Embodiment Construction

[0013] Further illustrate the present invention below in conjunction with embodiment and accompanying drawing.

[0014] Such as figure 1 2. In the embodiment shown in 2, the main body of the urinary catheter 1 made of silica gel or rubber is composed of an air guide chamber 9 and a urination chamber 8, and the linear electrode 2 of the present invention is distributed on the surface of the urination chamber 8 along the axial direction of the catheter. The two ends of each linear electrode are fixed through the axially distributed pairs of holes in the elastic tube wall of the urination cavity, and the linear electrode corresponding to the tube wall between the two holes is provided with a concave hole in the elastic tube wall of the part of the urination cavity. Groove 2-1, this groove keeps the catheter surface smooth and allows the linear electrode to be positioned. The junction of each linear electrode and its lead wire is provided with a bending section 2-3 whose length i...

Abstract

The invention belongs to the medical apparatus relating to a straight electrode catheter of prostate therapeutic equipment for curing the prostate. Wherein, the surface of emiction cavity of catheter has been arranged with straight electrodes along its axis while the two ends of each straight electrode are individually through and fixed into the relative holes of the flexible pipe wall of the emiction cavity; electrode wires which is integrated with the electrode, inside the catheter cavity and educed from the port of catheter cavity are arranged on the one end of straight electrode, while one group of similar polarity electrode wires are arranged with insulating tube; and another end of straight electrode has a stop-motion rotary bended clasp connected to the tube wall of emiction cavity; the arrangement direction of straight electrode is the same as the insert-draw direction of catheter to decrease frictional resistance and markedly reduce the suffering of patient when inserting the catheter into the body; and the manufacturing process of straight electrode catheter is more easily than the ring electrode catheter. Said invention has simple structure with the advantage of significantly reduced the frictional resistance when inserting the catheter into body.

Description

technical field [0001] The invention belongs to medical equipment, and relates to a linear electrode urinary catheter for prostate treatment used in a prostate treatment instrument. Background technique [0002] The invention patent application with the application number of 98100200.5 discloses the structure of a surface electrode catheter, which is composed of a catheter and two sets of metal ring electrodes on the surface of the catheter, and the lead wires with insulating layers connecting the electrodes Clamped between the annular electrode and the urinary catheter, the lead wires of each electrode are introduced into the urination cavity from the lead wire hole made in the urination cavity of the catheter, and drawn out from the mouth of the cavity, and the lead wires of each electrode are connected to the socket of the therapeutic device through a plug. The electrode catheter can make full use of the existing catheter, and at the same time, each electrode is arranged ...
