Solidifiable Polymer Intestinal Plug for Endoscopic Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During enteroscopic surgical interventions in the intestines, complications arise due to feces interfering with the procedure, making it difficult and risky, as existing materials for temporary intestinal obstruction are not suitable for rapid formation and removal.
Innovation Solution
A method using a solidifiable composition that can be pumped through an endoscope to form a temporary plug within the intestine, utilizing polymers that swell, coagulate, or polymerize to create a stable barrier, which can be removed mechanically, chemically, or physically to allow for unimpeded surgical access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a viscous polymer solution is used to form a temporary obstruction in the intestine, then the obstruction can be formed, but the solution cannot be pumped through the endoscope quickly enough before significant proportions flow past the site to be obstructed
Solution Approach 1:
The patent changes the physical state parameter of the polymer material from a viscous solution to a flowable composition that can be rapidly delivered and then quickly solidifies. This allows the material to be pumped through the endoscope quickly while maintaining the ability to form a reliable obstruction at the target site.
Solution Approach 2:
The patent utilizes phase transition of the polymer composition from a flowable state during delivery to a solidified state at the obstruction site. This phase change enables rapid delivery of the material in a flowable form, followed by quick solidification to form a reliable temporary obstruction, resolving the contradiction between delivery speed and obstruction effectiveness.
2Reliability
If existing materials for temporary intestinal obstruction are used, then obstruction can be formed, but the materials are not suitable for rapid formation and removal
Solution Approach 1:
The patent employs a dynamic material system that transitions from a stable solidified state during the surgical intervention to a removable state afterward. The composition is designed to form a stable obstruction during the procedure but can be quickly removed or dissolved after, addressing the need for both stability during use and rapid removal after the surgical goal is achieved.
Solution Approach 2:
The patent utilizes parameter changes in the polymer composition to achieve both stable obstruction formation and rapid removal. The material's physical or chemical parameters are modified to create a stable state during the intervention and then allow for quick degradation or removal afterward, minimizing time loss.
3Object-affected harmful factors
If a polymer plug is formed to seal the intestine, then feces cannot reach the surgical site, but the plug must be removed after the intervention
Solution Approach 1:
The patent employs a self-removing or self-degrading polymer composition that automatically loses its structural integrity after serving its protective function. The material is designed to dissolve or degrade on its own after the surgical intervention, eliminating the need for complex manual removal procedures and reducing the overall complexity of the system.
Solution Approach 2:
The patent utilizes phase transition or chemical degradation of the polymer plug to enable easy removal after the surgical intervention. The material transitions from a stable solid state during the procedure to a degraded or dissolved state afterward, allowing for simple removal without complex devices or procedures.
