ClearVu 2.7
Flexible Inflow-Outflow Cannula for Three-Portal Knee Arthroscopy
Featuring a number of significant user-requested upgrades for 2019, ClearVu™ 2.7 is the first and only cannula engineered to bend with an articulating joint, allowing it to maintain continuous fluid flow and clarity while significantly reducing the potential for soft tissue and articular surface damage. New features include:
1. Attractive new design with flat ergonomically designed grip area on the valve body for positive control when inserting the cannul.
2. Proximal ribs to keep the ClearVu from backing out during manipulation of the knee during surgery.
3. Longer luer connector to accommodate a wider range of tube set fittings such as luer connectors and funnel connectors.
4. Positive valve stop for accurate fluid flow control. Turn right (counterclockwise) to open the flow valve and left (clockwise) to close it.
A significant advancement over traditional rigid metal cannulae, ClearVu's tapered design and polymer construction provide "progressive" flexibility. Combined with its other unique design features, they allow it to:
- Easily conform to contours of the joint no matter how it is articulated during knee arthroscopy, ensuring maximum fluid flow and clarity.
- Deliver uninterrupted flow and debris evacuation in a much smaller OD (and, therefore, much smaller incision) for consistent visibility.
- Avoid the kind of skiving, scuffing, and denting that can occur with a metal cannula (especially as it is repositioned).
- Remain in place throughout the
procedure, since you won't have
to reposition it to restore sufficient fluid flow. - Allow for more fenestrations at the distal tip so flow is not blocked and evacuation and visibility remain constant, even when the knee is in a figure-four position.
- Not ‘short out’ radio frequency ablation or thermal remodeling devices, even upon direct contact.
"Metal canulas are not flexible. They can cause joint damage during manipulation and clog with synovium. ClearVu creates a smaller hole than a metal cannula. The skin quality of older patients has a higher risk of permanent damage from trauma and wound healing problems. ClearVu solves this. Its flexibility reduces tissue trauma to the knee during manipulation. ClearVu also remains patent in the figure 4 position, and I can control outflow more accurately."
