[0002] The intraoperative neuromuscular electrical stimulation monitoring electrode cartridge is a medical device component used for intraoperative neurological function protection, used in conjunction with an intraoperative neuromuscular electrical stimulation monitor. By monitoring neuromuscular electrical activity, the electrode cartridge provides surgeons with real-time feedback, helping to identify and protect critical neural structures and reduce the risk of nerve damage during surgery. It is an essential tool in modern precision medicine.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

The main unit 1 includes an upper shell 11, an upper shielding cover 12, a main board 13, a lower shielding cover 14, and a lower shell 15. The connecting cable 2 includes a monitor interface 21 and a connecting cable electrode interface 22.

[0023] In this embodiment, an upper shielding cover 12 that matches the shape of the upper shell 11 is fixed in the upper shell 11, a lower shielding cover 14 is placed at the bottom of the upper shielding cover 12, and the lower shielding cover 14 is fixed to the upper shell 11. A mainboard 13 is fixed in the shielding cavity surrounded by the upper shielding cover 12 and the lower shielding cover 14, and a plurality of electrode sockets 131 are arranged on the mainboard 13. Each electrode socket 131 is sequentially passed through the upper shielding cover 12 and the upper shell 11. The upper shell 11 is docked and fixed with the lower shell 15 to seal the upper shielding cover 12 and the lower shielding cover 14, and a film 3 is affixed to the top surface of the upper shell 11.

[0024] The upper shielding cover 12 and the lower shielding cover 14 are both made of nickel silver shielding covers, which helps to further improve the shielding effect.

[0025] In this embodiment, one end of the wiring 2 is provided with a monitor interface 21 for connecting to an intraoperative neuromyoelectric stimulation monitor, and the electrode box electrode interface 4 electrically connected to the main board 13 is passed through the upper shielding cover 12 and the upper shell 11 and fixed, and the other end of the connecting line 2 is provided with a connecting line electrode interface 22 connected to the electrode box electrode interface 4.

[0026] In this embodiment, first flanges 151 are provided on the upper portions of opposing sides of the lower housing 15, and second flanges 111 are provided on the upper portions of opposing sides of the upper housing 11. A binding post 19 for tying a strap is inserted and fixed between each first flange 151 and the corresponding second flange 111, and a gap is left between the first flange 151 and the corresponding second flange 111 to expose the binding post 19. The binding post 19 is a stainless steel cylinder. A strap can be attached to the binding post 19, which is then tied to other equipment, thereby tying the electrode cartridge to the other equipment. This helps free up the hands of medical personnel and reduces operational burden and inconvenience.

[0027] In this embodiment, the upper portion of the bottom surface of the lower housing 15 is provided with a hook hole 152 for hanging the host 1. The setting of the hook hole 152 is convenient for hanging the electrode box on other equipment, which helps to free the hands of medical staff and reduce the operational burden and inconvenience.

[0028] In this embodiment, the portable intraoperative neuromyoelectric stimulation monitoring electrode box is assembled as follows:

[0029] First, the motherboard 13, upper shielding cover 12, and upper housing 11 are assembled as follows: eight first mounting holes 132 are defined on the motherboard 13, second mounting holes 121 are defined at corresponding locations on the upper shielding cover 12, and first internally threaded studs 112 are fixed to corresponding locations within the upper housing 11. The upper shielding cover 12 is placed within the upper housing 11, and the motherboard 13 is then placed within the upper shielding cover 12. Eight first screws 16 are then inserted through the corresponding first mounting holes 132, second mounting holes 121, and first internally threaded studs 112, securing the motherboard 13, upper shielding cover 12, and upper housing 11. Each first screw 16 is an M3*6 cross-recessed pan head screw.

[0030] Then, the electrode box electrode interface 4 is welded to the main board 13 to achieve electrical connection, and the upper shielding cover 12 and the upper shell 11 are passed through and fixed in sequence. The electrode box electrode interface 4 is inserted with a connecting wire electrode interface 22 of the connecting wire 2, and the connecting wire 2 is connected to the main board 13 by welding and plugging.

[0031] The lower shielding cover 14 is then secured to the upper housing 11 by defining three third mounting holes 141 on the edge of the lower shielding cover 14, defining fourth mounting holes 122 at corresponding locations on the bottom edge of the upper shielding cover 12, and securing internally threaded second studs 113 at corresponding locations within the upper housing 11. Three second screws 17 are inserted through the corresponding third mounting holes 141, fourth mounting holes 122, and internally threaded second studs 113, respectively, and then screwed together to secure the lower shielding cover 14 to the upper housing 11. Each second screw 17 is an M3*6 cross-recessed pan head screw.

[0032] Finally, assemble the lower housing 15 and the upper housing 11. Each first flange 151 of the lower housing 15 is provided with a tie post 19, and the ends of the tie posts 19 are inserted into the corresponding second flange 111 of the upper housing 11. Four fifth mounting holes 153 are defined around the perimeter of the lower housing 15, and corresponding third studs 114 with internal threads are secured around the perimeter of the interior of the upper housing 11. Four third screws 18 are inserted through the corresponding fifth mounting holes 153 and the third studs 114 with internal threads, and then screwed together to secure the upper and lower housings 11 and 15 together, thereby sealing the upper and lower shielding covers 12 and 14. Each third screw 18 is an M3*10 cross-recessed pan head screw.

[0033] The utility model has a simple structure, is safe and reliable, and has a high-quality appearance. The internal parts of the electrode box are firmly installed, which expands the operating space during use and has the characteristics of flexibility and portability. When in use, it is only necessary to connect the electrode box to the intraoperative neuromyoelectric stimulation monitor through the interfaces at both ends of the connecting line 2. The operation is convenient and at the same time the function of intraoperative neuromyoelectric stimulation monitoring is realized at a distance from the detector. The electrode box is fixed and suspended by the hook hole 152 and the binding column 19, which reduces the burden of medical staff holding the electrode box for a long time. The upper shielding cover 12 and the lower shielding cover 14 of the electrode box are made of nickel silver material, which effectively improves the sealing and further improves the overall performance of the electrode box.

[0034] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
