Abstract
An insertion system includes a handle assembly and a nose assembly removably attached to the handle assembly and including an insertion end. The handle assembly includes a main body, a nose interface and an actuating element. The nose assembly includes a nose, a positioning rod extending from the nose to a distal end, a cutting sheath surrounding a distal end of the positioning rod and including a cutting edge, an actuation member having a proximal end coupled to the actuating element when the nose assembly is attached to the handle assembly and a distal end attached to the cutting sheath, a ventilation tube positioned distal to the distal end of the positioning rod and proximal to the insertion end. The cutting sheath retracts from around the ventilation tube and along the positioning rod when the actuating element on the handle assembly is moved.
