Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an adjustable orthopedic external fixation bracket. Background Art

[0002] Orthopedic external fixators are widely used to treat a variety of fractures and bone-related conditions, especially in complex fractures or when precise fixation of the bone is required to promote healing. These devices provide a support structure outside the body to properly align and stabilize the broken bones, thereby limiting unwanted movement and accelerating the recovery process. The use of external fixators reduces the need for surgical intervention, which is particularly important in patients who are not directly eligible for surgery or who have a higher risk of surgery.

[0003] Existing orthopedic external fixators are mostly made of metal rods, screws and clamps, which are fixed directly to the bone through external mechanical means to provide the necessary stability. These devices can be adjusted according to the patient's specific fracture situation to accommodate fractures of different sizes and complexities. In this way, the external fixator can effectively maintain the correct position of the bone, promote the natural healing process of the bone, and ensure that the fracture area is fully protected and stabilized during the recovery period.

[0004] Although existing external fixators play a key role in fracture treatment, there are still some shortcomings. First, these devices are often complicated in operation and adjustment, requiring frequent adjustments by professional medical personnel, which can easily lead to delays and inconveniences in the treatment process. Second, existing braces are insufficient in patient adaptability. After wearing them, users can easily put pressure on the recovery part when moving around in daily life, which can aggravate the condition and reduce the recovery speed. Finally, the traditional fixation braces are not designed with sufficient adjustability, making it difficult for them to adapt to changes in the patient's body or provide appropriate support at different stages of treatment. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an adjustable orthopedic external fixation bracket. The present invention increases the adjustability and patient adaptability of the device through the coordination of a clamping mechanism, an adjustment mechanism, a fixing mechanism and a supporting mechanism, which not only reduces the frequency of adjustments by medical personnel, but also improves the patient's wearing comfort and convenience in daily activities, thereby accelerating the recovery speed and reducing the patient's discomfort.

[0022] Working principle: When in use, firstly, steel needles are respectively inserted into the two bones that need to be connected to support the bones. Secondly, the pull rod is pulled to separate the protrusion and the groove, and the compression spring 2 is compressed while separating. At this time, the reel can be driven to rotate by rotating the pull rod, so that the distance between the two shells can be controlled, and it is adjusted according to the length of the repair area, and the two steel needles can enter the two shells. At this time, the connecting plate 1 and the connecting plate 2 are connected, and at the same time, the sleeve will enter the shell and squeeze the card block, so that the card block compresses the compression spring 1. When the card block moves to a position perpendicular to the card slot, the card block can be ejected into the card slot by the compression spring 1, thereby connecting the clamping mechanism and the steel needle. By adjusting the position of the clamping mechanism, the bones fixed by the steel needle can be connected and kept connected, thereby speeding up the recovery.

[0023] Among them, by rotating the two screw rods and making the clamping plate 1 and the clamping plate 2 approach each other under the limit of the limit rod, the device is fixed outside the user's body, and the fixing effect is improved under the action of the anti-slip pad, while reducing the impact on the user's body;

[0024] When used on the legs, the mounting plate is rotated to drive the I-shaped rod to twist and compress the spring, and at this time, the second splint can be connected to the turned-over mounting plate, thereby improving the stability of the connection plates 1 and 2 after they are connected, and preventing the restored part of the user from contacting the ground when walking, thereby improving the comfort of the user and avoiding affecting the user's life. The fixed plate drives the second support plate to move upward by driving the electric push rod, thereby adjusting the length of the support mechanism. When the device is used at different heights, the support mechanism can also provide a supporting effect, and after the second support plate is removed, the I-shaped rod is used to flip the mounting plate into the fixing mechanism under the action of the spring, thereby preventing the user from contacting the mounting plate during use, thereby improving the comfort of the device.

[0025] Finally, the pull rope is reeled in by rotating the rotating rod, and the card block can be pulled out from the middle of the card slot while reeling in, so as to quickly release the clamping of the steel needle and quickly separate the device from the steel needle to facilitate the subsequent removal of the steel needle.

[0026] The present invention provides an adjustable orthopedic external fixator, which has the following beneficial effects:

[0027] 1. The present invention adopts a highly adjustable clamping mechanism, which enables medical personnel to adjust the fixing position of the steel needle according to the patient's specific fracture situation, thereby improving the accuracy of treatment. At the same time, it improves the speed of connecting and separating the steel needle, improves the simplicity of the device, and can maintain the connection state of the bone, thereby improving the recovery effect and speed.

[0028] 2. The present invention not only optimizes the contact texture between the device and the patient's body and reduces discomfort during use through the fixing mechanism and the supporting mechanism, but also enhances the stability of the entire device, while effectively reducing the local burden, so that the patient experiences less pain during treatment and promotes rapid healing of fractures.

[0029] 3. The present invention uses a storage mechanism to facilitate disassembly of the support mechanism when the device is not in use, and can fold up the protruding mounting plate, which significantly improves the portability of the device and provides convenience for daily medical operations.

The adjacent sides of the splint 1 204 and the splint 205 are respectively fixedly connected with anti-skid pads 206 of the same shape, and the opposite sides of the splint 1 204 and the splint 205 are both fixedly connected with a limiting rod 207, and the other end of the limiting rod 207 is fixedly connected with a baffle 208. The two limiting rods 207 are respectively slidably connected to the middle parts of the connecting plate 1 201 and the connecting plate 2 202. The splint 1 204 and the splint 205 are brought closer to each other by rotating the screw rod 203, so that the device is fixed outside the user's body, and the anti-skid pad 206 can improve the user's comfort and prevent the clamping from causing harm to the user.
