Segmented Surgical Stapler Fastener with Rotating Second Segment

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing surgical stapling devices simultaneously expose and fasten both segments of a fastener, limiting independent exposure and positioning of each segment, which restricts precise tissue manipulation and flexibility in fastening angles and paths.

Innovation Solution

A device with a first segment, a second segment, and a connection portion, featuring a moving mechanism to rotate the second segment to match the angle of the first segment, allowing independent exposure and positioning, and a holding mechanism for releasable attachment, enabling flexible segment movement and angle adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If both segments of the fastener are simultaneously exposed and fasten tissue, then the fastening process is simplified and completed in one action, but independent exposure and positioning of each segment is lost, limiting tissue manipulation flexibility

Engineering Contradiction:

Improvefastening process efficiencyVSAvoidindependent segment positioning capability

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The fastener is divided into two independent segments that can be exposed and positioned separately. The first segment is exposed through a first opening while the second segment is exposed through a second opening, allowing each segment to be independently manipulated and positioned before fastening the tissue together.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If a single fastening action is used for both segments, then the device structure is simplified, but the ability to accommodate various fastener angles and paths is reduced

Engineering Contradiction:

Improvedevice structure simplicityVSAvoidfastener angle and path flexibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The device incorporates movable components including a rotatable first segment and a movable second segment, along with a movable connector that can change its configuration. This dynamic structure allows the fastener to accommodate various angles and paths while maintaining a relatively simple overall device design.

Inventive Principle:

Principle #15Dynamics

3Measurement precision

If the first segment is used as a guide for correct fastener positioning, then positioning accuracy is improved, but the device must allow sequential exposure rather than simultaneous exposure

Engineering Contradiction:

Improvefastener positioning accuracyVSAvoidfastening process speed

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The first segment is exposed and positioned in advance before the second segment. This preliminary action allows the first segment to serve as a guide for correct positioning, ensuring accurate alignment before the second segment is exposed and fastening is completed.

Inventive Principle:

Principle #10Preliminary action
