Integrated Endoscope with 3D Imaging and Single Incision Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscopic surgery requires multiple incision windows due to the need for separate insertion of endoscopes and surgical instruments, increasing the surgical site diameter and complicating procedures like diagnosis and treatment through natural openings.
Innovation Solution
A device featuring a main tube with integrated first and second cameras, a light source, and therapeutic instruments that can be inserted through a single incision, allowing for the expansion of instruments within the body while minimizing the incision site, and incorporating washing modules for clear three-dimensional imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate instruments (endoscope and surgical instruments) are inserted through separate incision windows, then each instrument can be independently operated, but the number of incision windows increases and the surgical site diameter increases
Solution Approach 1:
The patent combines multiple separate instruments (endoscope, surgical instruments, illuminating devices) into a single integrated endoscope system. The endoscope body integrates the imaging device, illuminating device, and surgical instrument channels, allowing all functions to be delivered through one incision window rather than multiple separate incisions.
Solution Approach 2:
The endoscope is designed as a universal platform that performs multiple functions: imaging (first and second photographing devices for 3D visualization), illuminating (illuminating device), and surgical intervention (surgical instrument insertion channels). This multi-functional design eliminates the need for separate specialized instruments and incisions.
2Area of stationary object
If instruments are linearly installed on one plane in one tube, then only one incision window is needed, but the tube diameter must be enlarged
Solution Approach 1:
The patent transitions from linear planar arrangement to three-dimensional spatial arrangement. The endoscope body incorporates multiple functional components arranged in three dimensions: photographing devices at different positions, illuminating devices at multiple locations, and surgical instrument channels extending in different directions. This 3D arrangement allows compact integration without increasing the external diameter excessively.
Solution Approach 2:
The endoscope employs a nested structure where multiple functional components are housed within the endoscope body. The surgical instruments are inserted through channels within the endoscope body, the illuminating devices are positioned within the housing, and the photographing devices are integrated at the tip. This nested arrangement maximizes space utilization while maintaining a compact overall diameter.
3Area of moving object
If the cross-sectional area of the endoscope is made as small as possible, then natural openings or small incision windows can be used, but the diameter of the tube must be reduced
Solution Approach 1:
The endoscope is segmented into multiple functional modules: first photographing device, second photographing device, illuminating devices, and multiple surgical instrument channels. Each module is independently designed and positioned within the endoscope body, allowing optimized space utilization and maintaining small cross-sectional area while preserving all necessary functions.
4Length of stationary object
If photographing parts are folded inside the pipe-shaped body and spread in the human body, then the diameter of the body is decreased, but an additional incision window is needed for treatment instruments
Solution Approach 1:
The patent merges the surgical instrument insertion function directly into the endoscope body by providing surgical instrument channels within the endoscope structure. This integration allows surgical instruments to be delivered through the same incision window as the endoscope, eliminating the need for additional separate incisions for treatment instruments.
