Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a hallux valgus osteotomy guide plate for orthopedic surgery, to solve the existing similar inconvenient to extend and shorten the transverse guide knife slot, and unable to adapt to the first metatarsal of different lengths for transverse guide. Knife, and it is not easy to retract and store, and it is inconvenient to fix. It is easy to change the position during hallux valgus osteotomy, resulting in uneven surgical section, and it is impossible to make the left and right "Z" oblique transverse guide distances according to different first metatarsals. According to the operation plan, the "Z" type oblique guide distance from the center of the horizontal macro adjustment, and the "Z" oblique guide length operation plan at the left and right ends that cannot be made for different first metatarsals, and the "Z" type The problem of adjusting the length of the oblique guide

Abstract

The invention provides a hallux valgus osteotomy guide plate for orthopedic surgery, which relates to the technical field of medical devices and includes a right guide plate; a transverse knife guide groove is provided on the right guide plate, and the outer end structure of the left guide plate is the same as that of the right guide plate; A sliding frame is slidably installed in the installation frame; an adjustment block is slidably installed in the sliding frame; the invention is convenient for extending and shortening the transverse knife guide groove, and can adapt to the first metatarsal of different lengths to carry out the transverse knife guide, And it is convenient for retractable storage and storage. The device avoids the problem of uneven surgical cross-section caused by position changes during hallux valgus osteotomy, and the device can be guided according to the left and right ends of the first metatarsal. The surgical plan of the distance, and the lateral macro adjustment of the distance from the center of the "Z" oblique guide, and the surgical plan of the left and right "Z" oblique guide length of the different first metatarsal bones, and the "Z" type Adjustment of the diagonal guide length.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more particularly relates to a hallux valgus osteotomy guide plate for orthopedic surgery. Background technique [0002] Hallux valgus is one of the common deformities of the foot. Specifically, it means that the big toe deviates outward from the midline, and the angle of inclination is greater than 15 degrees. It is often accompanied by complex deformity of the first metatarsal varus and the axial rotation of the big toe. The word Scarf is an architectural term, its English meaning is inlaid, similar to the mortise and tenon structure often used in woodworking; 1926: Meyer first reported the first metatarsal longitudinal axis "Z"-shaped osteotomy; 1976: Burutaran Reported 4 cases of Keller procedure plus 1st metatarsal "Z" osteotomy for hallux valgus; 1984: Gudas and Zygmund started using 1st metatarsal lateral "Z" osteotomy and reported his treatment results ; 1990: Barouk modified...
