摘要
Distraction Osteogenesis (DO) revolutionizes bone lengthening without donor sites, which is crucial in maxillofacial reconstruction (MRA). Manual DO devices are standard, but continuous DO devices promise faster treatments and better outcomes. Current continuous distractors lack ideal MRA due to size, force generation, and power source limitations. This study introduces a passive distractor system for continuous DO in MRA, aiming to bridge existing gaps and provide an ideal solution for human MRA use. It utilizes a miniaturized mechanism powered by a passive energy source, eliminating the need for active power. Advanced manufacturing methods enable the reduction of device size while hydraulic systems ensure controlled and smooth movement. The system includes a proximal bone fixture, movable distractor components, and passive drive means for distraction force application. Results show promising potential to address existing limitations. By utilizing passive energy for continuous force generation, the device size is reduced, and the need for force transition mechanisms is minimized. This innovative system and method offer an ideal treatment environment for MRA in humans. Further research and clinical evaluation are essential to validate its efficacy and safety in clinical practice.
