The middle part of the bottom plate is provided with a sliding groove suitable for the extension plate to slide. The bottom plate is fixed with the connecting band. The bone fixation splint device can fix both sides of the knee and adjust the length of the front and rear splints of the knee, thereby achieving the purpose of not affecting the patient's activity of the knee joint. However, the bone fixation splint device only has a fixing function and cannot monitor the pressure of the fixed part of the limb in real time, which makes it difficult to find the deviation of the fixed part in time and affects the treatment effect of the patient, and even causes complications.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] An auxiliary fixation device for bone tumor patients capable of monitoring and correction, such as Figures 1-10As shown, it includes a first clamping ring 1, a second clamping ring 2, a splicing component, a fixing component, and a monitoring component. The second clamping ring 2 is rotatably connected to the lower side of the first clamping ring 1. Both the first clamping ring 1 and the second clamping ring 2 are provided with splicing components. A fixing component is provided between the first clamping ring 1 and the second clamping ring 2. Both the first clamping ring 1 and the second clamping ring 2 are provided with monitoring components.

[0030] like Figures 1-10 As shown, the splicing assembly includes a splicing boss 3 and a splicing recess 4. The first clamping ring 1 and the second clamping ring 2 are both connected to the left side of the splicing boss 3, and the first clamping ring 1 and the second clamping ring 2 are both connected to the right side of the splicing recess 4.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 10 As shown, the fixing assembly includes a grooved plate 5, a connecting block 6, a telescopic plate 7, and a bidirectional lead screw 8. The grooved plate 5 is connected to the front side of both the first clamping ring 1 and the second clamping ring 2. The connecting blocks 6 are snapped into the left and right sides of the grooved plate 5. The telescopic plates 7 are slidably connected between two adjacent connecting blocks 6. The bidirectional lead screw 8 is rotatably connected to the telescopic plate 7. The surface of the bidirectional lead screw 8 is machined with bidirectional helical raceways. The connecting blocks 6 are equipped with ball nuts. The ball nuts on the connecting blocks 6 are adapted to the raceways of the adjacent bidirectional lead screw 8. The upper side of the bidirectional lead screw 8 is provided with a limiting block to facilitate limiting the connecting blocks 6.

[0032] like Figure 3 , Figure 5 and Figure 10 As shown, it also includes a knob 9. The lower side of the bidirectional lead screw 8 is connected to a knob 9. The knob 9 is provided with anti-slip texture for easy gripping and rotation.

[0033] like Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the monitoring component includes a padding layer 10, a pressure sensor 11, a small electric actuator 12, and a corrective push plate 13. The padding layer 10 is connected to the side of the first clamping ring 1 and the second clamping ring 2 that are close to each other. The pressure sensor 11 is connected to the middle of the padding layer 10. The small electric actuator 12 is connected to the left and right sides of the first clamping ring 1 and the second clamping ring 2. The pressure sensor 11, the small electric actuator 12, and the processor are electrically connected through a control module. The corrective push plate 13 is connected to the telescopic end of the small electric actuator 12. The corrective push plate 13 is an arc-shaped structure to facilitate the correction of the limb. The inner side of the corrective push plate 13 is provided with a silicone buffer pad to avoid damage to the limb. The corrective push plate 13 penetrates the adjacent padding layer 10.

[0034] When using this invention, firstly, according to the length of the patient's limb, select several sets of first clamping rings 1 and second clamping rings 2, and complete the series splicing by the snap-fit ​​cooperation of splicing bosses 3 and splicing concave platforms 4 to form a fixing device of suitable length.

[0035] Then, the fixation device is placed on the outside of the patient's affected limb. Then, the connecting block 6 is clamped on the groove plate 5. Then, the bidirectional screw 8 is rotated by the knob 9 to move the connecting block 6 along the telescopic plate 7. The distance between the groove plates 5 is adjusted until the first clamping ring 1 and the second clamping ring 2 are in contact with the limb surface. The pressure is buffered by the soft pad layer 10 to avoid pressure injury.

[0036] The pressure sensor 11 collects limb pressure data in real time. When the limb is displaced, the pressure sensor 11 detects the pressure change. The processor starts the small electric push rod 12 through the control module, drives the correction pusher 13 to extend and fit the limb, and dynamically corrects the displaced part to maintain the limb alignment accuracy. This enables real-time monitoring of the fixed part and precise correction based on the monitoring status, thereby improving the treatment effect.

[0037] When it is necessary to disassemble this device, turn the knob 9 in the opposite direction to remove the connecting block 6 from the groove plate 5, and then turn to open the first clamping ring 1 and the second clamping ring 2 to remove the device.

[0038] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
