A probe for the location of cancer tissues and method for the location of cancer tissues

摘要

A probe for localization of neoplastic tissues, according to the invention consists of a capacitive sensor (1) included in a circuit of a detection unit (2), supplied from a high-frequency generator (3); an output of the detection unit (2) is connected through a high-frequency amplifier (4) and an amplitude detector (5) to a low-frequency amplifier (6). Also an adder (7) is a part of the probe; one input of the adder is connected to the output of the low-frequency amplifier (6), and the second input of the adder is connected to the output of a unit (8) where a reference signal is memorized. The output from the adder (7) is connected to a unit (10) containing an acoustic annuciator (15) and optical display (12), where a measurement result undergoes an imaging process. This invention applies also to a technique of localization of neoplastic tissues, and the essence of this technique consists in that after the tested tissue has been isolated from the measuring probe by a separating plate, a difference in electrical permittivity is measured between a reference material, which is preferably a healthy tissue, and a neoplastic tissue, at voltage frequency from 50 MHz to 500 MHz, preferably at 100 MHz. The invention can be applied in medicine, especially in intrasurgical diagnostics of neoplastic lesions of mammary glands
