Rectum anastomotic stoma protection device and operation method

Abstract

The invention relates to a rectum anastomotic stoma protection device and an operation method, and the rectum anastomotic stoma protection device is characterized in that the rectum anastomotic stoma protection device comprises a drainage main pipe, an enteral fixator, a perfusion head, a drainage sleeve film, an in-vitro drainage pipeline, an in-vitro fixing clamp, a collection container, a perfusion pipeline, an inflation pipeline and a negative pressure pipeline, the enteral fixator is installed on outer wall of the drainage main pipe, and the drainage main pipe is provided with a drainage cavity, a perfusion cavity, an inflation cavity and a negative pressure cavity, the upper end of the perfusion cavity is connected with the perfusion head, the lower end of the perfusion cavity is connected with the perfusion pipeline, the upper end of the inflation cavity is of a closed structure, the lower end of the inflation cavity is connected with the inflation pipeline, the upper end of the negative pressure cavity is provided with a negative pressure side hole, the negative pressure side hole is communicated with the outer cavity of the intestinal fixator, and the lower end of the negative pressure cavity is connected with the negative pressure pipeline, the drainage sleeve membrane is connected with the lower end of the drainage cavity, the outer end of the drainage sleeve film is connected with an in-vitro drainage pipeline, and the other end of the in-vitro drainage pipeline is connected with a collection container. The invention has the advantages that the anastomotic stoma can be effectively isolated, patient abdominal cavity infection caused by excrement contacting with the surgical anastomotic stoma is avoided, bypass and secondary reduction surgery are not needed, and the pain of a patient is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a rectal anastomosis protection device and an operation method. Background technique [0002] At present, rectal cancer is usually treated clinically with rectal resection. Complications such as rectal anastomotic infection or anastomotic leakage are prone to occur after the operation, which in turn leads to abdominal infection of the patient. In mild cases, the patient is delayed in leaving the hospital, and in severe cases, the patient’s life is endangered. In order to prevent excreta from contaminating the patient's rectal anastomosis, it is generally necessary to protect the anastomosis. The existing protective anastomotic stoma is relatively common and effective: lift the patient's terminal ileum or transverse colon out of the main abdominal wall, and then make a protective enterostomy on the patient's abdominal wall to form a temporary enterostomy for th...

The above-mentioned method requires a second recovery operation on the patient, which will not only cause secondary injury to the patient, but also take a long recovery period, increasing the patient's physical and mental pain and medical expenses

In the known technology, although there is a clinical method of using a balloon to block the rectal anastomotic stoma, the expansion of the balloon will cause certain expansion and compression effects on the anastomotic stoma, and the smoothness of the balloon will easily cause displacement, which is not conducive to anastomosis Restoration of the mouth and the presence of defects with incomplete drainage of excreta
