Patent ID: 8613752

Claim:
A surgical instrument comprising: a tubular member having a proximal end, a distal end, and at least one lumen extending between the proximal end and the distal end; a grasper extending within a lumen of the tubular member, the grasper comprising first and second grasping members each having a distal body, each distal body having an inner surface with an opening formed therein, the inner surfaces of the first and second grasping members facing one another, the grasping members pivotally coupled to one another at a first pivot point to move about the first pivot point between an open configuration and a closed configuration; a cutting device extending within a lumen of the tubular member, the cutting device having first and second cutting members each with at least one cutting edge configured to sever a body vessel or tissue, the first and second cutting members being pivotally coupled to one another at a second pivot point to move about the second pivot point between a free configuration and an engaged configuration; and a rod coupled to the tubular member and extending transversely across a lumen of the tubular member, wherein the first and second grasping members are pivotally coupled to the rod at the first pivot point, the first and second cutting members are pivotally coupled to the rod at the second pivot point, and the first and second grasping members and the first and second cutting members are configured to pivot about an axis of the rod; and wherein the grasping members are movable between the open and closed configurations independent of movement of the cutting members between the free and engaged configurations.
