Description

Technical Field

[0001] This utility model relates to the field of orthopedic postoperative fixation technology, specifically an orthopedic postoperative leg elevation fixation frame to prevent displacement. Background Technology

[0002] In orthopedic clinical practice, especially after major surgeries such as lower limb fractures (e.g., femoral, tibia and fibula fractures), joint replacements (e.g., total knee / hip replacement), and ligament repair, it is crucial to follow the doctor's instructions to elevate the affected limb at the specified angle and maintain its stability.

[0003] Existing leg elevation fixation frames support the leg through an adjustable telescopic rod structure and a leg fixation clamp structure. The leg is raised and fixed in its postoperative position using the leg fixation clamp, thus preventing secondary injury caused by leg displacement. However, when the injured area is the lower leg, only the lower leg can be raised and fixed, while the thigh is left suspended in the air without a support point. This requires muscle assistance, and prolonged support can easily lead to muscle stiffness and even affect blood circulation, causing discomfort to the patient. Overall, the actual user experience is poor. Therefore, there is a need to improve the orthopedic postoperative anti-displacement leg elevation fixation frame to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a leg elevation fixation frame for preventing displacement after orthopedic surgery, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leg elevation fixation frame for preventing displacement after orthopedic surgery, comprising a bed and a mounting frame structure assembled on its side, a fixed shaft fixedly mounted on the front of the mounting frame structure, a rotating rod fixedly mounted on the outside of the fixed shaft, a control rod rotatably mounted inside the rotating rod, a threaded rod threaded inside the mounting frame structure, and a slider rotatably mounted on the outside of the threaded rod.

[0006] Preferably, the slider is slidably mounted inside the mounting frame structure, and the end of the control rod away from the rotating rod is rotatably mounted inside the slider.

[0007] Preferably, a rotating frame is rotatably mounted inside the rotating rod, and two outer cylinders are rotatably mounted outside the rotating frame. Each of the two outer cylinders has a protrusion fixedly mounted on its exterior. Four springs are fixedly mounted inside the rotating rod. A positioning plate is fixedly mounted at the end of each spring away from the rotating rod. Two connecting posts are fixedly mounted on the front of the positioning plate, and a movable sleeve is fixedly mounted at the end of each connecting post away from the positioning plate.

[0008] Preferably, the movable sleeve is slidably mounted on the outside of the rotating frame, and the connecting column and the positioning plate are both slidably mounted on the inside of the rotating rod.

[0009] Preferably, the rotating frame and the positioning plate are provided with insertion holes at corresponding positions, and the positioning plate is inserted into the insertion holes.

[0010] Preferably, the rotating frame has a power supply slot inside, and each of the two mounting shafts of the rotating frame has a heating wire inside. Both outer cylinders and the two mounting shafts have ventilation holes.

[0011] Preferably, the heating wire is connected to the power socket via a wire, and a leg clamp is fixedly installed on the back of the lifting plate of the mounting frame structure.

[0012] Compared with the prior art, this utility model provides a leg elevation fixation frame for preventing displacement after orthopedic surgery, which has the following beneficial effects: 1. This orthopedic postoperative anti-displacement leg elevation fixation frame uses a leg fixation clip that attaches a fixation strap to the outside of the hanging column to fix the patient's leg against displacement. Both outer cylinders are adjusted to abut against the lower side of the patient's thigh, thereby supporting the thigh and further supporting and elevating the injured leg to further prevent leg displacement.

[0013] 2. Based on this, the present invention uses an electric heating wire to generate heat, and then the heat is transferred to the outside through the ventilation hole to keep the patient's thigh warm, so that the patient's leg is warm and blood circulation is facilitated, avoiding the problem of numbness caused by poor blood circulation and poor user experience.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] Example 1: Please see Figure 1-4 This utility model provides a technical solution: a leg elevation fixation frame for preventing displacement after orthopedic surgery, including a bed body 1 and a mounting frame structure 2 assembled on its side. A fixed shaft 3 is fixedly installed on the front of the mounting frame structure 2. A rotating rod 4 is fixedly installed on the outside of the fixed shaft 3. A control rod 5 is rotatably installed inside the rotating rod 4. A threaded rod 6 is threaded inside the mounting frame structure 2. A slider 7 is rotatably installed on the outside of the threaded rod 6.

