MICROWAVE FIELD-DETECTING NEEDLE ASSEMBLY, AND METHOD OF MANUFACTURING THE SAME, METHOD OF ADJUSTING ABLATION FIELD RADIATING INTO TISSUE USING THE SAME, AND SYSTEM INCLUDING THE SAME
PROBLEM TO BE SOLVED: To treat tumors with microwaves at a temperature lower than a temperature causing destruction of adjacent healthy cells.SOLUTION: A microwave field-detecting needle assembly 100 comprises a needle assembly 110. The needle assembly 110 includes a distal portion 130, a proximal portion 160, and a junction member 150 disposed between the distal portion 130 and the proximal portion 160. The junction member 150 includes a recess defined therein. The needle assembly 110 also includes a rectifier element disposed in the recess. The rectifier element includes a first terminal electrically coupled to the distal portion 130, and a second terminal electrically coupled to the proximal portion 160.SELECTED DRAWING: Figure 1【課題】マイクロ波による腫瘍の治療においては、隣接する健康な細胞を破壊する温度よりも低い温度で行う必要がある。【解決手段】マイクロ波場検出ニードルアセンブリ１００はニードルアセンブリ１１０を含む。ニードルアセンブリ１１０は、遠位部分１３０と、近位部分１６０と、遠位部分１３０と近位部分１６０との間に配置された接合部材１５０とを含む。接合部材１５０はその中に画定された凹部を含む。ニードルアセンブリ１１０は、凹部内に配置された整流素子も含む。整流素子は、遠位部分に１３０電気的に接続された第１の端子と、近位部分１６０に電気的に接続された第２の端子とを含む。【選択図】図１
