; after summarizing several adjustment strategies, an adjustment strategy library (64) is constructed. When the posture recognition module (52) recognizes the adjustment posture of the medical staff again, it matches the corresponding adjustment strategy from the adjustment strategy library (64) according to the posture adjustment process of the medical staff, sends the adjustment strategy to the control unit (70), and the control unit (70) forms the corresponding control command.
