DETAILED DESCRIPTION

[0034] The utility model embodiment provides a kind of adjustable intraoperative spinal cord monitoring electrode line guide sequence device, overcome the shortcoming that electrode line is crossed between background art, mutually entangled, interference, wiring confusion, difficult to classify, and surgical personnel is easily accidentally touched, electrode line is pulled, the needle tip of electrode line fixed on patient's body is accidentally pulled out by external force, and the technical effect that the precision of monitoring, reliability, effectiveness, safety are improved is realized.

[0035] The general idea of the technical scheme of the utility model embodiment is as follows:

[0036] The medical staff opens the openable cover of the lead sequence box, places the electrode wires one by one in the lead grooves, the positions of the electrode wires in the lead grooves correspond to the positions of the plugs of the electrode wires in the spinal cord monitoring device, and then the openable cover is closed, so that the multiple electrode wires are led in sequence, and the problems of crossing, mutual entanglement, interference, wiring disorder and difficult classification of the multiple electrode wires are effectively solved. The lead sequence box is fixed on the operating bed by the clamp, the medical staff fixes the needle tips of the multiple electrode wires at the specified positions of the patient's body, then takes the magic tape from the magic tape storage cavity of the base of the lead sequence box, and uses the magic tape to fix the multiple electrode wires between the needle tips and the lead sequence box, and the magic tape also abuts against the lead sequence box.

[0037] When the medical staff moves between the operating bed and the stimulating box or the amplifier of the spinal cord monitoring device, the electrode wires are accidentally touched and pulled due to negligence, fatigue and other factors, but since the magic tape abuts against the lead sequence box, the electrode wires are prevented from moving towards the lead sequence box, so that the needle tips of the electrode wires fixed on the patient's body are prevented from being accidentally pulled out by external force.

[0038] The electrode wires that are too long between the needle tips and the lead sequence box can also be wound into a coil shape and then tightly fixed by the remaining magic tape, so that the length of the electrode wires is adjusted, and the problems of crossing, mutual entanglement, interference, wiring disorder and difficult classification of the multiple electrode wires are more effectively solved.

[0039] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings of the specification and specific embodiments.

[0040] Reference Figures 1 to 8 The preferred embodiment of the utility model.

[0041] A adjustable intraoperative spinal cord monitoring electrode wire lead sequence device, comprising:

[0042] The lead sequence box 1, the clamp 2, the magic tape 3 and the electrode wire 4;

[0043] The lead sequence box 1 includes a base 11 and an openable cover 12, one side of the openable cover 12 is hinged to one side of the base 11, the other side of the openable cover 12 is connected to the other side of the base 11 through a buckle 15, the upper surface of the base 11 is provided with lead grooves 13, a plurality of lead grooves 13 are arranged at intervals, the lower surface of the base 11 is provided with a magic tape storage cavity 14, and the clamp 2 is fixedly arranged on the base 11.

[0044] The electrode wire 4 slides through the lead groove 13, the wire end of the electrode wire 4 has a needle tip 41, the magic tape 3 fixes the multiple electrode wires 4 between the needle tip 41 and the lead sequence box 1, and the magic tape 3 also abuts against the lead sequence box 1.

[0045] The beneficial effects of this technical solution are that the multiple electrode wires 4 are respectively slid through the multiple wire grooves 13 of the guide box 1 to guide the multiple electrode wires 4, effectively solving the crossing, mutual entanglement, interference, wiring disorder, and difficult classification of the multiple electrode wires 4 between the guide box 1 and the patient's body 7.

[0052] When the electrode wires passing through the lead box 1 are used for the lower limbs of the patient's body 7, multiple magic tapes 3 are used to fix the multiple electrode wires, and the electrode wires are divided into two groups to distinguish the left and right sides of the limbs. Figure 7 , the magic tape 3 is divided into a first magic tape 31, a second magic tape 32, a third magic tape 33 and a fourth magic tape 34, and the multiple electrode wires 4 are divided into a first group of electrode wires and a second group of electrode wires between the needle tip 41 and the lead box 1, the first magic tape 31 and the second magic tape 32 both fix the first group of electrode wires, the first magic tape 31 abuts against the lead box 1, and the second magic tape 32 is close to the needle tip 41 of the first group of electrode wires, and the third magic tape 33 and the fourth magic tape 34 both fix the second group of electrode wires, the third magic tape 33 abuts against the lead box 1, and the fourth magic tape 34 is close to the needle tip 41 of the second group of electrode wires.

[0053] The beneficial effects of this technical solution are that the first magic tape 31 and the third magic tape 33 are both used to prevent the electrode wires 4 from moving towards the lead box 1; the second magic tape 32 and the fourth magic tape 34 both use magic tapes to divide the electrode wires 4 into two groups, which are used to adjust the length of the electrode wires 4 drawn out to adapt to different fixed positions of the needle tip 41 on the patient's body 7, and help to classify the wiring.
