In traditional mandibular reconstruction surgery, the fixation shape of reconstruction plates is difficult to adjust, relying entirely on the clinical experience of the surgeon for shaping. This results in complex and time-consuming procedures. The reconstruction plates often lack secure fixation and precise conformity to the reconstruction site, necessitating significant time and effort during mandibular reconstruction surgery. This adjustable reconstruction plate can be precisely fixed in position and angle, overcoming the limitations of traditional uniaxial variable-angle plates in terms of conformity, and offering a stable and efficient solution.This promotes healing at the affected site and reduces infection risks. This design is the world’s first medical device system for mandibular reconstruction surgery, significantly simplifying the surgical process, reducing patient discomfort, and improving overall recovery outcomes. The design adheres to ergonomic principles, not only reflecting minimalist aesthetics but also achieving ideal safety and immediate effectiveness.
