Embodiment 1

[0025] Such as figure 1 , 2 In the shown embodiment 1, the two-chamber urinary catheter 2 composed of the urination chamber 4 and the air guide chamber 5 is the main body of the electrode catheter. Firstly, one end of the electrode lead 6 of the stainless steel wire is directly wound 6 times closely to form the ring electrode 3, so that the electrode lead and the ring electrode are integrated. The junction of the electrode lead wire 6 and the ring electrode 3 is formed with a bending section 11 perpendicular to the electrode lead wire and having a height equal to the wall thickness of the urinary catheter, so as to keep the surface of the urinary catheter smooth. Simultaneously, a vertical pin 10 whose length is equivalent to the wall thickness of the urinary catheter is formed on the tail end of the ring electrode 3 .

[0026] Insert each electrode lead wire 6 wound with ring electrode 3 into the urination cavity 4 from the corresponding position of the urinary catheter by ...

Embodiment 2

[0029] Such as image 3 , 4 In the shown embodiment 2, the three-chamber urinary catheter 13 composed of the urination chamber 4 , the first air-guiding chamber 15 and the second air-guiding chamber 14 is the main body of the electrode catheter. Two groups of 2 pairs of annular electrodes 3 are still arranged on the surface of the three-chamber urinary catheter of the present embodiment on the surface of the corresponding parts above the double balloons. The manufacturing method of the ring electrode is the same as that of Embodiment 1. Taking the catheter guide head 1 as the standard, the first and third ring electrodes form a group, and each electrode lead wire 6 is inserted into the second air guiding cavity 14 from the corresponding position of the catheter by its end, and drawn out from its port. The second and fourth ring electrodes form a group, and each electrode lead wire 6 is inserted into the urination cavity 4 from the corresponding position of the urinary cathet...

Abstract

The invention relates to a manufacturing method of electrode catheter of electrochemical prostate therapeutic equipment. Wherein, (1) one end of electrode wire is directly coiled around the ring electrode; (2) the tail end of ring electrode has a vertical thrusting needle; (3) inserting the end of electrode wire which has coiled the ring electrode through the surface of relative position of catheter into the emiction cavity and at the same time using the ring electrodes to cover relative parts of catheter; (4) inserting the vertical thrusting needle into the tube wall of catheter; (5) one group of ring electrodes is sheathed on the tube; (6) each electrode wire outside the port of emiction cavity is sheathed with a sheath and welded on a pin; (7) packaging after checking and disinfecting. The inventive electrode catheter integrates the metallic ring electrode and the electrode wire for radically overcoming the hidden trouble that separation of metallic ring electrodes of present external arranged two groups of multiple metallic ring electrode catheters and the electrode wire. Said manufacturing method can simplify the manufacturing process of electrode catheter to reduce the cost.

Description

technical field [0001] The invention relates to a processing method of an electrode catheter arranged in an electrochemical prostate treatment instrument. Background technique [0002] The invention patent application with the application number of 98100200.5 discloses another electrode catheter structure, which is composed of a catheter and two sets of metal ring electrodes arranged on the surface of the catheter. The lead wires are clamped between the ring electrode and the urinary catheter, and the lead wires of each electrode are introduced into the urination cavity from the lead wire hole made by the urinary catheter and drawn out from the mouth of the urinary catheter. The externally placed two sets of metal ring-shaped electrode urinary catheters can make full use of the existing urinary catheters, and the structure is relatively simple. What's more important is that two sets of multiple pairs of annular electrodes of the electrode catheter have a large contact area ...
