1. An actuation device comprising:
a device body that comprises a first fixation mechanism configured to affix a proximal end of a first member of an accessory device to the device body and a portion configured to be coupled to a working channel of a medical device, wherein the portion defines a lumen; and
an actuator comprising an operable mechanism, a second fixation mechanism configured to affix a proximal end of a second member of the accessory device to the actuator, wherein the second member extends through an interior of the first member, wherein movement of the operable mechanism from a first position to a second position is configured to move the second member distally relative to the first member, and movement of the operable mechanism from the second position to the first position is configured to move the second member proximally relative to the first member,
wherein the operable mechanism pivots about a point offset from a longitudinal axis of the first member and the second member,
wherein the second fixation mechanism is configured to move from a first end of a curved path to a second end of the curved path, and wherein a distance from the first end to the second end defines a maximum distance the second member is configured to move relative to the first member, and
wherein, in a configuration in which the portion of the device body is coupled to the working channel of the medical device:
a first portion of the first member and a first portion of the second member extend through the lumen of the portion,
a second portion of the first member and a second portion of the second member are both external to the device body and the actuator, wherein the second portions of the first and the second members are proximal of the respective first portions of the first and the second member, and
a third portion of the first member and a third portion of the second member extend into the working channel of the medical device, wherein the third portions of the first and the second members are distal to the respective first portions of the first and the second member.
