Description

Technical Field

[0001] The invention belongs to the technical field of leg fractures, and in particular relates to a plaster auxiliary clamping device for leg fractures. Background Art

[0002] Plastering is an external fixation treatment method widely used in the medical field. It is mainly used for fixation and rehabilitation after fractures, joint injuries and certain orthopedic surgeries. It provides a stable mechanical environment for the injured part and promotes tissue repair and healing. The commonly used plaster material is mainly gypsum powder, which is made from raw gypsum after calcination and dehydration. When gypsum powder is mixed with water, a chemical reaction will occur, gradually hardening and setting. In actual operation, the gypsum powder will be evenly applied to a special gauze bandage (i.e., plaster bandage) and will play a fixing role after hardening. By fixing the injured limb in a specific position and restricting its movement, the fracture ends or injured parts are prevented from shifting, creating a stable environment for the repair of bones and soft tissues. For example, when the leg is fractured, plastering can prevent the fractured part from being dislocated due to the random movement of the leg, which helps the fracture heal. Fixing the injured part can reduce the stimulation of the injured part due to limb movement, thereby relieving pain. For example, after a joint sprain, plastering can give the injured joint a rest and relieve pain symptoms. A stable fixation environment is conducive to the formation and growth of callus at the fracture site, accelerating the fracture healing process; for soft tissue injuries, it can also reduce secondary damage to the injured area and promote tissue repair.

[0003] When a patient's leg fracture requires a cast, due to the bent leg, there is a gap between the leg and the plaster, which affects the normal healing of the fracture. Summary of the invention

[0012] Furthermore, the limiting bolt is also arranged in the corresponding positioning hole above or below the track bar.

[0013] Furthermore, the fastening bolts are arranged in the positioning holes on the edge of the reverse side of the fixing frame, and the fixing frame and the supporting structure around the leg are connected and fixed by the fastening bolts.

[0014] Furthermore, the track bar includes an integrally formed fitting portion and a sliding track portion, the fitting surface of the fitting portion fits with the edge of the front face of the fixed frame and is fixed by the fastening bolts, and the side face of the fitting portion is vertically connected to the sliding track portion; the limiting sliding block includes an integrally formed clamping portion and a bearing portion, the clamping portion is buckled on the sliding track portion, and the clamping portion can slide on the sliding track portion, the bearing portion is arranged at the upper end of the clamping portion, and the filling block fixing frame is inserted into the bearing portion.

[0017] Furthermore, the reinforcing rod is a structure of the same specification as the fixing frame, and the reinforcing rod and the fixing frame are fixed by welding.

[0018] Compared with the prior art, the beneficial effects of the plaster auxiliary clamping device for leg fracture provided by the present invention are:

[0019] Stable support: By installing multiple sets of fixed frames on the support structure around the leg, and the fixed frames are tightly supported by the support blocks and connected with fastening bolts, a stable basic support system is constructed. This can effectively disperse the external force on the leg, prevent the fracture site from shaking or displacement and affect healing, and provide reliable support for the entire fixation and treatment process.

[0020] Flexible adjustment of the position of the filling block: The design of the track bar and the limit slider allows the filling block fixing frame to slide freely on the track. In this way, the position of the filling block can be flexibly adjusted according to the gaps of different positions and sizes between the leg and the fixing plate, ensuring that the filling block accurately fills the gap and makes the plaster fit tightly to the leg, thereby effectively solving the gap problem caused by leg bending and promoting normal healing of fractures.

[0021] Adapt to the shape of the leg: The bending angle of the track bar fitting part is adapted to the bending angle of the leg, ensuring that the track bar can be installed closely to the contour of the leg. This not only enhances the stability of the entire device, but also enables the fixing plate to better fit the leg, further improving the fixing effect and reducing discomfort or fixing deviation caused by the device not fitting the leg.

[0022] Enhanced structural strength and stability: The fixed frame and reinforcing rod are welded to form a stable structure, which improves the strength and deformation resistance of the entire device. During the patient's daily activities or movements, it can withstand a certain amount of external force and is not prone to damage or deformation, ensuring the continuity and effectiveness of fixation and treatment.

