Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to an adjustable rapid external fixation device for limb fractures. Background Art

[0002] Fractures are usually serious traumas. Therefore, on-site first aid should not only pay attention to the treatment of fractures, but more importantly, pay attention to the treatment of the whole body. The purpose is to use the simplest and most effective method to save lives, protect the affected limbs, and quickly transfer them so that they can be properly treated as soon as possible. Fixation is an important measure for first aid for fractures. First aid for fractures can fix the limbs through splints, etc., to avoid damage to surrounding important tissues such as blood vessels, nerves, and internal organs during transportation by the fracture ends; and reduce the activity of the fracture ends to relieve the patient's pain.

[0003] In the field, when a person suffers a leg fracture, an adjustable first aid fixation device for leg fractures is used. This device is fixed to the leg with steel nails, allowing the person to continue walking. However, most of these devices currently have a simple splint structure, which requires a bandage to fix and bandage the fracture site. This takes a long time and the steps are complicated. The fracture cannot be quickly repositioned and fixed. Moreover, the surface of the steel plate or splint is flat.

DETAILED DESCRIPTION

[0030] The following describes embodiments of the present invention in detail. Examples of the embodiments 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] Reference Figure 1-11 , an adjustable rapid external fixation device for limb fractures, including a main fixing bracket 1, a drawing slot 2 is provided inside the main fixing bracket 1, and a movable seat mechanism 14 is slidably installed inside the drawing slot 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 plugged and unplugged with the drawing slot 2, and the bottom inner wall of the drawing slot 2 is provided with multiple groups of positioning grooves 18 that cooperate with the adjustment mechanism 8;

[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 outside of the main fixing bracket 1, and the upper limb fixing straps 4 are accommodated in the rectangular grooves 7 at both ends. Two layers of storage boxes 6 are clamped in the interior of the rectangular groove 7 in the middle, and a fixing nail 17 and a rotating tool are clamped in the interior of each layer of the storage box 6.

[0033] A plurality of lower nail holes 12 are provided in the middle of the secondary fixing bracket 11, and strip grooves 10 are provided on both sides of the secondary fixing bracket 11. The interior of the strip grooves 10 is provided with foldable lower limb fixing straps 9, and the outer surface of the secondary 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 all stored in the secondary fixing bracket 11 and the side positions of the main fixing bracket 1. All the materials needed for first aid of fractures are summarized inside the device for quick access. In emergency use, 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 straps 4 and the lower limb fixing straps 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 straps is used to quickly tighten the legs to clamp them. The support frame is inside and the adjustment mechanism 8 is kept at the knee joint of the leg, eliminating the need for bandage wrapping and fixation, shortening the first aid time for fractures. At this time, the secondary fixing bracket 11 and the main fixing bracket 1 can rotate around the center of the adjustment mechanism 8, and the upper and lower limbs of the leg can move forward and backward, which is convenient for patients with minor fractures to move. When encountering a leg fracture that requires the use of bone screws, 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 adjustment mechanism 8 is rotated again to form a fixed structure between the secondary fixing bracket 11 and the main fixing bracket 1, avoiding the movement of the patient's leg knee, completing wartime rapid first aid, and allowing people to continue walking. The two fracture first aid fixation methods facilitate the wartime wounded to walk and transfer 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, and 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 slightly injured, 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, fixing the secondary fixing bracket 11 and the main fixing bracket 1 in a straight structure, effectively restraining the knee joint of the patient's leg, and forming an effective auxiliary support for the patient's leg, making it convenient for the patient to move.

[0036] As a further solution in the present invention, the adjustment mechanism 8 includes two positioning pins 82 that are slidingly connected to the movable seat mechanism 14, and an adjusting disk 81 that is rotatably connected to the movable seat mechanism 14. An adjusting gear 84 is installed at the bottom of the adjusting disk 81, and the interior of the two positioning pins 82 is provided with a tooth groove portion 85 that meshes with the adjusting gear 84. In the present invention, when the movable seat mechanism 14 follows the auxiliary fixed bracket 11 and is pulled to the lowest position, the adjusting disk 81 is rotated to drive the two positioning pins 82 to move outward through the adjusting gear 84 and the tooth groove portion 85. The positioning pin 82 extends out of the movable seat mechanism 14 and is inserted into the positioning groove 18, 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, and 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° back and forth, thereby avoiding affecting the movement of the knee joint of patients with minor injuries.

[0038] As a further solution in the present invention, a locking tongue 83 is provided on the side of the positioning pin 82 and is engaged with the locking groove 113, and a rectangular through groove 144 is provided on the bottom of the annular bracket 141 and is matched with the locking tongue 83 and the locking groove 113. 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 secondary fixing bracket 11 and the main fixing 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 patients with severe fractures.

[0039] As a further solution in the present invention, an upper protective pad 15 is provided on the outer side of the upper limb fixation plate 3, and the outer side of the upper protective pad 15 is covered with a protective layer. The upper protective pad 15 includes a strip protective pad 151 made of elastic material, and both sides of the strip protective pad 151 are provided with arc-shaped side wings 153, and the middle of the strip protective pad 151 is provided with an upper through hole 152 that matches the upper nail hole 5. In the present invention, the upper protective pad 15 is in contact with the injured person's leg, and the upper protective pad 15 of elastic material is in contact with the skin, thereby reducing the pressure on the leg blood vessels and avoiding leg injuries. 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 nails, 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 secondary 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 the middle part of the lower strip protective pad 161 is provided with a lower through hole 162 that cooperates with the lower nail hole 12. 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 the pressure on the leg blood vessels and avoid friction damage to the leg. At the same time, the lower protective pad 16 absorbs disinfectant. When the injured person needs to be fixed with bone screws, the protective layer is removed. When the lower protective pad 16 is under pressure, the disinfectant inside is squeezed out to disinfect the area around the injured person's nail hole, compress and protect the wound, and absorb the blood oozing from the wound to avoid 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 extension portions 163 corresponding to the strip groove 10 are provided on both sides of the lower strip pad 161. 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 injured person's calf, 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 injured person's calf, making the fixation between the device and the injured person's calf more stable and reliable.

[0042] When in use, for 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 and the main fixing bracket 1 are fixed 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. 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 leg to clamp the leg inside the support frame, and keep the adjusting mechanism 8 at the knee joint of the leg, eliminating the need for bandage wrapping and fixation, shortening the first aid time for fractures, and at this time, the secondary fixing bracket 11 is fixed. 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 legs can move forward and backward, which is convenient for the movement of patients with minor fractures. When a leg fracture requires the use of bone screws, 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 secondary fixing bracket 11 and the main fixing bracket 1, avoiding movement of the patient's leg knee, completing wartime rapid first aid, and allowing people to continue walking. The two fracture first aid fixation methods facilitate the wartime wounded to walk and transfer after first aid to the greatest extent.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
