These reusable circular stapler head sizers more closely resemble the form of circular staplers and are superior to conventional sizers for stapler selection. Like the stapler with its anvil detached and center rod retracted, each sizer has a curved shaft and a head with a flat forward profile.
These light weight sizers will not trap air ahead of themselves when they are passed to the apex of a closed rectal or rectosigmoid stump due to the presence of a venting channel through the head.
If a CIRCULAR STAPLER HEAD SIZER can be inserted to a preferred stapling location, then a stapler of similar size can reliably be positioned.
They are also useful for removing feces from the rectum prior to stapler insertion, when bowel preps are poor or not performed.
