Purse-String and finger trap
The purse-string pattern is used at the end of a hollow organ stump or around a tube being placed in a hollow organ or a cavity. The pattern is made by taking partial thickness bites (Cushing suture pattern) in the tissues in a parallel fashion around the entire stump of tissue or opening. Next invert the tissues within the purse string suture, pull the suture ends to tighten and knot.
The finger-trap (Roman sandle suture) helps prevent accidental pull-out of the tube by tightening on the tube if it gets pulled out.
