OSTEOTOMY DEVICE AND OPERATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/184670
Kind Code:
A1
Abstract:
Disclosed is an osteotomy device, comprising an osteotomy plate (10), a fixing plate (20) and an adjusting structure (30), wherein the osteotomy plate (10) is mounted on a femur (B) via the fixing plate (20), two ends of the adjusting structure (30) are respectively connected to the fixing plate (20) and the osteotomy plate (10), and the osteotomy plate (10) slides left and right relative to the fixing plate (20) via the adjusting structure (30); and the osteotomy plate (10) has a femoral osteotomy groove (11) for performing an osteotomy from four sides and a femoral trochlear osteotomy groove (12) for performing femoral trochlear osteotomy. Using the osteotomy device, a femoral trochlear osteotomy operation can be carried out after performing an osteotomy operation from four sides without replacing the osteotomy plate (10), thus effectively reducing the number of instruments and avoiding repeated disassembly and assembly. In addition, using the adjusting structure (30), the osteotomy device can conveniently adjust the osteotomy plate (10) to slide left and right relative to the fixing plate (20), so as to adjust the osteotomy plate (10) to a position, directly facing the femoral trochlea, on the femoral trochlear osteotomy groove (12), thus improving the accuracy of femoral trochlear osteotomy.