[0019] Furthermore, the slider 7 is slidably installed inside the mounting frame structure 2, and the end of the control rod 5 away from the rotating rod 4 is rotatably installed inside the slider 7, so that the rotation of the control rod 5 drives the rotating rod 4 to rotate around the fixed axis 3.

[0020] Furthermore, a rotating frame 8 is rotatably installed inside the rotating rod 4, and two outer cylinders 9 are rotatably installed outside the rotating frame 8. A protrusion 10 is fixedly installed on the outside of each of the two outer cylinders 9. Four springs 11 are fixedly installed inside the rotating rod 4. A positioning plate 12 is fixedly installed at the end of the spring 11 away from the rotating rod 4. Two connecting posts 13 are fixedly installed on the front of the positioning plate 12. A movable sleeve 14 is fixedly installed at the end of the two connecting posts 13 away from the positioning plate 12, which can drive the positioning plate 12 to disengage from the inside of the rotating frame 8.

[0021] Furthermore, the movable sleeve 14 is slidably mounted on the outside of the rotating frame 8, and the connecting column 13 and the positioning plate 12 are both slidably mounted inside the rotating rod 4, so that the rotating frame 8 can be adjusted at will.

[0022] Furthermore, the rotating frame 8 and the positioning plate 12 are provided with corresponding insertion holes, and the positioning plate 12 is inserted into the insertion hole to fix the position of the rotating frame 8.

[0023] Example 2: Please see Figure 4-5 Furthermore, in conjunction with Embodiment 1, it is further found that the inside of the rotating frame 8 is provided with a power slot 15, the inside of the two mounting shafts of the rotating frame 8 is provided with heating wires 16, and the two outer cylinders 9 and the two mounting shafts are provided with ventilation holes 17, so that the heat generated by the heating wires 16 is transferred to the legs for heating through the ventilation holes 17.

[0024] Furthermore, the heating wire 16 is installed with the power socket 15 via wires, and a leg clamp 18 is fixedly installed on the back of the lifting plate of the mounting frame structure 2 to prevent the patient's leg from shifting.

[0025] In actual operation, when this device is used, the mounting frame structure 2 is snapped onto one side of the bed 1 of the patient's injured leg. The mounting frame structure 2 is installed in the appropriate position on the bed 1 by tightening the screws. At this time, the leg fixation clamp 18 is located in the position required by the patient. The leg fixation clamp 18 is adjusted to the appropriate position by driving the lifting screw, and the lower leg is fixed by the leg fixation clamp 18, so that the injured leg cannot be moved at will, thus facilitating rest. Then, the threaded rod 6 is rotated and threaded inside the mounting frame structure 2, which drives the slider 7 to rise and fall, so that the control rod 5 rotates and drives the rotating rod 4 to rotate around the fixed shaft 3, so that the rotating frame 8 and the outer cylinder 9 are positioned relative to the patient. Pulling the movable sleeve 14 away from the rotating rod 4 on the lower side of the thigh compresses the spring 11, which is initially in a stretched state. At this time, the positioning insert 12 disengages from the rotating frame 8 and retracts into the rotating rod 4. The rotating frame 8 can then rotate around the central axis installed inside the rotating rod 4. Rotate the rotating frame 8 until both outer cylinders 9 are against the lower side of the patient's thigh. Then release the movable sleeve 14. At this time, the spring 11 rebounds and moves the positioning insert 12, so that the positioning insert 12 is inserted into the insertion hole of the rotating frame 8, thus fixing the position of the rotating frame 8. This allows the two outer cylinders 9 to support the patient's thigh, further supporting and elevating the injured leg and further preventing leg displacement.

[0026] Furthermore, in cold weather or when the patient is cold, the external power cord plug can be plugged into the power socket 15, causing the two heating wires 16 to heat up. The heat is then transferred to the outside through the ventilation hole 17 to keep the patient's thigh warm, which facilitates blood circulation and avoids the problem of numbness caused by poor blood circulation and poor user experience.

[0027] Furthermore, the power input terminal of the heating wire 16 is connected to the power socket 15 via a wire.

[0028] Furthermore, the leg fixation clip 18 secures the patient's leg against displacement by attaching a fixation strap to the outside of the hanging post.

[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
