Abstract
Abstract An anchor sheet and anchor body for holding a cannula within the abdominal cavity of a patient is described. The cannula is used during a laparoscopic surgical procedure. The anchor sheet and anchor body assist in holding the cannula in a preferred orientation relative to the abdominal cavity. An attachment mechanism such as a hook and loop fastener may be utilized to connect the anchor sheet to the anchor body.
