摘要：
In one aspect, an instrument for placing a graft, implant and/or graft material at a target site for enhancing posterolateral fusion between two or more vertebrae is provided which includes a housing and an actuable trigger associated with the housing. A curved rigid access tube extends from the housing, the access tube terminating at a distal end. A sheath is disposed about, and moveable relative to the access tube, and a transmission is disposed in the housing. In an initial state, the sheath extends distally past the distal end of the access tube, a space being defined within the sheath distally of the distal end of the access tube to accommodate the graft, implant and/or graft material. The transmission is configured to cause an incremental displacement of the sheath relative to the distal end of the access tube upon an actuation of the trigger.
