Problems solved by technology

[0003] The present invention is more suitable for patients with low rectal cancer, and the incidence of anastomotic leakage after low rectal cancer surgery is also significantly increased. Anus implantation, position the drainage stent above the leakage point of the intestinal anastomosis, and drain the contents in the intestine, so as to reduce the surgical incision and avoid multiple operations of ostomy and fistula. The drainage stent in the prior art does not Applicable to new treatment methods, it is easy to displace the drainage stent and lead to unsuccessful drainage

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, without limiting the present invention.

[0025] Such as Figure 1-6 As shown, the present invention provides a stent for intestinal anastomotic leakage, including a stent body 1, the stent body 1 is in a tubular structure, forming a hollow fluid guiding channel 2, and the material of the stent body 1 is a hard plastic tube. The inner wall of the extension end of the stent is provided with a liquid storage ring 3 for storing the adhesive, and the adhesive is a degradable medical bio-adhesive whose degradation time is close to the healing time of the anastomotic stoma. Preferably adopting the medical bioadhesive that the degradation time is 20-30 days,

[0026] The outer wall of the bracket is provided with a release channel 4 for draining the adhesive, and the liquid storage ring 3 is provided with a glue outlet 5 corresponding to the release c...

Abstract

The invention discloses a stent for intestinal anastomotic stoma leakage. The stent comprises a stent body, wherein the stent body is in a pipe structure and forms a hollow liquid drainage channel; aliquid storing ring for storing an adhesive is arranged on the inner wall of an extending end of the stent; releasing channels for draining the adhesive are formed in the outer wall of the stent body;a glue outlet is formed in the liquid storing ring, corresponding to the releasing channels, and an overlay membrane for sealing the glue outlet is arranged at the glue outlet; an overlay membrane breaking device is arranged in the releasing channels; and an air sac is arranged at the lower ends of the releasing channels, on the outer wall of the stent body. According to the stent disclosed by the invention, when the stent is used, the stent body is transplanted to a position above an anastomotic stoma, and is positioned to the position above the anastomotic stoma through the air sac; the adhesive in the liquid storing ring is released through rotating the overlay membrane breaking device on the liquid storing ring; the air sac is tightly adhered to the inner wall of the intestinal tract,so that position moving is prevented; the integrated operation process is convenient and easy; through the adoption of the anastomotic stoma disclosed by the invention, a doctor can well avoid repeated operations including fistulation and enterostomy closure, and directly drain contents, so that the situation that the anastomotic stoma is polluted and abdomen inflammation is initiated is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a bracket for intestinal anastomosis leakage. Background technique [0002] Rectal cancer is a common malignant tumor of the digestive system, and its incidence is increasing year by year. It has become the third most common tumor after lung cancer and gastric cancer. In recent years, with the continuous improvement of surgical techniques, rectal cancer has been resected and joined with staplers. However, the most common complication of rectal cancer surgery is "anastomotic leakage", with an incidence rate of 5-20%, resulting in a large amount of bacteria. Fecal-like intestinal contents leak into the abdominal cavity, and the infection spreads rapidly in the abdominal cavity, followed by acute peritonitis. In severe cases, septic shock occurs soon, which endangers the lives of patients. In this case, the intestinal contents were diverted in time, and after a few months, the anasto...
