Description

Technical Field

[0001] This utility model relates to the field of electrophysiological catheter technology, and more specifically, to an electrophysiological electrode catheter structure. Background Technology

[0002] Electrophysiological electrode catheters are important tools for clinical cardiac electrophysiological examinations. They consist of a proximal connector, a catheter, and an electrode ring at the front end. The inner layer is made of radiopaque polyamide, the middle layer is a mesh of copper wire, the outer layer is polyurethane, and the ring electrode is made of platinum-iridium alloy. It has good conductivity and is not easily damaged. It can transmit the electrical impulses from the pulse generator to the heart and stimulate it, while recording cardiac electrical activity. It is the intermediate link between the pacemaker or recorder and the heart.

[0003] Existing electrophysiological electrode catheters are usually disposable sterile products, but they are expensive to manufacture and very troublesome to recycle. Therefore, the existence of an electrophysiological electrode catheter structure is crucial to solve the above problems. Utility Model Content

[0004] The main technical problem solved by this invention is to provide an electrophysiological electrode catheter structure that can solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, an electrophysiological electrode catheter structure includes a catheter body, a plurality of tubing is fixedly disposed inside the outer shell, the outer shell is tightly fitted on the outside of the catheter body, a handle connector is fixedly disposed at one end of the outer shell, the handle connector is electrically connected to the tubing, three sets of electrode plates are evenly disposed at one end of the catheter body, and electrode conductive plates are fixedly disposed on the outside of each of the three sets of electrode plates at one end of the outer shell, the inner sides of the three electrode conductive plates are respectively tightly fitted to the three sets of electrode plates, and an inlet head is threadedly connected to the other end of the outer shell.

[0006] Furthermore, two ablation heads are fixedly disposed on the outer side of the catheter body between the three sets of electrode plates, and ablation conductive plates are fixedly disposed on the top of the two sets of ablation heads on the outer side of the outer shell. Insulating layers are respectively disposed between the electrode conductive plates and the ablation conductive plates, as well as between the electrode plates and the ablation heads on the outer side of both the outer shell and the outer side of the catheter body.

[0007] Furthermore, four slots are provided on the outer side of the catheter body between the three sets of electrode plates and the two sets of ablation heads, and four blocks are fixedly provided on the inner side of the outer shell between the electrode conductive plates and the ablation conductive plates. The four blocks are slidably connected to the inner side of the four slots respectively.

[0008] Furthermore, the inlet head has a semi-circular head fixed at the end away from the outer shell and a smooth surface on the outer side.

[0011] Furthermore, a stop block is fixedly provided at one end of the catheter body between the clamping block and the sealing block, and the two sides of the stop block are tightly fitted to the clamping block and the sealing block respectively.

[0012] The beneficial effects of the electrophysiological electrode catheter structure of this utility model are as follows:

[0013] By setting up an outer shell and electrode conductive plates, the outer shell protects the main body of the catheter during use, and the electrode conductive plates extend the conductive surface of the electrode plates, allowing physiological electrode information to be detected through the electrode conductive plates. At the same time, after single use, the electrode catheter can be reused by disassembling and replacing the outer inlet head and outer shell. This facilitates material recycling and achieves a certain degree of reuse, improving the practicality of the structure.

[0014] By designing the ablation head and electrode pads, diagnosis and ablation can be performed using the same catheter under special circumstances, avoiding infection caused by changing catheters and further improving practicality. The slots and blocks facilitate the disassembly and replacement of the outer shell, while ensuring the precise fit between the electrode conductive pads, ablation conductive pads, and ablation head. The introduction head improves the smoothness of use, the external threaded cylinder effectively improves the structural tightness, the sealing block effectively improves the structural sealing performance, and the stop block effectively improves the structural stability.
