This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,240.

Summary of the Inventive Concept

An improved cryosurgical instrument that combines cryosurgery and electrolysis treatments with advanced thermal energy harvesting and real-time monitoring capabilities, enhancing treatment outcomes and efficiency.

Background and Problem Solved

The original patent disclosed a cryosurgical instrument that combined cryosurgery and electrolysis treatments, but it had limitations in terms of thermal energy loss, treatment monitoring, and electrode configuration. The new inventive concept addresses these limitations by introducing a thermally insulated shaft, non-invasive real-time monitoring, and a detachable protective member with thermal energy harvesting capabilities.

Detailed Description of the Inventive Concept

The enhanced cryosurgical instrument comprises a cryosurgical probe with a thermally insulated shaft to minimize thermal energy loss during cryosurgical treatment. The instrument also features at least one electrode configured to generate products of electrolysis at the target tissue, and a protective member coupled to at least a portion of the exterior surface of the cryosurgical probe. The protective member is detachable and equipped with a thermal energy harvesting system, which converts excess thermal energy into electrical energy. The instrument can be used in conjunction with non-invasive medical imaging for real-time treatment monitoring and optimization using machine learning algorithms.

Novelty and Inventive Step

The new inventive concept introduces several novel features, including the thermally insulated shaft, detachable protective member with thermal energy harvesting, and real-time monitoring capabilities using non-invasive medical imaging. These features provide a significant improvement over the original patent, enabling more efficient and effective cryosurgery and electrolysis treatments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the design of the thermal energy harvesting system, using different types of electrodes or cryosurgical probes, or integrating the instrument with other medical imaging modalities. Additionally, the concept could be adapted for use in other medical treatments or industries, such as cosmetic or veterinary applications.

Potential Commercial Applications and Market

The enhanced cryosurgical instrument has significant commercial potential in the medical device industry, particularly in the fields of oncology, dermatology, and cardiology. The instrument's ability to provide more efficient and effective treatments, combined with its real-time monitoring capabilities, could lead to increased adoption and market share.
