Non-intrusive penetration type radio frequency diagnosis and treatment device

Abstract

The invention discloses a non-intrusive penetration type radio frequency diagnosis and treatment device. The non-intrusive penetration type radio frequency diagnosis and treatment device comprises a radio frequency power supply, an intelligent controller and a front conduit, wherein the front conduit is internally provided with a cooling system composed of a telescoping cavity, the outer side of the cooling system is provided with an electrode array, the electrode array takes a flexible thin film as a carrier, one end of the flexible thin film is fixed on the outer surface of the front conduit, the other end is not fixed, the outer side of the electrode array is provided with a protective sleeve for protecting the electrode array in successfully going into an organ and protecting the organ from physical damage; the radio frequency power supply is connected with the electrode array through the intelligent controller; the radio frequency electrode array abuts against a tissue surface and maintains close contact with the tissue surface under the pressure effect of the flexible telescoping cavity, and thus good electric contact is formed; and the cooling system protects the surface tissue of a nearby area covered by the electrode array to enable the surface tissue from a passivation effect of radio frequency power.

Description

technical field [0001] The invention relates to the field of medical electronic equipment, in particular to a non-invasive and permeable radio frequency diagnosis and treatment device attached to the body surface or cavity for radio frequency treatment. Background technique [0002] Radiofrequency therapy has many cutting-edge applications in medicine, and radiofrequency power is applied through radiofrequency electrodes attached to the tissue surface. Generally speaking, radiofrequency treatment does not require surgery, is simple and convenient, and the treatment time is short. This method has been widely used in the treatment of kidney and heart, but it is mainly used in the treatment of tumor and cancer. However, radiofrequency treatment is rarely used in large cavities, such as bladder, uterus and so on. Taking the treatment of bladder as an example, the treatment device used must be inserted through the small urethral opening and then penetrate deep into the bladder....

AI Technical Summary

Problems solved by technology

The biggest disadvantage of the unipolar electrode structure is that the RF power is too concentrated on one point of the probe, and the power distribution around it shows an exponential decline. If it is too concentrated, it will cause great damage to the tissue near the probe contact point.

In addition, the probe-in-type structure can easily cause resistance in patients
