Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as image 3 As shown in the schematic diagram of the three-dimensional structure of the microwave ablation needle of the present invention, from the appearance structure, the microwave ablation needle consists of an ablation needle head 1, an insulating medium 2, a water inlet pipe 5, a water outlet pipe 4, an ablation needle pipe 6, a handle 10, a positioning sleeve 11, and a scale line 17 compositions. The outer diameter of the ablation needle 1 is 1.4-4 mm, and the length is 3-41 mm. An insulating medium 2 is provided between the ablation needle 1 and the front end of the ablation needle tube 6 . The insulation medium 2 may be made of tetrafluoroethylene insulating material. The end of the ablation needle tube 6 penetrates into the head of the handle 10 . The positioning sleeve 11 is used for marking and limiting the ...

Abstract

The invention discloses a microwave ablation needle and a microwave ablation therapeutic apparatus thereof, and relates to a structure of the microwave ablation needle and the microwave ablation therapeutic apparatus using the microwave ablation needle. The microwave ablation needle mainly comprises an ablation needle, an ablation needle tube, a microwave coaxial cable, a capillary, a handle witha crank, a temperature sensor, a fixed frame, a high-frequency joint and a water cavity, wherein the fixed frame comprises the high-frequency joint, a water inlet joint, a water outlet joint and the temperature sensor and is connected with a terminal external socket; the high-frequency joint comprises a lock card reed; and the water cavity used for circulating cold water is arranged in the handle. The circulating water enters the capillary from the water inlet joint, then enters the water cavity from the ablation needle tube, and finally flows out from the water outlet joint. The microwave energy enters the microwave coaxial cable from the high-frequency joint, and radiates through the ablation needle. The microwave ablation needle, a microwave power source and a computer control unit form the microwave ablation therapeutic apparatus. The microwave ablation needle and the microwave ablation therapeutic apparatus are mainly used for treating tumor through microwave ablation.

Description

technical field [0001] The invention relates to a medical device, in particular to a structure of a microwave ablation needle and a microwave ablation treatment instrument containing the microwave ablation needle. Background technique [0002] Microwave ablation is a highly efficient, rapid, uniform heating, thorough thermal coagulation, easy to use and safe treatment method for tumor tissue. It has been widely used in clinic for many years. With the deepening of clinical practice, clinical requirements for microwave ablation needles (microwave radiation antenna) are also getting higher and higher. When using microwave ablation needles to insert tumor tissue for treatment, it is hoped that the microwave ablation needles will become thinner and thinner, so as to minimize the damage to blood vessels, nerves and other tissues on the puncture path; it is hoped that the microwave power carried by the microwave ablation needles As large as possible, the ablation area is as large ...
