A suture-fixed and removable drainage tube

Abstract

An embodiment of the present invention provides a suturable, fixed and detachable drainage tube, which belongs to the technical field of drainage tubes, and includes a tube body and sutures, the tube body is hollow; the sutures have a certain length and act on the part to be drained , the suturable and fixed drainage tube also includes: a first limiting member, the first limiting member is an annular structure, and the structure of the first limiting member can be destroyed by external force; the first limiting member The positioning part is arranged in the tube body, and the two ends of the first limiting part are fixed on the two ends of the tube body; wherein, the tube body is provided with a fixing part relative to the first limiting part, and the fixing part is provided with Through the fixing groove, the first limiting member passes through the fixing groove; the tube body is provided with a through hole, and the suture thread passes through at least one side of the first limiting member through the through hole; to achieve drainage The technical effect of stabilizing the position of the tube relative to the anastomotic stoma.

Description

technical field [0001] The invention relates to the technical field of drainage tubes, in particular to a suturable, fixed and removable drainage tube. Background technique [0002] Anastomotic leakage is the most common serious complication after gastrointestinal surgery (such as gastric cancer, colon cancer, and rectal cancer surgery), and it is also one of the leading causes of patient death. Taking colorectal cancer surgery as an example, according to statistics, the incidence of anastomotic leakage after colorectal surgery is as high as 3% to 6%. / 3. Anastomotic leakage after colorectal resection usually occurs within 4-9 days after operation, and in a small number of patients, it can also occur about 10 days after operation. The causes of anastomotic leakage are generally divided into: poor blood supply of the anastomosis, excessive tension of the anastomosis, and poor intestinal preparation. Patients with chronic wasting diseases such as diabetes, malnutrition or l...

AI Technical Summary

Problems solved by technology

During the operation, the drainage tube is usually placed around the anastomotic stoma, but due to postoperative changes in the patient's body position, flatulence and intestinal peristalsis, the drainage tube often shifts, losing its drainage effect and protective effect on the anastomotic stoma

[0004] Therefore, the technical problem of the prior art is: the displacement of the drainage tube relative to the anastomotic stoma
