Description

Technical Field

[0001] The utility model relates to the technical field of osteotomy correction reduction, and more particularly to a chimeric latch tooth reduction guide plate used for osteotomy correction. Background Art

[0002] In orthopedic surgery, osteotomy and correction is one of the effective ways to treat skeletal abnormalities and malformation. However, conventional osteotomy is different from ordinary fracture reduction (with reduction reference). After the osteotomy operation is completed during the operation, the bone ends are often repeatedly reduced during the operation. After temporary fixation with Kirschner wires, the alignment of the bone ends is checked through X-ray fluoroscopy to evaluate the osteotomy effect and limb force line. However, the reduction process and effect are related to the experience of the surgeon. At the same time, repeated X-ray fluoroscopy during the operation not only increases the operation time, but also increases the patient's bleeding and radiation exposure. In addition, incomplete osteotomy and correction may occur after the operation, or even overcorrection, resulting in a series of corresponding complications.

[0003] Chinese Patent Authorization Publication No. CN210990575U provides a 3D-printed osteotomy guide. This solution adapts to the distal femur through a connecting portion, facilitating the attachment of the first and second guide plates to the femur, thereby improving the accuracy of the femoral guide. During osteotomy surgery, the first, second, and third planes provide a guide surface for the scalpel, allowing the scalpel to fully align with the guide surfaces of the first, second, and third planes. During osteotomy, only the bone needs to be cut along each plane, ensuring both accuracy and time. Osteotomy is performed in two directions relative to the distal femur, allowing the osteotomy guide to fit more precisely with the deformity, thereby improving osteotomy accuracy, facilitating the surgeon's operation, and facilitating the patient's early recovery. However, in its specific implementation, the following drawbacks exist: the osteotomy guide cannot be repositioned after osteotomy, requiring the surgeon to perform intraoperative alignment and fixation of the bone ends to complete the correction.

[0004] Therefore, in order to solve the above problems, a chimeric latch tooth reduction guide plate for osteotomy correction is proposed. Utility Model Content
