Integrated Port Closure with Sequential Suture Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laparoscopic wound closure devices often require multiple components and separate tools for anchoring, piercing, and grasping sutures, leading to complexity and inefficiency in surgical procedures.
Innovation Solution
An integrated wound closure device with a single elongated body that combines anchoring, piercing, and grasping functions, using a sequential selector system to operate these functions sequentially, allowing for efficient and streamlined wound closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate components (suture guide, grasper, anchoring device) are used for wound closure, then each component can be optimized for its specific function, but the overall device complexity and number of components increases
Solution Approach 1:
The patent combines the suture guide, grasper, and anchoring device into a single integrated wound closure device. The guide channels, grasper mechanism, and anchoring members are all incorporated into one elongated body structure, eliminating the need for multiple separate components while maintaining all necessary functions for wound closure
Solution Approach 2:
The integrated device performs multiple functions through a single unified structure. The elongated body simultaneously provides guidance for sutures, houses the grasper for capturing suture material, and incorporates anchoring members for securing the device. This multi-functional design reduces component count while achieving the same clinical objectives
2Reliability
If multiple separate tools are used for anchoring, piercing, and grasping, then each tool can be specialized, but the surgical procedure time and efficiency decreases
Solution Approach 1:
The patent merges the anchoring, piercing, and grasping functions into a single device that can perform all operations sequentially without requiring tool changes or removal of previous components. The integrated design allows the surgeon to complete the entire wound closure process using one device, thereby improving surgical efficiency
3Device complexity
If a single integrated device is used for all wound closure functions, then device complexity is reduced, but the ease of operation for each individual function may be compromised
Solution Approach 1:
The integrated device is divided into distinct functional segments along its elongated body. Each segment (guide channels, grasper mechanism, anchoring members) is spatially separated and can be independently activated or operated. This segmentation allows each function to be performed with dedicated control while maintaining the benefits of an integrated design

AI summary
A novel integrated wound closure device for laparoscopy having an elongated body with a distal end and proximal end able to-use suture for closing surgical port wounds comprising a single sequential proximal activation means able to operate multiple internal systems sequentially such as: a distal anchoring system, a self-contained tissue piercing system, a suture staging means to position suture suitable for capture at a target zone, and a suture capturing system to capture and retract suture into said piercing system with all system functions configured internally of said elongated body which can be reused multiple times per patient.
