Solution Overview

Problem

Current surgical suturing technologies lack the capability to perform sequential threading operations efficiently, particularly in sensitive areas like heart tissue, requiring improved versatility, reduced procedure time, and minimized complexity and risk.

Innovation Solution

Development of threading devices that can sequentially send or receive multiple carriers, such as needle caps or sleeves, into or from an object, enabling rapid succession and automatic reloading, material anchoring, and knot securing with simultaneous cutting, while minimizing the use of clips and maximizing pre-tied knots.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional manual suture-based tissue approximation is used, then surgical precision and control are maintained, but procedure time increases and surgical efficiency decreases

Engineering Contradiction:
Improvesurgical efficiencyVSAvoidprocedure time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The threading device enables self-service automation where the system automatically loads carriers, positions them, and performs sequential threading operations without requiring manual intervention for each suture stitch, thereby transforming laborious manual suture-based tissue approximation into an automated process that reduces procedure time while maintaining precision

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Multiple carriers are pre-loaded into the device before the surgical procedure begins, allowing the system to perform rapid sequential threading operations without interruption for reloading, thus reducing procedure time and improving surgical efficiency

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If sequential threading operations are performed manually, then control and precision are maintained, but operational complexity and risk increase

Engineering Contradiction:
Improveoperational simplicityVSAvoidthreading device complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The threading device integrates multiple functions including carrier storage, automated carrier ejection, thread guidance, and tissue threading into a single multi-functional system, which simplifies the overall surgical operation while managing the inherent device complexity through functional integration

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device uses intermediate components such as carriers and guide structures that mediate between the surgeon's control inputs and the complex threading operations, simplifying the user interface and ease of operation while the internal mechanism handles the complexity of sequential carrier ejection and thread management

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If multiple carriers are ejected sequentially in rapid succession, then productivity increases, but device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improvethreading speedVSAvoiddevice manufacturing
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The device segments the carrier ejection function into multiple independent carrier components that can be manufactured separately using standard manufacturing processes, then assembled into the sequencing mechanism, thereby achieving rapid sequential ejection while maintaining ease of manufacture through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple carriers are nested or stacked within the device housing in a compact arrangement, allowing rapid sequential ejection without requiring excessive device volume or complex manufacturing, thus improving threading speed while managing manufacturing complexity through space-efficient design

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

This disclosure enables various threading devices (e.g., suturing devices) that can sequentially send a plurality of carriers (e.g., needle caps, sleeves) to an object (e.g., animate, inanimate, human tissue, organ tissue, heart tissue) or sequentially receive a plurality of carriers (e.g., needle caps, sleeves) from an object (e.g., animate, inanimate, human tissue, organ tissue, heart tissue). For example, some threading devices can sequentially send some carriers in a relatively rapid succession or some threading devices can sequentially receive some carriers in a relatively rapid succession.
