Abstract
Methods and devices are provided utilizing an end effector having three jaws movably coupled thereto for grasping and/or dissecting tissue. In one embodiment, each of the three jaws are movable between an open position in which the distal ends of the three jaws are spaced apart from one another, and a closed position in which the distal ends directly contact one another. The jaws can define an opening therebetween when the jaws are in the closed position.

A surgical device, comprising:
- an end effector having first, second, and third non-cutting, atraumatic jaws movably coupled thereto, each jaw having a proximal end and a distal end, each jaw having a distal tip portion in the form of a substantially triangular prism having a first sidewall and a second adjacent sidewall, and each jaw being movable between an open position in which the distal ends of the three jaws are spaced apart from one another, and a closed position in which the first sidewall of each jaw is in direct contact with the second sidewall of an adjacent jaw.
A surgical device, comprising:
- an end effector having first, second, and third longitudinally extending jaws coupled thereto at a proximal end thereof and movable between open and closed positions, the first, second, and third jaws having non-cutting, atraumatic distal tips that directly contact one another in the closed position, each distal tip having first and second tissue contacting surfaces, and each tissue contacting surface having a plurality of surface features formed thereon and spaced along a longitudinal length thereof, and the first, second, and third jaws defining an opening therebetween in the closed position.
