Abstract
To provide a pressure relief device for controlling the outflow of fluid from a surgical site.SOLUTION: A pressure relief device 10 includes a cannula body 16 having a proximal end and a distal end 20 with a thread 24 extending along the entire cannula body from the distal end. The device also has a proximal end cap connected to the proximal end of the cannula body, a spacer connected between the cannula body and the proximal end cap, and a proximal seal enclosed between the proximal end cap and the spacer. One or more distal seals can be enclosed between the spacer and the proximal end of the cannula body. The device additionally includes a channel between the spacer and an inner wall of the proximal end cap. Fluid flows out of the device through the channel.SELECTED DRAWING: Figure 6
