An apparatus includes a grounding member and an actuator. The grounding member includes a first grounding feature and a bending channel. The first grounding feature is configured to engage a dilation instrument. The bending channel is configured to receive a malleable member of the dilation instrument. The actuator is pivotably coupled with the grounding member. The actuator has a bearing surface. The bearing surface is configured to cooperate with the bending channel to thereby bend the malleable member of the dilation instrument as the actuator is pivoted relative to the grounding member.
