Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an orthodontic correction device for a leg. Background Art

[0002] Orthodontic devices for the legs are devices used for long-term fixation or correction of fractured or deformed bones. Orthodontics can help correct these problems to promote normal growth and development of the legs. Orthodontic devices for the legs are medical devices used to correct leg deformities or dysfunctions. These devices are suitable for various leg problems. As a type of orthodontic device for the legs, the Ibrahim brace is an external fixation device mainly used for fracture repair, bone lengthening and bone deformity correction, etc. It consists of several annular metal frames and connecting rods, which can stably support damaged bones.

[0037] In this embodiment, when a patient needs leg correction, first, an I-style frame for orthodontic correction of the patient's leg is placed on a workbench, and then the patient who needs surgery is subjected to corresponding anesthesia and disinfection preparations, and the part of the patient's leg that needs correction is placed in the corresponding position. When all preparations are completed, the vertical rod 104 used to fix the patient's leg bone is inserted into the position of the corresponding bone, and then the tightening bolt 103 corresponding to the vertical rod 104 is inserted into the corresponding positioning block 102, and the positioning block 102 is moved to the corresponding position, so that the vertical rod 104 is embedded in the arc groove 109 in the tightening bolt 103, and the vertical rod 104 is positioned, and then the nut 105 corresponding to the tightening bolt 103 is sleeved on the outer surface of the tightening bolt 103, and when the outer surface of the nut 105 is rotated to a position that is tightly fitted with the outer surface of the gasket 110, the fixation of the vertical rod 104 is completed, wherein, as Figure 4As shown, the outer surface of the gasket 110 is frosted and has multiple protrusions on the surface. The purpose is to limit the nut 105 to prevent movement. Then, the other vertical rods 104 on the limiting ring 101 can be inserted into the patient's body in the same way and fixed. The position of each positioning block 102 on the limiting ring 101 is set in advance and corresponds to the position where the patient needs to insert the vertical rod 104. When the vertical rod 104 on the limiting ring 101 is completely fixed, first, multiple screw rods 107 are respectively inserted into the interior of multiple mounting blocks 106 in the limiting ring 101, and then multiple screw sleeves 108 are respectively sleeved at the connection between each screw rod 107 and the multiple mounting blocks 106, and the screw sleeves 108 are rotated until the outer surface of the screw sleeve 108 is in tight contact with the outer surface of the corresponding mounting block 106, and then the first connecting sleeve 201 can be as Figure 8 The smooth upward sleeve shown is set between the outer surfaces of a part of the screw rod 107, and then the second connecting sleeve 202 with the raised side is inserted into the outer surface of the other part of the screw rod 107, so that the raised part of the second connecting sleeve 202 is inserted into the rectangular groove of the first connecting sleeve 201, thereby realizing the connection between the first connecting sleeve 201 and the second connecting sleeve 202, so that the two are assembled into a circular ring, thereby installing the protective component 3 between the outer surfaces of multiple screw rods 107, and then the mounting blocks 106 in another limiting ring 101 can be rotated to the positions corresponding to the multiple screw rods 107, and then moved to the outer surfaces of the multiple screw rods 107, so The connection between another limiting ring 101 and the plurality of screw rods 107 is realized, and then the plurality of vertical rods 104 arranged on the surface of the limiting ring 101 can be inserted into the leg bones of the patient. When all the vertical rods 104 are installed, the first connecting sleeve 201 and the second connecting sleeve 202 are moved to the corresponding positions of the patient's legs, and the two sliding rings 306 are slid in the direction of the plurality of sliding rods 304 respectively, so that the plurality of rotating plates 303 are squeezed and rotated along the moving direction of the sliding rings 306 respectively. When the rotating plates 303 rotate to the position in contact with the outer surfaces of the plurality of protective blocks 310, the plurality of connecting rods 309 are squeezed toward the inside of the fixing ring 301, wherein, as Fig.11 As shown, the connecting rod 309 is inclined at the position corresponding to the rotating plate 303, and the outer diameter of the inclined block is larger than the hole diameter between the connecting rod 309 and the first connecting sleeve 201 and the second connecting sleeve 202, the purpose of which is to limit the protective block 310 and prevent it from moving out of the first connecting sleeve 201 and the second connecting sleeve 202. The rotating plate 303 drives the connecting rod 309 to move inward, and then drives the protective block 310 to move inward until the plurality of protective blocks 310 are in contact with the patient's legs, and the patient's legs are clamped and fixed, wherein, as shown in FIG. Fig.11As shown, the outer surface of the protection block 310 is provided with a plurality of protrusions, and all of them are made of silicone material. Silicone is soft and elastic, and is often used on the surface of massage pads or massage appliances. It can provide a comfortable touch and has anti-slip properties, so that the patient's legs will not feel uncomfortable during the clamping protection process. When the plurality of protection blocks 310 are all moved to the patient's legs, the sliding ring 306 just moves to the outer surface of the sliding rod 304, and at this time the positioning bolts 308 just move to the position corresponding to the circular hole on the surface of the connecting block 305, and the plurality of positioning bolts 308 can be rotated to drive One ends of multiple positioning bolts 308 are respectively inserted into the corresponding connecting blocks 305, thereby realizing the positioning of the slip ring 306, and then realizing the positioning of the rotating plate 303, and then realizing the positioning of the protective block 310, thereby realizing the connection between the leg orthodontic correction device and the patient's leg, thereby making the vertical rod 104 and the patient's leg remain stable, preventing the vertical rod 104 from being misplaced when the patient's leg moves, and solving the problem in the prior art that the I-style frame is easily offset when the patient's legs need to be shifted or the posture needs to be adjusted, affecting the self-healing effect of the patient's leg correction.

