Perineal surgery retractor kits designed for use during procedures involving the rectum and associated tissues and/or anatomic structures. These kits typically consist of a collection of devices, instruments, and supplies that are combined to temporarily separate and retain the perineal wall and/or the rectum edges, exposing and/or giving access to the rectum, without manual support once they are set (i.e., self-retained). The retractors frequently consist of a flexible small round ring, a set of blades of different sizes usually providing lateral retraction, a ratchet mechanism to adjust retractor tension, and a fixation post that is usually attached to an operating table whose end is dropped; the kits may incorporate fiber optic systems to illuminate the surgical site. Rectum peritoneal retractor kits provide hands-free assistance to the surgeon during the procedure; dedicated rectum retractor kits with other physical configurations are also available.