[0023] Flexible limit and convenient movement: The roller, sleeve rod, compression spring and other components in the limit mechanism cooperate so that the moving seat can adjust the limit state by pressing the pressing plate during the movement. When it is necessary to move, press the pressing plate, the compression spring is compressed, the roller and the track are separated from the limit, and the moving seat is easy to move; after moving to the specified position, release the pressing plate, the compression spring rebounds, and the roller re-contacts the track to achieve limit, ensuring the stability of the moving seat.

[0024] Reliable fixing function: The fixing mechanism is driven by the meshing of bevel gears. The rotating disk drives the first bevel gear to rotate, and then the two second bevel gears rotate synchronously. The threaded screw rotates accordingly. The first L-shaped fixing block moves along the long strip opening under the action of the threaded screw, thereby realizing reliable fixation of the fixed frame and preventing it from displacement on the moving seat.

[0025] Enhanced stability: The second L-shaped fixed block, the connecting rod and the tension spring in the stabilizing mechanism cooperate with each other. When the mobile seat carries the fixed frame, the tension spring provides tension to make the second L-shaped fixed block in close contact with the fixed frame, thereby enhancing the stability of the entire device and preventing the fixed frame from shaking.

[0026] It can solve the problem that when a patient's leg fracture needs to be cast, due to the bending of the leg, there is a gap between the leg and the plaster, which affects the normal healing of the fracture. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Furthermore, in the above technical solution, the bending angle formed by the fitting surface and the side surface of the fitting portion 021 is matched with the bending angle of the leg to ensure that the track bar 02 is arranged to fit the leg.

[0048] Furthermore, in the above technical solution, the upper end and the lower end of the fixed frame 01 are respectively vertically connected with reinforcing rods 08, and the fixed frame 01 and the reinforcing rods 08 form a stable structure.

[0049] Furthermore, in the above technical solution, the reinforcing rod 08 is a structure of the same specification as the fixing frame 01, and the reinforcing rod 08 and the fixing frame 01 are fixed by welding.

[0050] Specifically, the principle of the present invention is: place the support structure in a suitable position and adjust it to a stable state so that it can effectively support the leg and provide a reference for the subsequent installation of components. Place multiple groups of fixed frames 01 in parallel and at intervals on the support structure around the leg, so that the upper and lower ends of the fixed frames 01 are accurately supported on the support block 06. Install the fastening bolts 09 in the positioning holes 10 on the front edge of the fixed frame 01, place the track bar 02 vertically, so that the fitting surface of the fitting part 021 is closely fitted to the front edge of the fixed frame 01, and then tighten the bolts to firmly fix the track bar 02 on the fixed frame 01. When installing multiple limiting sliders 03, adjust the spacing between them according to actual needs. Accurately insert the lower end of the filling block fixing frame 04 on the bearing part 032 of the limiting slider 03 to ensure that the connection is firm and will not fall off easily. Let the patient maintain a comfortable fixed posture, and according to the leg contour, start from one side of the leg, connect the fixing plate to the limiting slider 03 through the filling block fixing frame 04. Use a bandage or a fixing belt to initially fix the fixing plate. Pay attention to moderate strength during the fixing process. Observe the blood circulation of the patient's legs at any time to avoid over-tightening and affecting blood circulation. In the same way, place and fix the fixing plates on the other three sides of the leg in turn so that the leg is surrounded by the fixing plates. According to the size and shape of the gap between the leg and the fixing plate, select a suitable filling block to ensure that its material is soft and elastic, such as sponge, foam, etc., and will not cause skin allergies in the patient. Put the filling block into the filling block fixing frame 04, and adjust the position of the filling block by sliding the limit slider 03 so that it fits the leg and the fixing plate tightly and accurately fills the gap. Avoid causing additional pressure or movement on the fracture site during the operation. Press the pressing plate 16 hard, and the compression spring 15 is compressed at this time, and the sleeve rod 12 drives the roller 13 to shrink into the long strip groove, and the roller 13 is out of contact with the track, and the moving seat can move freely on the track. Push the moving seat to the desired position. After moving to the specified position, release the pressing plate 16, the compression spring 15 rebounds, and the roller 13 contacts the track again to limit the position. Then rotate the rotating disk 18, which drives the first bevel gear 19 to rotate. Through the meshing of the first bevel gear 19 and the second bevel gear 20, the threaded screw 21 rotates, and the first L-shaped fixed block 22 moves toward the fixed frame 01 under the action of the threaded screw 21 until the fixed frame 01 is firmly fixed on the moving seat. After the fixed frame 01 is placed on the moving seat, the stabilizing mechanism will automatically work. The tension spring 25 is in a stretched state, and a pulling force is applied to the second L-shaped fixed block 23 by connecting the pull rod 24, so that the second L-shaped fixed block 23 is tightly against the fixed frame 01, thereby enhancing the stability of the fixed frame 01 on the moving seat. If further adjustment of the stability is required, the degree of stretching of the tension spring 25 can be fine-tuned according to actual conditions.

