The present invention relates to a multi-interfacing based neural monitoring system, a neurostimulation multiple connection box for the same, and an electrical relay for connecting a neurostimulation-electrosurgical instrument, and more particularly, to a multi- A plurality of connection boxes in which a plurality of nerve probes respectively connected to instruments (metal surgical instruments, endoscopic surgical instruments, robot surgical instruments, energy device surgical instruments, etc.) are simultaneously connected are provided, It is necessary to remove the neural probe from the immediately preceding use surgical instrument to the currently used surgical instrument or to remove the neural probe connected to the immediately previous use surgical instrument from the connection box and to connect the neuro probe connected to the currently used surgical instrument to the connection box And the speed and convenience of surgery and neurological confirmation are improved. Meanwhile, the electrical relay connected to the nerve probe and the electrosurgical instrument is connected to the endoscopic surgical instrument or the robotic surgical instrument, so that the neural probe or the electrosurgical instrument is electrically connected to the surgical instrument according to the switching operation of the electrical relay, It is possible to alternate the use of the neuroradiograph and electrosurgical instrument without physical replacement of the electrosurgical instrument, thereby minimizing inconvenience / inconvenience / time-consuming due to replacement of the neuron probe / electrosurgical operator during surgery, and continuous confirmation when the electrosurgical instrument is not used A neurostimulation multi-connection box for the same, and an electrical relay for connecting a neurostimulation-electrosurgical instrument, which is capable of minimizing the risk of nerve injury and enabling rapid operation.

Neurological damage during surgery is an important complication in many surgical operations including ENT surgery, thoracic surgery, orthopedic surgery, brain surgery, spine surgery, sentinel surgery, and parotid surgery. It is very important to prevent. Therefore, an intraoperative neural monitoring system can be used to prevent nerve injury during surgery.

The neuromonitoring system during surgery uses neuro-EMG, which gives electrical stimulation to the suspected nervous tissue and evaluates the muscle movement of the body tissue using EMG. Here, the intraoperative nerve monitoring system requires a nerve probe that can provide electrical stimulation distinct from the surgical instrument.

In this case, the nerve probe may be connected to an interface connector box provided in the nerve monitoring system during surgery to stimulate the nerve. In the currently used nerve monitoring system, one nerve probe connection Terminal is formed and only one nerve probe can be used.

On the other hand, various surgical instruments can be used during surgery. Examples of surgical instruments used during surgery include general metal instruments, endoscopic instruments, and energy devices. It is possible to independently attach and detach the nerve probe to such a surgical instrument. In the present operation, the nerve monitoring system can use only one nerve probe. In order to use various surgical instruments, the connection between the nerve probe and the interface connection box is repeatedly changed There is a hassle to do. For example, when using a neural probe for a metal instrument, a neuro probe for an endoscope, or a neural probe for an energy device surgical instrument, it is inconvenient to change the neural probe itself connected to the connection terminal of the interface connection box.

If hemostasis or amputation of the body tissue is required during surgery, the electrosurgical instrument is connected to the surgical instrument and a high current power source is applied to the body tissue requiring hemostasis or amputation. For this purpose, the neuron probe connected to the surgical instrument is removed from the surgical instrument for neural confirmation, and then the electrosurgical instrument is connected to the surgical instrument. In addition, when the hemostasis or amputation of the body tissue by the electrosurgical instrument is completed, the neural probe is reconnected to the surgical instrument. Such a replacement operation between the nerve probe and the electrosurgical instrument during surgery has disadvantages such as inconvenience and inconvenience, and also increases the operation time.
