1. A biopsy forceps device, comprising:
an end effector including a first jaw opposing a second jaw, wherein the first jaw and the second jaw are coupled together and configured to move from an open configuration to a closed configuration,
wherein the first jaw includes a first edge and the second jaw includes a second edge, and wherein at least a portion of the first edge contacts at least a portion of the second edge in the closed configuration of the end effector,
wherein the first jaw includes a first plurality of teeth each having a base and a peak, wherein and the second jaw includes a second plurality of teeth each having a base and a peak, and
wherein, in the closed configuration of the end effector:
a gap is formed between (a) a portion of the first edge that extends between the base of a proximalmost tooth of the first plurality of teeth and the base of a second-most proximal tooth of the first plurality of teeth, and (b) a portion of the second edge that extends along the peak of a proximalmost tooth of the second plurality of teeth,
a first window is defined between the first edge of the first jaw and the second edge of the second jaw, wherein the first window is proximal to the proximalmost tooth of the first plurality of teeth and the proximalmost tooth of the second plurality of teeth, wherein the first window has a first maximum height,
a second window is defined between the first edge of the first jaw and the second edge of the second jaw, wherein the second window is distal to (a) the first window and (b) the proximalmost tooth of the first plurality of teeth and the proximalmost tooth of second plurality of teeth, wherein the second window has a second maximum height, and
a third window is defined between the first edge of the first jaw and the second edge of the second jaw, wherein the third window is distal to the first window and the second window, wherein the third window has a third maximum height,
wherein the first maximum height is greater than the second maximum height, and wherein the third maximum height is greater than the second maximum height.
