Abstract
(EN)
The present invention is an expandable sleeve (704) deployable in a surgical implant. The sleeve (704) has a head (720), a tubular shaft (722) defining an open interior, and a distal tip (724) with the shaft (722) having a length dimension. The shaft (722) is provided with a plurality of slots (271) that divide the shaft (722) into partitions, wherein each of the partitions has a length, and the length of the partitions are not all equal. For example, the slots (271) may have a curved portion that extends at an angle between 00 and 900 to the length dimension of the shaft (722). The slots (271) may also have a straight portion and a curved portion. Further, the invention in another embodiments includes an expander pin (702), and in yet another embodiment, includes an expander pin (702).

L'invention concerne un manchon extensible pouvant être déployé dans un implant chirurgical. Ce manchon comporte une tête, un arbre tubulaire définissant un espace intérieur ouvert, ainsi qu'une pointe distale, l'arbre présentant une dimension longitudinale. Cet arbre est pourvu d'une pluralité d'encoches le divisant en plusieurs segments, chaque segment présentant une longueur, la longueur des segments n'étant pas égale. Les encoches peuvent par exemple comporter une partie courbe qui s'étend selon un angle compris entre 0° et 90° par rapport à la longueur de l'arbre. Ces encoches peuvent également comporter une partie droite et une partie courbe. L'invention concerne également, dans un autre mode de réalisation, une broche d'extension.
