Technical Field
The utility model belongs to the technical field of the medical treatment, concretely relates to through anus colon rectum tractive device that turns up.
Background
The NOSES operation is a novel minimally invasive operation which takes out surgical specimens through natural cavities (rectum, vagina and oral cavity) of a human body and only leaves a plurality of small holes during laparoscopic surgery. Compared with the traditional laparoscopic surgery, the NOSES surgery has the advantages that an auxiliary specimen taking incision is avoided, and the trauma is smaller; the patient is lighter, and the use of analgesic drugs is obviously reduced; the abdominal wall functions better; better beauty effect, faster recovery of patients, better psychological state and the like. For example, the sample is taken out through the anus by pulling the sample out from the pre-cut part of the far-end rectum through the anus, for example, the middle and lower segment tumor of the rectum can be pulled out through the rectum in an outward turning mode, or the rectum mesentery can be dissociated to the basin under the laparoscope according to the total rectum mesentery excision principle, the rectum is cut off at the lower edge of the tumor by 2-3cm, the near-end intestinal canal is pulled out through the anus, the tumor is cut off under the external direct vision, and the anastomosis is carried out in vitro.
At present, generally, when the oval forceps are used for inserting the anus to pull out the intestinal canal, but for a fat patient or a patient with a tight anus, the force for clamping the intestinal wall by the oval forceps is limited, and the inner wall of the intestinal canal is easy to slip, so that inconvenience and troublesome operation are caused during pulling.
