DETAILED DESCRIPTION

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] Reference Figure 1-11 , an adjustable limb fracture rapid external fixation device, comprising a main fixing bracket 1, a drawing groove 2 is arranged inside the main fixing bracket 1, and a movable seat mechanism 14 is slidably installed inside the drawing groove 2, an adjustment mechanism 8 is rotatably installed inside the movable seat mechanism 14, and a secondary fixing bracket 11 is rotatably installed at the bottom of the adjustment mechanism 8, the secondary fixing bracket 11 is plug-in-plug connected with the drawing groove 2, and a plurality of positioning grooves 18 cooperating with the adjustment mechanism 8 are arranged on the bottom inner wall of the drawing groove 2;

[0032] An upper limb fixing plate 3 is provided on the side of the main fixing bracket 1, and a plurality of upper nail holes 5 are provided on the surface of the upper limb fixing plate 3. A plurality of rectangular grooves 7 are provided on the outer side of the main fixing bracket 1, and upper limb fixing straps 4 are stored inside the rectangular grooves 7 at both ends, and two layers of storage boxes 6 are clamped inside the rectangular groove 7 in the middle, and a fixing nail 17 and a rotating tool are clamped inside each layer of the storage box 6;

[0033] A plurality of lower nail holes 12 are arranged in the middle of the auxiliary fixing bracket 11 , and strip grooves 10 are arranged on both sides of the auxiliary fixing bracket 11 , and foldable lower limb fixing straps 9 are arranged inside the strip grooves 10 , and the outer surface of the auxiliary fixing bracket 11 is covered with a protective film 13 .

[0034] In the present invention, the secondary fixing bracket 11 is installed inside the main fixing bracket 1 by plugging and unplugging through the movable seat mechanism 14 and the adjustment mechanism 8, and the straps used to restrain the limbs are stored in the secondary fixing bracket 11 and the side positions of the main fixing bracket 1. All the first aid for fractures is summarized inside the device for easy and quick access. When used in an emergency, the secondary fixing bracket 11 is pulled out from the lower end of the main fixing bracket 1, and the adjustment mechanism 8 is rotated so that the two ends of the adjustment mechanism 8 are embedded in the positioning groove 18, and the secondary fixing bracket 11 and the main fixing bracket 1 are fixed in a plane position. The secondary fixing bracket 11 and the main fixing bracket 1 form a support frame for fixing the injured person's legs. Afterwards, the upper limb fixing strap 4 and the lower limb fixing strap 9 are taken out from the sides of the main fixing bracket 1 and the secondary fixing bracket 11 respectively, and the Velcro on the surface of the strap is used to quickly tighten the legs to clamp them. The inside of the support frame and the adjusting mechanism 8 are kept at the knee joint of the leg, eliminating the need for bandage wrapping and fixing, shortening the first aid time for fractures. At this time, the auxiliary fixing bracket 11 and the main fixing bracket 1 can rotate around the center of the adjusting mechanism 8, and the upper and lower limbs of the leg can move forward and backward, which is convenient for the movement of patients with minor fractures. When bone screws are needed for leg fractures, the storage box 6 is pulled out, the fixing nails 17 and the rotating tool are taken out, and the fixing nails 17 are inserted into the corresponding nail holes. The support frame is fixed on the leg with the fixing nails 17, and the fracture site is fixed. Then the adjusting mechanism 8 is rotated again to form a fixed structure between the auxiliary fixing bracket 11 and the main fixing bracket 1, avoiding the movement of the patient's knee, completing rapid first aid in wartime, and allowing people to continue walking. The two fracture first aid fixation methods facilitate the walking transfer of the wounded in wartime after first aid to the greatest extent.

