Description

Technical Field

[0001] The invention belongs to the technical field of fracture reduction, in particular to a fracture reduction device. Background Art

[0002] A fracture refers to a complete or partial break in the continuity of a bone structure. A fracture is a disease in which a bone is partially or completely broken due to trauma or pathology. Its main clinical manifestations are localized pain and tenderness at the fracture site, local swelling and ecchymosis, and partial or complete loss of limb function. Complete loss fractures may also cause limb deformities and abnormal movements. After a fracture, the patient needs to undergo reduction treatment to promote healing and reduce deformities. Among them, tibial and fibular shaft fractures are the most common fracture types in clinical practice.

[0003] Currently, tibia and fibula shaft fractures are mainly treated by fracture reduction robots that continuously traction the bones to maintain the stability of the fracture ends, reduce and combine the two ends of the bone, and promote smooth healing of the fracture. However, each patient's leg circumference is different, making it difficult to fix the leg circumference of different patients, which is not conducive to better fracture reduction treatment. Summary of the Invention

[0006] Furthermore, a massage component is installed on the lower surface of the cushion layer, and the massage component is connected to the side frame. The multiple upper plates include a fixed part and two movable parts slidably arranged at the end of the main shaft. Electric telescopic rods are provided at both ends of the fixed part for driving the two movable parts to move.

[0007] Furthermore, a straight frame is installed between the two end portions of the two side frames. The straight frame includes a fixed block and two movable blocks slidably arranged at both ends of the fixed block. Guide rods are arranged at both ends of the fixed block. The two movable blocks are slidably connected to the guide rods.

[0008] Furthermore, the main shaft consists of two parts: a shell and a shaft body, and a torsion spring is provided between the shaft body and the shell.

[0009] Furthermore, the cushion layer is slidably connected to the straight frame, the cushion layer is made of elastic material, and the massage component is used to press down and gently knead the area around the patient's fracture. The massage component includes a main support bar installed under the cushion layer, and the main support bar is penetrated by a plurality of support columns, and the support columns are penetrated by an oblique support rod, and both ends of the oblique support rod are fixedly connected to a first rotating wheel, and both ends of the plurality of support columns are respectively fixedly connected to a second rotating wheel and a gear disk, and a push plate is fixedly connected to the side of the side frame close to the cushion layer, and a rack is fixedly connected to the side of the push plate.

[0010] Furthermore, the rack is meshed with the gear disc.

[0011] Furthermore, a plurality of soft rubber heads are installed on the top of the second rotating wheel.

[0012] Furthermore, a stabilizing component is installed on the side of the two movable parts close to the fixed part, and the stabilizing component includes a push block, the end of the push block is fixedly connected to a clamping head, a groove is provided on the side of the clamping head, and a bayonet is provided at both ends of the fixed part.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The fracture reduction device described in the present invention pushes the rack to work by a push plate. The movement of the rack will engage with the toothed disc on the lower surface of the cushion layer. When the toothed disc rotates, it drives the support column to move. When the toothed disc rotates, it drives the second rotating wheel to move synchronously. The second rotating wheel gradually massages the position of the leg between the lower hoop body and the upper hoop frame. The movement of the support column is linked to the synchronous movement of the diagonal support rod. The pressing of the human leg and the kneading of the muscles by the diagonal support rod and the second rotating wheel can reduce the tension of the human body, promote the psychological comfort of the patient, and at the same time promote blood circulation and accelerate the comfort of the patient's legs.

[0017] 2. The fracture reduction device described in the present invention drives the moving parts on both sides to move by the electric telescopic rod, which drives the push block to move, and the push block drives the clamping head to move, and the clamping head gradually moves toward the direction of the fixed part. During the process of inserting the clamping head into the bayonet, the clamping column is squeezed into the mounting hole.

The upper hoop frame 5 is a hollow structure, and an arc bar 8 is slidably connected to the inside of the upper hoop frame 5. A plurality of elastic blocks 9 are installed between the outside of the arc bar 8 and the upper hoop frame 5. The inner wall of the upper hoop frame 5 is provided with a plurality of card grooves corresponding to the plurality of elastic blocks 9, and a buckle 7 is fixed to the end of the arc bar 8; a lock core cooperating with the buckle 7 is provided inside the lower hoop body 1, and three lock holes are opened on the outer periphery of the lower hoop body 1.

