Embodiment 1

[0030] Such as Figure 1-4 As shown, this embodiment provides a treatment device for anastomotic leakage, including a first drainage tube 1 , an annular balloon 2 , a balloon tube 3 and a valve 4 .

[0031] The first drainage tube 1 comprises a drainage section 101 and a plugging liquid suction section 102, the plugging liquid suction section 102 is fixedly arranged at the bottom of the drainage section 101, the first drainage tube 1 is made of elastic material, and the blocking liquid suction section 102 can be completely plugged Into the lumen of the drainage section 101, the plugging suction section 102 is deployed on the outside of the fistula to attract the residual cavity effusion, and a through hole is provided on the tube wall of the drainage section 101 near the end of the blocking suction section 102; The annular balloon 2 is fixedly arranged on the outer wall of the end of the drainage section 101 close to the sealing liquid absorption section 102, and the annular b...

Embodiment 2

[0039] Such as Figure 5 As shown, the present embodiment provides a device for treating anastomotic leakage, which has roughly the same structure as that in Embodiment 1, the difference is that the blocking liquid suction section 102 is an ellipsoid, and the central axis of the drainage section 101 passes through the ellipsoid vertically. In the center of the long axis of the ellipsoid, a plurality of evenly spaced suction through-holes are arranged on the ellipsoid, and the residual cavity effusion can flow into the lumen of the drainage section 101 through the liquid-suction through-holes. Through a plurality of evenly spaced suction through holes, the suction area is effectively enlarged, and the negative pressure suction effect and the drainage effect on the residual cavity outside the fistula opening are improved.

Abstract

The invention discloses an anastomotic fistula treatment device. The anastomotic fistula treatment device comprises a first drainage tube, an annular balloon, a balloon tube and a valve, wherein the first drainage tube comprises a drainage section and a plugging liquid suction section, the plugging liquid suction section is fixedly arranged at the bottom of the drainage section, and the first drainage tube is made of an elastic material; the annular balloon is fixedly arranged on the outer wall of one end, close to the plugging liquid suction section, of the drainage section; one end of the balloon tube extends from the top of the drainage section, extends out of a through hole and then communicates with the annular balloon, and the balloon tube is fixedly arranged on the inner wall of the drainage section; and the valve is installed at the end, away from the annular balloon, of the balloon tube. Compared with the prior art, the anastomotic fistula treatment device can effectively block fistula, prevent anastomotic stoma stenosis, suck residual cavities and residual fistula and achieve the purpose of fast healing of the anastomotic stoma.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a treatment device for anastomotic leakage. Background technique [0002] Esophagogastric anastomotic leakage refers to the local defect of esophagogastric anastomosis after esophagus or proximal gastrectomy for esophageal cardia cancer or other diseases. After esophageal, gastric, intestinal and other digestive tract tumors or other diseases, due to various reasons, the anastomotic stoma will become narrower, causing obstruction and other related complications of the anastomotic stoma. of scar hyperplasia. [0003] Chinese Patent Document No. CN102551818A discloses an esophagus-gastric anastomotic fistula occluder and its application, including a gastric tube, a columnar balloon, an annular balloon and a stent, the stent is fixed on the gastric tube, and the balloon is inflated or inflated After water, the fistula is directly blocked in the esophagus and stomach, b...
