[0022] During operation, when the tibia and fibula are fractured, it is necessary to fix them first, and then to perform traction and stretching, so that the two ends of the fractured bones are combined to complete the reduction, so as to promote the recovery of the fractured position of the patient. When the patient needs to be treated for rapid recovery, the embodiment of the present invention is used. First, the device is applied to the scenario of tibia and fibula fracture reduction. First, the upper hoop frame 5 is flipped to one side, and the upper hoop frame 5 drives the buckle 7 to separate from the lock core inside the lower hoop body 1. The medical staff places the patient's leg between the lower hoop body 1 and the upper hoop frame 5. The fibula is aligned with the bottom of the cushion layer 6, and then the upper hoop frame 5 is closed; with continued use, when the leg circumference needs to be adjusted due to the different thickness of the patient's leg circumference, the buckle 7 is gradually pressed downward again using the embodiment of the present invention, and the buckle 7 is clamped in one of the three lock holes on the outer periphery of the lower hoop body 1 according to the appropriate size of the leg circumference. The buckle 7 drives the arc bar 8 to move downward, and the arc bar 8 pulls the elastic clamping block 9 downward to move. After the adjustment is completed, the elastic clamping block 9 is engaged with one of the multiple clamping grooves on the inner wall of the upper hoop frame 5, so that it is suitable for patients with different leg circumferences.

[0023] like Figure 3 to Figure 4 As shown, a massage component is installed on the lower surface of the cushion layer 6, and the massage component is connected to the side frame; the multiple upper panels 4 include a fixed part and two movable parts slidably arranged at the end of the main shaft 3, and the two ends of the fixed part are provided with an electric telescopic rod 41 for driving the two movable parts to move; a straight frame is installed between the two ends of the two side frames, and the straight frame includes a fixed block and two movable blocks slidably arranged at the two ends of the fixed block, and the two ends of the fixed block are provided with a guide rod 40, and the two movable blocks are slidably connected to the guide rod 40; the main shaft 3 is composed of an outer shell and a shaft body, and a torsion spring is arranged between the shaft body and the outer shell; it should be noted that the fixed part is connected to the main shaft 3, and the fixed part of the upper panel 4, the two movable parts are correspondingly connected to the fixed block and the two movable blocks of the straight frame close to the upper panel 4.

[0024] During operation, after the fracture is reduced and fixed, massage can be used to promote the recovery of the fracture during the recovery period. The electric telescopic rod 41 drives the two moving parts to move back and forth, thereby driving the two moving blocks of the straight frame to move back and forth, and further driving the two side frames to move back and forth, thereby driving the massage component to work and realizing massage action on the patient's fracture site; it should be noted that the upper closing plate 4 is slidably connected to the outer shell of the main shaft 3.

[0025] like Figures 3 to 5 As shown, the cushion layer 6 is slidably connected with the straight frame, the cushion layer 6 is made of elastic material, the massage component is used to press down and gently knead the parts around the fracture of the patient, the massage component includes a main support bar 61 installed under the cushion layer 6, the main support bar 61 is penetrated by a plurality of support columns 62, the support columns 62 are penetrated by an oblique support rod 63, both ends of the oblique support rod 63 are fixedly connected with a rotating wheel 1 64, the two ends of the plurality of support columns 62 are respectively fixedly connected with a rotating wheel 2 65 and a toothed disc 66, a push plate 60 is fixedly connected to the side of the side frame close to the cushion layer 6, and a rack 67 is fixedly connected to the side of the push plate 60; the rack 67 is meshed with the toothed disc 66; a plurality of soft rubber heads are installed on the top of the rotating wheel 2 65; During operation, since the psychological burden of the patient is heavy when the fracture is reduced, it is necessary to massage and relax the patient after the operation. The embodiment of the present invention is used to squeeze the side frames from both sides to move the push plate 60, and the push plate 60 pushes the rack 67 to work. The rack 67 moves and engages with the toothed disk 66 on the lower surface of the cushion layer 6. When the toothed disk 66 rotates, it drives the support column 62 to move. When the toothed disk 66 rotates, it drives the second rotating wheel 65 to move synchronously. The second rotating wheel 65 gradually massages the position of the leg between the lower hoop body 1 and the upper hoop frame 5. The movement of the support column 62 is linked to the synchronous movement of the diagonal support rod 63. The diagonal support rod 63 and the second rotating wheel 65 press on the human leg and rub the muscles, which reduces the tension of the human body, promotes the psychological comfort of the patient, and at the same time promotes blood circulation and improves the comfort of the patient's legs.

