Radio-frequency generating therapeutic apparatus applied to cardiac radio-frequency ablation therapy

Abstract

The invention discloses a radio-frequency generating therapeutic apparatus applied to cardiac radio-frequency ablation therapy. The apparatus comprises a housing, and a power module, a radio-frequencygenerating unit and an electro-physiology recording unit are arranged in the housing; the power module is used for supplying electric energy to the radio-frequency generating unit and the electro-physiology recording unit; the radio-frequency generating unit comprises a power control module, a low-voltage adjustable DC power supply, a power inverter, a high-frequency power transformer, a back electrode and a radio-frequency ablation catheter; the power control module is connected to other parts of the radio-frequency generating unit; the low-voltage adjustable DC power supply is used for conducting constant-voltage output in a voltage variable mode; the power inverter is used for transforming inputted DC voltage into a corresponding high-frequency AC power signal; and the high-frequency power transformer is used for coupling the signal onto the radio-frequency ablation catheter and the back electrode. According to the radio-frequency generating therapeutic apparatus provided by the invention, the size and volume of a cardiac electro-physiology diagnosis and treatment system can be diminished, and connecting relations of the various parts can be simplified; therefore, the apparatusis more stable and lower in failure rate.

Description

technical field [0001] The present invention relates to the field of cardiac electrophysiological therapy, and more particularly relates to a radiofrequency generation therapy device for cardiac radiofrequency ablation therapy. Background technique [0002] The mainstream method of cardiac interventional therapy is to obtain local excitation signals from the surface of the heart with the help of interventional catheters. After analyzing the signals through instruments and equipment, the surgeon determines the cause of the disease, and then delivers radiofrequency energy to the heart tissue through the interventional catheter. middle. [0003] At present, the commonly used equipment in cardiac interventional surgery is multi-channel electrophysiological recorder system and cardiac radiofrequency ablation instrument. The target area releases high-frequency electric energy, which heats up the target tissue, denatures the protein and loses its activity, so as to achieve the pur...

Problems solved by technology

[0004] Among the currently disclosed products and technical solutions, the two devices are two independent products, and the two systems are connected through external interconnection wires, and the operator coordinates the operation. This method has brought many disadvantages: The interconnection is through a series of external cables, the wiring is complicated, and the connection is easily disturbed and damaged, which will affect the operation process

[0005] At the same time, the principle of traditional radio frequency energy generation technology generally adopts class A / B amplifiers, which have low efficiency and serious heat generation. Radio frequency ablation equipment is often bulky and heavy, causing it to occupy limited operating room space. In addition, independent ablation equipment and related Connecting cables require frequent maintenance, and the cost of transportation and storage is high

[0006] In addition, the two devices are often produced by different manufacturers, and the two systems are generally incompatible, and the information cannot be integrated. Therefore, the perspective of the surgeon needs to be switched between the electrophysiological recorder and the radiofrequency ablation system, which may easily cause operator fatigue
