Embodiment

[0023] This embodiment provides a kind of EEG equipment with radio frequency thermal coagulation, such as figure 1 and figure 2 As shown, it includes electrode 1, current generating device 2 and electroencephalograph 3;

[0024] The electrode 1 includes: a tube body 11, at least 6 annular metal contacts 12 (such as 6, 8, 10, 12, 15, 18 metal contacts) embedded in the outer wall of the tube body 11 and arranged side by side. Point 12), set in the tube body 11 at the position corresponding to the 3n+2th (2nd, 5th, 8th...) annular metal contacts 12 from the end of the tube body 11 Temperature sensors 13 are arranged at each place, wherein n is a natural number, 0, 1, 2..., and all ring metal contacts 12 are connected with the electroencephalograph 3 (the ring metal contacts 12 receive brain electrical signals and The electroencephalogram is displayed on the electroencephalograph 3);

[0025] The current generating device is used to receive the temperature value monitored by t...

Abstract

The invention relates to an electroencephalograph device with radio frequency thermocoagulation, comprising an electrode and a current generating device. The electrode comprises a tube body, at leastsix ring-shaped metal contacts arranged in parallel on the outer wall of the tube body, and a temperature sensor arranged in the tube body at positions corresponding to the 3n +2 ring-shaped metal contacts from the end of the tube body. The current generating device is configured to receive the temperature value monitored by the temperature sensor and to control the RF thermocondensation current to be formed between the ring metal contact corresponding to the temperature sensor and the one or two ring metal contacts closest to the ring metal contact or to be formed respectively. The RF thermocondensation current is generated by the RF thermocondensation current. The EEG device provided by the invention is provided with temperature sensors at positions corresponding to the 3n+2 ring-shapedmetal contacts, and a plurality of temperature sensors are arranged, so that the electrodes can monitor the temperatures of a plurality of parts, thereby performing radio frequency ablation accordingto the temperatures, and the performing parts are accurate.

Description

technical field [0001] The invention relates to an electroencephalogram device with radio frequency thermocoagulation, which belongs to the field of medical equipment. Background technique [0002] The intracranial electrode is a multi-contact electrode made of a special material. Its biggest advantage is that it can directly record the electrical activity of the deep brain and cerebral cortex, and is used for short-term intracranial implantation. Intracranial electrodes can generally be divided into deep electrodes, subdural strip electrodes, and grid-shaped cortical electrodes. The application of cortical EEG or deep EEG recorded by intracranial electrodes can eliminate the influence of structures such as scalp, skull, and dura mater on the recording of EEG activity; Influence of onset origin. When the epileptic focus is located near important functional areas such as movement and language, intracranial electrodes can also be used for cortical electrical stimulation mapp...
