Electrode catheter and processing method thereof

Abstract

The invention discloses an electrode catheter and a processing method thereof. The electrode catheter comprises a catheter body, a connecting wire and a plurality of conductors, and a catheter channeland at least 1 first channel are formed in the catheter body along the length of the catheter body. Each conductors is integrally formed by an electrode and a conductive wire, the electrode is connected to one end of the conductive wire, and the inner radius of the electrode is less than or equal to the outer radius of the catheter body. The other ends of the plurality of conductive wires penetrate the side wall of the catheter body respectively at intervals to enter the first channel and the catheter channel, and the plurality of electrodes are fastened to the catheter body at intervals in the length direction of the catheter body. One end of each conductive wire penetrating the catheter body extends far away from the electrode in the first channel and the catheter channel and stretchesout of the corresponding side walls of the first channel and catheter channel, and the plurality of electrodes respectively form positive electrodes and negative electrodes. The processing method doesnot involve welding, soldering, flux and electric soldering irons, is environmentally friendly, has no pollution to the environment, and has no harm to human health.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an electrode catheter and a processing method thereof. Background technique [0002] Electrochemical treatment for benign prostatic hyperplasia is an effective method. The electrochemical prostate treatment instrument consists of a treatment instrument host and a catheter with electrodes inserted into the patient's prostate. The catheter with electrodes is the therapeutic instrument and the catheter. The lesion constitutes a low-voltage closed circuit, a key component for implementing electrochemical therapy, and is also a key component that affects the effect of electrochemical therapy. The invention patent with the application number of 2004100202387 discloses a processing method of an electrode catheter. The electrode is fixed by a vertical needle with a thickness equivalent to the wall thickness of the catheter. Although it plays a certain role in fixing, but in ...

The invention patent with the application number of 2004100202387 discloses a processing method of an electrode catheter. The electrode is fixed by a vertical needle with a thickness equivalent to the wall thickness of the catheter. Although it plays a certain role in fixing, but in During actual use, the electrode has been detached from the catheter body, and if the electrode catheter is forcibly removed from the patient, it will cause a certain degree of damage to the prostate, that is, it will be taken out together with the tissue near the lesion; At the same time, the process of inserting the vertical needle into the catheter wall is complicated and easily causes air leakage