[0031] During operation, 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 patient's fracture position. 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 The fibula is aligned with the bottom of the pad 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 embodiment of the present invention is used to gradually press the buckle 7 downward again, 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 slots on the inner wall of the upper hoop frame 5, so that it is suitable for patients with different leg circumferences.

[0032] like Figures 3 and 4As 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 guide rods 40 are provided at both ends of the fixed block, and the two movable blocks are slidably connected to the guide rods 40; the main shaft 3 consists of two parts, an outer shell and a shaft body, and a torsion spring is provided 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.

[0033] 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, and then drives the two moving blocks of the straight frame to move back and forth, and further drives the two side frames to move back and forth, thereby driving the massage component to work and realize massaging 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.

[0034] like Figures 3 to 5 As shown, the cushion layer 6 is slidably connected to the straight frame, and the cushion layer 6 is made of elastic material. The massage component is used to press down and gently knead the area around the patient's fracture. The massage component includes a main support bar 61 installed under the cushion layer 6, and 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, and both ends of the oblique support rod 63 are fixedly connected to a rotating wheel 1 64, and the two ends of the plurality of support columns 62 are respectively fixedly connected to a rotating wheel 2 65 and a toothed disk 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 disk 66; a plurality of soft rubber heads are installed on the top of the rotating wheel 2 65;

[0035] During operation, since the patient has a heavy psychological burden when the fracture is reduced, it is necessary to perform massage and relaxation treatment on 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 disc 66 on the lower surface of the cushion layer 6. When the toothed disc 66 rotates, it drives the support column 62 to move. When the toothed disc 66 rotates, it drives the second wheel 65 to move synchronously. The second 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 pressing of the human leg and the kneading of the muscles by the diagonal support rod 63 and the second wheel 65 can reduce the tension of the human body, promote the psychological comfort of the patient, and promote blood circulation, thereby improving the comfort of the patient's legs.

[0036] like Figures 7 to 9 As shown, a stabilizing component is also installed on the 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 bayonet is provided at both ends of the fixed part. The inner wall of the bayonet is provided with a mounting hole, 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.

[0037] During operation, although different parts of the body can be massaged, in order to improve comfort, when not massaging, the position of the side frames needs to be fixed to improve the squeezing and fixing effect on the fractured parts. 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. 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 return spring 47 is in a compressed state; when the groove is aligned with the clamping column 46, the return 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 frames and improving the fixing effect on the fractured part.

[0038] 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, thereby allowing the two moving parts to move back and forth.

[0039] 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 fracture to complete the reduction, so as to promote the recovery of the patient's fracture position. When the patient needs to undergo rapid recovery treatment, the embodiment of the present invention is used. First, the device is applied to the scene of fracture reduction at the tibia and fibula. First, the upper hoop frame 5 is flipped to one side. 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 bottom of the pad layer 6, and then the upper hoop frame 5 is closed. With continued use, when the leg circumference of the patient varies and needs to be adjusted, the buckle 7 is gradually pressed downward again using the embodiment of the present invention. The buckle 7 is locked in one of the three lock holes on the outer periphery of the lower hoop body 1 according to the appropriate leg circumference size. The buckle 7 drives the arc bar 8 to move downward, and the arc bar 8 pulls the elastic block 9 downward to move. After the adjustment is completed, the elastic block 9 is engaged with one of the multiple slots on the inner wall of the upper hoop frame 5, thereby adapting to patients with different leg circumferences.

[0040] Since the psychological burden of patients is heavy during fracture reduction, it is necessary to perform massage and relaxation treatment on the patients 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 movement of the rack 67 will engage with the toothed disc 66 on the lower surface of the cushion layer 6. When the toothed disc 66 rotates, it drives the support column 62 to move. When the toothed disc 66 rotates, it drives the second wheel 65 to move synchronously. The second 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 pressing of the human leg and the kneading of the muscles by the diagonal support rod 63 and the second wheel 65 can reduce the tension of the human body, promote the psychological comfort of the patient, and promote blood circulation, thereby improving the comfort of the patient's legs.

[0041] Although different parts can be massaged, in order to improve comfort, when no massage is performed, the position of the side frames needs to be fixed to improve the squeezing and fixing effect on the fractured parts. 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. 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 return spring 47 is in a compressed state; when the groove is aligned with the clamping column 46, the return 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 frames and improving the fixing effect on the fractured part.
