Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a special double-needle electrode for endoscopic thyroid and parathyroid surgeries.
Background
Recurrent laryngeal nerve injury is one of the most common complications of thyroid and parathyroid gland operations, unilateral injury can cause hoarseness and has great influence on professionals such as teachers, announcers and singers; bilateral recurrent laryngeal nerve injury can cause dyspnea, and a long-term banded tube may be required to be cut through a trachea, so that the quality of life is seriously affected, and therefore recurrent laryngeal nerve injury is also one of the most common reasons for thyroid gland and parathyroid gland surgical medical procedure.
Advances in human anatomy knowledge and surgical techniques have led to a significant reduction in the probability of recurrent laryngeal nerve injury, but the authoritative literature reports: the injury rate of the recurrent laryngeal nerve caused by thyroid and parathyroid gland operations can still reach 2.3 percent. Therefore, how to protect the recurrent laryngeal nerve function in the operation is one of the key points and difficulties in thyroid and parathyroid gland operations, the currently accepted gold standard is to find and identify the continuity and integrity of the recurrent laryngeal nerve appearance by naked eyes in the operation, but the continuity and integrity of the recurrent laryngeal nerve does not represent the intact function, the intraoperative nerve monitoring technology has been widely applied clinically as an important assistant for the protection of the recurrent laryngeal nerve function, and both national and foreign authoritative industry guidelines suggest: the intraoperative nerve monitoring technology is used in the operation of high-risk thyroid and parathyroid gland to reduce the injury of recurrent laryngeal nerves.
