Insertion instrument

摘要

A method of deploying a fixation mechanism includes providing an insertion instrument and a fixation mechanism, creating an insertion tunnel within tissue of a patient, and positioning the insertion instrument with the fixation mechanism in the insertion tunnel. The insertion instrument includes a main member connected to an instrument handle and a secondary member connected to a pushing handle and positioned within the main member. The main member and the secondary member extend along a longitudinal axis. The fixation mechanism includes a first portion coupled to the main member and a second portion coupled to the secondary member. The method includes translating the pushing handle along the longitudinal axis relative to the instrument handle such that translating causes the secondary member to move the second portion relative to the first portion.
