Articulating Patch Deployment Device for Hernia Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for hernia repair during laparoscopic surgery lack the ability to articulate and optimally position surgical patches relative to the tissue, leading to inefficiencies in deployment and attachment, which can result in prolonged recovery times and increased trauma to the patient.
Innovation Solution
An articulating lateral deployment device (ALDD) that allows for bidirectional and reversible deployment of a patch within the abdominal cavity, featuring a central shaft with hinge-like connections and deployment arms that can transform between parallel and perpendicular configurations, enabling controlled and flexible positioning of the patch relative to the hernia defect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surgical incision through major abdominal muscles is used for hernia repair, then effective corrective surgery is achieved, but patient trauma is intense and recovery time is extended
Solution Approach 1:
The surgical approach is segmented into multiple small port incisions rather than one large incision, allowing insertion of specialized deployment devices that can deliver patches minimally invasively while maintaining repair effectiveness
Solution Approach 2:
A deployment device acts as an intermediary tool that delivers the patch through small ports to the hernia defect site, enabling minimally invasive placement without requiring direct surgical exposure through large incisions
2Object-affected harmful factors
If laparoscopic surgery with small ports is used, then patient trauma is reduced and recovery is faster, but the ability to articulate and position patches optimally is limited
Solution Approach 1:
The deployment device incorporates articulating joints and movable deployment arms that can dynamically adjust their configuration, allowing the patch to be positioned at various angles and orientations relative to the hernia defect while maintaining minimal invasiveness
Solution Approach 2:
The deployment arms can change their angular parameters and relative positions, transforming between different configurations to achieve optimal patch alignment with the hernia defect from various approaches through the small ports
3Length of moving object
If the patch is attached to a balloon for deployment, then the patch can be delivered through small ports, but the system lacks flexibility to fit the tissue landscape
Solution Approach 1:
The deployment system is segmented into multiple independent deployment arms rather than a single rigid balloon structure, allowing each arm to independently articulate and adapt to the tissue landscape while delivering the patch through small ports
Solution Approach 2:
The deployment arms incorporate articulating joints that provide dynamic flexibility, enabling the system to conform to the three-dimensional tissue landscape and hernia defect geometry while maintaining delivery through minimally invasive ports
