The device illustrated is a simple cloth triangle with a hem on the two long sides to permit the introduction of the blades of a curved dressing forceps.

This tape is to be fastened to one of the finger-rings of the handle, so that the triangle will not slip from the blades. The purpose of the instrument is readily understood from the drawing.
When an abdominal wound is ready to be closed, the instrument (forceps blades adjusted into triangle) is inserted, the points of the blades carried within the peritoneal cavity and brought against the under surface of the parietal peritoneum. The blades are now separated as widely as possible. This puts the cloth diaphragm on the stretch, and while retaining the viscera, permits
