DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0016] like Figure 1 - Figure 5 As shown, a multifunctional positioning device for fracture CT diagnosis includes a support frame 1, a bottom plate 2 is provided at the lower end of the support frame 1, a weight bag 3 is connected between the two bottom plates 2, an angle adjustment structure 4 is provided at the upper end of the support frame 1, and a fixing structure 5 is connected to the angle adjustment structure 4. A carrying handle 6 is fixedly installed on the bottom plate 2, and the bottom plate 2 is fixedly connected to the support frame 1, and the weight bag 3 is filled with sand.

[0017] When diagnosing a fracture patient, the multifunctional fracture CT diagnostic device is used for diagnosis. The entire positioning device is carried by the handle 6 on the bottom plate 2, and the positioning device is carried to the diagnostic table for placement. At this time, under the action of the sand in the counterweight bag 3, the entire device has good stability, and due to the deformable characteristics of the counterweight bag 3, the entire counterweight bag 3 can be adapted to the curved surface of the diagnostic table for placement, thereby ensuring the stability of the device. After the device is placed on the diagnostic table, the device is connected to a power supply, and the angle adjustment structure 4 is used to adjust the angle of the fixed structure 5 so that the fixed structure 5 is better aligned with the patient's limb that needs to be positioned and fixed, and then the fixed structure 5 is used to position and fix the patient's limb. After the positioning is completed, the multifunctional fracture CT diagnostic device is started for diagnosis. During this process, under the action of the positioning device, the patient's limb has good stability and will not be displaced, thereby ensuring the accuracy of the diagnostic scan and the accuracy of the diagnosis. When the diagnostic work is completed, the fixed structure 5 is raised to give way, and then the device is carried by the handle 6 for storage.

[0018] It should be noted that a weight bag 3 is provided between the base plates 2, and the weight bag 3 is filled with sand, so that the entire device can be directly placed on the diagnostic table for use, which is convenient for subsequent position adjustment without affecting the stability of use.

[0019] According to the above embodiment, the angle adjustment structure 4 includes a connecting plate 401, a rotating plate 402, a worm gear 403, a driving rod 404, a worm 405 and an adjusting wheel 406. The connecting plate 401 is fixedly connected to the rotating plate 402 through a connecting shaft, and the connecting shaft passes through the top of the support frame 1, and the worm gear 403 is fixed to the lower end of the rotating plate 402. The driving rod 404 is fixedly connected to the worm 405, and the driving rod 404 is rotatably mounted on the support frame 1, the worm 405 is meshedly connected to the worm gear 403, one end of the driving rod 404 passes through the support frame 1, and the end of the driving rod 404 is fixedly connected to the adjusting wheel 406.

[0020] When the positioning device is used to position and fix the patient's limbs, the fixed structure 5 is installed on the connecting plate 401 in the angle adjustment structure 4, and the connecting plate 401 is connected to the rotating plate 402 through the connecting shaft that penetrates the support frame 1. Under the action of the rotating plate 402 and the connecting plate 401, the fixed structure 5 can be used stably. When it is necessary to change the angle of the fixed structure 5 relative to the support frame 1, the medical staff rotates the driving rod 404 through the adjusting wheel 406 on one side of the support frame 1, and the driving rod 404 rotates on the support frame 1, thereby driving the worm 405 to rotate, and the worm 405 drives the worm wheel 403 to rotate slowly, and then drives the rotating plate 402 and the connecting plate 401 to rotate. The fixed structure 5 is adjusted in angle as it rotates, and is used after the angle is adjusted. At this time, under the self-locking effect of the worm wheel 403 and the worm 405, the fixed structure 5 is fixed relative to the support frame 1, which can ensure stability during use.

[0021] The angle adjustment structure 4 is used to install the fixed structure 5, and the angle of the fixed structure 5 can be adjusted according to actual conditions, which improves the flexibility of use, can better position and fix the patient's limbs, and ensures the accuracy of subsequent diagnosis. The worm gear 403 and the worm 405 are arranged in the angle adjustment structure 4, which have a self-locking effect after adjustment, thereby ensuring the stability after adjustment.

[0022] According to the above implementation scheme, the fixed structure 5 includes a fixed plate 501, a first electric push rod 502, a position adjustment component 503, a second electric push rod 504, a first lifting plate 505, a second lifting plate 506 and a positioning cloth belt 507. The fixed plate 501 is fixedly mounted on the angle adjustment structure 4, and a first mounting groove is provided on the fixed plate 501. The first electric push rod 502 is arranged in the first mounting groove on the fixed plate 501, and the first lifting plate 505 is fixed to the lower end of the first electric push rod 502. The position adjustment component 503 is connected to the fixed plate 501, the second electric push rod 504 is installed on the position adjustment component 503, and the lower end of the second electric push rod 504 is fixedly connected to the second lifting plate 506. One end of the positioning cloth belt 507 is connected to the first lifting plate 505, and the other end is connected to the second lifting plate 506.

