Patent

CA 2422231

A generally U-shaped surgical staple comprises a base 10 and a pair of generally "L"-shaped legs 12 extending substantially perpendicularly from opposite ends of the base respectively. The legs 12 in use of the staple are bent through approximately 9~ relative to the base. To effect a greater compression of the stapled tissue the legs include a penetrative portion 16 adjacent the tip and a compressive structure 30 which, due to its increased height relative to that of the penetrative portion, spreads the compressive forces of the staple further along the length of the incision being closed. The compressive portion also provides a depth stop to avoid the tip penetrating too deeply into the tissue in which it is deployed.

L'invention concerne une agrafe chirurgicale en forme générale de U comprenant une base (10) et une paire de branches en forme générale de "L" (12) s'étendant sensiblement de manière perpendiculaire à partir d'extrémités opposées de la base, respectivement. Les branches (12), au cours de l'utilisation de l'agrafe, sont pliées à approximativement 90· par rapport à la base. Les branches comprennent, en vue de conférer une compression plus importante du tissu agrafé, une partie de pénétration (16) adjacente à la pointe et une structure compressive (30), diffusant, en raison de son hauteur accrue par rapport à la partie de pénétration, les forces compressives de l'agrafe le long de la longueur de l'incision étant fermée. La partie compressive met en place une butée de profondeur de manière à empêcher la pointe de pénétrer trop profondément dans le tissu dans lequel elle est déployée.
