Device and method for recognizing microwave ablation needle

Abstract

The invention provides a device and a method for recognizing a microwave ablation needle; the microwave ablation needle comprises an ablation needle head, an ablation needle tube and a handle, wherein a tetrafluoroethylene insulator is arranged between the ablation needle head and one end of the ablation needle tube; the other end of the ablation needle tube is connected with the head of the handle; the ablation needle tube is internally provided with a microwave coaxial cable connected with the ablation needle head; the device for recognizing the microwave ablation needle comprises a memory and a controller, wherein the memory is arranged in the handle and is connected with the microwave coaxial cable; the model parameters of the microwave ablation needle are preset in the memory; and the controller is arranged in a microwave therapy apparatus and is connected with the memory by a cable. The method for recognizing the microwave ablation needle comprises the steps that the usage record of the microwave ablation needle is recorded by the memory, and the controller is used for reading and recognizing the information in the memory. The invention can be used for recognizing the microwave ablation needle in the using process, and distinguishing whether the microwave ablation needle is in accordance with the model or not.

Description

technical field [0001] The invention relates to an identification device of a microwave ablation needle and an identification method thereof, in particular to an identification device of a microwave ablation needle capable of identifying the number of times of use. 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, microwave ablation needles for tumors are recommended for one-time use. Some doctors or patients use one needle multiple...