[0051] The present invention comprises the following steps:

[0052] S10, preparing the supporting structure and fixing frame around the legs;

[0053] S20, installing the track bar and the limit slider;

[0054] S30, fixing the fixing plate and the filling block fixing frame;

[0055] S40, check the gap and insert the filling block;

[0056] S50, preparing gypsum;

[0057] S60, wrapping plaster bandage;

[0058] S70, trimming and fixing.

[0059] The specific implementation of the above steps is described in detail below.

[0060] The specific implementation method of step S10 is: according to the actual condition of the patient's legs, prepare a support structure around the legs, such as a customized leg fixing bracket, to ensure that it is stable and reliable and can effectively support subsequent devices.

[0061] Install multiple sets of fixed frames in parallel and at intervals on the supporting structure around the legs. The length of the fixed frames should match the spacing of the support blocks on the supporting structure, so that the upper and lower ends of the fixed frames are respectively supported on the support blocks. Then, use fastening bolts to pass through the positioning holes on the reverse edge of the fixed frames to firmly connect the fixed frames to the supporting structure.

[0062] It should be noted that when choosing a leg fixation brace, you should fully consider factors such as the patient's age, weight, fracture location and degree, and ensure that the strength and stability of the brace meet the requirements. Before installing the fixed frame, carefully check the position and stability of the support block to avoid tilting or shaking of the fixed frame during installation. When tightening the bolts, use appropriate tools and tighten them according to the specified torque to prevent the bolts from being too loose, causing the fixed frame to loosen, or from being too tight, damaging the fixed frame and supporting structure.

[0063] The specific implementation method of step S20 is: install fastening bolts in the positioning holes on the front edge of the fixed frame, and fix the track bar vertically on the fixed frame. The track bar is integrally formed by a fitting part and a sliding track part. The fitting surface of the fitting part is fitted and fixed to the front edge of the fixed frame. The bending angle formed by the fitting surface and the side surface needs to be compatible with the bending angle of the leg.

[0064] A plurality of limit sliders are installed on the sliding track portion of the track bar. The limit sliders are integrally formed by a clamping portion and a bearing portion. The clamping portion is buckled on the sliding track portion and can slide freely thereon.

[0065] It should be noted that before installing the track bar, it is necessary to confirm the compatibility of the bending angle of the fitting part and the bending angle of the leg again, which can be checked by simulated installation. When installing the fastening bolts, ensure that the track bar is perpendicular to the fixed frame to avoid tilting and affecting the sliding of the limit slider. When installing the limit slider, ensure that the locking part and the sliding track part are tightly buckled and can slide smoothly. A sliding test can be performed after installation. If there is any jamming, make timely adjustments.

[0066] The specific implementation of step S30 is: let the patient lie down or sit in a comfortable posture, and stretch the legs or keep them in a fixed posture specified by the doctor.