[0038] like Figure 1 and Figure 6 - Fig.11 As shown, the opposite outer surfaces of the first connecting sleeve 201 and the second connecting sleeve 202 are fixedly connected with four baffles 203 for limiting, and the eight baffles 203 are made of rubber material. The opposite outer surfaces of the second connecting sleeve 202 are provided with two limiting grooves 204 for positioning, and the interiors of the four limiting grooves 204 are rotatably connected to the limiting blocks 205, and one end of the four limiting blocks 205 is fixedly installed with a gear 206, and the outer surfaces of the four gears 206 are fixed with a rotating shaft 207, and the opposite outer surfaces of the second connecting sleeve 202 are fixedly connected with two fixing frames 208, and one end of the four rotating shafts 207 are respectively movably penetrated to the four fixed Outside the fixed frame 208, the outer surfaces of the four rotating shafts 207 are fixedly sleeved with a gear ring 210 near one end, the outer surfaces of the four fixed frames 208 are fixedly installed with rubber protrusions 209 for limiting, the insides of the four rubber protrusions 209 are respectively meshed with the outer surfaces of the four gear rings 210, the outer surfaces of the four gears 206 are meshed with the first tooth row 211, the outer surfaces of the four first tooth rows 211 slide with the inner walls of the four fixed frames 208 respectively, the outer surfaces of the four gears 206 are meshed with the second tooth row 212, the outer surfaces of the four second tooth rows 212 slide with the inner walls of the four fixed frames 208 respectively.

[0039] In this embodiment, after the first connecting sleeve 201 and the second connecting sleeve 202 form a circular ring sleeve and are arranged on the outer surface of the screw rod 107, the four rotating shafts 207 are rotated respectively to drive the limit block 205 to rotate, wherein, Fig. 9As shown, the cross-section of the limit block 205 matches the cross-section of the limit groove 204, and both are T-shaped. The purpose is to limit the limit block 205 and make it rotate with the rotation of the shaft 207. The shaft 207 drives the gear 206 to rotate, thereby driving the first tooth row 211 and the second tooth row 212 matched therewith to rotate. Fig.10 As shown, the first tooth row 211 and the second tooth row 212 are both stuck in the interior of the fixing frame 208, the purpose of which is to limit the first tooth row 211 and the second tooth row 212. The first tooth row 211 and the second tooth row 212 are driven by the rotation of the rotating shaft 207 to move to the opposite outside of the fixing frame 208 respectively. When the first tooth row 211 and the second tooth row 212 are in contact with the outer surface of the corresponding baffle 203 respectively, they cannot continue to move forward, and the rotation of the rotating shaft 207 can be stopped at this time. In addition, as shown in FIG. Fig.10 As shown, in order to limit the rotating shaft 207 and prevent it from rotating at will, the rotating shaft 207 drives the gear ring 210 to rotate during its rotation, and then drives the rubber protrusion 209 matched with it to be squeezed and deformed to be concave to the outside of the gear ring 210, so that the rotation of the gear ring 210 can be realized. When the gear ring 210 stops rotating, that is, stops squeezing the rubber protrusion 209, the rubber protrusion can be reset under the action of its own elastic force, and the gear ring 210 can be limited again, thereby preventing the rotation of the rotating shaft 207. When the outer surfaces of the four groups of first tooth rows 211 and second tooth rows 212 are all moved to the outer surface of the corresponding baffle 203, the fixed connection between the first connecting sleeve 201 and the second connecting sleeve 202 is achieved, thereby preventing the protective component 3 from being displaced during the process of fixing the human leg, and further improving the stability of the leg orthodontic device.

