BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a neural monitoring device and a method of manufacturing the same, and more particularly, to a neural monitoring device that can prevent damage to nerves by using a surgical instrument during surgery .

As shown in Fig. 1, a very large number of nerve tissues (A) are distributed in the human body. Peripheral nerves, in particular, can include neurons that transmit sensations, as well as nerves that transmit movements such as muscles and organs.

Therefore, it is possible to directly confirm the state of the nerve by conducting a nerve conduction study which electrically stimulates the nerve, and in the case of the nerve that transmits the movement of the muscles like the peripheral nerve, the electromyogram (EMG: Electromyography).

On the other hand, it is necessary to prevent nerve breakdown by confirming the nerve during surgery so that these nerves are not cut off during surgical operation such as incision or cutting of the lesion as in surgical operation.

As disclosed in the prior art (Korean Patent Laid-Open No. 10-2012-0010221), in order to accurately confirm the reaction of the nerve, the nerve can be monitored by fixing the nerve using the nerve electrode in the form of a forceps.

However, the neural electrode described in the prior art may be suitable for monitoring the state of a specific nerve, but it is difficult to connect the nerve electrode to each nerve because different nerves may be continuously exposed during the operation for cutting or cutting the lesion .

In addition, since a long time can be used to connect each nerve using a nerve electrode, the total operation time is long.

Therefore, the current sensing part 150 can be fixed to the body part 100 by the fixing part 450.

Meanwhile, the current sensing unit 150 may be formed of a conductive wire and an insulating sheath formed therein, and the wire W or tape may also have an insulation effect.

One end of the current sensing part 150 may be located at one end 170a of the extension part 170 and the other end may extend to the handle 160 of the body part 100 to be connected to the alarm part 200. [

The current applied to the nerve is transmitted to the current sensing unit 150 through the current sensing unit 150 located at the one end 170a of the extension 170. At this time, Which can be sensed by the alarm unit 200.

Therefore, it can be confirmed that the portion where the body part 100 is in contact is a nerve through the signal generated in the alarm part 200. [

10 and 11, a current sensing unit 150 includes a body unit 100, a current sensing unit 150, a current sensing unit 150, And may be inserted into the through hole 100a communicating with the outside.

FIG. 12 is a perspective view showing a neural monitoring device according to a fourth embodiment of the present invention, and FIG. 13 is a view showing a manufacturing process of the neural monitoring device according to the fourth embodiment of the present invention.

12 and 13, in the present embodiment, the neural monitoring device of the present invention is implemented by utilizing various kinds of forceps scissors that have been commercially available.

Specifically, the neural monitoring device in this embodiment includes the forceps shears 1000, the first insulating layer 1000b, and the coupling portion 1100. [

Various types of forceps or scissors that are commercially available can be used for the forceps shears (1000). And the scissors themselves must be made of a conductive material, since they must form a path through which current flows. The wire 1200 may be connected to the forceps shears 1000. And the electric wire is connected to the notification unit 200 of the embodiment.

That is, when the distal end of the forceps 1000 is brought into contact with the nerve or the muscle at the time of the procedure as in the above embodiment, the current flows into the forceps 1000 through the front end 1000a of the forceps 1000 . Then, the force is transmitted to the notification unit 200 through the electric force 1200 through the forceps 1000 of the conductive material, so that the operator can recognize the notification signal.

The first insulating layer 1000b may be formed by disposing a forceps (not shown) other than the front end 1000a such that a current flowing through the nerve or muscle flows only through the front end 1000a of the forceps 1000, 1000).

The insulating layer 1000b is not formed in the portion where the electric wire 1200 is connected to the forceps 1000 in order to allow current to flow to the electric wire 1200. [ Various methods can be considered for this purpose. This portion will be described later in the description of the coupling portion 1100.

That is, the first insulating layer 1000b provides a path for minimum current movement of the forceps shears 1000. [ Therefore, the practitioner can perform the procedure while the current is insulated. Further, even if the other part of the forceps shears 1000 except for the front end 1000a of the forceps 1000 contacts the patient's nerves or muscles, the current does not flow and a signal through the notification unit 200 is not generated. Therefore, the practitioner can perform the procedure more accurately.

The coupling portion 1100 is coupled to the forceps shear, and the electric wire 1200 through which the current flows through the front end portion is coupled.

The coupling portion 1200 may be formed in various structures that allow the user to conveniently connect the wires. For example, as shown in FIG. 6 of the above embodiment. The electric wire may be coupled to the coupling portion 160a through a separate socket-shaped coupling portion 400a.

In this case, the protruded engaging portion 160a is formed of a conductive material. An insulating layer may not be formed on the coupling portion 160a and an insulating layer may be formed on the rest of the forceps except for the coupling layer 160a.

