Postoperative anastomotic leakage drainage device and negative pressure drainage device

Abstract

The invention discloses a drainage device for postoperative anastomotic fistula and a negative pressure drainage device, which relate to the technical field of medical devices and include a dressing, a cavity drainage tube and an angiographic drainage tube. The dressing is used to fill the incision of a patient, and the dressing can absorb The patient's body fluid, the cavity drainage tube passes through the dressing along the thickness direction of the dressing, the cavity drainage tube points to the anastomotic sinus, the angiographic drainage tube runs through the cavity drainage tube along the length direction of the cavity drainage tube, the angiographic drainage tube and the cavity One end of the drainage tube extending out of the patient's body can be communicated with the negative pressure device. In the present invention, the cavity drainage tube can guide the angiographic drainage tube, so that the angiographic drainage tube can extend into the outer orifice of the anastomotic sinus, which is convenient for angiography of the anastomotic sinus to confirm the structure of the sinus. When it extends into the internal opening of the anastomotic sinus, the contrast agent is pushed again and angiography is performed to confirm whether the contrast drainage tube is extended in place, so that the anastomotic leakage can be accurately drained and the anastomotic leakage can be quickly cured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drainage device for postoperative anastomotic fistula 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 of esophageal cancer, in the case that cervical anastomosis has become the standard resection of esophageal cancer, the rapid healing of cervical anastomotic leakage is very important. Esophageal surgery is of great significance. Traditional dressing changes for the treatment of cervical anastomotic fistula usually take more than one month to heal, and some patients do not heal for a long time after dressing changes, resulting in serious complications such as anastomotic tracheal fistula. [0003] In the prior art, the treatment of cervical anastomotic fistula is generally as follows: opening the nec...

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
