Classification: CPC A | IPC A

Claim 12:
13. A medical device, comprising:
opposing first and second end effectors coupled together and configured to move from a fully open configuration to a closed configuration, wherein the first end effector includes a first plurality of teeth, the second end effector includes a second plurality of teeth opposing the first plurality of teeth, and the first plurality of teeth contact the second plurality of teeth when the first and second effectors are in the closed configuration;
a first link pivotally connected to the first end effector at a first position on the first end effector and having a tapered width along a length of the first link, the first link including a first slot at a proximal end of the first link;
a first actuator pin slidable within the first slot;
a second link pivotally connected to the second end effector at a first position on the second end effector and having a tapered width along a length of the second link the second link including a second slot at a proximal end of the second link;
a second actuator pin slidable within the second slot; and
a clevis including a central longitudinal axis, the clevis including a body and a pair of arms extending distally from the body and defining a slot between the pair of arms, each of the pair of arms including a hole, wherein a pivot pin is fixedly attached to the hole at a second position in each of the pair of arms that is different from the first position, the clevis further including a pair of sidewalls at a proximal end of the slot where the slot meets the body, wherein the sidewalls are transverse to the central longitudinal axis of the clevis and restrict the first and the second end effectors from opening past the fully open configuration;
wherein, when the first actuator pin is stationary and the first and the second end effectors remain in the closed configuration, the first slot is movable over the first actuator pin and the first and second end effectors are configured to pivot about an axis of the pivot pin, causing a distal tip of one of the first and second end effectors to cross the central longitudinal axis of the clevis.