The coupling portion 1100 in this embodiment is also formed of a conductor. An insertion hole 1100a to which the electric wire 1100 is connected is formed. It is produced as a separate member and joined to the forceps by welding or the like. Here, the electric wire 1200 may be formed in various shapes for being inserted and fixed in the insertion hole 1100a.

A second insulating layer may be formed on the remaining portion except for the inner circumferential surface of the insertion hole 1200a. When the electric wire 1200 is inserted into the insertion hole 1100a, the current flowing into the front end 1000a of the forceps 1000 through the inner peripheral surface of the insertion hole 1200a, which is not insulated, The light is blurred to the electric wire 1200 only through the wire.

On the other hand, the engaging portion 1100 may be coupled to various portions of the forceps shears 1000, but in the present embodiment, in the vicinity of the distance adjusting portion formed to adjust the distance between the pair of grip portions of the forceps shears And is formed to have a shorter length than the distance adjusting portion.

Therefore, interference is minimized when a practitioner puts his / her finger in the grip and minimizes interference with the grip, so that even when the forceps 1000 is completely folded, interference by the grip does not occur.

That is, the neural monitoring device of the present embodiment uses the forceps of the generally used conductor material as it is, and only the coupling portion 1100 is produced, thereby coupling to the forceps shears that are produced. An advantage of the present invention is that it is possible to implement a device capable of performing a procedure without damaging the nerve or muscles by a simple process of applying a coating material by spraying or the like to other portions except for at least a part of the front end portion 1000a and the coupling portion 1100 have.

The process of manufacturing the forceps shears 1000 of the present embodiment will be described in more detail as follows.

First, the forceps shears 1000 of the conductor material, which are conventionally mass-produced and supplied, are selected. Then, the remaining portion except the front end 1000a of the foil shear 1000 and at least a part of the coupling portion 1100 is coated with an insulating material.

Specifically, in the application process, a portion where the ends of the front end portion 1000a and the connection portion 1100 are connected is shielded while being surrounded by a vinyl sheet or the like, and an insulating layer may be formed by spraying the insulating material with a stray type or the like will be.

In this embodiment, the insertion hole 1100a is formed in the coupling portion 1100, and only the insertion hole 1100a is not coated with the insulating material. Accordingly, the insulative material may be applied to the insertion hole 1100a while the insertion hole 1100a is closed with the sealing member S, so that the insulative material is not coated inside the insertion hole 1100a during the application process.

As a result, even in the manufacturing process of the neural monitoring device of the present embodiment, the manufacturing process can be simplified by adopting the coupling part in consideration of the convenience of the coating operation.

Fig. 14 is a cross-sectional view of a forceps shear in a fifth embodiment of the present invention, and Fig. 15 is a cross-sectional view of a forceps shear in a modification of the fifth embodiment of the present invention.

Referring to FIGS. 14 and 15, the forceps 2000 of the present embodiment is formed of an insulating material such as plastic. And a through hole 2000a is formed therein. The through hole 2000a is exposed at the front end of the forceps shears 2000. [

The electric wire 2200 is inserted into the through hole 2000a and is exposed to the outside through the through hole 2000a. Meanwhile, the through hole 2000a may be formed from the handle-receiving portion to the front end of the forceps shears 2000 and may be formed as a through hole having a short distance from the side of the front end of the forceps 2000 ' 2200a 'may be formed.

In other words, in the present embodiment, without having the structure of the coupling part for connecting the electric wires as in the fourth embodiment, it is possible to directly connect the body of the human body through the wire exposed through the front end of the forceps 2000, The current applied to the nerve or muscle is injected.

In addition, the forceps shears 2000 of the present embodiment can be easily manufactured through injection of an insulative material such as plastic into a mold. Specifically, the wire is fixed so as to be exposed to the front end of the forceps shears 2000 in a mold having cavities formed therein to implement the shape of the forceps shears 2000.

Then, the forceps of this embodiment can be easily manufactured through a process of injecting an insulating material into the mold. If the forceps are made of plastic or the like as in the present embodiment, it can be manufactured at low cost. Therefore, it is possible to manufacture a disposable forceps scissor that can be used for one operation.

16 is a perspective view of a forceps shears according to a sixth embodiment of the present invention. Referring to FIG. 16, the present embodiment further includes a coupling portion 3300 for fixing the electric wire 3200 to the forceps shears. Like the fifth embodiment, the forceps shears 3000 may be formed of an insulating material.

The engaging portion 3300 fixes the electric wire 3200 to the front end of the forceps shears 3000 so that the electric wire can be positioned at the front end portion of the forceps shears 3000. The engaging portion 3300 may be formed in various shapes for fixing the electric wire 3200 and is formed in the shape of a letter "C" in this embodiment. The electric wire 3200 is fixed to the side of the forceps shears 3000 The electric wire 3200 is fixed while being inserted into the forceps shears 3000 in the state of FIG.
