US Patent 7785287 Arthroscopic fluid control device

The fluid control device is attached to tubes carrying irrigation solution to form the system. The control device splits the flow through a fiber optic scope and a fluid control unit. The fluid control unit controls rate of flow and direction. The flow of fluid into the joint, out of the joint, or no flow is easily controlled by the operator. The device also allows more than one inflow, useful when using suction or suction shaving devices. The increased flow prevents collapse of a joint space and maintains clear visualization. The fluid flow relies on gravity by having a fluid reservoir positioned at a high point in the system.
