Conventional three-portal knee surgeries utilize a dedicated fluid cannula inserted above the patella into the joint space via a third portal incision. This technique offers continuous fluid inflow/outflow and optimal visual clarity.
The use of metal cannulae demands special care to prevent articular cartilage injury, including repositioning of the device whenever the knee is articulated during surgery to prevent clogging. Metal cannulae are considered the primary source of “third portal” pain.
The patented ClearVu cannula, constructed of flexible plastic, flexes to follow the inner contours of the knee. Its unique “progressive” flexibility provides rigidity at the proximal end for control, and a safer, softer fenestrated distal tip that never clogs or scores.

Made of a soft polymer, the patented TwoVu sheath slips easily over the arthroscope’s own sheath to create a second channel to establish continuous flow of irrigation fluid, providing optimal visual clarity and improved efficiency during percutaneous shoulder and hip and two-portal knee arthroscopies. This eliminates having to switch from inflow to outflow on the scope to regain image clarity and remove debris. Providing continuous fluid flow also reduces the potential for damaging fluid flow build-up in the joint when using RF ablation devices.
With knee arthroscopy, TwoVu eliminates the need for a third portal … as well as the post-operative pain typically associated with it. TwoVu is available in sizes to fit nearly all scopes commonly used for knee, shoulder and hip arthroscopy.

In addition to providing all the functions of a conventional instrument cannula, the EntreVu EX (short for “Extravastat”) cannula also actively drains extravasating interstitial fluid, minimizing the amount of interstitial swelling during shoulder and hip arthroscopy.
The escape of pressurized irrigation fluid into the interstitial tissues of the shoulder or hip is the cause of extravasation. If left uncontrolled, extravasation can interfere with the surgery and influence the choice of technique and equipment, sometimes forcing the surgeon to switch to an open procedure. Fluid extravasation during shoulder and hip arthroscopy must be monitored closely.
EntreVu’s ability to efficiently and continuously drain extravasating fluids is thanks to the patented Extravastat technology incorporated into the cannula. EntreVu is also a superior portal and provides other excellent fluid management capabilities.

Optimized for the special needs of shoulder and hip arthroscopy, the TwoVu EX (short for “Extravastat”) provides both a continuous fluid irrigation channel and an anti-extravasation channel for draining interstitial fluids. Made of a soft polymer, this versatile scope sheath is especially practical whenever a percutaneous approach is utilized and is frequently used with one or more EntreVu EX instrument cannulas to provide maximum anti-extravasation capabilities.

In addition to preventing fluid loss from abandoned portals, ExtravaStopper is the first portal plug to also control fluid extravasation, even in problem areas like the anterior portal. Its innovative Extravastat technology enables it to reduce fluid extravasation by continuously draining interstitial fluids, visibly reducing swelling of soft tissues.
Simply load this easy-to-use device onto a 4mm blunt switching stick to quickly insert it into a portal, then connect it to ordinary suction (e.g., to a bucket or Stryker Neptune or similar collection receptacle).
What’s more, ExtravaStopper keeps fluid in the joint and off the OR floor, meaning less mess and fuss and quicker cleanup.

Escaping irrigation fluids that enter the camera/scope junction will quickly fog the lens, forcing the surgeon to halt the procedure to clean the equipment. The patented DryVu “fluid shield” diverts fluids away from the camera. Designed to fit all brands and models of arthroscopes, this device is both efficient and inexpensive.

The reusable cannulated obturator was designed specially for use with the EntreVu EX instrument cannula to provide an easy-to-use “driver” system for it. Made of durable stainless steel, its ergonomic handle provides superior grip and control. The obturator is compatible with most common 4mm (nominal diameter) and smaller Wissinger rods and switching sticks.

The Squid 3-into-1 fluid collector lets you quickly connect multiple suction devices with from within the sterile field to reduce suction lines over the patient. Also eliminates need to constantly disconnect and switch RF, shaver or Extravastat devices. Easy pinch-clamp control. Perfect for central waste collection systems.
