This invention provides a surgical retractor for colorectal cancer surgery, belonging to the technical field of surgical retractors. It includes a damping shaft with first connecting blocks fixedly installed at both ends. Through an adjustable structure, before using the retractor, pushing a push button moves it and a push rod from the protruding groove of the limiting groove to the straight groove. After the straight wound support piece is moved to the appropriate position on the wound, pushing the push button and push rod to the corresponding protruding groove causes a locking plate to engage with the first locking groove on the lower part of the connecting strip, thus fixing the position of the push rod and the straight wound support piece. This makes adjusting the retractor more convenient. One side of the straight wound support piece is flat, while the curved wound support piece can be directly pulled down and rotated on one side of the connecting sleeve block via a hinge block to make the curved wound support piece vertical. The side of the curved wound support piece that contacts the wound is curved, allowing for selection of a suitable curved surface based on the wound's condition.