[0023] When the fixing structure 5 is used to position and fix the patient's limbs, after adjusting the angle of the fixing structure 5, the position of the second electric push rod 504 is adjusted according to the patient's condition. During the adjustment, the position adjustment component 503 is used to move the second electric push rod 504, thereby changing the relative position of the second electric push rod 504 and the first electric push rod 502. After the adjustment is completed, the first electric push rod 502 and the second electric push rod 504 are started by the remote control, and the first electric push rod 502 and the second electric push rod 504 respectively bring the first lifting plate 505 and the second lifting plate 506 down, and the positioning cloth belt 507 is lowered together until the positioning cloth belt 507 is pressed on the patient's limb for positioning and fixing. In this process, the first electric push rod 502 and the second electric push rod 504 can be controlled separately, so that the first lifting plate 505 and the second lifting plate 506 can be lowered to different heights, thereby improving the flexibility and adaptability of use. In the process of fixing the patient's limbs, due to the flexible characteristics of the positioning cloth belt 507, while ensuring positioning and fixing, it can also protect the patient's limbs and avoid secondary damage to the patient's limbs. After the patient's limbs are positioned and fixed, the multifunctional fracture CT diagnostic device can be started for diagnosis. After the diagnosis is completed, the first electric push rod 502 and the second electric push rod 504 are started, and the two lifting plates with the positioning cloth belt 507 rise to make way, and then the patient can get off the diagnostic table.

[0024] It should be noted that, through the setting of the fixed structure 5, the first lifting plate 505 and the second lifting plate 506 are respectively set at the lower ends of the two electric push rods, and a positioning cloth belt 507 is set between the two lifting plates to flexibly position and fix the patient's limbs, thereby ensuring the positioning and protecting the patient's limbs. The two lifting plates are driven by two electric push rods respectively, and the corresponding lifting plates can be independently driven to move, which can better adapt to the positioning and fixation of the patient's limbs and has high adaptability.

[0025] The position adjustment assembly 503 includes a movable seat 5031, a guide rod 5032, a groove 5033, a rotating shaft 5034, a baffle 5035, an adjusting screw 5036, a control plate 5037 and a limiting pressure plate 5038. The movable seat 5031 is fixedly connected to the guide rod 5032, and the guide rod 5032 is connected to the fixed plate 501. The groove 5033 is opened on the movable seat 5031, and the rotating shaft 5034 is fixed to the baffle 5035. The rotating shaft 5034 is connected, and the rotating shaft 5034 is located in the groove 5033, the baffle 5035 is located at both ends of the movable seat 5031, the adjusting screw 5036 is fixedly connected to the rotating shaft 5034, and the adjusting screw 5036 is threadedly connected to the fixed plate 501, the control board 5037 is installed at the end of the rotating shaft 5034, the limiting pressure plate 5038 is fixed to the movable seat 5031 by screws, and the limiting pressure plate 5038 limits the rotating shaft 5034.

[0026] When the position adjustment component 503 is used to adjust the position of the second electric push rod 504, the control plate 5037 rotates the rotating shaft 5034. Under the action of the limiting pressure plate 5038, the rotating shaft 5034 rotates in the groove 5033, and under the action of the baffle 5035, the rotating shaft 5034 will not have a horizontal displacement. During the rotation of the rotating shaft 5034, the adjusting screw 5036 rotates together, thereby applying a force to the fixed plate 501. Since the fixed plate 501 is fixed on the angle adjustment structure 4, a reverse force is applied to the adjusting screw 5036, so that the adjusting screw 5036 moves on the fixed plate 501, and then the movable seat 5031 moves relative to the fixed plate 501 through the guide rod 5032, thereby achieving the purpose of adjusting the position of the second electric push rod 504. After the position is adjusted, it is used. At this time, the threaded connection between the adjusting screw 5036 and the fixed plate 501 has a self-locking effect, so that the position of the movable seat 5031 can be relatively fixed, thereby ensuring stability during use.

[0027] It should be noted that, by adopting the position adjustment component 503, the position of the second electric push rod 504 can be adjusted, thereby improving the flexibility and adaptability of use. The rotating shaft 5034 is located in the groove 5033, and is used in conjunction with the limiting pressure plate 5038 and the baffle 5035. While ensuring normal adjustment, it can be quickly disassembled to facilitate replacement work. Since the baffle 5035 fits the two ends of the movable seat 5031, it can not only ensure the stability of the movable seat 5031 after adjustment, but also will not affect the normal rotation of the rotating shaft 5034, and the use effect is excellent.