[0040] The method of use and working principle of the device are as follows: when a patient needs leg shape correction, the vertical rod 104 used to fix the patient's leg bones is inserted into the position of the corresponding bones, and then the tightening bolt 103 corresponding to the vertical rod 104 is inserted into the corresponding positioning block 102, and the positioning block 102 is moved to the corresponding position, so that the vertical rod 104 is embedded in the arc groove 109 in the tightening bolt 103, the vertical rod 104 is positioned, and then the nut 105 corresponding to the tightening bolt 103 is sleeved on the outer surface of the tightening bolt 103, when the outer surface of the nut 105 is rotated to a position tightly fitted with the outer surface of the gasket 110, the fixation of the vertical rod 104 is completed, and then the vertical rod 104 can be used. In the same way, the other vertical rods 104 on the limiting ring 101 are inserted into the patient's body in sequence and fixed, wherein the position of each positioning block 102 on the limiting ring 101 is set in advance and corresponds one by one to the position where the patient needs to insert the vertical rod 104. When the vertical rod 104 on the limiting ring 101 is completely fixed, firstly, a plurality of screw rods 107 are respectively inserted into the interior of a plurality of mounting blocks 106 in the limiting ring 101, and then a plurality of screw sleeves 108 are respectively sleeved at the connection between each screw rod 107 and a plurality of mounting blocks 106, and the screw sleeves 108 are rotated until the outer surface of the screw sleeve 108 is in tight contact with the outer surface of the corresponding mounting block 106, and then the first connecting sleeve 201 can be connected as shown in FIG. Figure 8 The smooth upward sleeve shown is set between the outer surfaces of a part of the screw rod 107, and then the second connecting sleeve 202 with the raised side is inserted into the outer surface of the other part of the screw rod 107, so that the raised part of the second connecting sleeve 202 is inserted into the rectangular groove of the first connecting sleeve 201, thereby realizing the connection between the first connecting sleeve 201 and the second connecting sleeve 202, so that the two are assembled into a circular ring, so that the protective component 3 is installed between the outer surfaces of multiple screw rods 107, and then the four rotating shafts 207 are rotated respectively, driving the limit block 205 to rotate, and then driving the gear 206 to rotate, thereby driving the first tooth row 211 and the second tooth row 212 matched therewith to rotate, as shown in FIG. Fig.10 As shown, the first tooth row 211 and the second tooth row 212 are both stuck in the interior of the fixed frame 208, and the first tooth row 211 and the second tooth row 212 are driven to move to the opposite exterior of the fixed frame 208 by the rotation of the rotating shaft 207. When the first tooth row 211 and the second tooth row 212 are in contact with the outer surface of the corresponding baffle 203, they cannot move forward any further, and the rotation of the rotating shaft 207 can be stopped at this time. Fig.10As shown, in order to limit the rotating shaft 207 and prevent it from rotating at will, the rotating shaft 207 drives the gear ring 210 to rotate during its rotation, thereby driving the rubber protrusion 209 matched therewith to be squeezed and deformed and concave to the outside of the gear ring 210, so that the rotation of the gear ring 210 can be realized. When the gear ring 210 stops rotating, that is, stops squeezing the rubber protrusion 209, the rubber protrusion can be reset under the action of its own elastic force, and the gear ring 210 can be limited again, thereby preventing the rotation of the rotating shaft 207. When the outer surfaces of the four groups of first tooth rows 211 and second tooth rows 212 are all moved to the outer surfaces of the corresponding baffles 203, the fixed connection between the first connecting sleeve 201 and the second connecting sleeve 202 is realized, and the protective component 3 is prevented from being displaced during the process of fixing the human leg. Then, another limiting ring can be placed. The mounting blocks 106 in 101 are rotated to positions corresponding to the plurality of screw rods 107, and then moved to the outer surfaces of the plurality of screw rods 107, thereby realizing the connection between another limiting ring 101 and the plurality of screw rods 107, and then the plurality of vertical rods 104 arranged on the surface of the limiting ring 101 can be inserted into the leg bones of the patient. When all the vertical rods 104 are installed, the first connecting sleeve 201 and the second connecting sleeve 202 are moved to positions corresponding to the patient's legs, and the two sliding rings 306 are slid in the direction of the plurality of sliding rods 304, respectively, so that the plurality of rotating plates 303 are squeezed and rotated in the direction of movement of the sliding rings 306. When the rotating plates 303 are rotated to a position in contact with the outer surfaces of the plurality of protective blocks 310, the plurality of connecting rods 309 are squeezed toward the inside of the fixing ring 301, wherein, as Fig.11 As shown, the connecting rod 309 is inclined at the position corresponding to the rotating plate 303, and the outer diameter of the inclined block is larger than the hole diameter between the connecting rod 309 and the first connecting sleeve 201 and the second connecting sleeve 202, the purpose of which is to limit the protective block 310 and prevent it from moving out of the first connecting sleeve 201 and the second connecting sleeve 202. The rotating plate 303 drives the connecting rod 309 to move inward, and then drives the protective block 310 to move inward until multiple protective blocks 310 are in contact with the patient's legs, and the patient's legs are clamped and fixed. Fig.11As shown, the outer surface of the protective block 310 is provided with a plurality of protrusions, and all of them are made of silicone material. Silicone has softness and elasticity. When the plurality of protective blocks 310 are moved to the patient's legs, the slip ring 306 just moves to the outer surface of the slide rod 304, and at this time, the positioning bolt 308 just moves to the position corresponding to the circular hole on the surface of the connecting block 305, and the plurality of positioning bolts 308 can be rotated to drive one end of the plurality of positioning bolts 308 to be inserted into the corresponding interior of the connecting block 305, thereby realizing the positioning of the slip ring 306, and then realizing the positioning of the rotating plate 303, and then realizing the positioning of the protective block 310, thereby realizing the connection between the leg orthodontic correction device and the patient's leg, and then making the vertical rod 104 and the patient's leg remain stable.
