Suture Locking Device With Automated Compression

Solution Overview

Problem

The manual knotting of sutures in medical procedures is difficult, requires high technical skill, and prolongs operation time, increasing the risk of complications.

Innovation Solution

A suture locking device with a suture pressing housing, squeezing part, and driving component that automatically locks sutures by squeezing them between the squeezing part and the cavity wall, facilitated by an implanting apparatus for efficient implantation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual knotting is used to secure sutures, then the suture can be locked, but the operation time is prolonged and requires high medical expertise

Engineering Contradiction:

Improvesuture locking reliabilityVSAvoidoperation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The suture locking device enables self-service by allowing the suture to lock itself through the squeezing part and cavity wall without requiring manual knotting by the doctor. The device automatically secures the suture when the driving component activates the squeezing mechanism, eliminating the need for high-level manual expertise and reducing operation time while maintaining reliable suture locking.

Inventive Principle:

Principle #25Self-service

2Reliability

If manual knotting is used to secure sutures, then the suture can be locked, but high technical skill is required

Engineering Contradiction:

Improvesuture locking reliabilityVSAvoidoperational difficulty

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device transforms a skill-intensive manual process into an automated self-service mechanism. The suture locking function is performed automatically by the device's squeezing part and cavity wall structure, eliminating the need for doctors to possess high-level knotting skills while ensuring consistent and reliable suture securing.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical knotting system with an automated mechanical squeezing system. Instead of requiring doctors to manually tie knots, the device uses a driving component to activate a squeezing mechanism that automatically secures the suture, simplifying the operational requirements while maintaining locking reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If manual knotting is used to secure sutures, then the suture can be locked, but the knotting efficiency is low

Engineering Contradiction:

Improvesuture locking reliabilityVSAvoidknotting efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The suture locking device enables self-service by allowing the suture to lock itself through the squeezing part and cavity wall without requiring manual knotting by the doctor. The device automatically secures the suture when the driving component activates the squeezing mechanism, eliminating the need for high-level manual expertise and reducing operation time while maintaining reliable suture locking.

Inventive Principle:

Principle #25Self-service
