1. A tissue manipulation device comprising:
a handle portion extending along a longitudinal axis from a proximal end to a distal end;
an adjustment member displaceably coupled to the proximal end of the handle portion;
a securing member coupled to the handle portion, the securing member extending along a member axis from a proximal end to a distal end, the securing member including an engagement portion disposed at or adjacent to the distal end of the securing member, wherein the proximal end of the securing member is coupled to a portion of the adjustment member such that the securing member is displaceable along the member axis between a first securing member position and a second securing member position, wherein the securing member is pivotably coupled to the handle portion and is pivotably displaceable between an engaged position and a disengaged position, and wherein in the engaged position, the member axis is parallel to or coaxially aligned with the longitudinal axis, and in the disengaged position, the member axis is not parallel to or coaxially aligned with the longitudinal axis;
a shaft portion extending from a proximal end to a distal end along a shaft axis, wherein the proximal end of the shaft portion is coupled to the distal end of the handle portion;
an end effector removably coupled to the distal end of the shaft portion, the end effector being operable between a first undeployed position and a second deployed position; and
a flexible wire extending from a proximal end to a distal end, wherein the distal end of the wire is coupled to the end effector, wherein the proximal end of the wire is removably coupled to the engagement portion of the securing member when the securing member is in the engaged position and the proximal end of the wire is disengaged from the engagement portion of the securing member when the securing member is in the disengaged position,
wherein when the securing member is in the engaged position, the wire couples the securing member and the end effector such that (a) when the securing member is displaced from the first securing member position to the second securing member position, the end effector is displaced from the first undeployed position to the second deployed position and (b) when the securing member is displaced from the second securing member position to the first securing member position, the end effector is displaced from the second deployed position to the first undeployed position.
