Abstract
A medical device includes a link, a first tool member, a second tool member and a third tool member, which each have a proximal end portion movably coupled to the link and a distal end portion. The distal end portion of the first tool member can engage a first object and be associated with a first medical function, the distal end portion of the second tool member can engage a second object and be associated with a second medical function, and the distal end portion of the third tool member can engage the first object or the second object and be associated with the first and/or second medical function. Each of the first, second and third tool members can move relative to the link independent of movement of the each of the other tool members.
