Final answer:
Retractors are surgical instruments used to hold tissue to the side away from the wound during surgical procedures, providing a clear view and access for the surgeon.
Step-by-step explanation:
Retractors are used in surgical procedures with the primary function being to hold tissue to the side away from the wound. This allows surgeons to have a clear view and access to the underlying structures or organs. Retractors come in various shapes and sizes and can be either hand-held or self-retaining. For example, when performing an abdominal surgery, a retractor may be used to hold the abdominal wall muscles aside to allow the surgeon to work on the internal organs without obstruction.
