The application discloses a pelvic tumor resection surgical incision construction system and a pelvic tumor whole piece resection system. When a tumor does not affect a Ⅳ area, a projection point of a iliac crest on a body surface is taken as a starting point, and a projection point on the body surface is extended in a pubis direction of the iliac bone. According to different extension points, a single smooth virtual incision path one is constructed by bending downward in a thigh direction. When the tumor affects the Ⅳ area and other areas, the virtual incision path is two independent and non-intersecting first incision paths and second incision paths. The first incision path is extended from a body surface projection point of a longitudinal axis of a vertebral body to a sacrum direction, and is an incision path that is inclined to a tumor side in a sacrum area. The second incision path is a line connecting a body back projection point of the iliac crest to a body front projection point, and is combined with a corresponding smooth virtual incision path one to construct a complete smooth virtual incision path two. Through the above-mentioned method, incision intersection can be effectively avoided, and the incision path is beneficial to blood supply, and the healing effect is ensured.
