Thyroid tumor radiofrequency ablation device based on recurrent laryngeal nerve detection

Abstract

The invention discloses a thyroid tumor radiofrequency ablation device based on recurrent laryngeal nerve detection. The thyroid tumor radiofrequency ablation device comprises a recurrent laryngeal nerve detecting instrument, a thyroid tumor radiofrequency ablation instrument and a detection and ablation integrated needle, wherein the recurrent laryngeal nerve detecting instrument and the thyroidtumor radiofrequency ablation instrument are both connected to the detection and ablation integrated needle, the detection and ablation integrated needle is used for recurrent laryngeal nerve detection when being independently connected with the recurrent laryngeal nerve detecting instrument and is used for ablating pathological tissues of the thyroid tumor when being independently connected withthe thyroid tumor radiofrequency ablation instrument. The thyroid tumor radiofrequency ablation device integrates recurrent laryngeal nerve detection and ablation of the pathological tissues of the thyroid tumor, enables the detection and ablation integrated needle to have a recurrent laryngeal nerve detecting function, firstly performs early warning of recurrent laryngeal nerve detection before ablation of a dangerous zone, avoids the possibility of thermal ablation injury of recurrent laryngeal nerve, accordingly improves the safety of thyroid tumor radiofrequency ablation, meanwhile can achieve two purposes through one needle, decreased puncture times and decreases traumas of patients.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a radio frequency ablation device for thyroid tumors based on detection of the recurrent laryngeal nerve. Background technique [0002] Because the recurrent laryngeal nerve is close to the back of the thyroid gland and is located in the dangerous triangle of the tracheoesophageal groove, it is very easy to damage the recurrent laryngeal nerve during radiofrequency ablation of the thyroid gland. At present, although the operation is performed under real-time monitoring under the guidance of ultrasound, the recurrent laryngeal nerve is difficult to identify under ultrasound. During the radiofrequency ablation process, the operator can only try to stay away from the dangerous triangle according to experience, so as to reduce the chance of injury to the recurrent laryngeal nerve. In this design, the radiofrequency ablation electrode is implanted with the recurrent laryngeal nerve dete...

Problems solved by technology

[0003] In addition, the detection needle and the ablation needle are punctured separately, which brings more pain to the patient, and the location of the lesion tissue without the recurrent laryngeal nerve is not accurately calibrated, and there is still a hidden danger of damage to the recurrent laryngeal nerve.
