Solution Overview

Problem

Current image-guided surgical devices for ENT procedures lack integrated irrigation and aspiration systems, leading to reduced accuracy and increased invasiveness, with separate systems causing delays and tissue irritation, and existing solutions are not suitable for minimally invasive osteotomies or non-operating theater settings.

Innovation Solution

A multifunctional osteotomy device combining shielding, cutting, cauterization, irrigation, and aspiration capabilities with integrated cameras and lighting, allowing simultaneous application of these functions while minimizing tissue injury and enabling direct visualization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate irrigation and aspiration systems are used in image-guided surgery, then irrigation and aspiration functions can be provided, but the systems cause delays in procedures and reduce sensor accuracy due to movement away from target sites

Engineering Contradiction:
Improveirrigation and aspiration functionVSAvoidprocedure delay
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent combines separate irrigation and aspiration systems into a single integrated catheter device. The catheter includes both an irrigation lumen and an aspiration lumen within one device, allowing simultaneous delivery of irrigation fluid and removal of debris/aspirate without requiring separate instruments. This integration eliminates the time losses associated with inserting and removing separate systems while maintaining sensor proximity to the target site throughout the procedure.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If separate irrigation and aspiration systems are used, then irrigation and aspiration can be performed, but sensors mounted on proximal portions of instruments are moved away from targeted surgery sites reducing accuracy

Engineering Contradiction:
Improveirrigation and aspiration functionVSAvoidsensor accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent combines separate irrigation and aspiration systems into a single integrated catheter device. The catheter includes both an irrigation lumen and an aspiration lumen within one device, allowing simultaneous delivery of irrigation fluid and removal of debris/aspirate without requiring separate instruments. This integration eliminates the time losses associated with inserting and removing separate systems while maintaining sensor proximity to the target site throughout the procedure.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If multiple separate devices are used for osteotomy procedures, then comprehensive surgical functions can be achieved, but device complexity and invasiveness increase

Engineering Contradiction:
Improvesurgical functionVSAvoidnumber of devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent describes a single catheter device that performs multiple surgical functions: cutting (via integrated cutting elements or guidewire), cauterization (via integrated electrosurgical elements), irrigation (via irrigation lumen), and aspiration (via aspiration lumen). This multi-functional design eliminates the need for multiple separate devices, reducing procedural complexity and invasiveness while providing comprehensive surgical capability through one integrated instrument.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Productivity

If traditional osteotomy devices are used, then bone cutting can be performed, but tissue protection near surgical target-sites is insufficient

Engineering Contradiction:
Improvebone cutting capabilityVSAvoidtissue injury
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent employs a protective shield or barrier element that acts as an intermediary between the cutting elements and surrounding healthy tissue. This shield is positioned adjacent to the surgical target site during bone cutting, selectively blocking harmful mechanical forces, heat, and debris from affecting nearby healthy structures while allowing the cutting elements to effectively remove targeted bone. The shield serves as a physical mediator that protects critical tissue during the bone cutting process.

Inventive Principle:
Principle #24Intermediary (Mediator)
