Description

Technical Field

[0001] The utility model relates to the field of nerve detection devices used for thyroid surgery, in particular to a nerve detection device used for thyroid surgery. Background Art

[0002] Recurrent laryngeal nerve injury during thyroid surgery is a common clinical complication. Patients mainly experience hoarseness caused by unilateral recurrent laryngeal nerve injury and difficulty breathing or even suffocation caused by bilateral recurrent laryngeal nerve injury. In particular, permanent nerve damage is often difficult to recover once a nerve rupture occurs. In thyroid surgery, nerve detection is an important technology used to protect important nerve structures such as the recurrent laryngeal nerve to prevent them from being damaged during surgery.

[0003] During the operation, doctors use nerve detection instruments to monitor the electrophysiological signals of the recurrent laryngeal nerve, which can reflect the functional status of the nerve. When the instrument detects that the nerve is damaged or about to be damaged, the doctor will take appropriate measures to protect the nerve.

[0004] The current nerve detection devices used in thyroid surgery are not timely and accurate in detecting the recurrent laryngeal nerve, and lack the technical means to actively stimulate the recurrent laryngeal nerve for immediate detection. During the detection process, the detection unit is easy to move, affecting the detection effect, and even worse, it may scratch the laryngeal muscle tissue. Utility Model Content

[0026] How the nerve detection device used in thyroid surgery works:

[0027] The nerve detection unit 210 and the nerve stimulation unit 220 are compactly positioned on the catheter 200 and do not interfere with each other's work, and both have an expanded state and a non-expanded state; the nerve detection unit 210 and the nerve stimulation unit 220 in the expanded state fit the catheter 200 and can penetrate deep into the throat of the surgical patient; after the catheter 200 arrives at the designated position, the nerve detection unit 210 and the nerve stimulation unit 220 start the expanded state, and the detection electrodes on the nerve detection unit 210 and the stimulation electrodes on the nerve stimulation unit 220 press against the laryngeal muscle tissue and keep their positions fixed, while leaving gaps around them to facilitate the flow of surrounding air; the nerve detection unit 210 is used to detect the electrical signal of the recurrent laryngeal nerve in real time, and the nerve stimulation unit 220 releases the electrical stimulation signal according to the instructions of the medical staff, electrically stimulates the nerve to be monitored during the operation and generates action potentials, and immediately stimulates the recurrent laryngeal nerve, so that the nerve detection unit 210 can detect the electrical signal of the recurrent laryngeal nerve more accurately.

[0028] In this embodiment, the expandable / contractible nerve detection unit and nerve stimulation unit at the front end of the catheter are extended into the patient's larynx to perform accurate real-time detection of the recurrent laryngeal nerve. The recurrent laryngeal nerve response can also be instantly detected through active stimulation, and the position is kept fixed to ensure the surrounding air flow, thereby avoiding damage to the recurrent laryngeal nerve during the operation.

[0029] The nerve detection unit 210 includes: the nerve detection unit 210 is sleeved on the outside of the catheter 200; the fixed end 211 of the detection unit is sleeved on the outside of the catheter 200, and its relative position with the catheter 200 remains unchanged; the movable end 212 of the detection unit is sleeved on the outside of the catheter 200, and can move along the axis of the catheter 200; the fixed end 211 of the detection unit is connected to the movable end 212 of the detection unit by a carrier belt 214, and a detection electrode 213 is provided on the carrier belt 214 for detecting the electrophysiological signal of the recurrent laryngeal nerve, so as to perform continuous nerve monitoring of the recurrent laryngeal nerve during thyroid surgery.

[0031] The material of the stimulation wire 224 includes conductive metal or alloy, and the outside of the stimulation wire 224 is covered with an insulating sleeve or coating. The stimulation wires 224 are arranged circumferentially around the catheter 200 at relatively dense intervals. When the neurostimulation unit 220 is in an expanded state, there is sufficient spacing between adjacent stimulation wires 224 to ensure that the stimulation electrodes 223 are against the recurrent laryngeal nerve during this period and do not contact each other.

[0032] In this embodiment, the nerve detection unit and the nerve stimulation unit are flexible in expansion / contraction and can penetrate deep into the patient's throat and firmly press against the throat muscles, leaving gaps for the surrounding air to flow.
