Flexible Endoscope Lateral Wall Access via Rotational Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible endoscopic diagnosis and treatment methods face challenges in accessing and visualizing the lateral walls of organs such as the hypopharynx, larynx, trachea, bile duct, pancreatic duct, duodenum, stomach, esophagus, urethra, bladder, ureter, renal pelvis, vagina, and uterus, due to difficulties in inserting and maneuvering endoscopes through narrow or obstructed pathways, leading to incomplete diagnoses and invasive procedures.
Innovation Solution
A method involving rotating the patient's body position and manipulating the flexible endoscope to access lateral walls by rotating the endoscope 45 to 90 degrees, allowing for visualization and treatment of previously inaccessible areas, including the use of specific devices like balloon catheters and laser catheters for dilation and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional flexible endoscopic methods are used to access hollow organs, then the procedure can be performed with minimal invasion, but the lateral walls of organs cannot be adequately visualized or accessed
Solution Approach 1:
The patent introduces a rotational dimension to endoscope manipulation by changing patient body position (supine, lateral, prone) to rotate the hollow organ, enabling the endoscope to access lateral walls that are otherwise inaccessible from a straight-ahead approach. This dimensional change in positioning enables comprehensive visualization of all organ surfaces.
Solution Approach 2:
The patent employs dynamic manipulation of both the patient's body position and the endoscope's rotational angle during the procedure. By continuously adjusting these parameters, the system adapts to access different portions of the organ, particularly the lateral walls, transforming a static examination into a dynamic multi-angle assessment.
2Ease of operation
If the endoscope is inserted through narrow or obstructed pathways, then minimally invasive access is achieved, but maneuvering to lateral walls becomes difficult
Solution Approach 1:
By adding the rotational degree of freedom through body position changes, the system can reach lateral walls without requiring the endoscope to physically navigate around corners or through tight spaces. The rotation brings different organ surfaces into the endoscope's forward-viewing path.
Solution Approach 2:
The combined approach of body position adjustment and endoscope rotation creates a universal method that can access any surface of any hollow organ through a single insertion point, making the procedure adaptable to various organ geometries and pathological conditions without requiring multiple access routes.
3Manufacturing precision
If invasive surgical procedures are used to access lateral walls, then complete visualization is achieved, but patient trauma and recovery time increase
Solution Approach 1:
The patent achieves complete lateral wall visualization through non-invasive rotational positioning and endoscope manipulation, eliminating the need for incisions or tissue disruption that would be required by traditional surgical approaches. Diagnosis accuracy is maintained while avoiding surgical trauma.
Solution Approach 2:
The patent replaces mechanical surgical dissection and retraction with optical visualization achieved through rotational positioning. Instead of physically cutting or moving tissue to expose lateral walls, the system uses controlled rotation and flexible endoscope maneuvering to bring hidden surfaces into view.

AI summary
A device insertion method for observing the lateral wall of the lumen includes: rotating a hollow organ by changing a body position; turning the tip of the device to the lateral wall of the lumen by rotating the device; and retracting the organ with the device itself by rotating the device, In other embodiments, an endoscope insertion method for observing the lateral side of the organ includes: rotating a body cavity by changing a body position; turning the tip of the flexible endoscope to the lateral side of the organ by rotating the flexible endoscope; and retracting the organ with the flexible endoscope itself by rotating the flexible endoscope.
