Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing surgical staple bending devices are used, then the staple configuration transition can be achieved, but the process is inefficient and time-consuming

Engineering Contradiction:

Improvebending efficiencyVSAvoidtime for configuration transition

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The surgical staple is pre-formed with inwardly angled arms that will automatically transition to a parallel configuration when deployed, eliminating the need for post-insertion bending operations and significantly reducing procedural time

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual mechanical bending operations with a self-actuating mechanism that uses the staple's own deployment forces to achieve the configuration transition, eliminating the need for separate bending tools and steps

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If manual bending operations are performed, then staple configuration can be changed, but surgical precision is reduced

Engineering Contradiction:

Improveconfiguration accuracyVSAvoidsurgical complexity

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The surgical staple system is designed to automatically achieve the desired parallel configuration through its own deployment mechanism, eliminating the need for surgeon-performed manual bending operations and ensuring consistent precision

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The staple is pre-engineered with specific geometric properties and material characteristics that ensure automatic transition to the correct configuration, removing variability introduced by manual operations

Inventive Principle:

Principle #10Preliminary action

AI summary

Medical device bending devices and methods of use are disclosed herein. An embodiment includes a body, a handle in rotatable relationship with the body, and a head that is coupled with the handle in such a way that when the handle is rotated the head is drawn at least partially into the body and towards the handle. A terminal end of the body that is opposite of the handle and the head cooperate as a vise that bends opposing arms of a surgical staple from an inwardly angled configuration to a parallel configuration (or at angles therebetween) when a crown of the surgical staple is clamped in the vise.
