Claim 11:
12. A surgical grasper comprising:
an inner shaft assembly including an inner shaft defining a lumen for passage of a surgical instrument and an engaging portion peripherally arranged with the inner shaft such that the engaging portion conforms to a contour of the inner shaft;
an outer shaft slidably disposed about the inner shaft, the outer shaft including opposing supporting fingers, each of the supporting fingers including apertures;
a grasper assembly operatively coupled to the opposing supporting fingers of the outer shaft, the grasper assembly including a first jaw and a second jaw, the first jaw including a first grasping portion and a first pair of extension members extending proximally from the first grasping portion such that the first pair of extension members selectively engages the inner shaft, the second jaw including a second grasping portion and a second pair of extension members extending proximally from the second grasping portion such that the second pair of extension members selectively engages the inner shaft, the first pair of extension members and the second pair of extension members including bores, wherein axial displacement of the inner shaft transitions the grasper assembly between an approximated configuration and a spaced apart configuration; and
pins extending through each of the bores of the first pair of extension members, each of the bores of the second pair of extension members, and each of the apertures of the supporting fingers thereby coupling the first pair of extension members, the second pair of extension members, and the supporting fingers.
