Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laparoscopic devices face challenges in efficiently closing abdominal wall defects and delivering anesthesia without multiple device interactions or changing deployment modes, leading to increased surgical duration and complications.
Innovation Solution
A dual-deployment suture placement and anesthesia delivery device with integrated channel guides that can be actuated to simultaneously facilitate suture placement and anesthesia injection through multiple pathways, allowing for efficient and simultaneous closure and anesthesia delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional separate devices are used for suture placement and anesthesia delivery, then each device can be optimized for its specific function, but surgical time increases and multiple device interactions are required
Solution Approach 1:
The patent combines suture placement functionality and anesthesia delivery functionality into a single integrated device. The housing contains both a suture channel with guide and an injection needle with deployment mechanism, allowing both functions to be performed through one device insertion and deployment action, eliminating the need for separate devices and reducing surgical time.
Solution Approach 2:
The device is designed to perform multiple functions: it can place sutures through the suture channel and simultaneously or sequentially deliver anesthesia through the injection needle. This multi-functional design allows a single device to replace multiple specialized devices, optimizing workflow and reducing the number of device changes required during surgery.
2Reliability
If multiple devices are used for suture placement and anesthesia delivery, then each device can be independently optimized, but device complexity and ease of operation are reduced
Solution Approach 1:
By merging suture placement and anesthesia delivery into one device, the surgeon interacts with a single integrated system rather than coordinating multiple separate devices. The housing contains both functional elements that can be deployed independently or together, simplifying the operational workflow and reducing the cognitive load of managing multiple device interactions.
3Loss of time
If a single integrated device is used for both suture placement and anesthesia delivery, then surgical time is reduced and ease of operation is improved, but device structural complexity increases
Solution Approach 1:
The integrated device is segmented into distinct functional modules: a housing, a suture channel with guide, and an injection needle with deployment mechanism. Each module is designed independently but integrates seamlessly with the others, allowing the complex functionality to be organized into manageable segments that can be manufactured and assembled separately before final integration.
Solution Approach 2:
The injection needle is nested within the housing, and the suture channel is integrated into the same housing structure. The needle can be deployed from the housing, and the suture guide extends from the housing, creating a compact nested arrangement that reduces overall device complexity while maintaining multiple functions.
4Reliability
If conventional separate procedures are used for port closure and anesthesia injection, then each procedure can be optimized independently, but the number of steps and potential complications increase
Solution Approach 1:
The device enables continuous useful action by allowing suture placement and anesthesia delivery to be performed in a continuous workflow without removing the device or switching to another device. The surgeon can deploy the suture channel and injection needle sequentially or simultaneously while the device remains in place, maintaining continuous productive action and reducing the number of procedural interruptions that could lead to complications.

AI summary
A suture placement device insertable into a surgical port has a cannular housing, and a suture guide mechanism movably connected to a distal housing portion arranged for movement between deployed and non-deployed positions. The mechanism defines first and second receptor port on opposite side portions and a suture passage therebetween that extends the housing distal end portion. First and second channel guides and the suture passage form the suture passage when deployed with portions of the first and second channel guides extending into corresponding receptor ports. Third and fourth channel guides forming injector channels are movable between retracted and deployed positions having portions extending from opposite sides to first and second injection positions. Actuation of a channel guide deployment mechanism attached to the housing and channel guides, such as slide, automatically deploys the first, second, third and fourth channel guides to their deployed positions allowing medicament injections and suture placement.
