Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Medical procedures often require multiple tools with separate handles, increasing kit size and cost, and there is a need for a single, disposable, and sterile handle assembly that can accommodate multiple instruments.

Innovation Solution

A handle assembly with a locking mechanism and retaining member that allows for the secure attachment and detachment of medical tools, featuring a side passage with a biasing mechanism to retain the tool and a torque transmission system for efficient tool operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple tools with separate handles are used for medical procedures, then each tool can be optimized for its specific function, but the kit size and cost increase

Engineering Contradiction:

Improvetool functionalityVSAvoidkit size

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The handle assembly is designed with a universal interface that can accommodate multiple different medical instruments from the kit. The locking mechanism with side passage and retaining member can securely hold various instrument types (drills, drivers, extractors, etc.), allowing one handle to perform multiple functions that previously required separate handled tools

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple tools with separate handles are used, then each tool can be independently optimized, but the cost of the kit increases

Engineering Contradiction:

Improvetool functionalityVSAvoidkit cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The invention merges the handle function with multiple instrument capabilities into a single integrated assembly. By combining what were previously separate handled tools into one handle assembly that can accept multiple instruments, the total number of components is reduced, simplifying manufacturing and reducing overall kit cost

Inventive Principle:

Principle #5Merging (Combining)

3Quantity of substance

If a single handle assembly accommodates multiple instruments, then kit size and cost are reduced, but the locking mechanism must securely retain different tool types

Engineering Contradiction:

Improvekit sizeVSAvoidtool retention

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The locking mechanism incorporates a biasing member that automatically engages the locking ball with the instrument shaft upon insertion. The spring-loaded design provides automatic tool retention without requiring additional manual securing steps, ensuring reliable holding while accommodating various instrument types

Inventive Principle:

Principle #25Self-service

AI summary

A handle assembly includes an elongate body having a proximal end, a distal end, and a central longitudinal axis extending between the proximal end and the distal end. A side passage extends through the body transverse to the longitudinal axis and intersects the through-passage. A locking mechanism is located in the side passage and is configured to releasably retain a medical tool onto the assembly.
