When handling sutures at high magnifications settings working with an operating microscope, it is impractical to handle suture materials with only one instrument. It becomes imperative to utilize instruments in both hands (i.e.: Castroviejo-type needle holder and tissue forceps) that allow for needle and thread manipulation without obstructing the operator’s view.
By setting multiple sewing needles with different eye sizes in a circle facing in different directions and at different heights, the operator is challenged to handle the suturing needle simulating clinical situations that require similar maneuvers.
