Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods for bone collection during osteotomies are inefficient and often result in bone fragments being left at the surgery site or requiring additional procedures for autografts, which can be painful and risky, while allografts and artificial materials pose contamination and antigenic risks.

Innovation Solution

The development of longitudinally extendable/retractable spirally wound, conically-shaped bone matter collection devices that can be attached to and detached from bone drills, allowing for efficient collection of bone chips during drilling, which can be used for bone grafting and are adaptable to various drilling instruments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional bone collection methods are used during osteotomies, then bone fragments are removed or left at the surgery site, but additional surgical procedures are required for autografts which increases pain and risk

Engineering Contradiction:

Improvesafety of bone grafting procedureVSAvoidnumber of surgical procedures required

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The invention combines the bone drilling operation with bone fragment collection into a single integrated process. The collection device is attached to the bone drill, allowing bone fragments to be captured during the drilling operation itself, eliminating the need for separate bone harvesting procedures and reducing the total number of surgical interventions required

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The collection device is positioned and ready to capture bone fragments before the drilling operation begins. The device is pre-attached to the drill with the collection chamber in place, so that as soon as drilling starts and bone fragments are generated, they are immediately captured rather than lost or left at the site

Inventive Principle:

Principle #10Preliminary action

2Productivity

If bone collection device is attached to bone drill, then bone chips can be collected during drilling, but the device structure becomes more complex

Engineering Contradiction:

Improveefficiency of bone chip collectionVSAvoidstructure of collection apparatus

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The collection device is divided into distinct functional segments: a collection chamber for capturing bone fragments, a spirally-wrapped ribbon member for containing the chips, and attachment interfaces for coupling to the drill. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The use of a spirally-wrapped ribbon member creates a flexible, collapsible collection chamber that can be contained within a compact structure. This flexible design allows the collection device to maintain a small profile when not in use while providing sufficient capacity during operation, reducing overall device complexity

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of operation

If collection device is made compact, then interference with drilling process is minimized, but collection capacity is reduced

Engineering Contradiction:

Improveinterference with drilling processVSAvoidvolume of bone chips collected

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The collection device incorporates dynamic elements that allow it to change its configuration during operation. The spirally-wrapped ribbon member can expand to maximize collection capacity when bone fragments are being generated, then contract to a compact form when not in use or during removal, allowing the device to adapt its volume to operational needs without constant interference

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The collection chamber is designed to nest within the drill assembly when not in use or during the drilling operation. The compact nested configuration minimizes interference with the drilling process, while the chamber can be expanded or accessed after drilling to retrieve the collected bone chips

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

This document describes bone matter collection devices and methods for their use. For example, longitudinally extendable/retractable spirally wound, conically-shaped bone matter collection/harvesting devices are described. In some implementations, such bone matter collection devices can be attachable with and detachable from bone drill bits. In some implementations, bone chips generated by bone drilling are collected in such a bone matter collection device while the bone matter collection device is detachably coupled to the bone drill bit, and the collected bone chips can be used for bone grafting and other purposes.
