The Super-V Cannula®
Minimally invasive, maximally productive
Minimally invasive surgery may have revolutionized the field of orthopedic surgery, but that doesn’t mean it can’t be improved. The efficacy and safety of minimally invasive surgery depends on the quality and quantity of access surgeons have to their operative field.
The Super-V Cannula is designed specifically to maximize both of these parameters. The Super-V Cannula is smaller, less traumatic, and more effective than its competitors, making it one of the most minimally versatile arthroscopic tools on the market.
Super-V Cannula Devices
Super-V Cannula SVC-85
The original super V cannula utilizes 2 Nitinol strips which are pre-contoured to provide arthroscopic retraction during primarily hip arthroscopy and shoulder arthroscopy.
- Allows passage of the arthroscope through the cannula.
- The retraction provided by the Nitinol Allows usage in all but the largest patience.
- Additional retraction provided by included C clamp
Inside Diameter: 8 mm
Working Length: 85 mm
Retracted Length: 50 mm
- C clamp-included
- Removable fluid gate-included
- Disposable obturator-included
Short webbed Super-V Cannula SVC-W70
This second generation webbed Super-V Cannula is more ideally suited for rotator cuff surgery and smaller patients.
Inside Diameter: 8.5 mm
Working Length: 70 mm
Retracted Length: 35 mm
- Requires reusable obturator (not included)
Can be delivered directly off of 5.8 to 6.0 mm arthroscopy sheath (Stryker, Arthrex, Smith&Nephew) – Requires nose ring for direct delivery.
Webbed Super-V Cannula SVC-W85
This is a webbed version of the original Super-V Cannula. Webbing provides additional soft tissue retraction at the point of entry into the joint or space.
Inside Diameter: 8.5 mm
Working Length: 85 mm
Retracted Length: 50 mm
- Requires reusable obturator (not included)
Can be delivered directly off of 5.8 to 6.0 mm arthroscopy sheath (Stryker, Arthrex, Smith&Nephew) – Requires nose ring for direct delivery.
The Placeholder PH-85
This is a modular arthroscopic retracting cannula. The 3 Nitinol strips are sold separately, reusable, and loaded externally.
The inner cannula is removable from the base to allow passage of ACL graphs, dermal graphs for superior capsular reconstruction procedures, etc.
Inner Diameter of Cannula: 9.0 mm
Inner Diameter of Placeholder Base with Cannula Removed: 12 mm
- Requires reusable obturator (not included)
Uses the Nitinol strips that are embedded in the original super V cannula-85 mm with independently adjustable retraction on each of the three fins.
Super-V Cannula Accessories
Nitinol Strips
These are the hyperelastic skeleton of the Arthroscopic Innovations line of cannulas.
Length: 8.5 mm
- They are sold separately in 12 packs for use in the Placeholder cannulas.
- Shape set for adjustable 3-finned retraction in the placeholders cannula
Nose Ring (patent pending)
The Arthroscopic Innovations line of cannulas are the only cannulas on the market that provide true arthroscopic retraction using proprietary Nitinol technology.
They are also the only cannulas that can be loaded and deployed directly off of the standard 5.8-6.0 mm metal arthroscopy sheaths already used during surgery.
Diameter: 8.5 mm
- Will not damage existing arthroscopy sheath
- Can be used with existing (4mm) switching sticks.
Reusable Obturator
All of the Arthroscopic Innovations cannulas can be loaded onto the reusable obturator
Cannulation: 2.4 mm
Unique Features of the Super-V Cannula
Reduced Tissue Trauma
The Super-V Cannula’s design minimizes the risk of normal tissue injury during cannula insertion to the greatest degree on the market. We have eliminated obstructive threads that reduce visibility and the need to twist the cannula upon insertion. Further, we’ve achieved a reduction in the cross sectional area of tool-on-tissue contact by 50%. These advances mitigate tissue injury while providing timely access to the surgical field.
Improved Surgical Visualizations
The Super-V Cannula’s auto-retracting nitinol fins retract soft tissue and improve surgical visualization. Surgeons can expect an improved surgical working area with a wider working angle.
Versatility
The Super-V Cannula maintains portal and improves view regardless of patient size, so it can effectively treat a diverse group of patients. Also, it can be used for both intra-articular and subacromial procedures.
Innovative Use of Nitinol
The Super-V Cannula is the only arthroscopic device that uses nitinol to overcome limitations caused by the minimally invasive approach. The unique auto-retracting nitinol fins provide excellent, but flexible arthroscopic retraction.
More Effective Fluid Retention
The Super-V Cannula has multiple levels of fluid management. Its auto-retracting fins minimize backflow from the fluid gate and limit liquid leakage.
Effortless Insertion and Removal
The auto-retracting fins remain closed until the instrument is fully inserted. Removal is simple and atraumatic.
Reloadable and Reusable
The Super-V Cannula can be reloaded and reused over and over again, making it a cost-effective and environmentally friendly tool for minimally invasive surgical procedures.
Shortens Operative Time
By improving visualizations and expediting the insertion process, the Super-V Cannula helps surgeons save precious time in the operating room.
Sizing Down the Competition in Minimally Invasive Surgery
Size matters in minimally invasive surgery. The smaller the cannula, the lower the risk for normal tissue injury, and the more likely the patient is to make a speedy and complete recovery.
The Super-V Cannula compresses for a minimal profile during insertion. This makes it one of the smallest minimally invasive surgical instruments on the market.
Most of the cannulas surgeons use that have an inside diameter of 8mm have an outside diameter of 11-12 mm (not including the threads that push on it!). In comparison, the outer diameter of the Super-V Cannula is only 8.01 mm. The SVC’s outer diameter is smaller than its competitors because of the compressive nature of nitinol and elastomer that line the cannula walls. The inner diameter of the SVC is still closer to 8 mm, which allows for the passage of even the largest arthroscopic instruments.