[0035] As a further solution in the present invention, the secondary fixing bracket 11 includes a ring body 111 clamped between the adjusting mechanism 8 and the movable seat mechanism 14, and a lower limb fixing splint 112 arranged at the bottom of the ring body 111, the lower nail hole 12 is arranged at the surface position of the lower limb fixing splint 112, and the inner wall of the ring body 111 is provided with a locking groove 113 which is engaged with the adjusting mechanism 8. In the present invention, when the secondary fixing bracket 11 is pulled out, the adjusting mechanism 8 is rotated one circle, only the fixation between the movable seat mechanism 14 and the main fixing bracket 1 is completed, so that the secondary fixing bracket 11 can be rotated with the bottom of the main fixing bracket 1 through the ring body 111. When the patient's leg is fixed in case of minor injuries, the knee joint of the patient's leg can move freely. When the patient is seriously injured, the adjusting mechanism 8 is rotated again to the maximum position. At this time, the adjusting mechanism 8 is embedded in the locking groove 113, and the secondary fixing bracket 11 and the main fixing bracket 1 are fixed in a straight line structure, which effectively restrains the knee joint of the patient's leg and constitutes an effective auxiliary support for the patient's leg, facilitating the patient's movement.

[0036] As a further solution in the present invention, the adjustment mechanism 8 includes two positioning pins 82 slidably connected to the movable seat mechanism 14, and an adjusting disk 81 rotatably connected to the movable seat mechanism 14. An adjusting gear 84 is installed at the bottom of the adjusting disk 81, and the interiors of the two positioning pins 82 are both provided with tooth grooves 85 meshing with the adjusting gears 84. In the present invention, when the movable seat mechanism 14 follows the auxiliary fixed bracket 11 to be pulled to the lowermost position, the adjusting disk 81 is rotated to drive the two positioning pins 82 to move outward through the adjusting gears 84 and the tooth grooves 85. The positioning pins 82 extend out of the movable seat mechanism 14 and are inserted into the positioning grooves 18, thereby completing the fixing operation of the movable seat mechanism 14. The operation is simple and convenient.

[0037] As a further solution in the present invention, the movable seat mechanism 14 includes an annular bracket 141, the interior of the annular bracket 141 is provided with an annular groove 143 rotatably connected to the ring body 111, and a guide groove 142 slidably connected to the positioning pin 82. In the present invention, the auxiliary fixed bracket 11 cooperates with the annular groove 143 and the ring body 111, so that the auxiliary fixed bracket 11 and the main fixed bracket 1 can rotate 0-20° forward and backward, thereby avoiding affecting the movement of the knee joint of the lightly injured patient.

[0038] As a further solution in the present invention, a locking tongue 83 engaged with the locking groove 113 is provided on the side of the positioning pin 82, and a rectangular through groove 144 matching the locking tongue 83 and the locking groove 113 is provided at the bottom of the annular bracket 141. In the present invention, when the adjusting disk 81 is continuously rotated, the locking tongue 83 located below the positioning pin 82 is embedded in the locking groove 113, completing the locking action between the ring body 111 and the annular bracket 141, so that the auxiliary fixed bracket 11 and the main fixed bracket 1 are quickly fixed to form a linear support structure, which is convenient for the overall restraint of the patient's legs and better fixation and protection of the legs of severely fractured patients.

[0039] As a further solution of the present invention, an upper protection pad 15 is provided on the outer side of the upper limb fixing plate 3, and the outer side of the upper protection pad 15 is covered with a protective layer. The upper protection pad 15 includes a strip protection pad 151 made of elastic material, and arc-shaped side wings 153 are provided on both sides of the strip protection pad 151. An upper through hole 152 matching the upper nail hole 5 is provided in the middle of the strip protection pad 151. In the present invention, the upper protection pad 15 is in contact with the injured person's leg, and the upper protection pad 15 made of elastic material is in contact with the skin, so as to reduce the pressure on the blood vessels of the leg and avoid the leg from being injured. The side wings 153 of the multiple arc-shaped structures form multiple indentations on the legs, which increases the friction between the device and the legs and improves the stability of the device when the legs are restrained. The side wings 153 locally compress the legs to maintain blood circulation in the legs. At the same time, the upper protective pad 15 absorbs disinfectant. When the injured person needs to be fixed with bone screws, the protective layer is removed. When the upper protective pad 15 is under pressure, the disinfectant inside is squeezed out to disinfect the area around the nail holes of the injured person, avoid local blood flow and cause the device to slip, and improve the stability of the injured person's leg fixation.

