Drainage Tube Guide for Stable Extraperitoneal Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage tubes often become dislodged from their fixed position due to intestinal movement, failing to effectively drain fluids and secretions, and current methods like suturing to the peritoneum do not provide significant improvement.
Innovation Solution
A drainage tube guide device that guides the tube through the extraperitoneal fat tissue plane using a head part, guide tube, and peeling portion to minimize tissue damage, allowing secure placement outside the abdominal cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drainage tube is inserted directly into the abdominal cavity through the peritoneum, then the drainage function is initially effective, but the tube becomes dislodged due to intestinal movement (peristalsis)
Solution Approach 1:
The drainage tube is divided into multiple segments: an external portion outside the abdominal cavity, a guide tube portion, and an internal drainage portion. The guide tube acts as a separate auxiliary structure that directs the drainage tube through the preperitoneal space without requiring peritoneum penetration, thereby maintaining stability while reducing tissue damage.
Solution Approach 2:
The guide tube serves as an intermediary device that facilitates the insertion and positioning of the drainage tube through the preperitoneal fat tissue plane. This intermediate structure enables the drainage tube to reach its target position without directly penetrating the peritoneum, thus avoiding the harmful effects of peritoneum damage while ensuring proper placement.
2Object-affected harmful factors
If the drainage tube is moved to an extraperitoneal route through the preperitoneal fat tissue plane, then tissue damage is minimized, but existing technology cannot guide the tube to the target point
Solution Approach 1:
The guide tube acts as an intermediary tool that simplifies the operation of guiding the drainage tube through the preperitoneal space. By providing a pre-formed pathway and directional guidance, the guide tube makes the extraperitoneal routing operation easier and more precise, eliminating the technical limitation of existing methods.
Solution Approach 2:
The guide tube is inserted first to create a prepared pathway through the preperitoneal fat tissue plane before the drainage tube is introduced. This preliminary action establishes a safe and accessible route, making subsequent drainage tube insertion easier and more accurate without damaging underlying tissues or organs.
3Reliability
If the drainage tube is fixed by suturing to the peritoneum, then the tube position is stabilized, but the method does not show significant improvement and causes additional tissue damage
Solution Approach 1:
The drainage tube is extracted from the traditional intraperitoneal routing and repositioned to an extraperitoneal route through the preperitoneal space. By removing the tube from the peritoneal environment, the need for peritoneal suturing is eliminated, thereby stabilizing the tube without causing additional peritoneum damage.
Solution Approach 2:
Instead of fixing the drainage tube by suturing it to the peritoneum from inside the abdominal cavity, the invention inverts the approach by routing the tube externally through the preperitoneal space and securing it outside the peritoneum. This inverted routing strategy achieves stabilization without the harmful effects of peritoneal suturing.

AI summary
A drainage tube guide device is provided, the device including a head part extending in one direction, a guide tube with a hollow formed therein and extending downward from the head part, and a drainage tube fixed to an end of the guide tube, the drainage tube being configured to dissect tissue at the front during introduction, and, once integrally coupled to the guide tube and reaching the target point, having its end removed.
