Endoluminal Colostomy Reversal Stabilization and Anastomosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current colostomy reversal procedures are invasive, leading to increased trauma and morbidity for patients.
Innovation Solution
A novel surgical procedure and apparatus that uses an access device to stabilize the intestinal lumen and an anastomosis instrument to reconnect intestinal sections, reducing invasiveness by maintaining patency and precision during the reversal process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional invasive colostomy reversal procedures are used, then the intestinal sections can be reconnected, but patient trauma and morbidity increase
Solution Approach 1:
The patent replaces traditional open surgical mechanical dissection with a minimally invasive endoluminal approach using specialized instruments introduced through natural orifices. The anastomosis is performed using a stapling device that fires staples through the intestinal wall from within the lumen, avoiding external incisions and reducing mechanical trauma to tissues.
Solution Approach 2:
The patent employs a flexible endoluminal access device with a thin-walled structure that can be inserted through natural body orifices and navigated to the target site within the intestinal tract. This flexible shell approach allows the surgical instrument to reach the intestinal sections without requiring large external incisions, thereby reducing patient trauma.
2Manufacturing precision
If traditional surgical techniques are used for colostomy reversal, then intestinal continuity is restored, but the procedure complexity and invasiveness increase
Solution Approach 1:
The patent employs a multi-functional endoluminal device that combines access, stabilization, and anastomosis functions in a single integrated system. The device can perform multiple surgical tasks including positioning, lumen stabilization, and stapling through a unified platform, reducing the number of separate instruments and procedures needed while maintaining precision.
Solution Approach 2:
The patent introduces an endoluminal access device as an intermediary that facilitates the connection between intestinal sections. This mediator device provides a controlled environment within the lumen for performing the anastomosis, allowing precise positioning and stabilization of the intestinal wall during the reconnection process without requiring complex external surgical manipulation.
3Stability of the object's composition
If the intestinal lumen is not stabilized during reconnection, then the procedure is less complex, but patency cannot be maintained during the procedure
Solution Approach 1:
The patent employs a nested structure where the stabilization component is integrated within the endoluminal access device. The stabilization element can be deployed from within the access device body, allowing the lumen to be stabilized without requiring a completely separate external support structure. This nested approach maintains patency while minimizing overall device complexity.
Solution Approach 2:
The stabilization component is designed to be self-expanding or self-adjusting once deployed within the lumen. The device automatically adapts to the lumen geometry and provides stabilization without requiring continuous external control or complex actuation mechanisms, thereby maintaining patency while keeping the device structure relatively simple.

AI summary
A trocar for positioning within a body lumen such as an intestine is disclosed. The trocar has a window adjacent its distal end in communication with the internal lumen of the trocar. The trocar is sufficient rigid to stabilize the body lumen upon positioning therein to maintain patency of the body lumen. A slot in communication with the window extends to the distal end of the trocar.A surgical procedure for reversing a colostomy procedure is also disclosed. The above described trocar is inserted into a first intestinal section through an opening in the abdominal wall. A guide wire is introduced through the rectal opening and advanced through the rectal stump and out the opening in the abdominal wall. An anvil is connected to the guide wire and the guide wire withdrawn through the rectal opening to advance the anvil within the first intestinal section. An anastomosis instrument is introduced through the rectal opening and connected to the anastomosis instrument. The anastomosis instrument is fired to connect the two intestinal sections to reestablish continuity between them.
