Patent

CA 2251711

The present invention provides a surgical grasper device (10) that comprises a generally elongate housing member (12) having a handle member (14) at a proximal end, and first and second grasping arms (20, 22) at a distal end. First and second grasping elements (24, 26) are preferably releasably attached to the first and second grasping arms (20, 22) respectively. The grasping elements (24, 26) are positioned on the arms (20, 22) in an opposed facing relationship to enable grasping a targeted surface, such as living tissue between the elements. A gripping material (36) at least partially covers or is otherwise incorporated into the surface of one or both of the grasping elements. The gripping material (36) provides enhanced holding power to the targeted surface relative to the holding power provided by the grasping elements in the absence of the gripping material (36).

L'invention concerne un dispositif chirurgical à préhension (10) qui comporte un élément d'enveloppe (12) généralement allongé présentant un élément manche (14) au niveau de son extrémité proximale et des premier et second bras de préhension (20, 22) au niveau de son extrémité distale. Les premier et second éléments de préhension (24, 26) sont de préférence fixés amovibles respectivement aux premier et second bras de préhension (20, 22). Les éléments de préhension (24, 26) sont placés sur les bras (20, 22) face à face de sorte qu'il soit possible de saisir une surface cible tel que des tissus vivants entre les éléments. Un matériau de préhension (36) recouvre au moins partiellement la surface d'au moins un des éléments de préhension ou est autrement intégré à au moins l'un d'eux. Le matériau de préhension (36) augmente la puissance de retenue à la surface ciblée par rapport à la puissance de retenue fournie par les éléments de préhension en l'absence du matériau de préhension (36).
