Background

The combined abdominal-perineal rectal cancer radical operation (Miles operation) is suitable for low-level rectal cancer and patients who cannot keep anus for achieving the purpose of radical treatment of tumors. Because many parts are involved in the operation, including sigmoid colon, rectum and mesentery thereof, anal canal and skin around the anal canal, subcutaneous tissue, all anal sphincters, cleaning lymph nodes in the inferior mesenteric artery region and the like, two patients need to be respectively positioned at the abdomen and the perineum to carry out the tissue organ excision.

When the Miles operation is performed on the perineal region, the skin around the anal canal needs to be incised by about 5 cm. At this time, the anal canal can be regarded as the inner circle of a concentric circle, and the skin incision part is the outer circle. Taking the upper quadrant region as an example, the physician can pull the tissue of the outer ring to the outside by the small S-shaped retractor, and pull the tissue of the inner ring to the opposite direction. The traction directions of the two parts are always kept opposite, so that certain tension exists in the tissues, and the tissues are separated after the gaps are fully exposed. However, the perineum operation space is limited, so that an assistant often stands on the outer side of the thigh of a patient to be matched with an operator for visual field exposure, and long-time stooping posture and visual line limitation easily cause insufficient operative field exposure, and the time and effect of an operation are affected.
