A scaffold assembly includes an instrument pod and a plurality of actuable movers. The instrument pod may include one or more instruments operably coupled thereto. The instrument pod is inserted through a tissue tract into the body cavity. Each actuatable mover includes an insertion member extending therefrom therefrom for insertion within tissue. Each mover has one or more lines removably attachable to the instrument pod that are configured to move the instrument pod between different positions relative to each mover upon the actuation of one or more of the movers to move the instrument pod within the body cavity.
