[0043] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] For ease of understanding, the system to which the present application is applicable is first described. The traction bed adjustment method provided in the present application can be applied to a tension spinal traction bed, which includes an X-ray fluoroscopy machine, a traction bed, an image display system and a control console. Among them, the X-ray fluoroscopy machine and the traction bed are arranged into an integrated structure, and the X-ray fluoroscopy machine includes an X-ray tube, a high-voltage generator and a flat-panel detector. The X-ray tube, as the core component of the X-ray fluoroscopy machine, is used to generate X-rays and is located on the opposite side above the traction bed. It can be moved forward and backward to the position ranging from the cervical vertebra to the lumbar vertebra according to demand. The high-voltage generator provides the required high voltage for the X-ray tube to ensure the generation and intensity of the X-rays, and can be arranged behind the X-ray tube or at the overall power supply of the traction bed. The flat-panel detector is used to receive X-rays that pass through the human body and convert them into image signals for display and analysis, and can share an integrated structure with the traction bed board.

[0045] The image display system is used to display X-ray fluoroscopy images on the screen for doctors to observe in real time. It usually includes a monitor and image processing software, which can enhance image quality and provide clearer diagnostic information. The image display, traction bed parameter adjustment interface and AI processor interface all share the same display.

[0046] The console and the image display system share the same AI processor and display, which are used to control the working parameters of the X-ray machine, such as adjusting the X-ray intensity, exposure time, image magnification, etc. The operator sets and adjusts various parameters of the machine through the console. The AI ​​processor is used to calculate the change in the height of the intervertebral disc before and after the force is applied to the part to be pulled, and then determine the linear relationship between the traction force and the degree of retraction of the intervertebral disc at the part to be pulled, and calculate the optimal traction force based on the linear relationship.

[0047] The X-ray fluoroscopy machine may also include other structures, such as mechanical supports, hospital beds or examination tables, filters, and electric or manual adjustment devices, which can be added to the traction bed or the shared traction bed structure. The mechanical support is used to support the X-ray tube, detector and other components, and provide flexible mechanical movement and positioning functions so that the patient can be examined at different angles and positions. The hospital bed or examination table is used for the patient to lie down or maintain a fixed posture to facilitate X-ray fluoroscopy operations. The hospital bed can usually be moved or tilted to meet different examination requirements. The filter is used to filter the soft X-ray components in the X-ray beam to reduce unnecessary radiation and improve image quality. The electric or manual adjustment device is used to accurately adjust the position and angle of the X-ray tube and detector to ensure accurate fluoroscopy of the target area.

[0048] The traction bed includes a traction bed power module, a traction force sensor, a traction bed body, a neck / waist / lower limb fixation belt, and a traction suit. The traction bed power module is used to accurately transmit the optimal traction force issued by the AI ​​processor to the bed board and the fixation belt. The traction force sensor is used to monitor the traction force provided by the traction bed power module in real time and output a set of differential signals for feedback to the AI ​​processor. The traction bed body, the neck / waist / lower limb fixation belt, and the traction suit are used to fix the front and rear ends of the part to be tractioned and provide traction points.

[0049] Figure 1 A flow chart of a traction bed adjustment method provided in an embodiment of the present application, such as Figure 1 As shown, the method may include the following steps:

[0050] S110, obtaining X-ray fluoroscopic images of the part to be pulled before and after the initial pulling force is applied.

[0051] The part to be pulled can be the neck, waist or lower limbs. When the patient is in place on the traction bed, the part to be pulled is scanned by the X-ray tube of the X-ray fluoroscopy machine, and the flat panel detector receives the X-rays that pass through the part to be pulled and converts them into X-ray fluoroscopy images. The initial traction force is the traction force that is initially set based on the linear relationship between the traction force and the degree of retraction of the intervertebral disc at the part to be pulled, which will not produce too much tension on the part to be pulled.

[0052] When no traction force is applied to the part to be pulled, an X-ray fluoroscopy image of the part to be pulled is obtained once by the X-ray fluoroscopy machine, and when an initial traction force is applied to the part to be pulled, an X-ray fluoroscopy image of the part to be pulled is obtained again by the X-ray fluoroscopy machine.

[0053] S120, determining a linear relationship between the traction force and the degree of retraction of the intervertebral disc at the site to be traction based on the initial traction force and X-ray fluoroscopic images of the site to be traction before and after the initial traction force is applied.

[0054] The degree of disc retraction can be determined by the intervertebral space width, that is, the distance between two vertebrae. The increase in intervertebral space width indirectly reflects disc retraction. When traction is applied to the part to be tractioned, the degree of disc retraction will change, and the effect of the applied traction on the part to be tractioned can be known.

