The invention relates to an electrohydraulic
prostate tissue treatment probe, which comprises a probe
pipe body, wherein a drainage channel, a water-injection channel, a gas-injection channel and a
cathode channel are arranged in the probe
pipe body along the axial direction; the front end of the probe
pipe body is a guiding head; a positioning
balloon is arranged behind the guiding head; an external
cathode electrode is tightly wound on the probe pipe body on the rear side of the positioning
balloon; a leading-out end is connected with a
cathode plug through the cathode channel; an external
anode electrode is arranged between the positioning
balloon and the
cathode electrode, is wound by one circle at least, and is kept in a certain interval from the
cathode electrode; and the leading-out end is connected with an
anode plug through the drainage channel. The probe has the advantages that the probe is large in treatment range, safe, reliable, free from damage to non-target organs, insusceptible to cause relapse and insusceptible to produce fibrous plaque
hyperplasia and cicatricial
stenosis, reduces cost, can effectively eliminate the hidden trouble of
cross infection, enables patients to have good tolerance and slight adverse reaction, and is particularly suitable to treat elderly high-risk patients who suffer from prostatic
hyperplasia and cannot tolerate operations and
anesthesia.
