Ablation needle and monitoring system for monitoring recurrent laryngeal nerves

Abstract

The invention relates to an ablation needle and monitoring system for monitoring recurrent laryngeal nerves, wherein the ablation needle comprises an electrically conductive needle tip, an electrically conductive needle rod and an insulating needle handle. The front end of the electrically conductive needle rod is connected with the electrically conductive needle tip, and the back end of the electrically conductive needle rod is connected with the insulating needle handle; the electrically conductive needle rod is externally provided with an insulating layer, and the outer wall of the insulating needle handle is connected with a probe wire and a main machine wire. The monitoring system also comprises a nerve monitor, an ablation main machine and a gas pipe guide pipe; the ablation needle is electrically connected with the nerve monitor through the probe wire and is electrically connected with the ablation main body through the main body wire; the gas pipe guide pipe is provided with arecording electrode, and the recording electrode is electrically connected with the nerve monitor. The ablation needle and the monitoring probe are co-trunked, and not only is the structure simplified, but also monitoring and ablation are synchronously carried out during the ablation process. The monitoring effect is accurate and ideal, and the use is safe. When ablation treatment is finished, thepurpose of instant judging the functional state of the recurrent laryngeal nerves can be achieved by stimulating vagus nerves or the recurrent laryngeal nerves, and the postoperative recurrent laryngeal nerve function is predicted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ablation needle capable of monitoring the recurrent laryngeal nerve and a monitoring system. Background technique [0002] There are multiple groups of nerves passing through the neck of the human body. In the surgical treatment of neck diseases, it is necessary to effectively protect important nerve tissues in order to protect the patient's function and reduce surgical complications. The recurrent laryngeal nerve branches out from the vagus nerve, reflexes to both sides of the trachea in the neck, ascends close to the thyroid gland, enters the laryngeal cavity near the lower corner of the thyroid cartilage, and manages the laryngeal muscles except the cricothyroid muscle. Human nerve tissue cannot regenerate. If the recurrent laryngeal nerve is injured during the operation, it will lead to immobility of the vocal cords, hoarseness, and a serious reduction in the quali...

AI Technical Summary

Problems solved by technology

Since the recurrent laryngeal nerve and vagus nerve are only 1-3mm in diameter, they are closely attached to the surrounding tissue and cannot be displayed on the ultrasound image

Doctors can judge whether the recurrent laryngeal nerve is damaged after ablation by talking with the patient to understand the changes in their voice during the operation. However, once the patient’s voice becomes hoarse, the damage to the recurrent laryngeal nerve has already occurred, and such a judgment cannot protect neural purpose
