Abstract: This retractor easily ensures a surgical field as desired by an operator, can flexibly ensure and change the surgical field in accordance with the surgical site and the surgical situation, and can easily be moved to a desired position in the surgical site and taken out after the surgery. A retractor 1 holds a surgical incision in a body in an opened state to ensure a surgical field in small-incision endoscopic surgery, and includes a base body 2 that is a thin plate made of tin having a purity of not less than 99.9% and has an elongated rectangular shape in an extended state of the base body. The retractor 1, in an extended form in a rectangular shape or in a rounded form in a small shape, can be inserted from a small incision wound into the body, and can easily be delivered to the surgical incision in the body by a surgical instrument. The base body 2 is bent and deformed into a desired shape by the surgical instrument and is applied to the surgical incision in the body, so that the surgical incision can be held in an opened state so as to ensure the surgical field. The base body 2 is made of tin having a purity of not less than 99.9%, and thus the base body 2 has a high flexibility in particular, thereby allowing the base body 2 to be easily bent and deformed into a desired form by use of the surgical instrument.

Abstract: Provided is a retractor that makes it possible to reduce operation costs, is less likely to cause damage to surgical incision sites, do not reduce workability, and also makes it possible to easily maintain the desired surgical field and to change the surgical field or widen or narrow the area of the surgical field, depending on the surgical situation. The retractor 1 for holding a surgical incision open and maintaining a surgical field during an operation includes a belt-shaped body A made of a wire; and a connecting part B that is provided at one end portion of the belt-shaped body A and capable of being connected to another end portion or an intermediate portion of the belt-shaped body A so that the belt-shaped body A can be formed into a loop of a desired size. The retractor 1 is so configured that when the belt-shaped body A is formed into a loop, the outer surface of the belt-shaped body A resists the force generated at the surgical incision and acting in such a direction as to close the surgical incision.
