Endoscopic Sliding Guide for Independent Accessory Channel Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional endoscopes limit physicians' ability to independently control accessory channels and instruments due to fixed lengths, requiring assistance for precise movements, especially during procedures like cannulation, where fine and coarse adjustments are necessary.
Innovation Solution
An endoscopic device with a sliding guide and track system within the handle allows for independent movement of accessory channels and instruments, incorporating a roller assembly and motorized mechanism for precise control, enabling both fine and coarse movements without needing a second hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the accessory channel is made fixed in length and position, then the device structure is simple, but the physician cannot independently control the accessory channel movement
Solution Approach 1:
The accessory channel system is divided into multiple segments: the accessory channel itself, the sliding guide, and the track. This segmentation allows each component to move independently along the track, enabling the physician to control the accessory channel's position separately from the endoscope body, thus achieving independent control while maintaining manageable structural complexity.
Solution Approach 2:
The accessory channel is transformed from a fixed structure to a dynamic one by introducing the sliding guide that moves along the track. This allows the accessory channel to change its position relative to the endoscope body during the procedure, providing the physician with independent control capability while the overall system structure remains relatively simple.
2Ease of operation
If the physician uses one hand to control the endoscope, then the operation is simplified, but the accessory channel cannot be controlled simultaneously
Solution Approach 1:
The sliding guide is designed to move along the track through the natural manipulation of the accessory channel by the physician's hand. The system uses the physician's own hand movements to control both the endoscope and the accessory channel position, eliminating the need for a second hand or assistant while maintaining simultaneous control capability.
Solution Approach 2:
The control functions for the endoscope and the accessory channel are merged into a single operational interface. The sliding guide mechanism allows the physician to control both components through one hand's movements, combining multiple control functions into a unified system that maintains versatility while simplifying operation.
3Measurement precision
If fine adjustment capability is provided, then precision is improved, but the speed of movement is reduced
Solution Approach 1:
The sliding guide mechanism provides dynamic control where the physician can adjust the speed and precision of movement based on procedural needs. The mechanical design allows for both slow, precise movements when needed and faster movements when the procedure requires quicker repositioning, maintaining adaptability between precision and speed requirements.

AI summary
An endoscopic device is provided. The endoscopic device may comprise a distal end and a proximal end. The proximal end may be opposite the distal end. The endoscopic device may further comprise a handle at the proximal end and a tube extending from the handle towards the distal end of the endoscopic device. The endoscopic device may further comprise an accessory channel. The accessory channel may extend through the tube. The endoscopic device may further comprise a slide, the accessory channel connected to the slide, and a track disposed adjacent to the proximal end of the endoscopic device. The slide is movable within the track to cause movement of the accessory channel within the tube.
