Anti-Reflux Valve With Rotating Plate for GERD Surgery Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand for a medical device that can predict the effectiveness of anti-reflux surgery for gastro-esophageal reflux disease without the inconvenience of pre-surgical tests and ensure a guaranteed surgical outcome.
Innovation Solution
An anti-reflux valve is designed to be inserted into the upper portion of the stomach, featuring a ring-shaped body, a rotatable reflux blocking plate, and a fixing clip to secure it to the gastro-esophagus, with optional biodegradable materials and magnetic or elastic components to facilitate secure attachment and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-reflux surgery is performed, then symptom control and treatment satisfaction are improved, but pre-surgical tests and procedural complexity increase
Solution Approach 1:
The patent applies preliminary action by inserting a test valve into the patient's stomach before actual surgery to predict surgical outcomes. This allows clinicians to assess whether surgery will be effective without performing full pre-surgical testing protocols, thereby simplifying the diagnostic process while maintaining reliable symptom control predictions
Solution Approach 2:
The test valve serves as a simplified copy or model of the actual anti-reflux surgical device. By using this smaller, removable test version, clinicians can evaluate treatment effectiveness without committing to permanent surgical intervention, reducing the complexity of pre-surgical decision-making
2Reliability
If only a small portion of patients undergo surgery, then surgical risks are reduced, but treatment effectiveness for GERD population decreases
Solution Approach 1:
By performing preliminary testing with the insertable test valve, clinicians can identify which patients are likely to benefit from surgery before committing to the procedure. This enables more patients to be appropriately selected for surgery, increasing overall treatment effectiveness without unnecessarily exposing more patients to surgical risks
Solution Approach 2:
The test valve provides feedback to clinicians about a patient's response to temporary valve placement. This feedback mechanism allows for better patient selection and counseling, enabling more informed decisions about which patients should proceed to definitive surgical treatment, thereby improving overall treatment effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The anti-reflux valve effectively prevents reflux of stomach fluids, allowing prediction of surgical outcomes by mimicking the effects of anti-reflux surgery, thereby reducing the need for invasive pre-surgical testing.
Implementation Method 1
a reflux blocking plate coupled to an inner circumferential surface of the body to be rotatable in one direction
Implementation Method 2
a fixing clip coupled to an outer circumferential surface of the body to fix the body to the upper end of the gastro-esophagus
