AI Technical Summary

Technical Problem

The existing bipolar water-cooled ablation electrode structure causes heat to be conducted to normal tissue during the ablation process, resulting in an excessively long recovery period and affecting the patient's recovery efficiency.

Method used

A bipolar water-cooled ablation electrode structure was designed, comprising a heat insulation sleeve, a flexible sleeve, a support tube, and a cooling system. The heat insulation sleeve provides physical isolation, and the coolant provides cooling, blocking heat conduction. The support tube and a cutting blade are used to remove necrotic tissue, ensuring that the ablation area covers the tumor tissue and avoiding damage to normal tissue.

Benefits of technology

It effectively prevents heat from being conducted to normal tissue, ensuring that the ablation area completely covers the tumor tissue, reducing accidental damage to surrounding tissues, and shortening the patient's recovery period.

Abstract

This invention discloses a bipolar water-cooled ablation electrode structure, relating to the field of ablation needle technology. It includes a handle and a connector slidably connected to the end of the handle, a needle body fixedly connected to the end of the connector, a heat insulation sleeve slidably connected to the outer periphery of the needle body, and a flexible sleeve fixedly connected to the bottom of the heat insulation sleeve. The inner wall of the flexible sleeve is fitted to the outer wall of the bottom end of the needle body. This invention, by providing a slidable heat insulation sleeve on the outer periphery of the needle body, moves the heat insulation sleeve to the edge of the tumor tissue before ablation. Utilizing the physical isolation of the heat insulation sleeve and the cooling of the coolant, it effectively prevents the heat generated during ablation from being conducted to normal tissue. Through the cooperation of the support tube, support rod, and positioning rod in the package, the bottom of the flexible sleeve automatically expands to form an flared shape when the heat insulation sleeve moves, completely covering tumor tissues of different shapes and sizes, ensuring that the ablation area completely covers the tumor while avoiding accidental damage to surrounding normal tissues.
