Solution Overview

Problem

Existing bone plates are not easily usable and lack reliable attachment methods to bones, which can complicate the healing process of damaged or fragmented bones.

Innovation Solution

A bone plate with elongated guiding channels and a cap member that allows for flexible elongated members to be securely positioned and fixed, combined with a porous plate member for enhanced bone integration and a separation tool for easy removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional fixation techniques (screws, circumferential wires) are used to attach bone plates, then the bone plate can be secured to the bone, but the attachment process becomes complicated and difficult to use

Engineering Contradiction:

Improveattachment reliabilityVSAvoidease of use

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces circumferential wires as intermediary elements that wrap around the bone and pass through positioning inserts of the bone plate to secure it. This mediator approach simplifies the attachment process compared to direct screw fixation, as the wires can be easily threaded and tightened to reliably secure the bone plate to the bone.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The bone plate is pre-configured with positioning inserts and guiding channels before surgery. These preliminary structural preparations allow the circumferential wires to be easily routed and positioned during the surgical procedure, reducing the complexity of the attachment process and improving ease of operation while maintaining reliable fixation.

Inventive Principle:

Principle #10Preliminary action

2Device complexity

If the bone plate is designed with fixed positioning inserts, then the structure is simple, but the adaptability to different bone configurations is limited

Engineering Contradiction:

Improvestructural simplicityVSAvoidadaptability to bone configuration

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The bone plate incorporates guiding channels that allow circumferential wires to be dynamically positioned and routed along different paths. This dynamic wire routing capability enables the same bone plate structure to adapt to various bone configurations and anatomical variations, increasing versatility without complicating the plate's basic structure.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The positioning inserts are designed as separate, modular components that can be independently positioned within the guiding channels. This segmentation allows the wire fixation system to be adapted to different bone shapes and sizes by adjusting the position of individual inserts, maintaining structural simplicity while enhancing adaptability.

Inventive Principle:

Principle #1Segmentation

AI summary

A bone plate has bone facing side, a front side being arranged substantially opposite to and facing away from the bone facing side, and at least a first and a second elongated guiding channel. The first and second guiding channels are configured to receive a flexible elongated member such as, for example, a cerclage wire, and the first and second guiding channel are each further configured to guide the elongated member along a respective first and second guiding channel axis (A, B) from a first to a second lateral region of the bone plate. The first and second guiding channel axes (A, B) cross each other in at least one region of the bone plate outer front side.
