Final answer:
The Edna Towel Clamp is a medical tool used in surgeries to secure sterile drapes over a patient, maintaining the sterile field without perforating the drapes.
Step-by-step explanation:
The Edna Towel Clamp, also known as a non-perforating towel clip, is a medical instrument used in surgical settings. It is designed to secure items to the drapes that cover a patient during surgery.
The main purpose of these clamps is to hold the sterile drapes in place, preventing them from shifting or falling during the procedure, which could compromise the sterile field. The Edna Towel Clamp does this by clamping onto the drapes without perforating them, retaining the integrity of the sterile barrier.
