Abstract
An irrigation system including a pump that regulates the supply of fluid to an endoscopic surgical site, and a tubing set for supplying the fluid. The tubing set comprises an inflow line for supplying fluid to the surgical site, and an outflow line for draining fluid from the surgical site. At least one of the inflow and outflow lines includes an expandable compliant tubing segment that expands to accommodate changes in the rate of fluid flow through the surgical site to reduce variations in fluid pressure in the surgical site. The fluid volume within the compliant tubing segment increases in response to increasing fluid pressure within the compliant tubing segment. The system is particularly designed for use in small joint arthroscopy (e.g., of the wrist) where the fluid volume in the surgical site is relatively small.
