1. A method of engaging tissue, the method comprising steps of:
providing a forceps comprising:
a housing defining an internal passageway and a longitudinal axis extending between proximal and distal ends of the housing,
a first jaw slidably and pivotably connected to a distal portion of the housing via a connecting pin, wherein the first jaw comprises a first opening including a first portion and a second portion, and wherein the first portion and the second portion of the first opening have different shapes,
a second jaw slidably and pivotably connected to the distal portion of the housing via the connecting pin, wherein the second jaw comprises a second opening including a first portion and a second portion, and wherein the first portion and the second portion of the second opening have different shapes,
a first connection member having a first end pivotably attached to the first jaw,
a second connection member having a first end pivotably attached to the second jaw,
and a driver pivotably connected to a second end of the first connection member and a second end of the second connection member;
advancing the forceps in a closed configuration through a body lumen until the forceps are near a target tissue site;
moving the driver in a distal direction relative to the housing to move the first and second jaws to an open configuration;
positioning the first and second jaws adjacent to the target tissue site; and
securing a tissue sample within the first and second jaws by moving the driver in a proximal direction relative to the housing to rotate the first and second jaws with respect to the connecting pin when the connecting pin is disposed within the first portions of the first and second openings and relative to the housing from the open configuration towards the closed configuration, wherein movement of the driver in the proximal direction also moves the first and second jaws longitudinally with respect to the connecting pin along the second portions of the first and second openings in the proximal direction along the longitudinal axis of the housing, and wherein when the connecting pin is at least partially disposed within the second portions of the first and second openings, the first and second jaws are prevented from fully rotating between the open configuration and the closed configuration.
