Solution Overview

Problem

Existing surgical stapling and cutting instruments lack effective methods to ensure stable tissue compression and compatibility verification during the stapling process, leading to potential inconsistencies and suboptimal staple formation.

Innovation Solution

Incorporation of LEDs at the edges of the tissue-contacting surface of the staple cartridge, which emit ultraviolet or infrared light to indicate tissue stability and compatibility, along with a processor to compare tissue parameters against acceptable standards, and staples coated with fluorescing dye for enhanced visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If LEDs are added to indicate tissue stability and compatibility, then the reliability of tissue compression monitoring is improved, but the device complexity increases

Engineering Contradiction:
Improvetissue compression stabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses LEDs that emit different colors (red, yellow, green) to indicate different tissue stability states. This visual feedback system allows surgeons to quickly assess tissue compression stability without complex instrumentation, resolving the contradiction by providing reliable monitoring through simple color-coded indicators.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent replaces complex mechanical monitoring systems with optical indicators (LEDs). Instead of using mechanical sensors and complex signal processing to monitor tissue stability, the system uses LEDs to provide direct visual feedback, thereby improving reliability while reducing device complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If multiple LEDs are used to indicate different tissue parameters, then the measurement precision is improved, but the device complexity increases

Engineering Contradiction:
Improvetissue parameter monitoringVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Different colored LEDs (red, yellow, green) represent different tissue parameter states, providing precise measurement information through simple color codes. This allows multiple parameters to be monitored simultaneously with minimal complexity by encoding information in the color domain rather than requiring multiple separate indicators.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The LED indicator system serves multiple functions: it monitors tissue stability, indicates compatibility, and provides visual feedback on compression quality. By making the LED system multi-functional, the patent achieves precise measurement of multiple parameters without proportionally increasing device complexity.

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

3Manufacturing precision

If fluorescing dye is applied to staples, then the visibility and manufacturing precision of staple formation is improved, but the loss of substance increases

Engineering Contradiction:
Improvestaple formationVSAvoidfluorescing dye
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The fluorescing dye on staples provides visual contrast to assess staple formation quality and positioning. The dye allows surgeons to see staple deployment clearly, improving manufacturing precision of the stapling process. The minimal amount of dye used represents an acceptable trade-off for the significant improvement in staple formation visibility and precision.

Inventive Principle:
Principle #32Color changes
