Postoperative anastomotic fistula drainage device and negative pressure drainage device

Abstract

The invention discloses a postoperative anastomotic fistula drainage device and a negative pressure drainage device, and relates to the technical field of medical instruments. The postoperative anastomotic fistula drainage device comprises a dressing, a cavity drainage tube and a radiography drainage tube, the dressing is used for filling an incision of a patient, the dressing can absorb body fluid of a patient, the cavity drainage tube penetrates through the dressing in the thickness direction of the dressing, the cavity drainage tube points to an anastomotic sinus tract, the radiography drainage tube penetrates through the cavity drainage tube in the length direction of the cavity drainage tube, and the ends, extending out of the body of the patient, of the radiography drainage tube andthe cavity drainage tube can be communicated with a negative pressure device. In the present invention, the cavity drainage tube can guide the radiography drainage tube, the radiography drainage tubecan extend into the outer opening of an anastomotic sinus tract, the structure of the sinus tract can be conveniently confirmed by radiography of the anastomotic stoma sinus tract, and when the radiography drainage tube stretches into the inner opening of the anastomotic stoma sinus tract, a contrast medium is pushed again and radiography is carried out to confirm whether the radiography drainagetube stretches into the proper position or not, so that accurate drainage can be carried out on anastomotic fistula, and anastomotic fistula is quickly cured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a postoperative anastomotic fistula drainage device and a negative pressure drainage device. Background technique [0002] Postoperative anastomotic leakage is an important problem that plagues the current surgical treatment. For example, postoperative anastomotic leakage in esophageal cancer has become a standard surgical procedure for esophageal cancer. To solve the problem of rapid healing of cervical anastomotic leakage is of great importance. The work of esophageal surgery is of great significance. It usually takes more than a month for traditional dressing change to heal neck anastomotic leakage, and some patients will not heal after dressing change for a long time, and serious complications such as anastomotic tracheal leakage will occur. [0003] In the prior art, the treatment of cervical anastomotic leakage generally involves inserting a double-lumen silicone dr...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the treatment of cervical anastomotic leakage generally involves inserting a double-lumen silicone drainage tube through the neck opening, one lumen is connected to a negative pressure drainage device for continuous negative pressure suction, and the other lumen is used for drainage. For incision irrigation, this method cannot accurately find the anastomotic fistula opening, cannot accurately drain, the drainage effect is not good, and has the disadvantage of poor or insufficient drainage, which makes it difficult for the anastomotic fistula to heal