[0026] like Figures 7 to 9 As shown, a stabilizing component is also installed on one side of the two moving parts close to the fixed part, and the stabilizing component includes a push block 44, and a clamping head 45 is fixedly connected to the end of the push block 44. A groove is provided on the side of the clamping head 45, and a clamping socket is provided at both ends of the fixed part. A mounting hole is provided on the inner wall of the clamping socket, and a clamping column 46 is provided in the mounting hole. A reset spring 47 is provided between the clamping column 46 and the inner wall of the mounting hole.

[0027] During operation, although different parts can be massaged, in order to improve the comfort level, when no massage is performed, the position of the side frame needs to be fixed to improve the squeezing and fixing effect on the fractured part. To this end, the electric telescopic rod 41 drives the moving parts on both sides to move, which drives the push block 44 to move, and the push block 44 drives the clamping head 45 to move. The clamping head 45 gradually moves toward the direction of the fixing part. During the insertion of the clamping head 45 into the bayonet, the clamping column 46 is squeezed into the mounting hole. At this time, the reset spring 47 is in a compressed state; when the groove is aligned with the clamping column 46, the reset spring 47 releases the elastic force to push the clamping column 46 out of the mounting hole and clamp it into the groove to form a lock, so that the positions of the two moving parts remain stable, thereby fixing the position of the side frame and improving the fixing effect on the fractured part; When the lock needs to be canceled, the electric telescopic rod 41 drives the push block 44 to slide outward, so that the clamping column 46 is pulled out of the groove, so that the two moving parts can move back and forth.

[0028] Working principle: When performing fracture reduction treatment on the tibia and fibula, it is necessary to fix the fracture first, and then perform traction and stretching to merge the two ends of the fractured bones to complete the reduction, so as to promote the recovery of the fractured position of the patient. When the patient needs to be quickly recovered, the embodiment of the present invention is used. First, the device is applied to the scene of fracture reduction of the tibia and fibula. First, the upper hoop frame 5 is flipped to one side, and the upper hoop frame 5 drives the buckle 7 to separate from the lock core inside the lower hoop body 1. The medical staff places the patient's leg between the lower hoop body 1 and the upper hoop frame 5. The tibia and fibula are aligned with the lower side of the cushion layer 6, and then the upper hoop frame 5 is closed; with continued use, when the leg circumference needs to be adjusted due to the different thickness of the patient's leg circumference, the buckle 7 is gradually pressed downward again using the embodiment of the present invention, and the buckle 7 is clamped in one of the three lock holes on the outer periphery of the lower hoop body 1 according to the appropriate size of the leg circumference, and the buckle 7 drives the arc bar 8 to move downward, and the arc bar 8 pulls the elastic clamping block 9 downward to move. After the adjustment is completed, the elastic clamping block 9 is clamped with one of the multiple clamping grooves on the inner wall of the upper hoop frame 5, so that it is suitable for patients with different leg circumferences; Since the psychological burden of the patient is heavy during fracture reduction, it is necessary to massage and relax the patient after the operation. The embodiment of the present invention is used to squeeze the side frames from both sides to move the push plate 60. The push plate 60 pushes the rack 67 to work. The rack 67 moves and engages with the toothed disk 66 on the lower surface of the cushion layer 6. When the toothed disk 66 rotates, it drives the support column 62 to move. When the toothed disk 66 rotates, it drives the second rotating wheel 65 to move synchronously. The second rotating wheel 65 gradually massages the position of the leg between the lower hoop body 1 and the upper hoop frame 5. The movement of the support column 62 is linked to the synchronous movement of the diagonal support rod 63. The diagonal support rod 63 and the second rotating wheel 65 press on the human leg and rub the muscles, thereby reducing the tension of the human body, promoting the psychological comfort of the patient, and promoting blood circulation, thereby improving the comfort of the patient's legs.

[0029] Although different parts can be massaged, in order to improve the comfort level, when no massage is performed, the position of the side frame needs to be fixed to improve the squeezing and fixing effect on the fractured part. To this end, the electric telescopic rod 41 drives the moving parts on both sides to move, which drives the push block 44 to move, and the push block 44 drives the clamping head 45 to move. The clamping head 45 gradually moves toward the direction of the fixing part. During the insertion of the clamping head 45 into the bayonet, the clamping column 46 is squeezed into the mounting hole. At this time, the reset spring 47 is in a compressed state; when the groove is aligned with the clamping column 46, the reset spring 47 releases the elastic force to push the clamping column 46 out of the mounting hole and clamp it into the groove to form a lock, so that the positions of the two moving parts remain stable, thereby fixing the position of the side frame and improving the fixing effect on the fractured part; The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
