Autonomous Tumor Prosthesis Lengthening System

The prosthesis system performs self-measurement of limb length using integrated sensors and automatically determines extension requirements without physician intervention. The system autonomously monitors its own state and initiates extension procedures based on detected length discrepancies, eliminating the need for periodic clinical visits and reducing both patient inconvenience and physician workload.

The patent replaces manual measurement methods (physical examination, radiographic imaging) with electronic sensing systems. Sensors continuously monitor limb length and transmit data to a control unit that automatically processes information and triggers extension when needed, substituting mechanical/clinical procedures with an automated electronic system.

The system replaces radiographic measurement with electronic sensing. Sensors integrated into the prosthesis directly measure limb length through electronic means, eliminating the need for repeated X-ray exposures while maintaining measurement capability through continuous electronic monitoring.

Instead of periodic radiographic measurements, the system implements continuous electronic monitoring of limb length. Sensors continuously track length changes and provide real-time data to the control unit, enabling ongoing measurement without interruption and without radiation exposure.

The system applies extension in small, controlled increments rather than large single steps. The control unit monitors length changes continuously and initiates multiple small extension cycles until the target length is reached, avoiding the discomfort associated with large sudden extensions while achieving the same overall length adjustment.

The extension process is divided into multiple periodic small-step extensions. The system performs repeated extension cycles with brief intervals between them, allowing gradual adaptation and maintaining patient comfort while achieving cumulative length adjustment over time.