[0055] The retraction of the protruding disc can be directly observed from the X-ray fluoroscopic image, and the vertical distance from the outermost edge of the protruding disc to the posterior edge of the vertebral body, i.e., the disc height, is measured. The linear relationship between the traction force and the degree of retraction of the disc at the site to be traction is calculated by the initial traction force and the vertical distance from the outermost edge of the disc to the posterior edge of the vertebral body.

[0056] S130, determining an optimal traction force corresponding to the preset intervertebral disc retraction degree data according to a linear relationship between the traction force and the retraction degree of the intervertebral disc at the position to be tractioned.

[0057] The preset disc retraction degree data is the disc retraction ratio that the doctor wants to achieve at the site to be pulled based on the X-ray fluoroscopic image and his / her own experience. The parameters can be set according to the actual situation of the patient. For example, patients with obvious disc herniation can set the disc retraction degree to require a retraction of more than 50%; if the herniation is not obvious, the disc length can be set to increase by 15% according to the intervertebral space.

[0058] The intervertebral disc height from the outermost edge of the protruding intervertebral disc to the posterior edge of the vertebral body at the traction site is calculated based on the preset intervertebral disc retraction degree data, and the intervertebral disc height is substituted into the linear relationship between the traction force and the intervertebral disc retraction degree at the traction site to obtain the optimal traction force.

[0059] S140, adjusting the traction bed according to the optimal traction force corresponding to the preset intervertebral disc retraction degree data.

[0060] The traction bed power module of the traction bed accurately applies the best traction force to the traction bed body and the fixing belt to adjust the traction bed so that the traction bed applies force to the traction part according to the best traction force. During the force application process, the traction force applied by the traction bed power module and the pain signal value of the traction part are also obtained in real time to avoid causing harm to the patient.

[0061] It can be seen that the embodiment of the present application obtains X-ray fluoroscopy images of the part to be traction before and after the initial traction force is applied, determines the linear relationship between the traction force and the degree of retraction of the intervertebral disc at the part to be traction according to the initial traction force and the X-ray fluoroscopy images of the part to be traction before and after the initial traction force is applied, determines the optimal traction force corresponding to the preset intervertebral disc retraction degree data according to the linear relationship between the traction force and the degree of retraction of the intervertebral disc at the part to be traction, adjusts the traction bed according to the optimal traction force corresponding to the preset intervertebral disc retraction degree data, so that the traction bed applies force to the part to be traction according to the optimal traction force, and the traction degree of the part to be traction can be more accurately and objectively known through the X-ray fluoroscopy images, thereby avoiding insufficient force due to individual subjective differences in patients, and calculating the optimal traction force based on the linear relationship between the traction force and the degree of retraction of the intervertebral disc at the part to be traction can maximize the effect of traction therapy.

[0062] As a feasible method, according to the initial traction force and the X-ray fluoroscopic images of the part to be traction before and after the initial traction force is applied, the linear relationship between the traction force and the degree of retraction of the intervertebral disc at the part to be traction is determined, including:

[0063] According to the X-ray fluoroscopic images of the part to be pulled before and after the initial traction force is applied, the intervertebral disc height of the part to be pulled before and after the initial traction force is applied is obtained;

[0064] According to the initial traction force and the height of the intervertebral disc at the site to be traction before and after the initial traction force is applied, the linear relationship between the traction force and the retraction degree of the intervertebral disc at the site to be traction is determined.

[0065] The intervertebral disc height is the vertical distance from the outermost edge of the intervertebral disc to the posterior edge of the vertebral body, which can be measured in the X-ray fluoroscopic image. For example, when traction of the lumbar spine is required, an X-ray fluoroscopic image is taken before the initial traction force is applied, and the L1-S1 distance A1 is measured in the X-ray fluoroscopic image, that is, the distance from the upper edge of the first lumbar vertebra to the upper edge of the first sacral vertebra. After the initial traction force is applied and fixed, another X-ray fluoroscopic image is taken, and the L1-S1 distance A2 is measured in the X-ray fluoroscopic image. The difference between the two values ​​D(A1-A2) is the height difference of the 5 intervertebral discs between L1-S1.

[0066] First, take an X-ray fluoroscopic image before applying the initial traction force to obtain the baseline data, expressed as B1 cm; when the initial traction force is applied, it changes to B2 cm, where B2 = B1 + D. B1 is the intervertebral disc height of the part to be tractioned before the initial traction force is applied, and B2 is the intervertebral disc height of the part to be tractioned after the initial traction force is applied.

[0067] According to the initial traction force and the height of the intervertebral disc at the site to be traction before and after the initial traction force is applied, the linear relationship between the traction force and the retraction degree of the intervertebral disc at the site to be traction is determined.

[0068] Specifically, the traction force at the to-be-tractioned part before the initial traction force is applied is 0, and 0 and the intervertebral disc height at the to-be-tractioned part before the initial traction force is applied are matched as the first data set;

[0069] matching the initial traction force and the intervertebral disc height of the part to be tractioned after the initial traction force is applied to form a second data set;

[0070] The linear relationship between the traction force and the retraction degree of the intervertebral disc at the site to be distracted is determined based on the first data set and the second data set.

