    • An arrangement for determining the position of a needle in an organ system and a method utilizing the arrangement in cosmetic treatment or cosmetic surgery. The arrangement (1) comprises a needle (2) with a distal tip (3), a measurement circuit (4) measuring the bioimpedance of tissues, a detection means (10) connected to the measurement circuit measuring bioimpedance and arranged to detect the progress of the distal tip (3) of the needle at a real-time basis from the bioimpedance measured from tissues. The arrangement (1) comprises at least two electrodes (16, 18, 21, 22) arranged at the distal tip (3) of the needle and connected to the measurement circuit (4). All the electrodes (16, 18, 21, 22) measuring impedance and needed for monitoring the progress of the distal tip (3) of the needle are arranged to the distal tip (3) of the needle.
    • 用于确定针在器官系统中的位置的装置以及在美容治疗或整容手术中利用该装置的方法。 布置(1)包括具有远端尖端(3)的针(2),测量组织的生物阻抗的测量电路(4),连接到测量生物阻抗的测量电路的检测装置(10),并且被布置成检测进度 根据从组织测量的生物阻抗实时地实现针的远端(3)。 布置(1)包括布置在针的远端(3)处并连接到测量电路(4)的至少两个电极(16,18,21,22)。 测量阻抗的所有电极(16,18,21,22)被布置到针的远端(3)上,用于监测针的远端尖端(3)的进展。
