Solution Overview

Problem

Existing medical devices for suturing internal organs to the body surface require simultaneous manipulation of two puncture needles, necessitating pre-determined piercing positions, which complicates the piercing operation and lacks operativity.

Innovation Solution

A medical device with a first unit and a second unit that are separately formed to be engageable and disengageable, featuring a first puncture needle and a second puncture needle with a holding plate system that allows for independent positioning and storage of the needles, enabling easier adjustment and storage of the second needle after piercing the first.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If two puncture needles are manipulated simultaneously in a fixed configuration, then the device structure is simple, but the operativity of the piercing operation deteriorates due to inability to adjust piercing positions

Engineering Contradiction:

Improveoperativity of piercing operationVSAvoiddevice structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The device is divided into two separate units: a first unit with a first puncture needle and a second unit with a second puncture needle. Each unit can be independently manipulated and positioned, allowing flexible adjustment of piercing positions without requiring simultaneous manipulation of fixed needles. The units can be engaged or separated as needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The holding plate of the second unit is designed to be movable relative to the first unit, enabling dynamic adjustment of the second puncture needle's position and orientation. This allows the operator to optimize piercing positions and angles during the procedure, improving operativity while maintaining a relatively simple overall device structure.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If piercing positions are predetermined for two needles, then the device structure is simple, but the adaptability to different piercing requirements deteriorates

Engineering Contradiction:

Improveadjustability of piercing positionsVSAvoiddevice structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By separating the two puncture needles into independent units with separate holding plates, the device allows each needle to be positioned independently according to specific surgical requirements. This segmentation enables adaptability to different piercing positions and angles without complicating the overall device structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The holding plate of the second unit can be pre-positioned or adjusted before the piercing operation to optimize the second puncture needle's position. This preliminary adjustment capability allows the operator to prepare optimal piercing configurations in advance for each specific case.

Inventive Principle:
