Abstract
The utility model relates to an electrode urine catheter of prostate therapeutic instrument. The annular electrode is composed of closely wound metallic fiber material. The end head of the annular electrode corresponding to a directing end of the urine catheter, is provided with a horizontal thrusting needle parallel to the axial line of the annular electrode. The horizontal thrusting needle is provided with a bending segment which has the corresponding length with the thickness of the pipe wall of the urination cavity. The connecting end of the electrode of each electrode lead is provided with a buckled knot which is larger than the pin hole of the urination cavity. The horizontal thrusting needle arranged on the body of the urination cavity makes each annular electrode relatively fixed on the urine catheter, preventing the annular electrode from moving or falling off when pulling out the electrode urine catheter from the body of the patient. The buckled knot arranged on the electrode connecting end of each electrode lead can effectively prevent disengaging of the electrode connecting end of the electrode lead from the annular electrode when pulling the electrode lead. The utility model has the advantages of simple structure and reliable effect of preventing falling off of the annular electrode.
Description
Technical field
This utility model belongs to medical apparatus and instruments, relates to a kind of electrical urethral catheter that is used for medical apparatus for treating prostatic diseases.
Background technology
Application number is that 98100200.5 application for a patent for invention discloses another electrical urethral catheter structure, 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 and catheter adopt the connected mode of frictional engagement, can not get rid of the possibility that electrode comes off when extracting electrical urethral catheter from patient body.In addition, each contact conductor is clamped between electrode and the catheter, can not get rid of the generation that lead-in wire and electrode break away from situation.
Summary of the invention
This utility model is above-mentionedly more than two groups there is metal ring electrode and the contact conductor technical problem of hidden danger that comes off in the electrical urethral catheter of annular electrode in order to solve, and a kind of a kind of electrical urethral catheter that can eliminate described hidden danger 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: by close rich each annular electrode that constitutes of metal wire rod, the termination of its corresponding catheter tapered guide head is provided with the horizontal contact pin that is parallel to the annular electrode axis, the joint portion of annular electrode and horizontal contact pin be provided with length with urinate that lumen wall thickness adapts, perpendicular to the bending section of horizontal contact pin, the electrode link setting of each contact conductor is greater than the button knot of the chamber fairlead of urinating.
This utility model can also be taked following technical measures:
Described horizontal contact pin places the chamber cavity of urinating via the chamber fairlead of urinating.
The beneficial effects of the utility model and advantage are: place the horizontal contact pin of the chamber cavity of urinating to make each annular electrode relative fixed in catheter; horizontal contact pin can stop annular electrode to move when promptly extracting electrical urethral catheter from patient body, therefore can guarantee that annular electrode does not come off.The setting of the electrode link button of contact conductor knot can effectively prevent the contact conductor that causes because of the pulling contact conductor and the disengaging of annular electrode.The utlity model has the outstanding reliably advantage of simple in structure, anti-annular electrode falling-off effect.
Description of drawings
Accompanying drawing 1 this utility model overall structure partial cutaway schematic.
Accompanying drawing 2 Figure 1A are to partial structurtes section enlarged diagram.
Drawing explanation: 1 catheter tapered guide head, 2 catheters, 3 annular electrodes, 4 chambeies of urinating, 5 inducing QI chambeies, 6 contact conductors, 7 inducing QI chamber ports, 8 sheaths, 9 plugs, 10 bending sections, 11 button knots, 12 horizontal contact pins.
The specific embodiment
Further specify this utility model below in conjunction with embodiment and accompanying drawing thereof.
Embodiment as shown in Figure 1, catheter 2 main bodys that silica gel or rubber are made are made of the inducing QI chamber 5 and the chamber 4 of urinating, at the catheter main body suit on catheter 2 air bag tops and the annular electrode 3 of the fixing close rich formation of STAINLESS STEEL WIRE that is connected with treatment power supply " just ", " bearing " utmost point respectively, the number of every group of electrode is looked the focus situation and can be selected to be provided with, usually number equates to be provided with in pairs, and present embodiment is 2 counter electrode.The contact conductor 6 that connects each annular electrode is drawn from the chamber port 7 of urinating and is connected in plug 9, and the lead division of contact conductor 6 is provided with sheath 8.
The thin portion structure of Fig. 1 embodiment as shown in Figure 2, each annular electrode 3 is provided with horizontal contact pin 12 in the termination of its corresponding catheter tapered guide head 1, horizontal contact pin is provided with the bending section 10 perpendicular to horizontal contact pin that length equates with chamber 4 pipe thicknesses of urinating, and horizontal contact pin is towards catheter tapered guide head and place the chamber cavity of urinating.The electrode link setting of each contact conductor 6 is greater than the button knot 11 of the chamber fairlead of urinating.
Claims (2)
1. electrical urethral catheter, formed by catheter body, metal ring electrode, contact conductor and plug, it is characterized in that: by close rich each annular electrode that constitutes of metal wire rod, the termination of its corresponding catheter tapered guide head is provided with the horizontal contact pin that is parallel to the annular electrode axis, the joint portion of annular electrode and horizontal contact pin be provided with length with urinate that lumen wall thickness adapts, perpendicular to the bending section of horizontal contact pin, the electrode link setting of each contact conductor is greater than the button knot of the chamber fairlead of urinating.
2, electrical urethral catheter according to claim 1 is characterized in that: described horizontal contact pin places the chamber cavity of urinating via the chamber fairlead of urinating.
