1. A medical device, comprising:
a handle that includes a pair of pins positioned on opposing surfaces at a proximal end of the handle and extending radially inward relative to a longitudinal axis of the handle;
a shaft extending distally from the handle;
an end effector extending distally from the shaft;
a first actuator coupled to the handle and secured to a first wire, wherein the first actuator includes:
a housing that includes a first channel and a distal opening, wherein the first channel is configured to receive a proximal portion of the first wire extending distally from the housing and through the distal opening, and
a distal extension that includes a pair of sidewalls, and a pair of pin openings formed in opposing surfaces of the pair of sidewalls; and
a second actuator coupled to the handle and secured to a second wire, wherein the second actuator is received within a slot of the handle, wherein the second wire extends through the shaft and is coupled to the end effector,
wherein the pair of pins of the handle and the pair of pin openings of the first actuator define a pivot point, such that the first actuator is pivotably coupled to the handle about the pivot point;
wherein the first actuator is configured to deflect the end effector to a deflected configuration relative to the shaft in response to pivoting a proximal portion of the first channel towards a proximal direction about the pivot point, and the first actuator is configured to return the end effector to an undeflected configuration relative to the shaft in response to pivoting the proximal portion of the first channel towards a distal direction about the pivot point,
wherein the second actuator is configured to translate relative to the slot of the handle to pull the second wire proximally to actuate the end effector.