[0040] As a further solution in the present invention, a lower protective pad 16 is adhered to the bottom of the auxiliary fixing bracket 11, and the outer side of the lower protective pad 16 is covered with a protective layer. The lower protective pad 16 includes a lower strip protective pad 161 made of elastic material, and a lower through hole 162 matching the lower nail hole 12 is provided in the middle of the lower strip protective pad 161. In the present invention, the lower protective pad 16 is in contact with the injured person's leg, and the lower protective pad 16 made of elastic material is in contact with the skin to reduce pressure on the blood vessels in the leg and avoid friction damage to the leg. At the same time, disinfectant is absorbed in the lower protective pad 16. When the injured person needs to be fixed with bone screws, the protective layer is removed. When the lower protective pad 16 is pressurized, the disinfectant inside is squeezed out to disinfect the area around the nail hole of the injured person, compress and protect the wound, and absorb the blood oozing from the wound to avoid the blood affecting the restraint stability between the device and the limb.

[0041] As a further solution in the present invention, the secondary fixing bracket 11 is provided with an isolation groove 114 at the edge of the strip groove 10, and the two sides of the lower strip pad 161 are provided with extension portions 163 corresponding to the strip groove 10. In the present invention, the setting of the isolation groove 114 increases the elasticity of the connection between the strip groove 10 and the secondary fixing bracket 11. When the lower limb fixing strap 9 restrains the calf of the injured person, the strip groove 10 area deforms inward. At this time, the strip groove 10 drives the corresponding extension portion 163 to be C-shaped under the action of tension, thereby effectively fixing the calf of the injured person, making the fixation between the device and the calf of the injured person more stable and reliable.

[0042] When in use, in emergency use, the secondary fixing bracket 11 is pulled out from the lower end of the main fixing bracket 1, and the adjusting mechanism 8 is rotated so that the two ends of the adjusting mechanism 8 are embedded in the positioning grooves 18, and the secondary fixing bracket 11 is fixed to the main fixing bracket 1 in a plane position. The secondary fixing bracket 11 and the main fixing bracket 1 constitute a support frame for fixing the injured person's legs. After that, the upper limb fixing strap 4 and the lower limb fixing strap 9 are taken out from the sides of the main fixing bracket 1 and the secondary fixing bracket 11 respectively, and the Velcro on the surface of the strap is used to quickly tighten the leg to clamp the leg inside the support frame, and the adjusting mechanism 8 is kept at the knee joint of the leg, eliminating the need for bandage winding and fixation, shortening the first aid time for fractures, and the secondary fixing bracket 11 is used to fix the injured person's legs. The frame 11 and the main fixing bracket 1 can rotate around the center of the adjusting mechanism 8, and the upper and lower limbs of the leg can move forward and backward, which is convenient for the movement of patients with minor fractures. When bone screws are needed for leg fractures, the storage box 6 is pulled out, the fixing nails 17 and the rotating tool are taken out, and the fixing nails 17 are inserted into the corresponding nail holes. The fixing nails 17 are used to fix the support frame on the leg and fix the fracture site. Then, the adjusting mechanism 8 is rotated again to form a fixed structure between the auxiliary fixing bracket 11 and the main fixing bracket 1 to avoid movement of the patient's knee, complete the rapid first aid in wartime, and allow people to continue walking. The two fracture first aid fixation methods facilitate the walking transfer of the wounded in wartime to the greatest extent after first aid.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
