Microwave ablation needle for treating thyroid tumors

Abstract

The invention discloses a microwave ablation needle for treating thyroid tumors and belongs to microwave ablation needles. The microwave ablation needle comprises a needle body. A handle is mounted at the tail end of the needle body. A puncture head is disposed at the front end of the needle body. A radiator is mounted at the rear end of the puncture head. A radiation window wraps the radiator. A focusing reflecting ring is disposed at the rear end of the radiation window and in contact with the end of the needle body. A coaxial cable is further disposed inside the needle body. The radiator is connected into a radio frequency coaxial connector through the coaxial cable. Due to the fact that the radiation window wraps the radiator and is connected with the focusing reflecting ring, a focusing reflecting structure is formed at the tip of the ablation needle, the microwaves emitted by the radiator gather at the front end of the tip of the ablation needle and do not reflect backwards, effectiveness of the microwaves is increased effectively, and tumor ablation standing wave ratio can be realized with a relative-short needle tip during actual application. In addition, the needle body is lightweight, tumor ablation flexibility is increased, and the ablation needle is suitable for being operated by a single person.

Description

technical field [0001] The invention relates to a microwave ablation needle, more specifically, the invention mainly relates to a microwave ablation needle used for treating thyroid tumors. Background technique [0002] With the advancement of tumor treatment science, considerable progress has been made in clinical microwave ablation of tumors in recent years. Microwave ablation is the use of microwave energy to act on the tissue to immediately produce a thermal effect. Within a few minutes, a stable spherical heat field is formed. The center temperature is greater than 100°C and the edge is greater than 60°C. The tumor tissue is instantly coagulated and inactivated at high temperature, and then Gradually ablate to achieve the therapeutic purpose. Due to its high safety, small trauma and controllable effect on tissue, microwave ablation technology is more and more respected by doctors, and it will become the first choice of tumor ablation technology in the future. Due to...
