Description

Technical Field

[0001] The invention relates to the technical field of orthopedic treatment instruments, and in particular to a device for reversely flipping a loop steel plate. Background Art

[0002] Traditional treatment methods and limitations: When the tibiofibular syndesmosis is injured and the tibia and fibula are separated, timely and effective internal fixation must be performed clinically to facilitate the reasonable and effective repair of the ruptured tibiofibular ligament. The traditional treatment method is to use one or two screws for reduction and fixation. This method is a strong and rigid fixation, and the elastic activity of the tibiofibular joint is lost. Therefore, a second surgery is required to remove the fixation screws before the patient gets out of bed and walks with weight. If weight is loaded too early, there is a risk of screw breakage. Limitations include: Secondary surgery to remove the tension screws increases the patient's pain and medical costs. Restricting the micro-motion of the tibiofibular joint affects the physiological function and biomechanical properties of the joint, and is prone to joint stiffness. The screws are subjected to greater stress, increasing the risk of screw breakage. Excessive rigid fixation affects the blood supply and cartilage nutrition supply to the joint, increasing the possibility of joint fusion, etc.

[0003] Compared with rigid fixation, elastic fixation can restore better dorsiflexion and plantar flexion functions in patients. The looped plate technology is used to treat tibiofibular separation and can provide relatively stable fixation: it helps to restore the normal anatomical relationship and stability of the tibiofibular joint. It allows micro-motion, which conforms to the physiological characteristics of the tibiofibular joint and is conducive to early functional training and recovery. Reduce screw-related complications: compared with traditional screw fixation, it reduces the risk of screw breakage, loosening and other problems. However, it has relatively high technical requirements and relatively high costs: due to its special instruments and materials, the treatment cost is higher than traditional methods. There may be poor reduction and the risk of soft tissue irritation.

[0004] In addition to rigid fixation and elastic fixation with loop plate technology, the most commonly used fixation procedure is the locking loop plate, which has the advantages of relatively less trauma, less damage to surrounding tissues, and more reliable fixation strength compared with the elastic fixation with loop plate technology. However, the locking loop plate requires auxiliary incision on the opposite side, is expensive, and relies on highly specialized instrument assistance. For clinical departments that lack such professional instrument support, there are still insurmountable obstacles in the treatment of elastic fixation of the tibiofibular syndesmosis. In summary, the current fixation methods for tibiofibular separation are insufficient in terms of biomechanical adaptability, fixation stability, postoperative complications, and medical costs, and are difficult to meet the current clinical needs for treatment effects and patient rehabilitation quality. Summary of the invention

[0036] Among them, a head section reinforcement wire 12 is wound between the loop steel plate 3 and the head section reinforcement wire 12, one end of the head section reinforcement wire 12 passes through the left flat through hole 17, and wraps around the partition column 14 for half a circle and then passes through the left flat through hole 17 in the reverse direction. After passing through the right flat through hole 17, the head section reinforcement wire 12 wraps around the partition column 14 for half a circle again until it passes through the right flat through hole 17 in the reverse direction.

[0037] A rubber protective sleeve 4 is fixedly connected to the outer surface of the handle 1 by glue, and 5-9 grooves are evenly spaced on the outer surface of the rubber protective sleeve 4. An anti-drop handle 5 is fixed to the rear end surface of the handle 1, and the diameter of the anti-drop handle 5 is 1.3 times the diameter of the handle 1.

[0038] The front end of the strip opening 7 passes through the front end of the puncture rod 2, and the rear end of the strip opening 7 cuts off the middle area of ​​the length of the puncture rod 2. The inside of the ring 8 is provided with a hole for the tail section reinforcement wire 9 to pass through and wrap around, and the top end of the connecting column 10 is flush with the upper end surface of the strip opening 7.
