AI Technical Summary

Technical Problem

Traditional osteotomy plates cannot adapt to the diverse needs of patients' bone morphology and deformities, resulting in a wide variety of surgical instruments, cumbersome operations, high costs and insufficient osteotomy accuracy.

Method used

An adjustable osteotomy plate was designed. Through the multi-dimensional adjustment structure of the fixed block and the osteotomy guide block, including up and down movement, front and back flipping, and left and right flipping, combined with the limiting design of bolts, nuts and pins, precise matching and dynamic adjustment of different bone morphologies can be achieved.

Benefits of technology

It simplifies surgical operations, reduces medical costs, improves osteotomy accuracy and stability, adapts to the personalized needs of different patients, and supports real-time adjustments to improve surgical results.
