Osteotomy Burr and Blade Layout for Single-Pass Wedge Cuts

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional surgical cutting instruments require multiple cuts and passes to achieve a desired osteotomy shape, leading to inconsistencies and inefficiencies in osteotomy procedures.

Innovation Solution

Surgical instruments featuring cutting burrs on one or both surfaces, combined with cutting blades, allow for a single pass to perform a wedge-shaped osteotomy, enhancing precision and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional surgical cutting instruments are used to perform osteotomy, then multiple cuts and passes are required to achieve the desired shape, but this results in inconsistencies in shape and size of the resulting osteotomy and increases procedure time

Engineering Contradiction:

Improveosteotomy shape consistencyVSAvoidprocedure time

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The cutting instrument is divided into multiple cutting elements (burrs and blades) positioned at different locations and orientations on the same instrument body, allowing simultaneous engagement with the bone to create multiple cuts in a single pass

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple cutting functions (multiple cuts and passes) are merged into a single instrument that can perform all necessary cutting actions in one pass, eliminating the need for multiple sequential operations and ensuring consistent osteotomy shape and size

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If traditional surgical instruments perform multiple cuts to achieve desired osteotomy, then thorough cutting is achieved, but the procedure becomes time-consuming and inconsistent

Engineering Contradiction:

Improveosteotomy accuracyVSAvoidprocedure time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The instrument is pre-configured with multiple cutting elements positioned to perform all necessary cuts simultaneously during a single pass, eliminating the need for multiple sequential operations and ensuring accurate, consistent osteotomy results

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cutting action is made continuous through a single-pass design where multiple cutting elements work simultaneously along the bone, maintaining constant cutting engagement without interruption or repetition, thereby reducing procedure time while ensuring thorough and accurate osteotomy

Inventive Principle:

Principle #20Continuity of useful action