[0071] The traction force at the part to be tractioned before the initial traction force is applied is 0, and the baseline data obtained is B1cm, that is, the intervertebral disc height at the part to be tractioned before the initial traction force is applied is B1cm, and the first data group can be represented by (0, B1). The initial traction force is represented by Q, and the intervertebral disc height at the part to be tractioned after the initial traction force is applied is B2, and the first data group can be represented by (Q, B2). From these two data groups, a linear relationship between the traction force and the degree of retraction of the intervertebral disc at the part to be tractioned can be obtained.

[0072] As a feasible method, according to the linear relationship between the traction force and the retraction degree of the intervertebral disc at the part to be tractioned, the optimal traction force corresponding to the preset intervertebral disc retraction degree data is determined, including:

[0073] Determine the retraction height of the intervertebral disc at the site to be pulled according to the preset intervertebral disc retraction degree data and the X-ray fluoroscopic image of the site to be pulled after the initial traction force is applied;

[0074] Based on the linear relationship between the intervertebral disc retraction height and the traction force and the intervertebral disc retraction degree of the traction site, the optimal traction force corresponding to the preset intervertebral disc retraction degree data is determined.

[0075] The X-ray fluoroscopic image of the part to be pulled after the initial traction force is applied is the latest state before the optimal traction force is applied. Applying force again on this basis can ensure that the traction force applied again can match the current traction state of the part to be pulled.

[0076] The intervertebral disc height of the part to be pulled after the initial traction force is applied is obtained through the X-ray fluoroscopic image of the part to be pulled after the initial traction force is applied, and the intervertebral disc retraction degree data is preset as the intervertebral disc retraction ratio. According to the ratio and the intervertebral disc height of the part to be pulled after the initial traction force is applied, the intervertebral disc retraction height that the part to be pulled needs to be pulled can be calculated, and the intervertebral disc height of the part to be pulled after the initial traction force is applied and the intervertebral disc retraction height are added to obtain the intervertebral disc height that the part to be pulled needs to be pulled. The intervertebral disc height that the part to be pulled needs to be pulled is substituted into the linear relationship between the traction force and the intervertebral disc retraction degree of the part to be pulled to obtain the optimal traction force.

[0077] As a feasible method, the traction bed is adjusted according to the optimal traction force corresponding to the preset intervertebral disc retraction degree data, including:

[0078] According to the optimal traction force corresponding to the preset intervertebral disc retraction degree data, the module for fixing the part to be traction in the traction bed is adjusted;

[0079] Obtain the pain signal value of the part to be tractioned, and determine whether to continue adjusting the traction bed based on the pain signal value and the pain signal threshold.

[0080] The module for fixing the part to be traction mainly includes a traction bed, a neck / waist / lower limb fixing belt and a traction suit. The traction bed power module of the traction bed accurately applies the best traction force to the traction bed and the fixing belt to adjust the traction bed so that the traction bed applies force to the part to be traction according to the best traction force.

[0081] In order to avoid patient injury due to excessive traction force, the pain signal value of the part to be tractioned is obtained in real time, and based on the pain signal value and the pain signal threshold, it is determined whether to continue adjusting the traction bed. Specifically, when the pain signal value does not exceed the pain signal threshold, the traction bed continues to be adjusted. When the pain signal value exceeds the pain signal threshold, an alarm is sounded to suspend the adjustment of the traction bed.

[0082] As an achievable manner, the method further includes: obtaining an X-ray fluoroscopic image of the part to be pulled after applying the optimal pulling force;

[0083] Through the X-ray fluoroscopic image of the part to be tractioned after the optimal traction force is applied, it is judged whether the intervertebral disc height of the part to be tractioned with the optimal traction force meets the preset intervertebral disc retraction degree data.

[0084] In order to avoid errors in the calculated linear relationship due to errors in the previous measurement of the intervertebral disc height, it is necessary to take an X-ray fluoroscopic image of the part to be tractioned again after applying the optimal traction force to check whether the doctor's traction requirements are met. If the intervertebral disc height measured in the X-ray fluoroscopic image is close to the intervertebral disc height to be pulled to the part to be tractioned, then the intervertebral disc height of the part to be tractioned with the optimal traction force meets the preset intervertebral disc retraction degree data. If the intervertebral disc height measured in the X-ray fluoroscopic image is significantly different from the intervertebral disc height to be pulled to the part to be tractioned, then the intervertebral disc height of the part to be tractioned with the optimal traction force does not meet the preset intervertebral disc retraction degree data. At this time, the applied traction force can be adjusted according to the actual situation after applying the optimal traction force, so that the traction force of the part to be traction reaches the best.

[0085] It should be understood that although Figure 1 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in the application, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.
