Safe and intelligent ablation main machine combined with nerve monitoring

Abstract

The invention relates to a safe and intelligent ablation main machine combined with nerve monitoring. The safe and intelligent ablation main machine comprises an ablation needle interface, a nerve monitoring interface, a main control module, a signal switching module, an ablation module and a nerve monitoring module, wherein a radio frequency output circuit and the output end of a stimulating circuit are connected to the ablation needle interface through the signal switching module, the main control module is respectively connected with the signal switching module, the ablation module and thenerve monitoring module, the signal switching module comprises a relay, the switching signal end of the relay is respectively connected with the ablation module and the nerve monitoring module, and acontrol signal of the relay is connected with the main control module. An ablation electrode of the radio frequency ablation needle is used as a stimulation electrode for nerve monitoring, a stimulation electrode does not need to be independently and additionally arranged, a special ablation needle does not need to be independently produced, intermittent work is realized during radio frequency ablation and nerve monitoring, and the monitoring effect can be greatly improved; and when the device performs ablation, in the puncture and ablation process, if nerves are about to be damaged, an alarmis given in advance to prevent damage.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a safe and intelligent ablation host combined with nerve monitoring. Background technique [0002] During radiofrequency ablation, it is easy to injure the nerves near the patient's lesion. Therefore, operations with complex nerve distribution near the lesion require intraoperative nerve monitoring to prevent nerve damage. However, the existing ablation surgery requires an independent nerve monitoring host for monitoring. In use, not only stimulation electrodes are added, which leads to inconvenient use, but also there is no organic combination of the two. Therefore, various explorations have been carried out in the industry. For example, the utility model patent: ablation electrode with nerve detection function (notification number: CN207384320U) considers the ablation electrode with nerve monitoring function. However, this utility requires the doctor to manually pr...

Problems solved by technology

However, due to the direct connection, the current during the ablation process will also stimulate the nerves, and the stimulation amplitude to the nerves is greater than that output by the nerve monitor, which makes it difficult to measure nerves accurately in this case.
