Abstract[English]
An example surgical instrument includes an insulated shaft, and an expandable electrode at a distal end of the insulated shaft. The expandable electrode includes a shape memory alloy lattice. Based on passing electrical current through the shape memory alloy lattice, the shape memory-alloy lattice undergoes a shape memory-transition from a non- expanded configuration to an expanded configuration causing the expandable electrode to radially expand outward in diameter.[French]
Un exemple d'instrument chirurgical comprend une tige isolée, et une électrode extensible au niveau d'une extrémité distale de la tige isolée. L'électrode extensible comprend un réseau d'alliage à mémoire de forme. Sur la base du passage du courant électrique à travers le réseau d'alliage à mémoire de forme, le réseau en alliage à mémoire de forme subit une transition de mémoire de forme d'une configuration non déployée à une configuration déployée amenant l'électrode extensible à s'étendre radialement vers l'extérieur en diamètre.
