Solution Overview

Problem

Conventional techniques for harvesting autologous bone tissue during spinal fusion surgeries often result in significant waste due to inadequate preservation and separation of bone tissue from other materials.

Innovation Solution

A bone tissue collection device comprising a sterile exterior collection container and a sterile interior filter container with pores, along with suction inlet and outlet tubes, is designed to collect and filter autologous bone tissue efficiently, allowing for the separation of bone tissue from blood and irrigation fluids.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If conventional techniques are used to harvest bone tissue, then the surgical procedure can be completed, but significant bone tissue is wasted due to inadequate preservation and separation

Engineering Contradiction:

Improvebone tissue wasteVSAvoidcollection and separation process

Core Design Contradiction:

Loss of substanceVSEase of manufacture

Solution Approach 1:

The device segments the collection process into distinct functional zones: an exterior collection container for receiving bone-blood-irrigation mixture, an interior filter container with pores for separating bone tissue from fluids, and separate outlet paths for bone tissue and waste fluids. This segmentation enables simultaneous collection and separation, preventing bone tissue waste while maintaining procedural efficiency

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The filter container acts as an intermediary component between the collection container and the final bone tissue product. It mediates the separation process by allowing blood and irrigation fluids to pass through its pores while retaining bone tissue particles, thus preserving bone tissue without requiring complex manual separation procedures

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If bone tissue is collected and filtered during surgery, then bone tissue preservation is improved, but the device complexity increases

Engineering Contradiction:

Improvebone tissue preservationVSAvoidcollection device structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device employs a nested structure where the interior filter container is placed inside the exterior collection container. This nesting approach integrates multiple functions (collection, filtration, separation) into a single compact unit, improving bone tissue preservation reliability while minimizing the increase in overall device complexity and footprint in the surgical field

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The collection device is designed as a multi-functional unit that simultaneously performs bone tissue collection, blood-irrigation separation, and bone tissue filtration. This universal design improves preservation reliability by ensuring all critical functions are integrated into one device, rather than requiring multiple separate instruments that would increase overall complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Quantity of substance

If all available bone tissue is collected and preserved, then the quality of autograft material is improved, but the time required for collection and separation increases

Engineering Contradiction:

Improvebone tissue collectionVSAvoidcollection and separation time

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The device enables continuous collection and separation of bone tissue throughout the surgical procedure. The suction source continuously draws bone-blood-irrigation mixture through the filter container, which continuously separates bone tissue from fluids. This continuous operation maximizes bone tissue collection quantity without requiring interruption for manual separation, thus avoiding time loss

Inventive Principle:

Principle #20Continuity of useful action
