Prostate gland tissue treatment probe by electric liquefaction

Abstract

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.

Description

technical field [0001] The invention relates to an electrolytic treatment probe, in particular to an electrolytic treatment probe for prostate tissue. It is the first choice of treatment probe for the treatment of benign prostatic hyperplasia by electrolytic treatment apparatus in various medical institutions. Background technique [0002] Prostatic hyperplasia is a common disease in elderly men, and it is a disease with progressive dysuria as the main clinical symptom. In the early stage, frequent urination, urgency, nocturia and other stimulating symptoms were the main symptoms. After the development of bladder outlet obstruction, the clinical manifestations are symptoms such as waiting for the beginning of urination, thinning of urine stream, interruption of urine stream, lingering after urination, and a feeling of incomplete urination. When the bladder detrusor loses its compensatory capacity, life-threatening serious complications such as overflow incontinence, hydron...

AI Technical Summary

Problems solved by technology

Nevertheless, through nearly a hundred cases of in vivo and in vitro pathological examinations, it is found that the prostate electrolysis probe still has the following unsatisfactory defects, which need to be improved: 1. The radial treatment range of liquefied tissue is small, with a maximum radius of 10mm, For patients with large benign prostatic hyperplasia, obstruction will often occur again within two years after being cured; 2. In the later stage of the treatment process, due to more tissue debris falling off, the drainage tube is prone to blockage, and at this time the positive electrode in the tube is surrounded by The gas film is contained, and the treatment current is often interrupted; 3. The inner electrode of the anode is made of expensive platinum-rhodium alloy wire, and repeated use must be strictly sterilized, otherwise there will be hidden dangers of cross-infection
