Biological Adhesive Patch Deployment Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hernia repair surgeries require invasive techniques, leading to prolonged recovery times and increased trauma to the patient, as existing methods for attaching patches to biological tissue are often rigid and disruptive to tissue interfaces.
Innovation Solution
A deployment and attachment device (DAD) with a glue dispensing system that laterally deploys a patch and attaches it to biological tissue using a biological glue, featuring a deployment mechanism with reversible frame arms and a glue reservoir system for homogeneous glue distribution along the patch margins, allowing for minimal invasive and reversible attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional rigid anchors (clips, staples, sutures) are used to attach patch to tissue, then attachment strength is improved, but tissue disruption and trauma increase
Solution Approach 1:
The patent replaces traditional mechanical anchoring systems (clips, staples, sutures) with a chemical bonding system using biocompatible adhesive. The adhesive is delivered through a dispensing device that applies the bonding agent directly to the tissue-patch interface, eliminating the need for mechanical penetration or compression of tissue. This substitution reduces tissue trauma while maintaining attachment strength through chemical adhesion rather than mechanical fixation.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical (rigid anchors) to chemical (adhesive bonding). This parameter change involves selecting appropriate adhesive properties such as viscosity, curing time, and bonding strength to achieve effective attachment without tissue disruption. The adhesive formulation and application parameters are optimized to provide strong bonding while minimizing harm to biological tissue.
2Reliability
If invasive surgical techniques are used for hernia repair, then effective corrective surgery is achieved, but recovery time and patient trauma increase
Solution Approach 1:
The patent employs a minimally invasive delivery system that uses a catheter-based approach with adhesive bonding instead of open surgical incisions and mechanical anchoring. The adhesive delivery device can be inserted through small access points, and the adhesive is delivered directly to the repair site, enabling effective hernia repair with significantly reduced surgical trauma and faster patient recovery compared to traditional open surgery.
3Ease of operation
If multiple ports are used in laparoscopic surgery, then surgical instrument access is improved, but surgical complexity and procedure time increase
Solution Approach 1:
The patent integrates multiple functions into a single adhesive delivery device. The device combines adhesive storage, adhesive delivery through controlled dispensing, and patch attachment capabilities in one integrated system. This multi-functional device can be delivered through a single port, eliminating the need for multiple separate instruments and ports, thereby reducing surgical complexity while maintaining ease of operation.
Solution Approach 2:
The patent merges the functions of adhesive storage, adhesive delivery, and patch attachment into a single integrated device. The adhesive reservoir, dispensing mechanism, and attachment features are combined in one unit that can be delivered through a single access point, simplifying the surgical procedure by reducing the number of required ports and instruments while maintaining operational effectiveness.
