Abstract
The utility model relates to a flexible surface electrode urine catheter used for prostate therapeutic instrument. The surface of the urine catheter is provided with interphase metal wire spiral electrodes. One end of each electrode is provided with an electrode lead which is incorporate with the electrode and positioned on the urine catheter cavity and extracted from the port of the urine catheter cavity, wherein, one electrode lead is provided with an insulating sheath. The spiral electrode is provided with elastic deformation ability and can adapt to focal sizes by increasing the length. By micro-adjusting the output current and electric voltage of the therapeutic equipment, the shortage that the surface area of the spiral electrode is a bit smaller than the public known annular electrode can be overcome. Thus the utility model can effectively solve the contradictory between the surface electrode urine catheter improving the therapeutic effect and the flexibility of the urine catheter. In addition, the integral structure of the spiral electrode and the electrode lead eliminates the existing defect of the hidden danger of falling off of the public known annular electrode. The utility model has the outstanding advantages of simple structure and evident effect of improving the flexibility of the surface electrode urine catheter.
Description
Technical field
This utility model belongs to medical apparatus and instruments, relates to a kind of flexible surface electrical urethral catheter that is used for medical apparatus for treating prostatic diseases.
Background technology
Application number is the structure that 98100200.5 application for a patent for invention discloses a kind of surface electrode catheter, it is made of catheter and two groups of metal ring electrodes that are located at the catheter surface, the cable guide that has insulating barrier that connects each electrode is held between annular electrode and the catheter, each contact conductor imports the chamber and draw from its accent of urinating from urinate fairlead that the chamber makes of catheter, and each contact conductor is connected in the socket of therapeutic instrument by plug.This electrical urethral catheter can make full use of existing catheter, and each electrode is arranged on the catheter outside simultaneously, and structure is comparatively simple.The more important thing is the bigger more than two groups of this electrical urethral catheter to annular electrode and lesion tissue contact area, materials such as the water in the tissue, electrolyte will be by abundant ionization, the positive and negative ion that is produced forms strong acid and highly basic district respectively at the positive and negative electrode district, not only make lesion tissue produce liquefaction necrosis at cathode chamber, make lesion tissue produce coagulation necrosis simultaneously in the anode region, so the electrochemical therapeutic therapeutic effect is more remarkable.But the metal ring electrode of above-mentioned electrical urethral catheter is to be made of the coiling of tinsel solid matter, more than two groups to the flexibility that must influence catheter that is provided with of tinsel solid matter coiling annular electrode.Therefore take to increase number of electrodes and improve the outstanding obstacle that the flexibility of therapeutic effect and catheter becomes raising surface electrode catheter performance.
Summary of the invention
This utility model is in order to solve the above-mentioned technical problem that influences the catheter flexibility that more than two groups the surface electrode catheter of annular electrode is existed, and a kind of flexible surface electrical urethral catheter is provided.
This utility model is taked following technical scheme for solving the above-mentioned technical problem that more than two groups the electrical urethral catheter of annular electrode is existed: the alternate catheter surface that is arranged at of tinsel screw electrode, each electrode one end is provided with and the contact conductor electrode one, that be positioned at the catheter cavity and draw from its port, and wherein one group of contact conductor is provided with insulated sleeve.
This utility model can also be taked following technical measures:
The joint portion of described each screw electrode and its contact conductor be provided with length and catheter urinate the chamber wall thickness suitable, perpendicular to the bending section of contact conductor.
Described each screw electrode, it is with respect to the other end that one contact conductor one end is set, and is provided with to be arranged in the urinate contact pin in chamber of catheter.
The insulated sleeve that described one group of contact conductor is provided with is the inducing QI chamber cavity of catheter.
The beneficial effects of the utility model and advantage are: the tinsel screw electrode has the elastic deformability who is suitable for catheter, increase the size that its length can adapt to focus, trace adjusts the therapeutic instrument output current and voltage can be mended the deficiency that the screw electrode surface area is slightly less than known annular electrode by Mi, and the trace adjustment of therapeutic instrument output current and voltage is sophisticated treatment control method, so this utility model can effectively solve the contradiction between the flexibility that the surface electrode catheter improves therapeutic effect and catheter.In addition, screw electrode and contact conductor integral structure have also been eliminated the defective that there is the hidden danger that comes off in known annular electrode.The utlity model has simple in structure, improve the outstanding advantage of the flexible obvious results of surface electrode catheter.
