Solution Overview

Problem

Current radio frequency ablation surgical devices require surgeons to divert attention from the procedure to adjust parameters, lacking a system for pre-operative adjustments that allow focus on the surgical steps during intervention, with limited assistance from virtual images for orientation.

Innovation Solution

A remote control system for radio frequency ablation devices featuring a graphical user interface that allows surgeons to navigate and adjust parameters such as temperature and power levels before and during the procedure, maintaining sterility and enabling focus on surgical steps through a virtual interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If surgeons directly control parameters through buttons on the RF power generator during surgery, then parameter adjustment is immediate and simple, but surgeon attention is diverted from the surgical procedure

Engineering Contradiction:
ImproveParameter adjustment accessibilityVSAvoidSurgeon attention time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system allows surgeons to pre-configure ablation parameters (temperature, power, duration) before the surgical procedure begins. These parameters are stored and automatically applied during the procedure, eliminating the need for real-time adjustment and keeping the surgeon focused on the surgical field.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A remote control interface acts as an intermediary between the surgeon and the RF power generator. This interface can be positioned away from the surgical site, allowing parameter control without requiring the surgeon to leave the operative field or divert attention from the procedure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple control buttons are placed on the RF power generator for parameter adjustment, then control functionality is comprehensive, but the interface complexity increases

Engineering Contradiction:
ImproveParameter control capabilityVSAvoidControl interface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control interface is segmented into separate functional modules: pre-operative parameter configuration, real-time monitoring, and emergency control. This segmentation allows comprehensive control functionality while organizing the interface in a structured, manageable way that reduces perceived complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The remote control system serves multiple functions: parameter presetting, real-time monitoring, adjustment, and emergency shutdown. By consolidating these diverse functions into a single unified interface, the system reduces the need for multiple separate control devices and simplifies the overall control architecture.

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

3Adaptability or versatility

If surgeons adjust parameters during the surgical procedure, then real-time adaptability is achieved, but the risk of contamination to the sterile field increases

Engineering Contradiction:
ImproveReal-time parameter adaptabilityVSAvoidSterile field contamination risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

A remote control interface positioned outside the sterile field acts as an intermediary, allowing surgeons to adjust parameters without physically entering or contaminating the sterile operative area. The interface transmits control signals electronically while maintaining physical separation from the surgical site.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The remote control system creates a duplicate interface that mirrors the functionality of the primary RF power generator controls. This copy allows full parameter adjustment capability to be accessed from a non-sterile location, eliminating the need for physical presence at the generator during surgery.

Inventive Principle:
Principle #26Copying
