A surgical device providing multiple functions including aspiration, irrigation, traction, filtration, dissection and compression of tissue, the surgical device comprising an elongate shaft having a proximal end and a distal end, a mobilization tip operatively attached at the distal end of the elongate shaft for manipulating tissue, and a valve assembly operatively connected to the proximal end of the elongate shaft for selectively delivering and removing an irrigation fluid to and from a surgical site through the elongate shaft. The surgical device is operable with one hand. The surgical device is dimensioned according to its use in either open or minimally invasive surgery. The mobilization tip comprises a traction-enhancing material formed of reticulated foam or from a woven or braided fabric. The mobilization tip further includes a porous filter for preventing biological matters from being inadvertently drawn into the aspiration holes or windows at the distal end of the elongate shaft.

Cette invention concerne un dispositif chirurgical offrant de multiples fonctions telles que l'aspiration, l'irrigation, la traction, la filtration, la dissection et la compression de tissus, lequel dispositif chirurgical comprend une tige allongée comprenant une extrémité proximale et une extrémité distale, une pointe de mobilisation fixée de manière opérationnelle à l'extrémité distale de la tige allongée et servant à manipuler les tissus, ainsi qu'un ensemble de valve relié de manière opérationnelle à l'extrémité proximale de la tige allongée et servant sélectivement à apporter un fluide d'irrigation sur le site chirurgical ou à l'évacuer de celui-ci par la tige allongée. Le dispositif chirurgical peut être manipulé d'une seule main. Ce dispositif chirurgical est dimensionné en fonction de son utilisation soit en chirurgie ouverte, soit en chirurgie avec effraction minimale. La pointe de mobilisation comprend un matériau renforçateur de traction composé de mousse réticulée ou de tissu tissé ou gainé. La pointe de mobilisation comprend en outre un filtre poreux servant à empêcher les matières biologiques d'être aspirées par inadvertance dans les orifices ou les fenêtres d'aspiration situés au niveau de l'extrémité distale de la tige allongée.
