The invention discloses a colorectal tumor operation tumor-free device and a using method. The tumor-free device comprises a first supporting part, a second supporting part and a lock catch structure.The first supporting part comprises a semicircular first supporting ring. The second supporting part comprises a semicircular second supporting ring. The lock catch device comprises a male buckle andfemale buckles which correspond to each other and can be embedded into each other. The male buckle and the female buckle are respectively arranged at the two ends of the first supporting ring and thesecond supporting ring in pairs. A thin film is arranged to connect the first supporting ring and the second supporting ring, and the two sides of the thin film are respectively fixed to the first supporting ring and the second supporting ring which are oppositely arranged. According to the invention, the problem of abdominal implantation of tumor cells caused by accidental dispersion of tumors in an operation can be solved.
Description
technical field [0001] The invention belongs to the field of laparoscopic surgical instruments, and in particular relates to a tumor-free device for colorectal tumor surgery and a use method thereof. Background technique [0002] Tumor-free technology: It was first proposed by medical scientist Cole et al. in 1954. It refers to a series of measures taken to reduce or prevent the shedding, planting and dissemination of tumor cells during malignant tumor operations, including no extrusion, tumor isolation, and tumor-free flushing. The first purpose is to prevent the tumor from spreading along the blood and lymphatic channels; the second is to prevent tumor cell wounds from growing. It is the basic principle that surgical medical personnel must abide by during the operation. [0003] Principles of tumor-free technology: [0004] 1. The principle of non-squeezing in tumor surgery: malignant tumor surgery emphasizes that the movements should be as gentle as possible, and the t...
