A true innovation, the unique design of CONMED’s ARC Adjustable Retractor Cannula helps surgeons see more clearly, operate with greater range of motion and minimize cannula pull-out. The proprietary locking nut and distal wing design of this cannula retracts the deltoid fascia to create a large space for better visualization.This muscle retraction feature also creates more room in the subacromial space – making it easier to use and manipulate elongated instruments like suture passers.
