Smart Vision - Model RF - Arthroscopy Double Pump

SmartVision is a patented technology owned by Insightra, which automatically adjusts the pressure and flow when blood or debris is detected. The SmartVision function consists of an optical detector located behind the Patient Cassette. Through deviation of LED light the detector can differentiate between blood and debris and adjust fluid pressure and flow rate accordingly. When the sensor detects blood, both the pressure and flow is increased in steps. When the bleeding stops and the blood is flushed out of the joint, the pressure and flow gradually decreases to its original setting. If the sensor detects debris, the flow is increased, until the surgeon again has a clear field of vision.

The Double Pump RF has the ability to communicate with a RF generator, allowing optimal pressure and flow settings during ablation in the joint. The Double Pump RF controls both the in- and out-flow and consequently both pressure and flow. The pump operates through usage of disposable slide-in tubing cassettes, one cassette which controls the in-flow (Day Cassette, used for one surgical day) and one that controls the out-flow (Patient Cassette, new for every patient). The key advantages of using the Double Pump are:

The fluid used is saline which is administrated through two types of cassettes, a “Patient” and a “Day” cassette. The Day cassette is used for one surgical day and transports the fluid from the sterile saline bag via the pump to the joint, where it connects to the arthroscope sheath.

The Patient cassette then transports the contaminated fluids from the joint, through an outflow cannula, via the pump and into a waste dispenser. However, today some surgeons exclude the usage of separate outflow channel (via the disposable cannula). Instead evacuation of irrigated fluids is made through the working port or through the Shaver (if the function “Shaver suction” is available on the pump).

Neither of these alternatives to the disposable outflow cannula is efficient when it comes to visibility, which is most often compromised due to bad fluid management performance when a proper evacuation port is excluded. The evacuation issue is one of most important areas of improvement to reach a problematic-free arthroscopic procedure with maximum visibility.
