Problems solved by technology

[0003] Most of the existing microwave therapy probes are single, and do not have the function of enhancing the liquid medium in the tissue. The range of treatment is limited and cannot meet the needs of most clinical cases, which affects the treatment effect and limits its application. At the same time, it only has a single heating function

Embodiment Construction

[0026] Such as figure 1 , figure 2 and Figure 4 As shown, the working part of the present invention is composed of two or more liquid medium-enhanced hollow cooling microwave probes 2, which are fixed on the operating handle 3, and the operating handle is connected with a microwave transmission line 6. The liquid medium-enhanced hollow cooling microwave probe includes a sleeve 13 connected to the operating handle, a microwave emission window 12 arranged at the top of the sleeve, a microwave emitting antenna 14 arranged in the sleeve and connected to the operating handle, a refrigerant input pipe 16 and Refrigerant output pipe 17. Each refrigerant input pipe 16 and refrigerant output pipe 17 are connected to the heat exchange device and the liquid circulation driving device through the refrigerant output port 4 and the refrigerant input port 5 on the operating handle to form a refrigerant cycle. The circulating refrigerant is used to cool the treatment probe itself, reduce...

Abstract

The invention discloses a multifunctional cold-circulating bundling microwave treatment probe comprising an operating handle and a bundle, wherein the bundle consists of two ore more than two liquid medium strengthened hollow cooling microwave probes; the center of the bundle is provided with a multifunctional passage used for infusing a liquid medium or embedding a solid medium into a target tissue or carrying out temperature measurement or tissue biopsy; and the multifunctional passage and the bundle are fixed on the operating handle. The invention can outstandingly enlarge the melting volume of a microwave tissue and has a function of enhancing the treatment effect by infusing the liquid medium or embedding the solid medium into the target tissue and multiple functions, i.e. the biopsy, the temperature measurement, and the like.

Description

technical field [0001] The invention relates to a medical device for ablation of human tissue, in particular to a multi-functional cold cycle cluster microwave therapy probe for thermal ablation of human solid tumor or diseased tissue. Background technique [0002] Microwave in situ ablation of solid tumors is a new method of minimally invasive treatment, and it is more and more widely used clinically. Microwave therapy probe is the key technology in this field. The microwave source is released into the tissue through the probe, causing the oscillation and friction of water molecules, generating heat, causing the temperature of the tissue to rise, making it solidified and necrotic, and damaging the diseased tissue, so as to achieve the purpose of treatment. [0003] Most of the existing microwave therapy probes are single, and do not have the function of enhancing the liquid medium in the tissue. The range of treatment is limited and cannot meet the needs of most clinical ca...