[0067] Insert the filling block fixing frame onto the bearing part of the limit slider, and then place the fixing plate starting from one side of the leg according to the leg contour. The fixing plate is connected to the limit slider through the filling block fixing frame. Use a bandage or a fixing belt to preliminarily fix the fixing plate. Pay attention to using moderate force to avoid affecting blood circulation. Place and fix the fixing plates on the other three sides of the leg in turn to surround the leg.

[0068] It should be noted that when the patient adjusts his posture, the action should be gentle to avoid secondary injury to the fracture site. Before placing the fixation plate, make sure that the filling block fixing frame is firmly connected to the limit slider to prevent it from falling off during the fixation process. When using a bandage or fixation belt to fix the fixation plate, always ask the patient how they feel and observe the skin color and blood circulation of the legs. If symptoms such as purple skin and numbness occur, the fixation strength should be adjusted in time.

[0069] The specific implementation of step S40 is: after the fixing plate is fixed, carefully check the gap between the legs and the fixing plate, and determine the area with a larger gap by observation and touch.

[0070] According to the size and shape of the gap, choose a suitable filling block and place it in the filling block holder. The filling block can be made of soft and elastic sponge, foam, etc. Make sure the filling block fits tightly between the leg and the fixation plate to fill the gap. During operation, be careful to avoid causing additional pressure or movement to the fracture site, and do not affect the subsequent plastering operation.

[0071] It is important to note that when checking the gap, you must be comprehensive and careful to avoid missing anything. When selecting a filler block, you must not only consider its size and shape to match the gap, but also ensure that its material is safe and hygienic and will not cause adverse reactions such as skin allergies. When inserting the filler block, the action should be slow and gentle to avoid excessive force that may cause impact on the fracture site. At the same time, ensure that the filler block is firmly installed and will not shift during subsequent operations.

[0072] The specific implementation of step S50 is: mixing gypsum powder and water in a clean container according to the specified ratio. Generally, a proper amount of water is poured into the container, and then the gypsum powder is slowly added, and the mixture is quickly stirred with a stirring tool until a uniform gypsum paste without lumps is formed.

[0073] It should be noted that the gypsum powder and water should be mixed strictly according to the ratio specified in the product manual. Improper ratio may affect the setting time and hardness of the gypsum. Stir quickly and evenly to ensure that the gypsum powder is fully dissolved to avoid lumps that affect the use of the gypsum. The prepared gypsum should be used as soon as possible to avoid solidification due to long-term storage.

[0074] The specific implementation method of step S60 is: quickly and evenly apply the prepared plaster paste on the plaster bandage.

[0075] Starting from one end of the leg, wrap the plaster-coated bandage tightly around the outside of the fixing plate and the filling block. During the wrapping process, pay attention to the uniform tension of the bandage to avoid looseness or excessive tightness.

[0076] After one layer of bandage is wrapped, you can continue to apply plaster paste and wrap multiple layers of bandages as needed to enhance the fixation effect of the plaster. Constantly adjust the position and angle of the bandage while wrapping to ensure that the plaster evenly covers the entire fixation plate and filling block and fits the shape of the leg.

[0077] It should be noted that plaster paste should be applied evenly to avoid uneven thickness. When wrapping the bandage, a certain tension should be maintained, but it should not be too tight to avoid affecting blood circulation. The tension and fit of the bandage can be checked every few turns. When wrapping multiple layers of bandage, pay attention to the connection between the layers to avoid stratification or gaps.

[0078] The specific implementation of step S70 is:

[0079] After wrapping the plaster bandage, use scissors to trim the excess bandage to make the edges neat.

[0080] Allow the plaster to harden gradually, avoiding movement of the leg during this time to ensure that the shape and position of the plaster are accurate.

[0081] After the plaster has completely hardened, check the fixing effect again, including the hardness of the plaster, whether the position of the fixing plate and the filling block is appropriate, etc. If necessary, make appropriate adjustments.

[0082] It should be noted that when trimming the bandage, be careful to avoid scratching the patient's skin with scissors.
