How much does the pressure change when the shaver is turned on?
Standard suction tubing will cause the joint to collapse and visualization to cease when the shaver is used. This problem is caused by a negative pressure level in the joint. Standard inflow with gravity provides 1,200cc of fluid per minute into the joint, which will provide sufficient distention for the joint. The problem occurs when the shaver is used. Suction canisters provide outflow rates around 2,000 cc of fluid per minute. Since the rate of flow out of the joint is greater than the rate of flow entering the joint, the joint collapses and visualization is compromised. StableVac solves this problem by reducing the amount of fluid leaving the joint via the suction canister. Rather than 2,000cc per minute, StableVac reduces this outflow rate to 800cc per minute. This creates a system with 1,200cc of fluid per minute into the joint, 800cc of fluid per minute out of the joint, and 400cc of fluid inside the joint to provide superior distention, pressure and visualization.
