Endoscopic Closure Device with Movable Support for Tissue Defects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscopic suturing techniques are limited, and existing surgical closure devices struggle to effectively align and deploy along the axis of an endoscope accessory channel, particularly in closing larger tears or defects, due to fixed relationships and difficulties in positioning.
Innovation Solution
A surgical closure device featuring a pair of grasping members coupled to a support member, allowing movement along the axis of the endoscope, with a ratcheting mechanism for incremental closure and deployment, enabling the device to be aligned and deployed parallel to the endoscope accessory channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional endoscopic suturing techniques are used, then tissue closure can be achieved, but the ability to align and deploy along the endoscope accessory channel axis is limited
Solution Approach 1:
The patent applies dynamics by making the support member movable relative to the endoscope accessory channel. The support member can move along the longitudinal axis of the endoscope, allowing dynamic adjustment of the grasping members' position. This resolves the contradiction by enabling alignment along the endoscope axis while maintaining structural flexibility rather than using a fixed relationship.
Solution Approach 2:
The device is segmented into distinct components: the endoscope accessory channel, the movable support member, and the grasping members. This segmentation allows each component to perform its specific function independently while working together as a system, improving ease of operation without excessive complexity.
2Adaptability or versatility
If existing surgical closure devices are used, then tissue closure is possible, but the ability to span larger defects is limited due to fixed relationships
Solution Approach 1:
The movable support member enables the device to adapt to larger defects by allowing dynamic adjustment of the distance between grasping members. The support member can be positioned at different locations along the endoscope axis, providing versatility for closing defects of varying sizes while avoiding the complexity of multiple fixed-configuration devices.
Solution Approach 2:
The patent changes the parameter of distance between grasping members by allowing the support member to move along the endoscope axis. This parameter adjustment enables the device to span larger defects when needed while maintaining simplicity through a single movable component rather than complex fixed structures.
3Measurement precision
If conventional closure devices with fixed relationships are used, then structural simplicity is maintained, but positioning precision is reduced
Solution Approach 1:
The movable support member provides dynamic positioning capability, allowing precise placement of grasping members at different locations along the endoscope axis. This dynamic adjustment improves positioning precision while maintaining relatively simple device complexity through a straightforward linear movement mechanism.
