Solution Overview

Problem

Existing surgical stapling devices are expensive to manufacture and difficult to remove from tissue without causing damage, due to their complex structure and design.

Innovation Solution

A surgical stapling device with pins connected to a first plate element via a thread, where each pin has a shaft with one end attached to the plate and the other end connected to the first plate element, allowing the device to disintegrate into two parts when the thread is severed for easy removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pins are permanently fixed to the plate element, then the clamping device is stable and reliable during use, but it becomes difficult to remove from tissue without causing damage

Engineering Contradiction:

Improvestability of clamping deviceVSAvoidremovability of clamping device

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The pin is divided into two separable parts: a shaft that remains in the plate element and a tip that can be detached. This segmentation allows the device to be stable during use (shaft anchored in plate) but easily removable (tip can be detached and pulled out without damage to tissue or plate).

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection between the pin and plate element is made dynamic rather than static. The thread connection allows the pin to be firmly held during application but easily released when the thread is severed, transforming the device from a permanent fixture to a removable component without tissue damage.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a complex structure with multiple connection elements is used, then the clamping device is stable and secure, but it becomes expensive to manufacture

Engineering Contradiction:

Improvestability of connectionVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The shaft and pin are merged into a single integrated component that can be manufactured as one piece. This eliminates the need for separate connection elements and reduces manufacturing complexity while maintaining the stability and security of the connection when assembled.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If pins are arranged parallel to each other with thread connection, then the device allows easy removal when thread is severed, but the structural complexity increases

Engineering Contradiction:

ImproveremovabilityVSAvoidstructural complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The pin structure is segmented into a shaft portion (integrated with plate) and a detachable tip portion. This segmentation enables easy removal when the thread is severed, as the tip can be pulled out independently without compromising the plate element or causing tissue damage.

Inventive Principle:

Principle #1Segmentation
