摘要：
An instrument comprises a shaft assembly. The shaft assembly comprises a first shaft member including a distal cutting feature, and a second shaft member. The first shaft member is slidable relative to the second shaft member. At least a distal portion of the shaft assembly is sized to fit through a nostril. The instrument further comprises a body. At least a portion of the shaft assembly extends distally relative to the body. The body comprises a grounding feature sized and positioned to engage one or more external anatomical structures adjacent to the nostril. The instrument further comprises a dampener. The dampener resists advancement of the first shaft member relative to the second shaft member.
