Solution Overview

Problem

Existing bone plate alignment systems lack precision in aligning and securing orthopedic bone plates for effective joint compression, particularly in complex fracture scenarios, leading to suboptimal surgical outcomes.

Innovation Solution

A bone plate alignment guide apparatus comprising a body with an arm, attachment, and alignment portions, along with a fixation insert and guide pin, allows for precise alignment and secure fixation of bone plates across joint spaces, using screws and temporary fixation pins to facilitate accurate bone plate positioning and compression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing bone plate alignment systems are used, then the surgical procedure can be completed, but precision in aligning and securing bone plates for joint compression is insufficient

Engineering Contradiction:
Improvealignment precisionVSAvoidjoint compression effectiveness
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The alignment guide apparatus serves as an intermediary tool between the surgeon and the bone plate, providing precise alignment references through its guide bores and attachment mechanisms. The guide apparatus mediates the alignment process by defining exact trajectories for screw insertion and ensuring proper positioning of the bone plate relative to the joint, thereby resolving the contradiction between measurement precision and compression effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The alignment guide apparatus is attached to the bone plate before the actual fixation procedure. This preliminary action allows the surgeon to establish precise alignment and verify the positioning of guide bores before inserting screws. The pre-attachment of the guide apparatus ensures that all subsequent actions (screw insertion, compression) are based on pre-established precise geometric references, improving both alignment precision and joint compression effectiveness.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If complex fracture scenarios are treated with existing systems, then all fractures can be addressed, but procedural accuracy deteriorates

Engineering Contradiction:
Improvefracture scenario coverageVSAvoidprocedural accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The alignment guide apparatus is designed as a modular system with separable components including the guide body, attachment mechanisms, and interchangeable guide inserts. This segmentation allows the system to be adapted to different fracture scenarios by changing or repositioning specific components while maintaining the core alignment functionality, thus preserving procedural accuracy across versatile applications.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The alignment guide apparatus incorporates multiple guide bores at various angles and positions, along with versatile attachment mechanisms that can accommodate different bone plate configurations. This multi-functionality enables the single apparatus to address complex fracture scenarios with varying anatomical requirements while maintaining high procedural accuracy through its standardized precision reference system.

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

3Ease of operation

If bone plates are secured without precise alignment guidance, then the procedure is simpler, but surgical outcomes are suboptimal

Engineering Contradiction:
Improveprocedure simplicityVSAvoidsurgical outcome quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The alignment guide apparatus is designed to be self-aligning through its attachment mechanisms that automatically reference the bone plate geometry. Once attached, the guide bores self-position to provide the correct insertion trajectories without requiring complex manual alignment by the surgeon. This self-service capability maintains ease of operation while ensuring reliable surgical outcomes through precise alignment.

Inventive Principle:
Principle #25Self-service
