Microwave ablation needle and connection method thereof

Abstract

The invention provides a microwave ablation needle and a connection method thereof. The microwave ablation needle comprises an ablation needle head, an ablation needle tubing and a handle, wherein a polytetrafluoroethylene insulator is arranged between the ablation needle head and one end of the ablation needle tubing; the other end of the ablation needle tubing is connected with the head of the handle; the handle comprises a main body and a base; the tail of the main body is provided with an insertion hole inserted into the base and a coaxial cable connector; the upper surface of the main body is a first plane and the lower surface of the main body is a first cambered surface; the base is provided with a metal interface; the upper surface of the base is a second plane and one side of the base is a second cambered surface; and when the main body is inserted into the base, the first plane and first cambered surface of the main body respectively correspond to the second plane and second cambered surface of the base, and the coaxial cable connector is fastened with the metal interface. The method comprises the following steps: ensuring the first plane and first cambered surface of the main body to respectively correspond to the second plane and second cambered surface of the base; and inserting the insertion hole of the main body into the base and fastening the coaxial cable connector with the metal interface. The microwave ablation needle can be convenient to connect and remove.

Description

technical field [0001] The invention relates to a microwave ablation needle and a connection method thereof, in particular to a microwave ablation needle which can be easily connected and disassembled. Background technique [0002] With the development of medical imaging technology, under the guidance of images, microwave ablation of tumors has become a new method of tumor treatment. Under the guidance of B-ultrasound or CT images, microwave treatment needles are inserted into human tumor tissues to treat tumors. Perform thermal ablation therapy. Because microwave ablation therapy is a treatment method with high efficiency, rapidity, uniform heating, thorough thermal coagulation, convenient use and safety for tumor tissue, it has been widely used in clinic for many years. [0003] At present, most of the existing tumor microwave ablation needles and microwave cables on the market are connected in one piece and cannot be disassembled. It is cumbersome and inconvenient during...
