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

The present inventive concept relates to an improved cryosurgical instrument that integrates advanced features for efficient and safe treatment, addressing the limitations of existing cryosurgery and electrolysis systems.

Background and Problem Solved

The original patent disclosed a cryosurgical instrument combining cryosurgery and electrolysis treatments. However, the existing design had limitations in terms of thermal management, real-time monitoring, and treatment parameter control. The new inventive concept addresses these limitations by introducing a thermal insulation layer, real-time monitoring using non-invasive medical imaging, and a temperature control system to ensure precise temperature maintenance.

Detailed Description of the Inventive Concept

The enhanced cryosurgical instrument comprises a cryosurgical probe, at least one electrode, and a thermal insulation layer surrounding the probe to reduce heat transfer during treatment. The instrument may also include a control unit regulating the delivery of the cryosurgical treatment and the generation of products of electrolysis. Additionally, the instrument can be equipped with a temperature control system to maintain a predetermined temperature range during the treatment. In another embodiment, the instrument may utilize non-invasive medical imaging to monitor the treatment in real-time, allowing for adjustments to treatment parameters based on feedback.

Novelty and Inventive Step

The new inventive concept introduces several novel features that distinguish it from the original patent. The thermal insulation layer, real-time monitoring using non-invasive medical imaging, and temperature control system provide significant improvements in terms of safety, efficiency, and precision. These advancements constitute an inventive step, as they overcome the limitations of the existing design and provide a more effective and reliable solution for cryosurgery and electrolysis treatments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include varying the material and design of the thermal insulation layer, using different types of non-invasive medical imaging, or integrating additional sensors to monitor treatment parameters. Variations may also include adapting the instrument for specific medical applications, such as dermatology or oncology.

Potential Commercial Applications and Market

The enhanced cryosurgical instrument has significant commercial potential in the medical device industry, particularly in the fields of cryosurgery and electrolysis. The improved safety, efficiency, and precision of the instrument make it an attractive solution for medical professionals and hospitals. The target market may include hospitals, clinics, and medical research institutions, with potential applications in various medical specialties.
