Detachable Handle Segments for Endoscopic Cannula Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscopic access systems often limit the ability to maneuver medical devices to desired angles and orientations due to the handle's design, restricting access to internal organs and effective procedure execution.
Innovation Solution
An endoscopic access system featuring a detachable handle with a flexible cannula and a stylet, allowing the proximal handle segment to be uncoupled from the distal segment, enabling free manipulation of the cannula for precise angle adjustments and orientation, facilitated by interlocking elements, slots, or other mechanisms for enhanced maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle is designed as a single integrated unit, then the device structure is simple and reliable, but the ability to maneuver the medical device to desired angles and orientations is limited
Solution Approach 1:
The handle is divided into a proximal handle segment and a distal handle segment that can be coupled together or separated. This segmentation allows the distal segment to remain attached to the medical device for stability, while the proximal segment can be detached to provide unrestricted maneuverability and access to desired angles and orientations during the procedure.
2Adaptability or versatility
If the proximal handle segment remains coupled to the distal handle segment, then the device maintains structural integrity, but the flexibility and freedom of manipulation of the cannula is restricted
Solution Approach 1:
The coupling between the proximal and distal handle segments is made dynamic rather than fixed. The segments can be coupled together to maintain structural integrity during insertion and initial positioning, then uncoupled when flexibility and freedom of manipulation are needed for complex procedures requiring varied angles and orientations.
3Ease of operation
If the handle design provides stable support for the medical device, then the device is easy to control, but access to internal organs at various angles and orientations is limited
Solution Approach 1:
By segmenting the handle into detachable proximal and distal segments, the system provides stable support when segments are coupled during insertion, then enables access to internal organs at various angles and orientations when the proximal segment is detached and can be maneuvered freely without constraints.

AI summary
The present embodiments provide an endoscopic access system comprising a handle including a proximal handle segment and a distal handle segment. A sheath extends distally from the distal handle segment. A flexible cannula having proximal and distal ends and lumen extending therebetween is sized to be advanced through a lumen of the sheath. The handle has a coupled state in which the proximal handle segment is engaged to the distal handle segment, and where the flexible cannula is disposed through at least a portion of both the proximal and distal handle segments. The handle further has an uncoupled state in which the proximal handle segment is disengaged from the distal handle segment, and where the flexible cannula is disposed only through the distal handle segment.
