Problem

Cryosurgical probes are vulnerable to damage during tissue ablation procedures that involve the generation of products of electrolysis, which can jeopardize both patient and user safety.

Innovation Solution

A cryosurgical instrument with a protective member coupled to its exterior surface, designed to isolate the probe from products of electrolysis, and a system that includes a cryosurgical probe, an electrode for generating electrolysis products, and a controller for independently controlling the cryosurgical and electrolysis treatments, along with sensors for monitoring pH and electric field strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cryosurgical probe is used for tissue ablation with electrolysis, then the treatment efficacy is improved, but the probe becomes vulnerable to damage from electrolysis products

Engineering Contradiction:
Improvetreatment efficacyVSAvoiddamage from electrolysis products
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A protective member is introduced as an intermediary component between the cryosurgical probe and the electrolysis process. This protective member shields the probe from direct contact with electrolysis products while allowing the probe to function effectively for tissue ablation, thus resolving the contradiction between treatment efficacy and probe protection

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a protective member is added to isolate the probe from electrolysis products, then probe safety is improved, but device complexity increases

Engineering Contradiction:
Improveprobe protectionVSAvoiddevice structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protective member is implemented as a thin film or coating that can be applied to the cryosurgical probe surface. This approach provides effective protection against electrolysis products while minimizing the increase in device complexity and maintaining the probe's functional characteristics

Inventive Principle:
Principle #30Flexible shells and thin films
