Surgery Drainage Tube with Cuttable Limiting Component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgery drainage tubes frequently become displaced from anastomotic stomas due to postoperative body position changes and intestinal movements, leading to ineffective drainage and increased risk of abdominal infection.
Innovation Solution
A detachable surgery drainage tube with a hollow tube body, an inelastic annular first limiting component, and a suture line that can be fixed to the anastomotic stoma, ensuring stable positioning and easy removal by cutting the first limiting component, which is detachably connected to the tube body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drainage tube is placed around the anastomotic stoma during surgery, then drainage effect is achieved, but the tube becomes displaced due to body position changes and intestinal movements
Solution Approach 1:
The suture line is pre-configured on the drainage tube body, extending from the outer surface through the hollow interior. This preliminary arrangement allows the tube to be securely anchored to the anastomotic stoma during surgery, preventing displacement caused by body position changes and intestinal movements while maintaining reliable drainage function.
2Stability of the object's composition
If the drainage tube is securely fixed to maintain position, then stability is improved, but removal and adjustment become difficult
Solution Approach 1:
The drainage tube is divided into functional segments: a fixed portion (tube body with suture line for stable positioning) and a detachable portion (first limiting component that can be cut). This segmentation allows the tube to be securely fixed during the drainage period while enabling easy removal by cutting the limiting component when drainage is no longer needed.
Solution Approach 2:
The first limiting component is designed to be detachable and easily cut by scissors. When the drainage function is complete, the limiting component can be discarded by cutting, allowing for simple tube removal without causing tissue damage, while the main tube body and suture line can be recovered if needed.
3Stability of the object's composition
If the tube body is made rigid to maintain shape, then structural stability is improved, but flexibility for positioning is reduced
Solution Approach 1:
The tube body exhibits local quality differentiation: the main tube structure maintains rigidity to preserve its cylindrical shape and structural integrity, while the suture line and limiting components provide localized flexibility for positioning and securing. This allows the tube to maintain its form while adapting to the surgical site requirements.

AI summary
The present disclosure provides a detachable surgery drainage tube capable of being sutured and fixed, relates to a technical field of surgery drainage tubes, including a tube body, a suture line, and a first limiting component. The tube body is hollow. The suture line has a length, and is configured to act on a part to be drained. The first limiting component is an annular structure, and a structure of the first limiting component is easy to be cut by scissors. The first limiting component is disposed in the tube body, and two ends of the first limiting component are fixed at two ends of the tube body. A fixing component is disposed on the tube body with respect to the first limiting component, a fixing groove is disposed on the fixing component, the fixing groove is perforated, and the first fixing component penetrates through the fixing groove.
