Abstract:
1. A diagnostic cylindrical probe introduced through the body to detect the mechanical resistance of the tissue to piercing, comprising a cylindrical probe body a compressible pointed piercing tip having a base mounted at a distal end of the cylindrical probe body through a coiled wire sliding over the surface of an inbuilt changeable electrical resistance and over a metal blade, a first wire connecting the metal blade to an electrical source, the first wire passing through the body of the probe; a second wire connecting the electrical resistance to the electrical source, the second wire passing through the body of the probe; wherein the electrical source is located outside the probe; and a monitor comprising an Ammeter or Voltmeter to detect the electrical current intensity or voltage with the ability to add a registering unit using sensitive paper to monitor and record the electrical resistance, wherein the nature of the target tissue is detected by changing the mechanical resistance faced by the tip of the probe during its passage in the target tissues into a change in the electrical resistance.
