Self-retaining retractors are surgical instruments used in surgical procedures to hold organs and tissues back so that the surgeon has an unobstructed view of the surgical area and can perform the operation with greater precision. These retractors have locking mechanisms that keep the blades apart and in place while spreading the edges of the incision and holding other tissue in place. Self-retaining retractors can be set to retract themselves without the need for constant attention or intervention by the surgical team. These retractors can have different shapes and sizes depending on the specific surgical procedure for which they are used. Self-retaining retractors are made of high-quality, lightweight, stainless steel materials . They are an indispensable tool in many surgical procedures, including abdominal, vascular and plastic surgery.
