The competitive sheaths feature different options for the Stryker, Dyonics and Storz style scopes. The sheaths are rotatable double stopcocks and the obturators and trocars are sold separately. The sheaths are 6 mm outer diameter, which will be an advantage during pump trials due to the higher flow rate.
The continuous flow sheath is offered only in a Storz style fitting. The dual lumen sheath features rotatable stopcocks, one for inflow and one for outflow. This has an outer diameter of 6.5 mm, but with sufficient flow that will typically be used in two portal knee cases with the DualWave pump. The outer sheath has a J-Lock connection for cleaning purposes, and this sheath only has a blunt obturator option. (https://www.arthrex.com)
