Which of the following is a non-penetrating towel clip used to secure cords or drapes?

The Edna clip is a key tool used in surgical settings specifically for securing drapes and cords without penetrating the underlying tissue. This non-penetrating towel clip is designed to securely hold materials in place during procedures, ensuring a sterile field while allowing ease of access for the surgical team. Its mechanism allows for a firm grip on the materials without causing trauma to the tissue, which is essential for maintaining patient safety and comfort during surgery.

In contrast, the other options listed serve different functions or are designed for different purposes. The Mixter is a type of clamp that is generally used for grasping or occluding blood vessels, while a hemostat is primarily utilized for controlling bleeding during surgical procedures by clamping tissue or blood vessels. The sponge stick, on the other hand, is used for handling sponges or suction devices during surgery but does not serve the specific function of securing drapes or cords like the Edna clip.
