[0002] A fracture fixation device is a medical device used to fix the fracture site to facilitate healing. Common fracture fixation devices include plaster splints, external fixators, internal fixation plates and screws, etc. These devices can help fracture healing and reduce pain by fixing and supporting the fracture site, while protecting the surrounding soft tissues.

[0003] Patent document CN202123213155.8 discloses a leg fracture fixation device, "comprising two arc-shaped outer plates that can form a cylindrical shape when interlocked, and a plurality of fixing components distributed along the axial direction of the arc-shaped outer plate are connected to the arc-shaped outer plate, and a medicine-loading component is detachably installed between two adjacent fixing components. A plurality of fixing components are arranged on the arc-shaped outer plate of the utility model, and a medicine-loading component can be movably installed between two adjacent fixing components. When changing the dressing for the patient, it is only necessary to pull out the medicine-loading component, reload the new medicine, and then insert the medicine-loading component back between the two fixing components. The entire dressing change process does not require the removal of the entire fixing device, which can effectively avoid secondary injuries caused by the movement of the patient's legs during the dressing change process."

[0030] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a fracture fixation device, including an outer guard plate 1, both sides of the left outer guard plate 1 are fixedly connected with a support frame 2, the interior of the support frame 2 is slidably connected with a connecting plate 11, an adjustment fixing component is installed inside the support frame 2, the inner side of the outer guard plate 1 is fitted with an inner steel plate 7, the inner side of the inner steel plate 7 is provided with a mounting groove 15, the interior of the mounting groove 15 is fixedly connected with a protective cotton layer 9, the top of the inner steel plate 7 is fixedly connected with a disassembly arc plate 6, and the top of the outer guard plate 1 is fixedly connected with both sides. Limiting column 8, a rotating installation component is installed at the bottom end of the outer guard plate 1, and the adjustment and fixing component includes a threaded rod 5, and the outer left side of the threaded rod 5 is fixedly connected with an anti-dropping sheet 4, and the left middle part of the support frame 2 is rotatably connected with an adjusting sleeve 3, and the inner two ends of the outer guard plate 1 are connected by a plurality of adjusting springs 10, and the inner side of the adjusting sleeve 3 is threadedly connected to the outer side of the threaded rod 5, and the right side of the threaded rod 5 is respectively fixedly connected to the left side of the connecting plate 11, and the right side of the connecting plate 11 is respectively fixedly connected to the inner two ends of the right outer guard plate 1;

[0033] When installing the patient's leg, pinch the adjusting sleeves 3 on both sides and rotate them at the same time. As the inner thread of the adjusting sleeve 3 contacts the outer thread of the threaded rod 5, the threaded rod 5 is moved to the right. As the threaded rod 5 moves to the right, the connecting plate 11 is pushed outward inside the support frame 2, thereby separating the distance between the outer guard plates 1. When the anti-slip sheet 4 contacts the outer side surface of the adjusting sleeve 3, the movement of the threaded rod 5 is restricted. At this time, the expansion range between the outer guard plates 1 is the largest. The injured part is put into the circle, and the device is moved to the injured part. The adjusting sleeve 3 is rotated in the opposite direction at the same time, so that the threaded rod 5 moves to the left, and the connecting plate 11 is retracted into the interior of the support frame 2. The opening and closing of the outer guard plates 1 on both sides are restricted between the support frame 2 and the connecting plate 11 to avoid deviation. The adjusting sleeve 3 is rotated until the protective cotton layers 9 on both sides are close to the injured part, thereby fixing the injured part, so that the device can fit the fracture of patients with different body shapes, thereby ensuring the wide applicability of the device and making it more convenient to use.

[0034] Reference Figure 2 , Figure 3 and Figure 4 The rotating installation assembly includes a rotating column 16, a plurality of limit rings 18 are fixedly connected to the outer upper side of the rotating column 16, a mounting column 19 is fixedly connected to the inner side of the rotating column 16, a soft rubber ring 17 is fixedly connected to the bottom end of the outer guard plate 1, a rotating handle 12 is fixedly connected to the bottom end of the rotating column 16, and a mounting frame 13 is fixedly connected to the bottom end of the inner steel plate 7. The outer parts of the rotating column 16 are respectively rotatably connected to the bottom end of the outer guard plate 1, the inner sides of the soft rubber rings 17 are attached to the outer parts of the rotating column 16, the outer parts of the mounting columns 19 are nested in the inner parts of the mounting frame 13, the outer parts of the limit columns 8 are respectively correspondingly inserted into the inner parts of the disassembly arc plates 6, and the outer parts of the limit rings 18 are respectively rotatably connected to the inner bottom sides of the outer guard plates 1;

[0035] When the internal cushion needs to be cleaned, the rotating handle 12 is rotated outward to disengage the mounting column 19 from the mounting frame 13, thereby the inner steel plate 7 loses its fixing condition and the rotating column 16 rotates, and the soft rubber ring 17 generates an extrusion force on the rotating column 16 to stabilize the rotation direction of the rotating column 16. At the same time, the limiting ring 18 rotates inside the outer guard plate 1 as the rotating column 16 rotates. The limiting ring 18 limits the rotating column 16 inside the outer guard plate 1 to improve stability. At this time, the arc plate 6 is disassembled and pulled upward by pulling out the notch on the outside. The limiting column 8 is disengaged from the hole inside the disassembled arc plate 6 to remove the inner steel plate 7 for cleaning. The internal cushion can be removed for cleaning, which is convenient for cleaning the cotton layer of the internal cushion to avoid excessive dirt accumulation affecting the skin surface and causing infection.

[0036] Reference Figure 1 and Figure 3 The outer side of the outer guard plate 1 is evenly provided with a plurality of holes, and the inner side steel plate 7 is evenly provided with a plurality of ventilation slots 14;

[0037] The air inside the device can circulate through the outer holes of the outer protective plate 1 and the ventilation slots 14, thereby preventing the protective cotton layer 9 from generating stuffiness to the skin and causing skin itching, thereby improving the ventilation effect and the wearing comfort.

[0038] Working principle: When installing the patient's leg, pinch the adjusting sleeves 3 on both sides and rotate them at the same time, so that the threaded rod 5 moves to the right. As the threaded rod 5 moves to the right, the connecting plate 11 is pushed outward from the inside of the support frame 2, thereby separating the distance between the outer guard plates 1, and the injured part is put into the circle. Move the device to the injured part, and rotate the adjusting sleeve 3 in the opposite direction at the same time, so that the threaded rod 5 moves to the left, and the connecting plate 11 is retracted into the inside of the support frame 2. The two ends of the support frame 2 and the connecting plate 11 are connected. The opening and closing of the outer guard plate 1 on the side is restricted to avoid deviation. The rotation of the circular sleeve 3 is adjusted until the protective cotton layers 9 on both sides are close to the injured part, so as to fix the injured part. When the internal cushion needs to be cleaned, the rotating handle 12 is rotated outward to disengage the mounting column 19 from the inside of the mounting frame 13, so that the inner steel plate 7 loses its fixing condition. At this time, the arc plate 6 is pulled upward by the slot on the outside, and the limit column 8 is disengaged from the hole inside the arc plate 6 to remove the inner steel plate 7 for cleaning.
