Classification: CPC A | IPC A

Claim 16:
17. A medical device, comprising:
opposing first and second end effectors coupled together and configured to move from an open configuration to a closed configuration;
a first link, wherein the first end effector is pivotally connected to a distal end of the first link at a first position on a proximal end of the first end effector, the first link including a first slot at a proximal end of the first link configured to receive a first actuator pin slidable within the first slot between a first end and a second end of the first slot;
a second link, wherein the second end effector is pivotally connected to a distal end of the second link at a first position on a proximal end of the second end effector, the second link including a second slot at a proximal end of the second link configured to receive a second actuator pin slidable within the second slot between a first end and a second end of the second slot, and wherein each of the first slot of the first link and the second slot of the second link is a curved slot including two concave ends facing each other that are connected by a first concave sidewall and a second convex sidewall opposite the first concave sidewall; and
a clevis including a central longitudinal axis and a pair of distally extending and spaced apart arms, wherein a pivot pin is attached to each of the pair of arms, wherein each of the first and second end effectors is pivotally connected to the pivot pin at a second position of each of the first and second end effectors that is different than each of the first positions on the respective first and second end effectors;
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.
